进程休息响应php

Question

我打电话给一个站点获取访问令牌。这是响应如何使用php获取实际的令牌。

HTTP/1.1 200 OK Date: Sat, 16 Dec 2017 16:54:20 GMT 
Content-Type: application/json; 
charset=UTF-8 
Content-Length: 113 
Connection: keep-alive 
Cache-Control: no-store 
Server: Apigee Router { "access_token": "1NQA27eHVzHC6idx2f7JDbJiD4CQ", "expires_in": "3599" } 

以下代码失败。

curl_setopt($curl, CURLOPT_HTTPHEADER, array('Authorization: Basic '.$credentials)); //setting a custom header 
curl_setopt($curl, CURLOPT_HEADER, true); 
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); 

$curl_response = curl_exec($curl); 
$token = $curl_response['access_token']; 
echo "<br/>"; 
echo $token; 

Answer 1

您需要在访问值之前解码JSON。

$curl_response = curl_exec($curl); 
curl_close ($curl); 
$data = json_decode($curl_response,true); 
$token = $data['access_token']; 
echo "<br/>"; 
echo $token;
