302 redirect when using Laravel's Form Request Validation

[karlpatrickespiritu]

Whenever I typehint a request validation in controller function like so:

/**
 * Store a newly created resource in storage.
*
 * @param StoreStaffEventLog|Request $request
* @return \Illuminate\Http\Response
 */
public function store(StoreStaffEventLog $request)
{
    if (!$this->eventStaffRepository->find($request->staff_event_id)) return $this->respondBadRequest();

    $this->eventStaffLogRepository->create([
         'staff_event_id' => $request->staff_event_id,
         'type' => $request->type,
    ]);

     return $this->respondCreated();
}

I'll get a 302 response redirect. See JS response below:

XMLHttpRequest cannot load http://company-site.com/api/1.0/staff/logs. Redirect from
'http://company-site.com/api/1.0/staff/logs' to 'http://localhost:8100/' has been blocked 
by CORS policy: Request requires preflight, which is disallowed to follow cross-origin redirect.

But if I replace the StoreStaffEventLog $request to Request $request. My request works fine and returns me a 201 Created status code.

Closing this as part of an issue-cleanup. Please re-open if this is still an issue on the latest version.

I have the same issue, running 5.5.28

[simplyrupin]

Yes, agree with @NoelDavies the issue has returned when using Laravel 5.5.28

laravel 5.5
i put the the request header solve the problem.
'X-Requested-With': 'XMLHttpRequest'

laravel will return json when found this header.

actual, there are two method return json.
in file vendor/laravel/framework/src/Illuminate/Http/Concerns/InteractsWithContentTypes.php::42
public function expectsJson() { return ($this->ajax() && ! $this->pjax()) || $this->wantsJson(); }
the ajax judges the request header whether exists X-Requested-With and equal XMLHttpRequest

Same issue persists with me today, "laravel/framework": "5.8.*"

@yunmoxue's suggestion to add a header resolved my issue

Hi
I have same issue .. I use form post not ajax call. so where i add X-Requested-With?

[amadoutidiane]

i need to know where put it @yunmoxue or @CharJ 'X-Requested-With': 'XMLHttpRequest'

[yunmoxue]

@lbrevity @amadoutidiane you can add request header when you use xhr.
there is api.

[amadoutidiane]

@yunmoxue and @CharJ i'am new ate dev and i need you write all the code of ajax request and tell who i exactly put 'X-Requested-With': 'XMLHttpRequest' in the code thx for help

[S33G]

An example of adding the header to a jQuery Ajax for @amadoutidiane.

Thought I'd share the solution for others here 🙂

$.ajax({
  type: "POST",
  beforeSend: function(request) {
    request.setRequestHeader("X-Requested-With", "XMLHttpRequest");
  }
});

At least in Laravel 6.0, setting a request header of Accept: application/json will also trigger a JSON response (without needing to set the X-Requested-With header).

This solves the problem for me:
Insert Accept: application/json in ajax header

$.ajax({
url:'{{route('fetchMunCit')}}' +'/'+id,
type:'GET',
dataType:'json',
Accept: application/json
success:function(response)

Adding Accept: application/json did not solve it for me
