不可预知得内部异常处理
<h2>应用异常处理类</h2>
<ul>
<li>/app/ExceptionHandle.php</li>
</ul>
<pre><code class="language-php">// 自定义异常消息处理，处理异常可以把代码逻辑写在这个方法里边
render($request, Throwable $e);</code></pre>
<h2>多应用时，使用应用异常处理类</h2>
<ul>
<li>控制器调用不存在的变量
<ul>
<li>/app/admin/controller/Index.php</li>
</ul></li>
</ul>
<pre><code class="language-php">/app/admin/controller/Index.php
namespace app\admin\controller;
use app\BaseController;
use app\Request;
class Index extends BaseController {
/**
* index.php/admin/Index/test
*/
public function test(Request $Request) {
// $this->acb;
throw new \think\exception\HttpException(404, '找不到相应的数据');
}
}</code></pre>
<h2>建立异常处理类</h2>
<ul>
<li>该文件主要参照/app/ExceptionHandle.php文件</li>
<li>/app/admin/exception/Http.php</li>
</ul>
<pre><code class="language-php">/app/admin/exception/Http.php
namespace app\admin\exception;
use think\exception\Handle;
use think\Response;
use Throwable;
class Http extends Handle{
public function render($request, Throwable $e): Response {
$httpStatus = method_exists($e, 'getStatusCode') ? $e->getStatusCode() : 500;
return return_data(config('statuscode.error'), $e->getMessage(), [], $httpStatus);
}
}</code></pre>
<h2>容器Provider定义文件</h2>
<ul>
<li>/app/admin/provider.php</li>
</ul>
<pre><code class="language-php">return [
'think\exception\Handle' => 'app\\admin\\exception\\Http',
];</code></pre>
<h2>访问url</h2>
<ul>
<li>域名/index.php/admin/Index/test</li>
</ul>
