php如何在curl获取请求标头中使用承载令牌？

下面是一个有效的 C# get 请求

public HttpResponseMessage ExecuteEndPoint(string endpoint,string accessTocken) {
            HttpResponseMessage responseMessage = new HttpResponseMessage();
            using (var client = new HttpClient())
            {
                client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", accessTocken);
                responseMessage = client.GetAsync(endpoint).Result;
            }
            return responseMessage;
        }

我想使用curl在php中执行相同的请求，下面是我尝试过的

$request_headers=array();
     $request_headers[]='Bearer: '.$access_token;
    //$request_headers[]='Content-Length:150';
    $handle1=curl_init();
    $api_url='here my api get url';


    curl_setopt_array(
        $handle1,
        array(
                CURLOPT_URL=>$api_url,
                CURLOPT_POST=>false,
                CURLOPT_RETURNTRANSFER=>true,
                CURLOPT_HTTPHEADER=>$request_headers,
                CURLOPT_SSL_VERIFYPEER=>false,
                CURLOPT_HEADER=>true,
                CURLOPT_TIMEOUT=>-1
        )
    );

    $data=curl_exec($handle1);
    echo serialize($data);

看起来 api 没有收到 access_token。 任何帮助表示赞赏。 谢谢

您还需要指定“授权”...

curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    "Authorization: Bearer ".$access_token
));
