发送Get请求:

private function httpGet($url) {    $curl = curl_init();    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);    curl_setopt($curl, CURLOPT_TIMEOUT, 500);    // 为保证第三方服务器与微信服务器之间数据传输的安全性,所有微信接口采用https方式调用,必须使用下面2行代码打开ssl安全校验。    // 如果在部署过程中代码在此处验证失败,请到 http://curl.haxx.se/ca/cacert.pem 下载新的证书判别文件。    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, true);    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, true);    curl_setopt($curl, CURLOPT_URL, $url);    $res = curl_exec($curl);    curl_close($curl);    return $res;  }


发送Post请求:

/**  * 发送post请求  * @param string $url 请求地址  * @param array $post_data post键值对数据  * @return string  */  function send_post($url, $post_data) {      $postdata = http_build_query($post_data);    $options = array(      'http' => array(        'method' => 'POST',        'header' => 'Content-type:application/x-www-form-urlencoded',        'content' => $postdata,        'timeout' => 15 * 60 // 超时时间(单位:s)      )    );    $context = stream_context_create($options);    $result = file_get_contents($url, false, $context);      return $result;  }    //使用方法  $post_data = array(    'username' => 'stclair2201',    'password' => 'handan'  );  send_post('http://www.qianyunlai.com', $post_data);          <?php  /**  * Socket版本  * 使用方法:  * $post_string = "app=socket&version=beta";  * request_by_socket('chajia8.com', '/restServer.php', $post_string);  */  function request_by_socket($remote_server,$remote_path,$post_string,$port = 80,$timeout = 30) {    $socket = fsockopen($remote_server, $port, $errno, $errstr, $timeout);    if (!$socket) die("$errstr($errno)");    fwrite($socket, "POST $remote_path HTTP/1.0");    fwrite($socket, "User-Agent: Socket Example");    fwrite($socket, "HOST: $remote_server");    fwrite($socket, "Content-type: application/x-www-form-urlencoded");    fwrite($socket, "Content-length: " .
