自定義404
如果你想動態(tài)控制404的內(nèi)容時，例如在ajax請求時返回json數(shù)據(jù) {"code:"404", "msg":"404 not found"}，頁面請求時返回app/view/404.html模版，請參考如下示例
以下以php原生模版為例，其它模版
twigbladethink-tmplate原理類似
創(chuàng)建文件app/view/404.html
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>404 not found</title>
</head>
<body>
<?=htmlspecialchars($error)?>
</body>
</html>在config/route.php中加入如下代碼：
use support\Request;
use Webman\Route;
Route::fallback(function(Request $request){
// ajax請求時返回json
if ($request->expectsJson()) {
return json(['code' => 404, 'msg' => '404 not found']);
}
// 頁面請求返回404.html模版
return view('404', ['error' => 'some error'])->withStatus(404);
});自定義405
從webman-framework 1.5.23開始，回調(diào)函數(shù)支持傳遞status參數(shù)，如果status是404則代表請求不存在，405代表不支持當前請求方法(例如Route::post()設(shè)置的路由通過GET方式訪問)
use support\Request;
use Webman\Route;
Route::fallback(function(Request $request, $status) {
$map = [
404 => '404 not found',
405 => '405 method not allowed',
];
return response($map[$status], $status);
});自定義500
新建app/view/500.html
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>500 Internal Server Error</title>
</head>
<body>
自定義錯誤模版：
<?=htmlspecialchars($exception)?>
</body>
</html>新建app/exception/Handler.php(如目錄不存在請自行創(chuàng)建)
<?php
namespace app\exception;
use Throwable;
use Webman\Http\Request;
use Webman\Http\Response;
class Handler extends \support\exception\Handler
{
/**
* 渲染返回
* @param Request $request
* @param Throwable $exception
* @return Response
*/
public function render(Request $request, Throwable $exception) : Response
{
$code = $exception->getCode();
// ajax請求返回json數(shù)據(jù)
if ($request->expectsJson()) {
return json(['code' => $code ? $code : 500, 'msg' => $exception->getMessage()]);
}
// 頁面請求返回500.html模版
return view('500', ['exception' => $exception], '')->withStatus(500);
}
}配置config/exception.php
return [
'' => \app\exception\Handler::class,
];
