接入第三方QQ登录提示未开启curl [ 2.0 版本 ]

建议你写个请求方法，写到一个公共文件里，以后那个接口要用到都可以调用！
1.这个是请求参数为json格式的时候：

/**
 * post方式请求接口信息（参数json）
 * @param  [type] $url         [description]
 * @param  [type] $data_string [description]
 * @return [type]              [description]
 */
public static function http_post($url, $data_string) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(
        'X-AjaxPro-Method:ShowList',
        'Content-Type: application/json; charset=utf-8',
        'Content-Length: ' . strlen($data_string))
    );
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
    $data = curl_exec($ch);
    curl_close($ch);
    return $data;
}
2.普通post发送请求
public static function SendByCurl($url, $param){
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_TIMEOUT, 10);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $param);
    ob_start();
    curl_exec($ch);
    $result = ob_get_contents();
    ob_end_clean();
    curl_close($ch);
    return $result;
}
3.get方式
    public static function getCurl($url){
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
    curl_setopt($ch, CURLOPT_TIMEOUT, 15);
    $result = curl_exec($ch);
    if (!$result) {
        //输出错误信息
        //trigger_error(curl_error($ch));
        return false;
    }
    curl_close($ch);
    return $result;
}
