我不应该得到404错误：laravel

Question

我开发了一个API，我在这个页面遇到问题我在路线中添加了它，总是遇到404错误我不知道为什么

我的控制器：

class InsertPPictureController extends Controller
{
    public function profilepicture (Request $request)
    {
        $input = $request->all();

        $validator =    Validator::make($input, [
            'id_user'=> 'required',
            'picture'=> 'image|nullable|max:1999'
        ] );

        $user = User::findOrFail($request->id);
        $user_id = $request->id ;

        if($request->hasFile('picture')){
            // Get filename with the extension
            $filenameWithExt = $request->file('picture')->getClientOriginalName();
            // Get just filename
            $filename = pathinfo($filenameWithExt, PATHINFO_FILENAME);
            // Get just ext
            $extension = $request->file('picture')->getClientOriginalExtension();
            // Filename to store
            $fileNameToStore= $user_id.'.'.$extension;
            // Upload Image
            $path = $request->file('picture')->storeAs('public/profilepic', $fileNameToStore);
            $user->pic_path = $fileNameToStore ;
            $user->update();


        } else {
            $fileNameToStore = 'noimage';
        }

        return response()->json(' Success : User updated with success ',200);
    }
}

这是我的api.php

Route::group(['middleware' => ['jwt.verify']], function() {
    Route::get('logout', 'AuthController@logout');
    Route::post('postcreditscards', 'CreditsCardsController@stockcards');
    Route::get('getcreditscards', 'CreditsCardsController@index');
    Route::get('getmybalance', 'MyBalanceController@index');
    Route::get('getuserdata', 'AuthController@getuser');
    Route::post('sendMoneyTransaction', 'MyBalanceController@updatebalance');
    Route::post('isvalidnumber', 'AuthController@validnumber');
   Route::post('updateuser', 'AuthController@updateuser');
     Route::post('insertprofilepicture','InsertPPictureController@profilepicture');

});

所有页面工作正常只有这个页面不起作用

Route::post('insertprofilepicture','InsertPPictureController@profilepicture');

Answer 1

由于控制器代码中的以下行，您收到404错误：

$user = User::findOrFail($request->id);

您提供的id不存在于您的用户表中，因为您没有捕获异常，因此Laravel返回404响应，实际上是ModelNotFoundException

参考here

转到上面链接的“未找到例外”部分。以下是doc中的一些行：

If the exception is not caught, a 404 HTTP response is automatically sent back to the user

Answer 2

echo '<pre>'.print_r($user,1);die(); 

只需在$ user = User :: findOrFail（$ request-> id）之后输入这一行;线。我建议你检查数据数组传递给这个控制器。如果它是通过，逐行后你可以检查。
