######附二：CURL请求方法
/** * CURL请求 * @param $url 请求url地址 * @param $method 请求方法 get post * @param null $postfields post数据数组 * @param array $headers 请求header信息 * @param bool|false $debug 调试开启 默认false * @return mixed */ function httpRequest($url, $method, $postfields = null, $headers = array(), $debug = false) { $method = strtoupper($method); $ci = curl_init(); /* Curl settings */ curl_setopt($ci, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_0); curl_setopt($ci, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.2; WOW64; rv:34.0) Gecko/20100101 Firefox/34.0"); curl_setopt($ci, CURLOPT_CONNECTTIMEOUT, 60); /* 在发起连接前等待的时间，如果设置为0，则无限等待 */ curl_setopt($ci, CURLOPT_TIMEOUT, 7); /* 设置cURL允许执行的最长秒数 */ curl_setopt($ci, CURLOPT_RETURNTRANSFER, true); switch ($method) { case "POST": curl_setopt($ci, CURLOPT_POST, true); if (!empty($postfields)) { $tmpdatastr = is_array($postfields) ? http_build_query($postfields) : $postfields; curl_setopt($ci, CURLOPT_POSTFIELDS, $tmpdatastr); } break; default: curl_setopt($ci, CURLOPT_CUSTOMREQUEST, $method); /* //设置请求方式 */ break; } $ssl = preg_match('/^https:\/\//i',$url) ?
