slack通知本地服务器_通过构建自己的Slack App学习无服务器

slack通知本地服务器

Serverless architecture is the industry's latest buzzword and many of the largest tech companies have begun to embrace it.

无服务器架构是业界最新的流行语，许多大型科技公司已开始采用它。

In this article, we'll learn what it is and why you should use it. We'll also set up AWS, create our serverless app, and create a slack app!

在本文中，我们将学习它的含义以及为什么要使用它。我们还将设置AWS，创建无服务器应用程序，并创建一个松弛应用程序！

什么是无服务器？ (What is Serverless?)

Serverless is a cloud computing paradigm in which the developer no longer has to worry about maintaining a server – they just focus on the code.

无服务器是一种云计算范例，开发人员无需在其中维护服务器，而只需关注代码。

Cloud providers, such as AWS or Azure, are now responsible for executing code and maintaining servers by dynamically allocating their resources. A variety of events can trigger code execution, including cron jobs, http requests, or database events.

现在，AWS或Azure之类的云提供商负责通过动态分配资源来执行代码和维护服务器。各种事件可以触发代码执行，包括cron作业，http请求或数据库事件。

The code that developers send to the cloud is usually just a function so, many times, serverless architecture is implemented using Functions-as-a-Service, or FaaS. The major cloud providers provide frameworks for FaaS, such as AWS Lambda and Azure Functions.

开发人员发送到云的代码通常只是一个功能，因此很多时候，无服务器架构是使用“功能即服务”或FaaS实现的。主要的云提供商提供了适用于FaaS的框架，例如AWS Lambda和Azure Functions。

为什么没有服务器？ (Why Serverless?)

Not only does serverless allow developers to just focus on code, but it has many other benefits as well.

无服务器不仅使开发人员可以专注于代码，而且还具有许多其他好处。

Since cloud providers are now responsible for executing code and dynamically allocate resources based on event triggers, you typically only pay per request, or when your code is being executed.

由于云提供商现在负责执行代码并根据事件触发器动态分配资源，因此您通常只按请求付费或执行代码时付费。

Additionally, since cloud providers are handling your servers, you don't have to worry about scaling up – the cloud provider will handle it. This makes serverless apps lower cost, easier to maintain, and easier to scale.

此外，由于云提供商正在处理您的服务器，因此您不必担心扩展问题–云提供商将处理它。这使无服务器应用程序成本更低，更易于维护且更易于扩展。

设置AWS Lambda (Setting up AWS Lambda)

For this tutorial, I will be using AWS Lambda, so first, we'll create an AWS account. I find AWS's UI hard to understand and difficult to navigate, so I will be adding screenshots for each step.

在本教程中，我将使用AWS Lambda，因此，首先，我们将创建一个AWS账户。我发现AWS的UI难以理解且难以导航，因此我将为每个步骤添加屏幕截图。

Once you log in, you should see this:

登录后，您应该会看到以下内容：

Next, we'll set up an IAM user. An IAM (Identity and Access Management) user interacts with AWS and its resources on your behalf. This allows you to create different IAM users with different permissions and purposes, without compromising the security of your root user account.

接下来，我们将设置一个IAM用户。 IAM (身份和访问管理)用户代表您与AWS及其资源进行交互。这使您可以创建具有不同权限和目的的不同IAM用户，而不会损害根用户帐户的安全性。

Click on the "services" tab at the top of the page, and type "IAM" into the bar:

单击页面顶部的“服务”选项卡，然后在栏中输入“ IAM”：

Click on the first result, and you'll see, on the left-hand sidebar, that you're at the dashboard. Click on the "Users" option to get to create our new IAM user.

单击第一个结果，您将在左侧边栏上看到位于仪表板。单击“用户”选项以创建我们的新IAM用户。

Click on the "Add user" button to create a new user. Fill in the details as follows:

单击“添加用户”按钮创建一个新用户。填写以下详细信息：

You can name your user anything you'd like, but I went with serverless-admin. Be sure that your user has "Programmatic access" to AWS, not "AWS Management Console Access". You'd use the latter for teammates, or other humans who need access to AWS. We just need this user to interact with AWS Lambda, so we can just give them programmatic access.

