我进行了建议的更改，但仍然收到类似的错误：

{“error”：“invalid_request”，“error_description”：“无效的授权类型”}

如果 url 编码设置不正确，则可能会发生此错误。更新后的代码如下 任何帮助将不胜感激！

<?php

$client_id = '...';
$redirect_uri = 'http://website.com/foursquare2.php';
$client_secret = '...';
$code = $_REQUEST['code'];

$ch = curl_init();

curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));
curl_setopt($ch, CURLOPT_URL, "https://id.shoeboxed.com/oauth/token");
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_POSTFIELDS, array(
'grant_type' => 'authorization_code',
'code' => $code,
'client_id' => $client_id,
'client_secret' => $client_secret,
'redirect_uri' => $redirect_uri
));

$response = curl_exec($ch);

$err = curl_error($ch);
curl_close($ch);
if ($err) {
  echo "cURL Error #:" . $err;
} else {
  echo $response;
}
?>
