Question

我将验证器用作

   $validator = Validator::make($request->all(), [
        'name' => 'required|max:255',
        'phone' => 'required|max:10|unique:users',
        'email' => 'required|email|max:255|unique:users',
        'password' => 'required|min:6',
    ]);

    if ($validator->fails()) {
        return response()->json(['error'=>$validator->errors()], 401);            
    }

这将以以下格式给出响应：

 {
    "error": {
        "phone": [
            "The phone has already been taken."
        ],
        "email": [
            "The email has already been taken."
        ]
    }
}

我希望回复

{
"error": 1,
"error_msg": "The phone has already been taken."
}

只有一种错误应该以上述格式显示。

为使验证在第一次验证失败后停止，laravel使用bail检查this。因此规则将是这样

$validator = Validator::make($request->all(), [
    'name' => 'bail|required|max:255',
    'phone' => 'bail|required|max:10|unique:users',
    'email' => 'bail|required|email|max:255|unique:users',
    'password' => 'required|min:6',
]);

对于格式化错误消息，您需要在响应中进行一些更改

if ($validator->fails()) {
    return response()->json(['error'=> 1, 'error_msg' => $validator->errors()->first()], 400);           
}

您可以创建一个中心位置来呈现验证错误，以使其在整个应用程序中保持一致的验证响应格式。

希望这可能对您有帮助

使用Form Request进行验证：

class CreateUserRequest extends FormRequest {
     public function authorize()
     {
         return true;
     }

     public function rules()
     {
         return [
            'name' => 'required|max:255',
            'phone' => 'required|max:10|unique:users',
            'email' => 'required|email|max:255|unique:users',
            'password' => 'required|min:6',
         ];
     }

     public function messages()
     {
         return [
            'phone.unique' => 'The phone has already been taken.',
            'email.unique'  => 'The email has already been taken.',
         ];
     }
}

然后在您的控制器中使用它：

public function create(CreateUserRequest $request)
{
     $user = User::create($request->all());

     return response()->json(['user'=>$user]);
}

这会在运行create方法之前进行验证，并在json响应中为您返回验证错误消息。

我建议不要更改响应的格式，而应适应laravel返回的格式，因为它始终是统一的形状。这样，您的客户可以期望一致的api响应。

此外，验证失败应该是422状态，而不是用于身份验证的401。

在laravel中以自定义格式返回验证器响应？