您可以根据需要命名用户，但是我使用serverless-admin 。确保您的用户具有对AWS的“程序访问”， 而不是 “ AWS管理控制台访问”。你会使用后者对谁需要访问AWS的队友，或者其他人。我们只需要该用户与AWS Lambda进行交互，因此我们可以为他们提供编程访问权限。

For permissions, I've chosen to attach existing policies since I don't have any groups, and I don't have any existing users that I want to copy permissions for. In this example, I will create the user with Administrator access since it's just for a personal project; however, if you were to use a serverless app in an actual production environment, your IAM user should be scoped to only access Lambda-necessary parts of AWS. (Instructions can be found here).

对于权限，由于没有任何组，并且没有要复制其权限的现有用户，因此我选择附加现有策略。在此示例中，我将创建具有管理员访问权限的用户，因为它仅用于个人项目。但是，如果要在实际生产环境中使用无服务器应用程序，则应将IAM用户的范围限定为仅访问AWS的Lambda必需部分。 (说明可在此处找到)。

I didn't add any tags and created the user. It's vital to save the information given to you on the next screen - the Access ID and Secret Access Key.

我没有添加任何标签并创建了用户。将提供给您的信息保存在下一个屏幕上至关重要-访问ID和秘密访问密钥。

Don't leave this screen without copying down both! You won't be able to see the Secret access key again after this screen.

不要在不抄袭两者的情况下离开此屏幕！在此屏幕之后，您将无法再次看到“秘密”访问密钥。

Finally, we'll add these credentials to command line AWS. Use this guide to get aws cli setup.

最后，我们将这些凭证添加到命令行AWS。使用本指南获取AWS CLI设置。

Make sure you have it installed by running aws --version. You should see something like this:

通过运行aws --version确保已安装它。您应该会看到以下内容：

Then run aws configure and fill in the prompts:

然后运行aws configure并填写提示：

I have the default region as us-east-2 already set up, but you can use this to determine what your region is.

我已经设置了默认区域，因为us-east-2已经设置好了，但是您可以使用它来确定您所在的区域。

To make sure that you have your credentials set up correctly, you can run cat ~/.aws/credentials in your terminal.

为了确保您正确设置了凭据，可以在终端中运行cat ~/.aws/credentials 。

If you want to configure a profile other than your default, you can run the command as follows: aws configure --profile [profile name].

如果要配置默认配置文件以外的配置文件，则可以按以下方式运行命令： aws configure --profile [profile name] 。

If you had trouble following the steps, you can also check out AWS's documentation.

如果您在执行步骤时遇到麻烦，还可以查看AWS文档。

设置无服务器 (Set up serverless)

Go to your terminal and install the serverless package globally using npm: npm i -g serverless. (More info on serverless here)and your terminal should look something like this:

转到终端并使用npm全局安装serverless软件包： npm i -g serverless 。 ( 有关无服务器的更多信息，请参见此处 )，您的终端应如下所示：

Next, navigate to the directory where you want to create the app, then run serverless and follow the prompts:

接下来，导航到您要在其中创建应用程序的目录，然后运行serverless并按照提示进行操作：

For this application, we'll be using Node.js. You can name your app anything you want, but I've called mine exampleSlackApp.

对于此应用程序，我们将使用Node.js。您可以根据自己的喜好为应用命名，但是我将其命名为exampleSlackApp 。

Open your favorite code editor to the contents in exampleSlackApp (or whatever you've called your application).

打开您最喜欢的代码编辑器，查看exampleSlackApp (或您所谓的应用程序)中的内容。

First, we'll take a look at serverless.yml. You'll see there's a lot of commented code here describing the different options you can use in the file. Definitely give it a read, but I've deleted it down to just:

首先，我们来看一下serverless.yml 。您会在这里看到很多注释代码，它们描述了可以在文件中使用的不同选项。一定要读一读，但是我已经将其删除为：

I've included region since the default is us-east-1 but my aws profile is configured for us-east-2.

由于默认值为us-east-1所以我包括了region ，但是我的aws配置文件配置为us-east-2 。

Let's deploy what we already have by running serverless deploy in the directory of the app that serverless just created for us. The output should look something like this:

让我们通过在serverless deploy serverless刚刚为我们创建的应用程序的目录中运行serverless deploy已有的serverless deploy 。输出应如下所示：

And if you run serverless invoke -f hello in your terminal, it'll run the app, and you should see:

并且，如果您在终端中运行serverless invoke -f hello ，它将运行该应用程序，您应该看到：

{"statusCode": 200,"body": "{\n  \"message\": \"Go Serverless v1.0! Your function executed successfully!\",\n  \"input\": {}\n}"
}

For further proof that our slack app is live, you can head back to AWS console. Go to the services dropdown, search for "Lambda", and click on the first option ("Run code without thinking about servers").

