Laravel8路由问题解决方法

关于Laravel8路由问题的变动，不知道你是否有不习惯，反正我是不习惯。Laravel8中的路由按照我们之前的习惯来写，你会惊奇的发现，报错了。会产生一种摸不着头脑的感觉。

按照官方推荐的写法来编码自然是不会报错的，但是，如果还是按照Laravel8之前的写法来编码就有问题了。那么如何解决问题？

先来写写官方推荐的写法：

官方推荐写法

routes/web.php

IndexController 控制器文件

<span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(255, 121, 198)"><?</span><span style="box-sizing: border-box;color: rgb(1, 162, 82)">php</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(219, 45, 32)">namespace</span> <span style="box-sizing: border-box;color: rgb(226, 40, 127)">App\Http\Controllers</span>;</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(219, 45, 32)">use</span> <span style="box-sizing: border-box;color: rgb(1, 162, 82)">Illuminate\Http\Request</span>;</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box"></span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(219, 45, 32)">class</span> <span style="box-sizing: border-box;color: rgb(226, 40, 127)">IndexController</span> <span style="box-sizing: border-box;color: rgb(219, 45, 32)">extends</span> <span style="box-sizing: border-box;color: rgb(1, 162, 82)">Controller</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">{</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"> <span style="box-sizing: border-box;color: rgb(219, 45, 32)">public</span> <span style="box-sizing: border-box;color: rgb(219, 45, 32)">function</span> <span style="box-sizing: border-box;color: rgb(226, 40, 127)">index</span>() {</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">  <span style="box-sizing: border-box;color: rgb(219, 45, 32)">return</span> <span style="box-sizing: border-box;color: rgb(242, 176, 29)">'hello IndexController'</span>;</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"> }</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">    </span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"> <span style="box-sizing: border-box;color: rgb(219, 45, 32)">public</span> <span style="box-sizing: border-box;color: rgb(219, 45, 32)">function</span> <span style="box-sizing: border-box;color: rgb(226, 40, 127)">test</span>() {</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">  <span style="box-sizing: border-box;color: rgb(219, 45, 32)">return</span> <span style="box-sizing: border-box;color: rgb(242, 176, 29)">'test'</span>;</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"> }</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">}</span>

这是IndexController所对应的路由及其文件。如果现在有个文章控制PostController文件，那么就需要再路由文件中引入这个控制器，然后再定义相关的路由。要是有N多个控制器文件，那么就需要在web.php文件中引入N多个控制器，给人感觉就已经不简洁了。

web.php

<span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(255, 121, 198)"><?</span><span style="box-sizing: border-box;color: rgb(1, 162, 82)">php</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(219, 45, 32)">use</span> <span style="box-sizing: border-box;color: rgb(1, 162, 82)">App\Http\Controllers\PostController</span>;</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(219, 45, 32)">use</span> <span style="box-sizing: border-box;color: rgb(1, 162, 82)">App\Http\Controllers\TagController</span>;</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box"></span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(1, 162, 82)">Route</span>::<span style="box-sizing: border-box;color: rgb(1, 162, 82)">get</span>(<span style="box-sizing: border-box;color: rgb(242, 176, 29)">'post/lst'</span> , [<span style="box-sizing: border-box;color: rgb(1, 162, 82)">PostController</span>::<span style="box-sizing: border-box;color: rgb(219, 45, 32)">class</span> , <span style="box-sizing: border-box;color: rgb(242, 176, 29)">'index'</span>]);</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(1, 162, 82)">Route</span>::<span style="box-sizing: border-box;color: rgb(1, 162, 82)">get</span>(<span style="box-sizing: border-box;color: rgb(242, 176, 29)">'tag/lst'</span> , [<span style="box-sizing: border-box;color: rgb(1, 162, 82)">TagController</span>::<span style="box-sizing: border-box;color: rgb(219, 45, 32)">class</span> , <span style="box-sizing: border-box;color: rgb(242, 176, 29)">'index'</span>]);</span>

下面就是按照以前的写法的解决方法

Laravel8之前的写法

第一步：打开 App\Providers\RouteServiceProvider.php文件

第二步：添加属性

<span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(255, 121, 198)"><?</span><span style="box-sizing: border-box;color: rgb(1, 162, 82)">php</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box"></span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(219, 45, 32)">namespace</span> <span style="box-sizing: border-box;color: rgb(226, 40, 127)">App\Providers</span>;</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box"></span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(219, 45, 32)">use</span> <span style="box-sizing: border-box;color: rgb(1, 162, 82)">Illuminate\Cache\RateLimiting\Limit</span>;</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(219, 45, 32)">use</span> <span style="box-sizing: border-box;color: rgb(1, 162, 82)">Illuminate\Foundation\Support\Providers\RouteServiceProvider</span> <span style="box-sizing: border-box;color: rgb(219, 45, 32)">as</span> <span style="box-sizing: border-box;color: rgb(1, 162, 82)">ServiceProvider</span>;</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(219, 45, 32)">use</span> <span style="box-sizing: border-box;color: rgb(1, 162, 82)">Illuminate\Http\Request</span>;</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(219, 45, 32)">use</span> <span style="box-sizing: border-box;color: rgb(1, 162, 82)">Illuminate\Support\Facades\RateLimiter</span>;</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(219, 45, 32)">use</span> <span style="box-sizing: border-box;color: rgb(1, 162, 82)">Illuminate\Support\Facades\Route</span>;</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box"></span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(219, 45, 32)">class</span> <span style="box-sizing: border-box;color: rgb(226, 40, 127)">RouteServiceProvider</span> <span style="box-sizing: border-box;color: rgb(219, 45, 32)">extends</span> <span style="box-sizing: border-box;color: rgb(1, 162, 82)">ServiceProvider</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">{</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">    <span style="box-sizing: border-box;color: rgb(205, 171, 83)"># 添加该属性就可以按照之前习惯的写法编码了</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">    <span style="box-sizing: border-box;color: rgb(219, 45, 32)">protected</span> <span style="box-sizing: border-box;color: rgb(1, 160, 228)">$namespace</span> <span style="box-sizing: border-box;color: rgb(255, 121, 198)">=</span> <span style="box-sizing: border-box;color: rgb(242, 176, 29)">"App\Http\Controllers"</span>;</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"> ...</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">}</span>

第三步：实测

web.php

<span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(255, 121, 198)"><?</span><span style="box-sizing: border-box;color: rgb(1, 162, 82)">php</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box"></span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(219, 45, 32)">use</span> <span style="box-sizing: border-box;color: rgb(1, 162, 82)">Illuminate\Support\Facades\Route</span>;</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box"></span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(1, 162, 82)">Route</span>::<span style="box-sizing: border-box;color: rgb(1, 162, 82)">get</span>(<span style="box-sizing: border-box;color: rgb(242, 176, 29)">'test'</span> , <span style="box-sizing: border-box;color: rgb(242, 176, 29)">'IndexController@index'</span>);</span>
