我使用的是来自FiWare.org的KeyRock。以前一切似乎都可以找到，但现在在用户授权后的其余服务器向我发送以下响应。我看过服务器的响应，它似乎是一个空/空的响应。但是在NodeJS上，请求被无缝地处理。我正在使用wp-oauth插件，并将其修改为与FiWare一起使用。我通过PHP CURL发送此请求。FiWare WP-OAuth用户认证PHP CURL
{
"error": {
"message": "Expecting to find application/json in Content-Type header - the server could not comply with the request since it is either malformed or otherwise incorrect. The client is assumed to be in error.",
"code": 400,
"title": "Bad Request"
}
}
以下是卷曲要求我使用：
$url = URL_TOKEN . $url_params;
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, $params);
curl_setopt($curl, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
curl_setopt($curl, CURLOPT_USERPWD, CLIENT_ID . ":" . CLIENT_SECRET);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, (get_option('wpoa_http_util_verify_ssl') == 1 ? 1 : 0));
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, (get_option('wpoa_http_util_verify_ssl') == 1 ? 2 : 0));
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($curl);
