PHP封装curl的调用接口及常用函数的介绍

如下所示：

 ?php * @desc 封装curl的调用接口，post的请求方式 function doCurlPostRequest($url, $requestString, $timeout = 5) {  if($url == || $requestString == || $timeout = 0){ return false; $con = curl_init((string)$url); curl_setopt($con, CURLOPT_HEADER, false); curl_setopt($con, CURLOPT_POSTFIELDS, $requestString); curl_setopt($con, CURLOPT_POST, true); curl_setopt($con, CURLOPT_RETURNTRANSFER,true); curl_setopt($con, CURLOPT_TIMEOUT, (int)$timeout); curl_setopt($con, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($con, CURLOPT_SSL_VERIFYHOST, false); return curl_exec($con); * @desc 封装curl的调用接口，post的请求方式 function doCurlPostsslRequest($url, $requestString,$pemfile, $timeout = 5) {  if($url == || $requestString == || $timeout = 0){ return false; echo $pemfile; $con = curl_init((string)$url); curl_setopt($con, CURLOPT_HEADER, false); curl_setopt($con, CURLOPT_POSTFIELDS, $requestString); curl_setopt($con, CURLOPT_POST, true); curl_setopt($con, CURLOPT_RETURNTRANSFER,true); curl_setopt($con, CURLOPT_TIMEOUT, (int)$timeout); curl_setopt($con, CURLOPT_SSL_VERIFYPEER, 1); curl_setopt($con, CURLOPT_SSL_VERIFYHOST, 2); //curl_setopt($ch, CURLOPT_SSLCERT, $pemfile);  //curl_setopt($ch, CURLOPT_SSLCERTTYPE, PEM  curl_setopt($con, CURLOPT_CAINFO, $pemfile); return curl_exec($con); * @desc 封装curl的调用接口，post Json数据的请求方式 function doCurlPostJsonReq($url, $requestString, $timeout = 25){ if($url == || $requestString == || $timeout = 0){ return false; $con = curl_init((string)$url); curl_setopt($con, CURLOPT_HEADER, false); curl_setopt($con, CURLOPT_POSTFIELDS, $requestString); curl_setopt($con, CURLOPT_POST, true); curl_setopt($con, CURLOPT_RETURNTRANSFER,true); curl_setopt($con, CURLOPT_TIMEOUT, (int)$timeout);  curl_setopt($con, CURLOPT_HTTPHEADER, array( Content-Type: application/json , Content-Length: . strlen($data_string)) return curl_exec($con); * @desc 封装curl的调用接口，post form数据的请求方式 function doCurlPostFormReq($url, $requestString, $timeout = 25){ if($url == || $requestString == || $timeout = 0){ return false; $con = curl_init((string)$url); curl_setopt($con, CURLOPT_HEADER, false); curl_setopt($con, CURLOPT_POSTFIELDS, $requestString); curl_setopt($con, CURLOPT_POST, true); curl_setopt($con, CURLOPT_RETURNTRANSFER,true); curl_setopt($con, CURLOPT_TIMEOUT, (int)$timeout);  curl_setopt($con, CURLOPT_HTTPHEADER, array( Content-Type: application/x-www-form-urlencoded ) return curl_exec($con); * @desc 封装curl的调用接口，get的请求方式 function doCurlGetRequest($url, $data = array(), $timeout = 10) { if($url == || $timeout = 0){ return false; if($data != array()) { $url = $url . ?