为了进一步证明我们的Slack应用程序是在线的，您可以返回AWS控制台。转到服务下拉菜单，搜索“ Lambda”，然后单击第一个选项(“运行代码而无需考虑服务器”)。

And here's your app!

这是您的应用！

Next, we'll explore actually using serverless by building our slack app. Our slack app will post a random Ron Swanson quote to slack using a slash command like this:

接下来，我们将通过构建我们的松弛应用程序来探索实际使用无服务器的情况。我们的Slack应用程序将使用如下斜杠命令将Ron Swanson随机报价发布到Slack：

The following steps don't necessarily have to be done in the order that I've done them, so if you want to skip around, feel free!

不一定必须按照我做的顺序来完成以下步骤，因此，如果您想略过一遍，请放心！

将API添加到我们的代码中 (Adding the API to our code)

I'm using this API to generate Ron Swanson quotes since the docs are fairly simple (and of course, it's free). To see how requests are make and what gets returned, you can just put this URL in your browser:

我使用此API生成Ron Swanson报价，因为这些文档非常简单(当然，它是免费的)。要查看请求的发出方式和返回的内容，您可以将以下URL放入浏览器中：

https://ron-swanson-quotes.herokuapp.com/v2/quotes

You should see something like this:

您应该会看到以下内容：

So, we can take our initial function and modify it as such:

因此，我们可以采用初始功能并将其修改为：

and getRon looks like:

getRon看起来像：

function getRon() {request('https://ron-swanson-quotes.herokuapp.com/v2/quotes', function (err, resp, body) {console.log('error:', err)console.log('statusCode:', resp && resp.statusCode)console.log('body', body)})
}

Now, let's check if it works. To test this code locally, in your terminal: serverless invoke local -f hello. Your output should look something like:

现在，让我们检查一下是否可行。要在本地测试此代码，请在您的终端中： serverless invoke local -f hello 。您的输出应类似于：

serverless invoke -f hello would run the code that you've deployed, as we saw in previous sections. serverless invoke local -f hello, however, runs your local code, so it's useful for testing. Go ahead and deploy using serverless deploy!

如前几节所述， serverless invoke -f hello将运行您已部署的代码。 serverless invoke local -f hello ，但是运行本地代码，因此对于测试非常有用。继续并使用serverless deploy ！

创建您的Slack应用 (Create your Slack App)

To create your slack app, follow this link. It'll make you sign into a slack workspace first, so be sure you're a part of one that you can add this app to. I've created a testing one for my purposes. You'll be prompted with this modal. You can fill in whatever you want, but here's what I have as an example:

要创建您的Slack应用，请点击以下链接。这将使您首先登录到一个松弛的工作区，因此请确保您是可以添加此应用程序的一部分。我已经为我的目的创建了一个测试。系统会提示您。您可以填写任何内容，但以下是我的示例：

From there, you'll be taken to the homepage for your app. You should definitely explore these pages and the options. For example, I've added the following customization to my app:

从那里，您将被带到应用程序的主页。您绝对应该浏览这些页面和选项。例如，我已将以下自定义添加到我的应用程序：

Next, we need to add some permissions to the app:

接下来，我们需要为应用添加一些权限：

To get an OAuth Access Token, you have to add some scope and permissions, which you can do by scrolling down:

要获取OAuth访问令牌，您必须添加一些范围和权限，您可以通过向下滚动来做到这一点：

I've added "Modify your public channels" so that the bot could write to a channel, "Send messages as Ron Swanson" so when the message gets posted, it looks like a user called Ron Swanson is posting the message, and slash commands so the user can "request" a quote as shown in the screenshot at the beginning of the article. After you save the changes, you should be able to scroll back up to OAuths & Permissions to see:

我添加了“修改您的公共频道”，以便该机器人可以将其写入频道“以Ron Swanson的身份发送消息”，这样，当该消息被发布时，它看起来就像一个名叫Ron Swanson的用户正在发布该消息，并使用斜杠因此用户可以“请求”报价，如本文开头的屏幕快照所示。保存更改后，您应该可以回滚到OAuths和Permissions来查看：

Click the button to Install App to Workspace, and you'll have an OAuth Access Token! We'll come back to this in a second, so either copy it down or remember it's in this spot.

