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：<app>Loading...</app>，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：

<!DOCTYPE html>
<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

<div class="wrapper">
  <header />
  @Body
  <footer />
</div>

@Body为固定语法，表示这里是内容部分，其他的不变，只在这里填充内容。

在 Shared 文件夹中添加两个组件，头部：Header.razor、尾部：Footer.razor。

Header.razor的内容如下：

<!-- Header.razor -->
<header>
  <nav class="navbar">
    <div class="container">
      <div class="navbar-header header-logo">
        <NavLink class="menu-item" href="/" Match="NavLinkMatch.All">
          😍阿星Plus
        </NavLink>
      </div>
      <div class="menu navbar-right">
        <NavLink class="menu-item" href="posts">Posts</NavLink>
        <NavLink class="menu-item" href="categories">Categories</NavLink>
        <NavLink class="menu-item" href="tags">Tags</NavLink>
        <NavLink class="menu-item apps" href="apps">Apps</NavLink>
        <input id="switch_default" type="checkbox" class="switch_default" />
        <label for="switch_default" class="toggleBtn"></label>
      </div>
    </div>
  </nav>
  <nav class="navbar-mobile">
    <div class="container">
      <div class="navbar-header">
        <div>
          <NavLink class="menu-item" href="" Match="NavLinkMatch.All"
            >😍阿星Plus</NavLink
          >
          <NavLink>&nbsp;·&nbsp;Light</NavLink>
        </div>
        <div class="menu-toggle">&#9776; Menu</div>
      </div>
      <div class="menu">
        <NavLink class="menu-item" href="posts">Posts</NavLink>
        <NavLink class="menu-item" href="categories">Categories</NavLink>
        <NavLink class="menu-item" href="tags">Tags</NavLink>
        <NavLink class="menu-item apps" href="apps">Apps</NavLink>
      </div>
    </div>
  </nav>
</header>

可以看到有很多的NavLink组件，这是我将 a 标签转换后的内容，其实最终生成的也是我们熟悉的 a 标签，不过他自然有独特用处，看介绍：

创建导航链接时，请使用 NavLink 组件代替 HTML 超链接元素 (<a>)。 NavLink 组件的行为方式类似于 <a> 元素，但它根据其 href 是否与当前 URL 匹配来切换 active CSS 类。 active 类可帮助用户了解所显示导航链接中的哪个页面是活动页面。
…

Footer.razor的内容如下：

<!-- Footer.razor -->
<footer id="footer" class="footer">
  <div class="copyright">
    <span>
      Powered by <a target="_blank" href="http://dot.net">.NET Core 3.1</a> and
      <a href="http://blazor.net/">Blazor</a> on Linux
    </span>
  </div>
</footer>

然后删掉默认的多余的组件：NavMenu.razor和SurveyPrompt.razor。

还有一个_Imports.razor，这个就是用来导入命名空间的，放在这里面就相当于全局引用了。

现在去编辑我们的首页Index.razor。

@page "/"

<div class="main">
  <div class="container">
    <div class="intro">
      <div class="avatar">
        <a href="javascript:;"
          ><img src="https://static.meowv.com/images/avatar.jpg"
        /></a>
      </div>
      <div class="nickname">阿星Plus</div>
      <div class="description">
        <p>
          生命不息，奋斗不止
          <br />Cease to struggle and you cease to live
        </p>
      </div>
      <div class="links">
        <NavLink class="link-item" title="Posts" href="posts">
          <i class="iconfont iconread"></i>
        </NavLink>
        <NavLink
          target="_blank"
          class="link-item"
          title="Notes"
          href="https://notes.meowv.com/"
        >
          <i class="iconfont iconnotes"></i>
        </NavLink>
        <NavLink
          target="_blank"
          class="link-item"
          title="API"
          href="https://api.meowv.com/"
        >
          <i class="iconfont iconapi"></i>
        </NavLink>
        <NavLink class="link-item" title="Manage" href="/account/auth">
          <i class="iconfont iconcode"></i>
        </NavLink>
        <NavLink
          target="_blank"
          class="link-item"
          title="Github"
          href="https://github.com/Meowv/"
        >
          <i class="iconfont icongithub"></i>
        </NavLink>
        <NavLink
          class="link-item weixin"
          title="扫码关注微信公众号：『阿星Plus』查看更多。"
        >
          <i class="iconfont iconweixin"></i>
        </NavLink>
        <div class="qrcode">
          <img src="https://static.meowv.com/images/wx_qrcode.jpg" />
        </div>
      </div>
    </div>
  </div>
</div>

@page指令用于设置页面路由地址，因为是首页，所以直接给一个”/“就可以了。

至此项目算是搭建完成并且将其改造了一番，现在可以去运行一下看看效果了。

第一次打开或者强制刷新页面会出现加载中的界面，我这里就是一个小圈圈在那里转，当加载完毕后就会自动消失，什么都不需要干，太方便了。

现在已经成功将首页的显示搞定了，随便点击几个按钮试试，会输出一个错误提示：Sorry, there’s nothing at this address，因为没有找到这些路由，所以就…

默认的有点丑，并且这句提示当然也可以自定义的，现在来看最后的一个组件App.razor。

<Router AppAssembly="@typeof(Program).Assembly">
  <Found Context="routeData">
    <RouteView RouteData="@routeData" DefaultLayout="@typeof(MainLayout)" />
  </Found>
  <NotFound>
    <LayoutView Layout="@typeof(MainLayout)">
      <p>Sorry, there's nothing at this address.</p>
    </LayoutView>
  </NotFound>
</Router>

通过语义化的代码不难理解，Found就是找到与之匹配的路由，然后调用模板MainLayout，NotFound就是没有找到的情况下，使用MainLayout并且在@body输出一句提示。

将这句错误提示做成一个公共的组件并且美化一下，在 Shared 文件夹下新建组件：ErrorTip.razor，内容如下：

<div class="main">
  <div class="post-wrap">
    <h2 class="eror-tip">Sorry, there's nothing at this address.😖😖😖</h2>
  </div>
</div>

使用组件也很简单，在App.razor中删掉默认的 p 标签然后调用ErrorTip。

...
<NotFound>
  <LayoutView Layout="@typeof(MainLayout)">
    <ErrorTip />
  </LayoutView>
</NotFound>
...

再看一下打开了不存在路由的页面的错误提示吧。

哈哈哈，是不是好看许多，接下来会完成主题切换，菜单展开关闭等等功能，其实这些可以用 JavaScript 很方便的实现，但是既然用了 Blazor 开发，所以还是用 .NET 代码实现吧。

本篇就先到这里，未完待续…
