Blazor 实战系列（一）

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 (opens new window) ，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>

@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...
