Ruby发送电子邮件 (Ruby sending email)

Sending emails and routing email among mail servers are handled by Simple Mail Transfer Protocol commonly known as SMTP. Net::SMTP class is a predefined class in Ruby’s library which is purposefully defined for Simple Mail Transfer Protocol.

在邮件服务器之间发送电子邮件和路由电子邮件由通常称为SMTP的 简单邮件传输协议处理。 Net :: SMTP类是Ruby库中的预定义类，它是为简单邮件传输协议专门定义的。

Net::SMTP has two methods namely new and start. The parameter specification goes as follows,

Net :: SMTP有两种方法，即new和start。参数规格如下：

新： (new:)

It consumes two parameters, the first one is a server which is by default 'localhost' and the port number which is by default 25.

它使用两个参数，第一个是默认为“ localhost”的服务器，默认为25的端口号。

开始： (start:)

It consumes six parameters namely server, port, domain, account, password, and authtype. The default value of server is localhost, the port is 25, the domain is ENV["HOSTNAME"], account and password is nil and authtype is cram_md5.

它使用六个参数，即服务器，端口，域，帐户，密码和身份验证类型。服务器的默认值为localhost，端口为25，域为ENV [“ HOSTNAME”]，帐户和密码为nil，身份验证类型为cram_md5。

sendmail is a method of an SMTP object which takes three parameters namely The source, The sender and the recipient.

sendmail是SMTP对象的一种方法，它采用三个参数，即源，发件人和收件人。

Now, let us understand a very simple way to send one email using Ruby code. refer the example given below,

现在，让我们了解一种使用Ruby代码发送一封电子邮件的非常简单的方法。请参考下面的示例，

require 'net/smtp'
message = <<MESSAGE_END
From: Includehelp <[email protected]>
To: Hrithik sinha <[email protected]>
Subject: Urgent Information
Hello there, Greeting from Includehelp.
We hope, you are doing good. Have a great day.
Read articles at Includhelp for best programming guidance.
MESSAGE_END
Net::SMTP.start('localhost') do |smtp|
smtp.send_message message, '[email protected]', '[email protected]'
end

The code given above is a very basic way to send email using Ruby. We have integrated a very simple email message. It is required to take care of the format of headers properly. We all know that an email requires three things namely a From, To and Subject which should be identical from the body of an email with the help of a blank line.

上面给出的代码是使用Ruby发送电子邮件的一种非常基本的方法。我们已经集成了非常简单的电子邮件。需要正确处理标题格式。我们都知道，电子邮件需要三项内容，即“发件人”，“收件人”和“主题”，在空白行的帮助下，它们应与电子邮件正文相同。

For sending an email, we are supposed to use Net::SMTP class which allows us to connect with the SMTP server on our machine and then make use of send_message method with the message specified, the sender’s address and the receiver’s address as parameters.

为了发送电子邮件，我们应该使用Net :: SMTP类，该类允许我们与计算机上的SMTP服务器连接，然后使用send_message方法，并将指定的消息，发送者的地址和接收者的地址作为参数。

If you want to send an HTML file using Ruby script, that file will be treated as a normal document even after including HTML tags in the documents. Net::SMTP class provides you a feature to send an HTML message with the help of an email. Refer the following code for instance.

如果要使用Ruby脚本发送HTML文件，即使在文档中包含HTML标记后，该文件也将被视为普通文档。 Net :: SMTP类为您提供了借助电子邮件发送HTML消息的功能。例如，请参考以下代码。

require 'net/smtp'
message = <<MESSAGE_END
From: Hrihik Sinha <[email protected]>
To: Saksham Sharma <[email protected]>
MIME-Version: 1.0
Content-type: text/html
Subject: An exemplary email

hey bro,

嘿哥们儿，

This is an example. Read articles at Includehelp.com for better understanding of concepts.

这是一个例子。阅读Includehelp.com上的文章，以更好地理解概念。

<h1>Write heading here</h1>
<p>This is a paragraph</p>
<hr>
MESSAGE_END
Net::SMTP.start('localhost') do |smtp|
smtp.send_message message, '[email protected]', '[email protected]'
end

You are supposed to specify Mime version, the type of content and character set if you want to email an HTML text using Ruby script.

如果要使用Ruby脚本通过电子邮件发送HTML文本，则应指定Mime版本，内容类型和字符集。
