Laravel ajax 422 Unprocessable Entity even when token is matching
提问by Jakub Kohout
I'm getting 422 Unprocessable Entity error even when I'm submitting my form via Ajax.
即使我通过 Ajax 提交表单，我也会收到 422 Unprocessable Entity 错误。
My javascript file
我的 javascript 文件
$.ajaxSetup({
headers: {
'X-XSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
$('.keywords-plan-form').submit(function(event) {
event.preventDefault();
$.ajax({
url: '/laravel/public/keywordsplans',
type: 'POST',
data: $(this).serialize(),
success: function(data){
alert(data);
// success logic
},
error: function(data){
// Error...
var errors = $.parseJSON(data.responseText);
console.log(errors);
$.each(errors, function(index, value) {
});
}
});
});
as you can see I added X-XSRF-TOKEN****strong textto ajax header.
如您所见，我在 ajax 标题中添加了X-XSRF-TOKEN****strong 文本。
This is my '' tag
这是我的''标签
<meta name="csrf-token" content="{{ csrf_token() }}">
my Form Datain chrome debuger
我在 Chrome 调试器中的表单数据
_token:5j6DGhhTytbIRB1GrW9Wml9XrOxmKjgE9RiGa4Gf
date:
keyword[0]:Lorem ipsum
keyword[1]:Is dolor amet
keyword[2]:plumber tampa
Request Headers
请求头
X-XSRF-TOKEN:5j6DGhhTytbIRB1GrW9Wml9XrOxmKjgE9RiGa4Gf
.....
am I doing something wrong or forgetting something?
我做错了什么还是忘记了什么？

I don't think that csrf token is the issue here. If it were you would get TokenMissmatchException and not Unprocessable Entity. Do you happen to have a request validator in your Controller like this?
我不认为 csrf 令牌是这里的问题。如果是这样，您将获得 TokenMissmatchException 而不是 Unprocessable Entity。你碰巧在你的控制器中有一个这样的请求验证器吗？
$validator = Validator::make($request->all(), [
'username' => 'required|max:30|min:6|unique:users',
'email' => 'required|email|max:50|unique:users',
'password' => 'required|confirmed|min:6',
]);
If so maybe you can do something like this:
如果是这样，也许你可以做这样的事情：
if ($validator->fails()) {
if($request->ajax())
{
return response()->json(array(
'success' => false,
'message' => 'There are incorect values in the form!',
'errors' => $validator->getMessageBag()->toArray()
), 422);
}
$this->throwValidationException(
$request, $validator
);
}
After that you can catch validation errors in your ajax error handler like this:
之后，您可以在 ajax 错误处理程序中捕获验证错误，如下所示：
$('.keywords-plan-form').submit(function(event) {
event.preventDefault();
$.ajax({
url: '/laravel/public/keywordsplans',
type: 'POST',
data: $(this).serialize(),
success: function(data){
alert(data);
// success logic
},
error: function(jqXhr, json, errorThrown){// this are default for ajax errors
var errors = jqXhr.responseJSON;
var errorsHtml = '';
$.each(errors['errors'], function (index, value) {
errorsHtml += '<ul class="list-group"><li class="list-group-item alert alert-danger">' + value + '</li></ul>';
});
//I use SweetAlert2 for this
swal({
title: "Error " + jqXhr.status + ': ' + errorThrown,// this will output "Error 422: Unprocessable Entity"
html: errorsHtml,
width: 'auto',
confirmButtonText: 'Try again',
cancelButtonText: 'Cancel',
confirmButtonClass: 'btn',
cancelButtonClass: 'cancel-class',
showCancelButton: true,
closeOnConfirm: true,
closeOnCancel: true,
type: 'error'
}, function(isConfirm) {
if (isConfirm) {
$('#openModal').click();//this is when the form is in a modal
}
});
}
});
});
And see the messages in the modal message

I have solved this issue :
我已经解决了这个问题：
public function register(\Illuminate\Http\Request $request) {
if ($this->validator($request->all())->fails()) {
$errors = $this->validator($request->all())->errors()->getMessages();
$clientErrors = array();
foreach ($errors as $key => $value) {
$clientErrors[$key] = $value[0];
}
$response = array(
'status' => 'error',
'response_code' => 201,
'errors' => $clientErrors
);
} else {
$this->validator($request->all())->validate();
$user = $this->create($request->all());
$response = array(
'status' => 'success',
'response_code' => 200
);
}
echo json_encode($response);
}

Maybe someone will come in handy.
也许有人会派上用场。
422 Unprocessable Entity
422 无法处理的实体
is default error by validator laravel
是验证器 laravel 的默认错误
vendor/laravel/framework/src/Illuminate/Validation/Validator.php
If fails validate params, then throught Exception ValidationException
如果验证参数失败，则通过 Exception ValidationException
vendor/laravel/framework/src/Illuminate/Validation/ValidationException.php
where default status = 422
其中默认状态 = 422
And therethore all your ajax responses with non validate forms will be with status = 422
并且所有带有非验证表单的 ajax 响应都将是 status = 422
