The laravel API interface uses Validator and cannot return specific error information that fails verification.

Validator is used in the API interface to verify the form;
When there are items that pass verification;
are all returned

<code>{
  "message": "The given data failed to pass validation.",
  "status_code": 500
}</code>

It is impossible to return specific information that has not passed verification;
When the front-end or mobile terminal receives the returned error message;
It cannot tell the user which item does not meet the requirements;
What I want is this;

<code>{
  "message": "邮箱已经注册",
  "status_code": 500
}

{
  "message": "必须是6-16位的密码",
  "status_code": 500
}</code>

Dear friends, what should I do?

Dear friends, when writing interfaces with laravel;
How are the submitted form fields verified? How to return verification results?

Laravel can customize the error format, which needs to be rewritten in the controller base class formatValidationErrors method

<code>use Illuminate\Contracts\Validation\Validator;

protected function formatValidationErrors(Validator $validator)
{
     $message = $validator->errors()->first();
     return ['message'=>$message, 'status_code' => 500];
}</code>

You can also expand it according to your own needs. The above is just a simple example, and the first error message is returned.

If you use dingo/api verification handler

Of course you can also

<code>if ($validator->fails()) {
     //自行封装个处理验证失败返回值 类似下面
     $this->respondWithValidatorError($validator->errors());    
}
</code>
