来自Dropbox API的错误HTTP“Content-Type”标头

Question

当我尝试向Dropbox API（v2）发送一个简单的curl请求时，我收到此错误：

Error in call to API function "users/get_current_account": Bad HTTP "Content-Type" header: "application/x-www-form-urlencoded". Expecting one of "application/json", "application/json; charset=utf-8", "text/plain; charset=dropbox-cors-hack".

PHP代码：

$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_POST, true);       
curl_setopt($ch, CURLOPT_URL, "https://api.dropboxapi.com/2/users/get_current_account" );
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Authorization: Bearer " . $accessToken) );
echo curl_exec($ch);
curl_close($ch);     

Answer 1

使用CURLOPT_POST选项指定内容类型（application/x-www-form-urlencoded，基于the documentation）。可以使用CURLOPT_CUSTOMREQUEST选项使其成为POST请求。

$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_URL, "https://api.dropboxapi.com/2/users/get_current_account" );
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Authorization: Bearer " . $accessToken) );
echo curl_exec($ch);
curl_close($ch);
