以JSON格式返回验证错误消息-Laravel 6 [英] Return validation error message as JSON - Laravel 6

问题描述

我想以JSON返回失败的验证尝试消息.我以前使用过类似的东西，我认为它正在Laravel 5上工作.

I want to return a failed validation attempt message in JSON. I used something like this before, which was working on Laravel 5, I believe...

if ($validator->fails()) {    
    return response()->json($validator->messages(), 200);
}

但是，对于我们的新项目，我们使用的是Laravel 6，上面的代码只是返回一个空白页.

However, for our new project we are using Laravel 6 and the above just returns a blank page.

在Laravel 6中，以下内容成功返回了错误消息，尽管不是JSON ...

In Laravel 6 the following returns the error message successfully, albeit not in JSON...

if ($validator->fails()) {  
    $msg = $validator->messages();
    dd($msg);
}

在Laravel 6中， response()的工作方式必须有所改变.

There must be a change in the way response() works in Laravel 6.

有什么想法可以使Laravel 6中的JSON中返回验证消息吗?谢谢.

Any ideas how I get the Validation messages to get returned in JSON in Laravel 6? Thanks.

推荐答案

在这里，

if($validatedData->fails()){
   return response()->json([
      'status'   => 'error',
      'message'  => $validatedData->getMessageBag()
   ],400);
}

您可以在JSON中捕获这些错误，这是示例代码

You can grab these errors in JSON, This is sample code

 $.ajax({
    url: "{{ route('your_route_name') }}",
    method: 'post',
    cache: false,
    contentType: false,
    processData: false,
    data: formData,
    success: function(response){
        //....YOUR SUCCESS CODE HERE
    },
    error: function(response){
        // HERE YOU CAN GET ALL THE ERRORS IN JSON
        var data = JSON.parse(response.responseText);
        if(data.message){
            if(data.message.f_name){
                $('input[name=f_name]')
                .parents('.form-group')
                .find('.help-block')
                .html(data.message.f_name)
                .css('display','block');
            }else{
                $('input[name=f_name]')
                .parents('.form-group')
                .find('.help-block')
                .html('')
                .css('display','none');
            }
        }else{
            $('.help-block').html('').css('display','none');
        }
    }
});