单击按钮将应用程序安装到工作区，您将获得OAuth访问令牌！我们将在稍后再讨论，因此请复制下来或记住它在该位置。

连接代码和Slack应用 (Connect Code and Slack App)

In AWS Lambda, find your slack app function. Your Function Code section should show our updated code with the call to our Ron Swanson API (if it does not, go back to your terminal and run serverless deploy).

在AWS Lambda中，找到您的松弛应用程序功能。您的功能代码部分应显示对我们Ron Swanson API的调用的更新后的代码(如果没有，请返回到您的终端并运行serverless deploy )。

Scroll below that to the section that says "Environment Variables", and put your Slack OAuth Access Token here (you can name the key whatever you'd like):

滚动到显示“ 环境变量 ”的部分，然后在此处放置Slack OAuth访问令牌(您可以根据需要命名密钥)：

Let's go back to our code and add Slack into our function. At the top of our file, we can declare a const with our new OAuth Token:

让我们回到我们的代码并将Slack添加到我们的函数中。在文件的顶部，我们可以使用新的OAuth令牌声明const ：

const SLACK_OAUTH_TOKEN = process.env.OAUTH_TOKEN.

const SLACK_OAUTH_TOKEN = process.env.OAUTH_TOKEN 。

process.env just grabs our environment variables (additional reading). Next, let's take a look at the Slack API to figure out how to post a message to a channel.

process.env只是获取我们的环境变量( 其他阅读资料 )。接下来，让我们看一下Slack API，以了解如何将消息发布到频道。

The two pictures above I've taken from the API are the most relevant to us. So, to make this API request, I'll use request by passing in an object called options:

上面我从API拍摄的两张图片与我们最相关。因此，要发出此API请求，我将通过传入一个名为options的对象来使用request ：

let options = {url: 'https://slack.com/api/chat.postMessage',headers: {'Accept': 'application/json',},method: 'POST',form: {token: SLACK_OAUTH_TOKEN,channel: 'general', // hard coding for nowtext: 'I am here',}}

and we can make the request:

我们可以提出要求：

request(options, function(err, resp, body) {console.log('error:', err)console.log('statusCode:', resp && resp.statusCode)console.log('body', body)})

Finally, I'll wrap the whole thing in a function:

最后，我将整个内容包装在一个函数中：

function postRon(quote) {let options = {url: 'https://slack.com/api/chat.postMessage',headers: {'Accept': 'application/json',},method: 'POST',form: {token: SLACK_OAUTH_TOKEN,channel: 'general',text: quote,}}request(options, function(err, resp, body) {console.log('error:', err)console.log('statusCode:', resp && resp.statusCode)console.log('body', body)})
}

and we can call it from getRon like this:

我们可以像这样从getRon调用它：

function getRon() {request('https://ron-swanson-quotes.herokuapp.com/v2/quotes', function (err, resp, body) {console.log('error:', err)console.log('statusCode:', resp && resp.statusCode)console.log('body', body)postRon(body.substring(2, body.length - 2)) // here for parsing, remove if you want to see how/why I did it})
}

So our code should all in all look like this:

因此，我们的代码应该全部如下所示：

'use strict';
let request = require('request');const SLACK_OAUTH_TOKEN = process.env.OAUTH_TOKENmodule.exports.hello = (event) => {getRon();
};function getRon() {request('https://ron-swanson-quotes.herokuapp.com/v2/quotes', function (err, resp, body) {console.log('error:', err)console.log('statusCode:', resp && resp.statusCode)console.log('body', body)postRon(body.substring(2, body.length - 2))})
}function postRon(quote) {let options = {url: 'https://slack.com/api/chat.postMessage',headers: {'Accept': 'application/json',},method: 'POST',form: {token: SLACK_OAUTH_TOKEN,channel: 'general',text: quote,}}request(options, function(err, resp, body) {console.log('error:', err)console.log('statusCode:', resp && resp.statusCode)console.log('body', body)})
}

Now let's test! Unfortunately, our environment variable in AWS Lambda isn't available to us when we run serverless invoke local -f hello. There are a few ways you can approach this, but for our purposes, you can just replace the value for SLACK_OAUTH_TOKEN with your actual OAuth Token (make sure it's a string). But be sure you switch it back before you push it up to version control!

