PHP: Guzzle Client - Proxy request to different server - php

Question

So, I am just trying to proxy all requests to a different server.
I want everything to be the same, except I want to change the base uri.
<?php
namespace App\MicroServices\Example\Clients;
use GuzzleHttp\Client;
use Illuminate\Http\Request;
/**
* Class ExampleClient
* #package App\MicroServices\Example\Clients
*/
class ExampleClient extends Client implements ClientInterface
{
/**
* ExampleClient constructor.
*/
public function __construct()
{
parent::__construct([
'base_uri' => config('example.base.uri'),
'timeout' => config('example.client.timeout'),
]);
}
/**
* #param Request $request
*
* #return string
*
* #throws \GuzzleHttp\Exception\GuzzleException
*/
public function proxyToExampleServer(Request $request)
{
$method = $request->getMethod();
$body = json_decode($request->getContent(), true);
$path = $request->path() . ($request->getQueryString() ? ('?' . $request->getQueryString()) : '');
$headers = [];
foreach ($request->header() as $key => $value)
{
$headers[$key] = $value[0];
}
$headers['Authorization'] = $request->bearerToken();
return $this->request($method, $path, ['headers' => $headers, 'body' => $body])->getBody()->getContents();
}
}
Response in Postman is 400 Bad Request, I have tried changing to 'form_params' and 'json'
Any thoughts?

Answer 1

So, I got it working with this function
/**
* #param Request $request
*
* #return string
*
* #throws \GuzzleHttp\Exception\GuzzleException
*/
public function proxyToExampleServer(Request $request)
{
$method = $request->getMethod();
$body = json_decode($request->getContent(), true);
$path = $request->path() . ($request->getQueryString() ? ('?' . $request->getQueryString()) : '');
$headers = $request->header();
try {
return $this->request($method, $path, ['headers' => $headers, 'json' => $body])->getBody()->getContents();
} catch (ClientException $exception) {
return $exception->getResponse();
}
}
