Why's my controller giving me a failed response via my endpoint? - php

Question

I'm trying to make a POST request with params in terms of a file upload and user text upon user clicking Submit. However, I keep getting a failed response via the dd(); (which's coming from the API endpoint I've received) for some reason even though I get the file upload success message defined by the flash. What am I doing wrong in my controller?
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Zttp\Zttp;
class FileUploadController extends Controller {
public function index(){
return view('view/index');
}
public function uploadFile(Request $request) {
$userText = $request->input('userText'); // grabbing text area input that user inputs
if ($request->input('submit') != null ){
$file = $request->file('file'); // file user wants to upload
// File Details
$filename = $file->getClientOriginalName();
$extension = $file->getClientOriginalExtension();
$fileSize = $file->getSize();
// Valid File Extensions
$valid_extension = ["jpg", "jpeg", "png", "bmp"];
// 10MB in Bytes
$maxFileSize = 10485760;
// Check file extension
if(in_array(strtolower($extension),$valid_extension)) {
// Check file size
if($fileSize <= $maxFileSize){
$request->session()->flash('message','Upload Successful.');
$response = Zttp::post("https://myendpoint.com/upload.php", [
'one' => 'some text',
'two', 'some other text',
'three' => $filename,
'four' => $userText
]);
$responseJson = $response->json(); // parses json response into an array for you
dd($responseJson);
} else {
$request->session()->flash('message','File too large. File must be less than 2MB.');
}
} else {
$request->session()->flash('message','Invalid File Extension.');
}
}
// Redirect to index
return redirect()->action('FileUploadController#index');
}
}

The question is a bit of a red herring. It's not your controller giving the failed response. Whatever's going on at the endpoint is living in a seperate request and the error lives there.
Additionally – your flash message declares the upload successful before your controller posts anything to your endpoint.
<?php
// ...
$request->session()->flash('message','Upload Successful.');
$response = Zttp::post("https://myendpoint.com/upload.php", [/* */]);
I reccommend you parse the $response more thoroughly and only set the flash message if the response code is 2XX.
Any debugging re: a failed response at that endpoint will rely on more info, including the response itself, and the nature of the endpoint. (Is it also yours? A third party API?)
