这篇文章主要介绍了关于php的http请求类,有着一定的参考价值,现在分享给大家,有需要的朋友可以参考一下

<?php namespace app\lib; class Lib_http{ //发起网络请求 public function call($url, $args = null, $method = "post", $testflag = 0, $timeout = 60, $headers = array()) {/*{{{*/ Lib_log::set_log('http',$url); $ret = false; $i = 0; while ($ret === false) { if ($i > 1) break; if ($i > 0) { sleep(1); } $ret = $this->callOnce($url, $args, $method, false, $timeout, $headers); $i++; } return $ret; }/*}}}*/ private function callOnce($url, $args = null, $method = "post", $withCookie = false, $timeout = CURL_TIMEOUT, $headers = array()) {/*{{{*/ $ch = curl_init(); if ($method == "post") { $data =$this->convert($args); curl_setopt($ch, CURLOPT_POSTFIELDS, $data); curl_setopt($ch, CURLOPT_POST, 1); } else { $data =$this->convert($args); if ($data) { if (stripos($url, "?") > 0) { $url .= "&$data"; } else { $url .= "?$data"; } } } curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_TIMEOUT, $timeout); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // curl_setopt($ch, CURLOPT_HEADER, true); if (!empty($headers)) { curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); } if ($withCookie) { curl_setopt($ch, CURLOPT_COOKIEJAR, $_COOKIE); } $r = curl_exec($ch); curl_close($ch); return $r; }/*}}}*/ private function convert(&$args) {/*{{{*/ $data = ''; if (is_array($args)) { foreach ($args as $key => $val) { if (is_array($val)) { foreach ($val as $k => $v) { $data .= $key .
