几天后我得到了授权代码，但是当我尝试通过我的测试代码将其交换为访问/刷新令牌时，我总是不断收到HTTP 400 错误。我谷歌了几天，但仍然找不到修复它的方法。有谁能帮我解决一下，谢谢。

<html>
<body>

<?php
$redirect_url = "http://.../callback_google.php";
$client_id=".....";
$client_secret=".....";
$code=$_GET['code'];
$url = 'https://accounts.google.com/o/oauth2/token?';
$postField = array ('grant_type=authorization_code',
                    'client_id='.urlencode($client_id),
                    'client_secret='.urlencode($client_secret),
                    'redirect_uri='.urlencode($redirect_url),
                    'code='.urlencode($code) );
$postField = implode('&', $postField);

$options = array(CURLOPT_URL => $url,
                 CURLOPT_HEADER => 1,
                 CURLOPT_RETURNTRANSFER => 1,
                 CURLOPT_USERAGENT => '',
                 CURLOPT_FOLLOWLOCATION => 1,
                 CURLOPT_VERBOSE => 1,
                 CURLOPT_POST => true,
                 CURLOPT_POSTFIELDS => http_build_query($postField) );

$ch = curl_init();
curl_setopt_array($ch, $options);
$result = curl_exec($ch);
curl_close($ch);
print '<pre>' . print_r($result, true) . '</pre>';
?>

</body>
</html>

但我收到错误消息

JSON响应是

{
  "error" : "invalid_request"
}

任何人都可以帮助我解决它，谢谢。

（评论中回答的问题。转换为社区 wiki 答案。请参阅没有答案的问题，但问题在评论中已解决（或在聊天中扩展））

OP写道：

此问题已修复，它是由数组和http_build_query. 更改为： $postField = 'grant_type=authorization_code&client_id='.urlencode($client_id). &client_secret='.urlencode($client_secret).'&redirect_uri='.urlencode($redirect_‌​url).'code='.urlencode($code);，并删除函数调用http_build_query。