现在让我们测试！不幸的是，当我们运行serverless invoke local -f hello时，我们无法使用AWS Lambda中的环境变量。有几种方法可以解决此问题，但是出于我们的目的，您可以将SLACK_OAUTH_TOKEN的值替换为实际的OAuth令牌(确保它是字符串)。但是在将其推向版本控制之前，请确保将其切换回原来的状态！

Run serverless invoke local -f hello, and hopefully you should see a message like this in your #general channel:

运行serverless invoke local -f hello ，希望您应该在#general频道中看到如下消息：

Please note that I put down my channel name as 'general' since it's my test workspace; however, if you're in an actual workspace, you should create a separate channel for testing apps, and put the message there instead while you're testing.

请注意，由于它是我的测试工作区，因此我将频道名称记为“一般”。 但是，如果您在实际的工作空间中，则应创建一个单独的通道来测试应用程序，并在测试时在其中放置消息。

And in your terminal, you should see something like:

在终端中，您应该看到类似以下内容的内容：

If that works, go ahead and deploy it using serverless deploy. If it does not, the best way to debug this is to adjust code and run serverless invoke local -f hello.

如果可行，请继续使用serverless deploy 。如果不是，调试此错误的最佳方法是调整代码并运行serverless invoke local -f hello 。

添加斜线命令 (Adding slash command)

The last and final part is adding a slash command! Go back to your function's home page in AWS Lambda and look for the button that says "Add trigger":

最后也是最后一部分是添加斜杠命令！返回AWS Lambda中函数的主页，然后查找显示“添加触发器”的按钮：

Click on the button to get to the "Add trigger" page, and select "API Gateway" from the list:

单击按钮进入“添加触发器”页面，然后从列表中选择“ API网关”：

I've filled in the information based on defaults mostly:

我主要根据默认值填写了信息：

I've also left this API open for use – however, if you're using this in production, you should discuss what standard protocol would be with your team. "Add" the API, and you should receive an API endpoint. Hold on to this, because we'll need it for the next step.

我还开放了该API的使用权-但是，如果您在生产中使用此API，则应与您的团队讨论什么标准协议。 “添加” API，您将收到一个API端点。坚持下去，因为下一步将需要它。

Let's switch back over to our slack app and add a slash command:

让我们切换回我们的Slack应用程序并添加一个斜杠命令：

Click on "Create New Command" and it should pop up with a new window to create a command. Here's how I filled mine out:

单击“创建新命令”，它将弹出一个新窗口以创建命令。这是我填写我的方法：

You can enter anything you want for "command" and "short description" but for "request URL", you should put your API endpoint.

您可以为“命令”和“简短描述”输入任何内容，但对于“请求URL”，则应放置API端点。

Finally, we'll go back to our code to make some final adjustments. If you try to use the slash command, you should receive some kind of error back – this is because slack expects a response and AWS expects you to give a response when the endpoint is hit. So, we'll change our function to allow a callback (for reference):

最后，我们将返回到代码进行一些最终调整。如果您尝试使用slash命令，则应该返回某种错误-这是因为slack期望响应，而AWS期望在命中端点时做出响应。因此，我们将更改函数以允许callback ( 仅供参考 )：

module.exports.hello = (event,context,callback) => {getRon(callback);
};

and then we'll change getRon to do something with the callback:

然后我们将getRon更改为对callback执行一些操作：

function getRon(callback) {request('https://ron-swanson-quotes.herokuapp.com/v2/quotes', function (err, resp, body) {console.log('error:', err)console.log('statusCode:', resp && resp.statusCode)console.log('body', body)callback(null, SUCCESS_RESPONSE)postRon(body.substring(2, body.length - 2))})
}

where SUCCESS_RESPONSE is at the top of the file:

其中SUCCESS_RESPONSE位于文件顶部：

const SUCCESS_RESPONSE = {statusCode: 200,body: null
}

You can put the callback here or in postRon – it just depends on what your purposes are with the callback.

