I am currently building a Financial micro service application using Laravel/Lumen micro framework.Everything have been working perfectly as expected. My problem now is that i am trying to make a network request to my internal services via Api call from ApiGateway
using GuzzleHttp
client. The problem is that when i make request to the internal service, it always throws an exception of ClientException.
ClientException.
Client error:
GET http://127.0.0.1:8081/v1/admin
resulted in a401 Unauthorized
response: {"error":"Unauthorized.","code":401}
I have tried to make network request to the same internal services using postman; and it works fine. However, for some reason still fail to work with GuzzleHttp
. I don't know what i am doing wrong. Please your assist will be appreciated.
Here is the httpClient.php in ApiGateway.
//Constructor method
public function __construct() {
$this->baseUri = config('services.auth_admin.base_uri');
}
public function httpRequest($method, $requestUrl, $formParams = [], $headers = []) {
//Instantiate the GazzleHttp Client
$client = new Client([
'base_uri' => $this->baseUri,
]);
//Send the request
$response = $client->request($method, $requestUrl, ['form_params' => $formParams, 'headers' => $headers]);
//Return a response
return $response->getBody();
}
//Internal Service Communication in ApiGateway**
public function getAdmin($header) {
return $this->httpRequest('GET', 'admin', $header);
}
InternalServiceController.php
public function getAdmin(Request $request) {
return $this->successResponse($this->authAdminService->getAdmin($request->header()));
}
I am using Lumen version: 5.8 and GuzzleHttp Version: 6.3
You pass your headers as formParams (third index instead of fourth).
Try below:
return $this->httpRequest('GET', 'admin', [], $header);
