如何在curl调用中访问优步API OAuth 2.0载体令牌

我从Uber API获取一个访问令牌，它作为以下代码的json输出返回。我面临的问题是我只需要访问令牌存储在变量中，我需要通过我的其他API调用。如何在curl调用中访问优步API OAuth 2.0载体令牌

我的代码：

<?php 
    $fields_string = ''; 
    $fields = array(
     'client_secret' => 'xxxxxxxxxxx', 
     'client_id' => 'xxxxxxxxxx', 
     'grant_type' => 'authorization_code', 
     'redirect_uri' => "xxxxxxxxx", 
     'code' => $_GET['code'] 
    ); 
    foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; } 
    rtrim($fields_string, '&'); 
    $ch = curl_init(); 
    curl_setopt($ch,CURLOPT_URL, "https://login.uber.com/oauth/v2/token"); 
    curl_setopt($ch,CURLOPT_POST, count($fields)); 
    curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string); 

    $result = curl_exec($ch); 
    $responseData = json_decode($result , TRUE); 
    $access_token = $responseData["access_token"]; 
    echo "Access Token :" . $access_token ; 
    curl_close($ch); 
?>

输出：

{"last_authenticated":0,"access_token":"QW.eyJ2FD6546754GGF6IktmczloQWo2VDJpb1gwWHVjUWVTdEE9PSIsImV4cGlyZXNfYXQiOjE0OTc5NDgwMTksInBpcGVsaW5lX2tleV9pZCI6Ik1RPT0iLCJwaXBlbGluZV9pZCI6MX0.v95QyTqyK0PPEpG1MlBtYq8-hYU44TX#GFGFGFGEUuFI","expires_in":2592000,"token_type":"Bearer","scope":"history history_lite places profile ride_widgets","refresh_token":"#$HGHG.CAESEBhoHMvuTUNUu3QXwd9hJ_kiATEoATIBMQ.aqfiFhkCA21MCOmhf92kqj_pIlMNcyKHMQ-2fImMdWI.w_s3tB3xnxpq826UXUtUsmuneDh1bvcEfdfdvC5JXU"}Access Token :

我可以看到访问令牌的JSON响应产生的，但我无法将其存储在一个变量。

我需要通过访问令牌在下面其他卷曲电话：

$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL, "https://api.uber.com/v1.2/history"); 
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Authorization', 'OAuth '+$atoken)); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($ch, CURLOPT_POST, 1); 
$curl_response = curl_exec($ch); 
print_r($curl_response); 
curl_close($ch);

你缺少这一点，你需要添加此CURLOPT_RETURNTRANSFER选项，如果不将此那么你$result将导致空值。

curl_setopt($ch,CURLOPT_RETURNTRANSFER, true);

所以你的整个代码会是这样

$ch = curl_init(); 
curl_setopt($ch,CURLOPT_URL, "https://login.uber.com/oauth/v2/token"); 
curl_setopt($ch,CURLOPT_POST, count($fields)); 
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string); 

curl_setopt($ch,CURLOPT_RETURNTRANSFER, true);//add this to your code. 

$result = curl_exec($ch); 
$responseData = json_decode($result , TRUE); 
$access_token = $responseData["access_token"]; 
echo "Access Token :" . $access_token ; 
curl_close($ch);
