My webapp has Laravel as backend framework which provides a Restful API and in the fronend Angularjs is running. I send different requests through the api and receive the responses and based on the code of response and data included, appropriate messages are shown to user.
Recently when I send requests using PUT method or POST method, when the data has problem in validation process and Laravel should respond with a 422 code in JSON format, instead I receive a text/html response with code 200. and then everything goes wrong.
This does not happen on my local machine, Only when I test the app in production environment this happens.
I also tested UnAuthorized response which is sent with 403 code, and it works flawlessly.
I tested both the automatic validation error for Laravel (as described in documentation: When using the validate method during an AJAX request, Laravel will not generate a redirect response. Instead, Laravel generates a JSON response containing all of the validation errors. This JSON response will be sent with a 422 HTTP status code.) and also using the following method:
return response()->json(compact('errors'),422);
I should mention that I use following methods to send AJAX requests:
function save(data, url) {
return $http({
method: 'POST',
url: url,
headers: {'Content-Type': 'application/json'},
data: angular.toJson(data)
});
}
function update(data, url) {
return $http({
method: 'PUT',
url: url + data.id,
headers: {'Content-Type': 'application/json'},
data: angular.toJson(data)
});
}
needless to say I became totally confused!
UPDATE: It seems to be a problem with Laravel validation process. when the validation runs, request become erroneous. see the following piece of code:
public function altUpdate(Request $request){
$this->authorize('editCustomer', $this->store);
if (!$request->has('customer')){
return response()->json(["message"=>"Problem in received data"],422);
}
$id = $request->customer['id'];
$rules = [
'name' => 'required',
'mobile' => "required|digits:11|unique:customers,mobile,$id,id,store_id,$this->store_id",
'phone' => 'digits_between:8,11',
'email' => "email|max:255|unique:customers,email,$id,id,store_id,$this->store_id",
];
//return response()->json(["problem in data"],422); //this one works properly if uncommented
$validator = Validator::make($request->customer,$rules);
if ($validator->fails()){
$errors = $validator->errors()->all();
Log::info($errors);
return response()->json(["problem in data"],422);//this one is received in client side as a text/html response with code 200
}
$customer = Customer::find($id);
$customer->update(wrapInputs($request->all()));
if ($request->tags) {
$this->syncTags($request->tags, $customer);
}
$message = "Customer updated successfully!";
return response()->json(compact('message'));
}
I still don't know what's the problem of validation process. this code is working on my local machine without any problems but on the production server problem occurs.
