Github API在获取用户信息时返回NULL响应

I am integrating GitHub API in my CakePhp project. I am using cURL for making request. I am able to get oAuth Code and AccessToken successfully.

But when I am trying to fetch User information by calling

https:\api.github.com\user?access_token=7190aa11e267e0665edd367ab723d18ec34c7d64

I am getting null response.

I am pasting the response that I got below:

headers":{"url":"https://api.github.com/user?access_token=7190aa11e267e0665edd367ab723d18ec34c7d64","content_type":null,"http_code":0,"header_size":0,"request_size":0,"filetime":-1,"ssl_verify_result":0,"redirect_count":0,"total_time":0.297,"namelookup_time":0.047,"connect_time":0.297,"pretransfer_time":0,"size_upload":0,"size_download":0,"speed_download":0,"speed_upload":0,"download_content_length":-1,"upload_content_length":-1,"starttransfer_time":0,"redirect_time":0},"**response":null}

Please let me know what am I missing?

Posting answer to the question I raised above.

Problem was with cURL SSL verification. So I turned it off. >curl_setopt( $c, CURLOPT_SSL_VERIFYPEER, false ); Please let me know if there is a better solution.
