How to add headers in Guzzle http
提问by rajesh
I'm building a small application in Laravel 5.5where I'm using Guzzle Httpto get call the api url and get the response, Few of the api calls have certain condition to have headers which works as authorization of the request generated. I'm trying to place the header something like this:
我正在构建一个小型应用程序，在Laravel 5.5其中我Guzzle Http用来调用 api url 并获得响应，很少有 api 调用具有某些条件来具有作为生成请求的授权的标头。我正在尝试放置这样的标题：
public function post(Request $request)
{
try {
if ($request->url_method == 'get') {
$request = $this->client->get($request->url, [ 'headers' => [ 'access_token' => $request->headers->access_token]]);
}
else if ($request->url_method == 'post')
{ $request = $this->client->post($request->url, [$request->request_data]); }
else { return response()->json(['data' => 'Invalid Method'],500); }
$response = \GuzzleHttp\json_decode($request->getBody());
return response()->json(['data' => json_decode($response->d)], $request->getStatusCode());
}
catch (ClientException $e) {
return response()->json(['data' => 'Invalid Request.'], $request->getStatusCode());
}
}
But this is giving me errors:
但这给了我错误：
Undefined property: Symfony\Component\HttpFoundation\HeaderBag::$access_token
未定义的属性：Symfony\Component\HttpFoundation\HeaderBag::$access_token
Please checkout the screenshot:

'headers' => $headers
]);
$body = '{
"key1" : '.$value1.',
"key2" : '.$value2.',
}';
$r = $client->request('POST', 'http://example.com/api/postCall', [
'body' => $body
]);
$response = $r->getBody()->getContents();

Try to add bearer in all small cases before access token like following -
尝试在访问令牌之前在所有小情况下添加承载，如下所示 -
$access_token = 'bearer '.$request->headers->access_token
