前言

从今天开始将使用 Blazor 完成博客的前端开发，如果你不了解 Blazor ，建议你还是去微软官网学习学习基础知识。本篇不做普及，因为这是实战系列，重点是完成项目开发。

还有，在开始 Blazor 实战之前，建议动手完成之前的系列文章，这样更有连贯性，不至于懵圈。

因为我也是第一次使用 Blazor 开发项目，所以无法保证代码的最优性，如果有不对的地方，或者有更好的做法，欢迎大家指正，谢谢。

接下来，我将现学现做带来一个完整的博客项目，来吧，Just do it 。

我这里选择的是 Blazor WebAssembly，需要你有 .NET Core 3.1 的开发环境，并且你还要有 Visual Studio 2019 IDE。

给大家看看我的开发环境，终端工具是：Window Terminal ，配置一下用起来太爽了，五星强烈推荐。

搭建

Blazor WebAssembly 是一个单页应用框架，可用它通过 .NET 生成交互式客户端 Web 应用。Blazor WebAssembly 使用开放的 Web 标准(没有插件或代码转换)，适用于移动浏览器等各种新式 Web 浏览器。...

不啰嗦了，直接开干吧，在项目中新建 Blazor Web 应用。

然后将项目设置为启动项目，Ctrl+F5 运行一下看看，官网默认示例我这里也懒得说了，直接进入主题吧。

改造

我这里使用的UI还是我目前博客的样式，你可以选择任意你喜欢的UI界面，这部分就随意了，不是本实战系列的重点，所以有关样式这些东西我就直接 Ctrl CV 了。

替换下面css代码到 wwwroot/css/app.css 中。

在css中用到了开源的 FiraCode 字体，可以自己去下载，不过在css中我已经改为远程地址了。

删掉 wwwroot/sample-data、wwwroot/css/bootstrap、wwwroot/css/open-iconic 三个文件夹。

在wwwroot文件夹下，有一个index.html，这个是我们网站的入口，注意里面有一对标签：Loading...，这个标签里面的内容会在 wasm 加载完毕后自动清除掉，所以，一般可以用来做加载提示。

现在改造一下index.html，代码如下：

<html><head>    <meta charset="utf-8" />    <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no" />    <meta name="keywords" content="Meowv,qix,阿星Plus,个人博客">    <meta name="description" content="阿星Plus的个人博客,用于发表原创文章,关注微信公众号：『阿星Plus』了解更多。">    <title>?阿星Plus⭐⭐⭐title>    <base href="/" />    <link href="css/app.css" rel="stylesheet" />head><body>    <app>        <div class="loader">div>    app>    <script src="_framework/blazor.webassembly.js">script>body>html>

千万注意，blazor.webassembly.js 这个js不可以删除，会在项目打包后自动生成这个js文件。

然后我们一点一点完善，Program.cs默认就行暂时不需要做任何改动。

Pages文件夹内的Razor组件就是我们的具体页面了，干掉默认的Counter.razor和FetchData.razor，留下Index.razor，当作我们的首页。

Shared文件夹内可以放一些共享的组件，比如我们的模板MainLayout.razor就在里面，它需要继承LayoutComponentBase。

所以现在可以来修改一下我们的模板内容。

以我博客的UI架构而言，博客分为了三个部分，头部、尾部、内容。

@inherits LayoutComponentBase
