如何在Lumen中自定义错误的JSON格式(Laravel)

问题描述：

如果从数据库获取数据时出现错误或任何其他问题，我将发送这样的错误消息:

I am sending error messages like this in case of errors in getting data from DB or any other issue:

return response()->json(['status' => 'Failed' ,'state'=>'100' , 'message'=>'You have not registered yet.' ], 401);

这为我提供了一个定义了所有内容的JSON，因此无论出现什么问题，我都可以轻松显示该消息.

This gives me a JSON which has everything defined so I easily show the message whatever the problem is.

但是如果在验证时出错，我似乎没有权力更改错误响应JSON的格式.

But in case of error in case of validation, I don't seem to have the power to change the format of the error response JSON.

   $this->validate($request, [
    'email' => 'required',
    'password' => 'required'
    ]);

我想自定义错误格式为上面给出的格式，这样我就不必更改错误显示机制.

I want to customize the error format as the one given above so that I don't have to change my error showing mechanism.

答

您可以手动创建验证器，并在失败时添加自定义响应，如下所示:

You can manually create a validator and add your custom response if it fails, like this:

$validator = Validator::make($request->all(), [
    'email' => 'required',
    'password' => 'required'
]);

if ($validator->fails()) {
    return response()->json(['status' => 'Failed' ,'state'=>'100' , 'message'=> $validator->errors()->first() ], 401);
}