您可以在此处或在postRon放置回调-这仅取决于回调的用途。

Our code at this point now looks something like:

现在，我们的代码如下所示：

'use strict';
let request = require('request');const SLACK_OAUTH_TOKEN = OAUTH_TOKENconst SUCCESS_RESPONSE = {statusCode: 200,body: null
}module.exports.hello = (event,context,callback) => {getRon(callback);
};function getRon(callback) {request('https://ron-swanson-quotes.herokuapp.com/v2/quotes', function (err, resp, body) {console.log('error:', err)console.log('statusCode:', resp && resp.statusCode)console.log('body', body)callback(null, SUCCESS_RESPONSE)postRon(body.substring(2, body.length - 2))})
}function postRon(quote) {let options = {url: 'https://slack.com/api/chat.postMessage',headers: {'Accept': 'application/json',},method: 'POST',form: {token: SLACK_OAUTH_TOKEN,channel: 'general',text: quote,}}request(options, function(err, resp, body) {console.log('error:', err)console.log('statusCode:', resp && resp.statusCode)console.log('body', body)})
}

You should be able to use the /ron command in slack now and get a Ron Swanson quote back. If you don't, you can use Cloudwatch logs to see what went wrong:

您现在应该可以在松弛状态下使用/ron命令，并获得Ron Swanson的报价。如果没有，则可以使用Cloudwatch日志查看出了什么问题：

The way our code works now, we've hardcoded in the channel name. But, what we actually want is for the quote to get posted in the message where you used /ron.

现在，我们的代码工作方式已在渠道名称中进行了硬编码。但是，我们真正想要的是将报价张贴在您使用/ron的消息中。

So, we can now use the event portion of our function.

因此，我们现在可以使用函数的event部分。

module.exports.hello = (event,context,callback) => {console.log(event)getRon(callback);
};

Use /ron to run the function, and then check your Cloudwatch logs to see what gets logged to the console (you may need to refresh). Check on the most recent logs and you should see something like this:

使用/ron运行该功能，然后检查您的Cloudwatch日志以查看记录到控制台的内容(您可能需要刷新)。查看最新的日志，您应该看到类似以下内容的信息：

The first item in this list (where it says "resource", "path", etc.) is the event, so if you expand that, you'll see a long list of things, but what we're looking for is 'body' all the way down at the bottom:

该列表中的第一项(其上显示“资源”，“路径”等)是事件，因此，如果您扩展它，将会看到一长串的东西，但是我们要寻找的是“身体一直向下到底部：

Body is a string with some relevant information in it, one of them being "channel_id". We can use channel_id (or channel_name) and pass it into the function that creates our slack message. For your convenience, I've already parsed this string: event.body.split("&")[3].split("=")[1] should give you the channel_id. I hardcoded in which entry (3) the channel_id was for simplicity.

主体是一个包含一些相关信息的字符串，其中之一是“ channel_id”。我们可以使用channel_id(或channel_name)并将其传递到创建松弛消息的函数中。为了方便起见，我已经解析了此字符串： event.body.split("&")[3].split("=")[1]应该会给您channel_id。为了简单起见，我对channel_id的哪个条目(3)进行了硬编码。

Now, we can alter our code to save that string as a variable:

现在，我们可以更改代码以将该字符串保存为变量：

let channel = 'general' (as our fallback)

let channel = 'general' (作为我们的后备)

module.exports.hello = (event,context,callback) => {console.log(event)channel = event.body.split("&")[3].split("=")[1]console.log(context)getGoat(callback);
};

and in postRon:

并在postRon ：

Finally, if you use a slack command in any channel in your workspace, you should be able to see a Ron Swanson quote pop up! If not, as I mentioned before, the most common tools I use to debug serverless apps are serverless invoke local -f <function name> and Cloudwatch logs.

最后，如果您在工作空间的任何通道中使用松弛命令，那么您应该能够看到弹出的Ron Swanson报价！如前所述，如果没有，我用来调试无服务器应用程序的最常用工具是serverless invoke local -f <function name>和Cloudwatch日志。

Hopefully you were successfully able to create a functioning Slack application! I've included resources and background reading dispersed throughout the article and I'm happy to answer any questions you may have!

希望您能够成功创建一个正常运行的Slack应用程序！我在本文中分散了资源和背景知识，很高兴回答您可能遇到的任何问题！
