Question

Laravel 5.5

public function register(Request $request){


    request()->validate([
        'email' => 'required:email'
        'password' => 'required|min:6'
    ]);

    return response()->json(["message" => "Hello World"]);

}

如果验证程序失败，则不会给出错误消息。重定向主页

Answer 1

如果您使用的代码在验证失败时将您重定向到上一页，则表示您没有告诉服务器您希望接收哪种响应。

设置合适的标头以获取JSON。它将使验证器发送JSON作为响应。例如：

$.ajax({
  headers: {
    Accept : "application/json"
  },
  ...
});

然后此代码将按预期工作：

public function register(Request $request) 
{
    $request->validate([
        'email' => 'required:email'
        'password' => 'required|min:6'
    ]);

    return response()->json(["message" => "Hello World"]);
}

Answer 2

你可以这样做：

$validator = Validator::make($request->all(), [
    'email' => 'required|email', //use pipe here to apply multiple validations rules and add a ','
    'password' => 'required|min:6'
]);

if ($validator->fails()) {
    return response()->json(['errors' => $validator->errors()]);
}
return response()->json(["message" => "Hello World"]);

Answer 3

验证效果很好，但是，$ request-＆gt; validate（）会将您重定向到上一页。我建议您手动创建验证： Manually Creating Validations。你可以这样做：

use Illuminate\Http\Request;
use Validator;
class YourClass extends Controller{
    public function yourFunction(Request $request){
        $validator = Validator::make($request->all(),[
            'field_1' => 'rule1|rule2',
            'field_2' => 'rule1|rule2'
        ]);

        if($validator->fails()){
            return response()->json($validator->errors());
        }else{
            /*Something else*/
        }
    }
}

我在Postman应用程序中测试我的rest api时遇到了同样的问题。

如果我们不想修改我们当前的laravel redirect repose代码，我们必须把Accept：-application / json和ContentType：-application / json

为了修改控制器类文件中的代码，我这样做了，得到了json响应，而不是重定向到主页。

 public function register(Request $request)
    {
      $validator = Validator::make($request->all(), [
        'name' => 'required|string|max:255',
        'email' => 'required|string|email|max:255|unique:users',
        'password' => 'required|string|min:6',
        ]);

       if ($validator->fails()) {
          return response()->json($validator->errors());
        }else{
           //do something
       }
  }

在下面的代码看起来像是重定向到主页

这是验证器功能

protected function validator(array $data)
    {
        return Validator::make($data, [
            'name' => 'required|string|max:255',
            'email' => 'required|string|email|max:255|unique:users',
            'password' => 'required|string|min:6',
        ]);
    }
public function register(Request $request)
{

    // Here the request is validated. The validator method is located
    // inside the RegisterController, and makes sure the name, email
    // password and password_confirmation fields are required.
    $this->validator($request->all())->validate();

    // A Registered event is created and will trigger any relevant
    // observers, such as sending a confirmation email or any 
    // code that needs to be run as soon as the user is created.
    event(new Registered($user = $this->create($request->all())));

    // After the user is created, he's logged in.
    $this->guard()->login($user);

    // And finally this is the hook that we want. If there is no
    // registered() method or it returns null, redirect him to
    // some other URL. In our case, we just need to implement
    // that method to return the correct response.
    return $this->registered($request, $user)
                    ?: redirect($this->redirectPath());
}

试试这个，希望这段代码可以帮到你

$this->validate($request, [
        'email'    => 'required|email',
        'password' => 'required|min:6'
    ]);
