这里给大家分享一段使用PHP Socket 编程模拟Http post和get请求的代码，非常的实用，结尾部分我们再讨论下php模拟http请求的几种方法。
parseurl($url); $this->header['Host'] = $this->urlinfo['host']; return $this; } public function get($header = array()) { $this->header = array_merge($this->header, $header); return $this->request('GET'); } public function post($header = array(), $body = array()) { $this->header = array_merge($this->header, $header); if ( !empty($body) ) { $this->body = http_build_query($body); $this->header['Content-Type'] = 'application/x-www-form-urlencoded'; $this->header['Content-Length'] = strlen($this->body); } return $this->request('POST'); } private function request($method) { $header = ""; $this->requestLine = $method.' '.$this->urlinfo['path'].'?'.$this->urlinfo['query'].' '.$this->protocol; foreach ( $this->header as $key => $value ) { $header .= $header == "" ? $key.':'.$value : $this->sp.$key.':'.$value; } $this->requestHeader = $header.$this->sp.$this->sp; $this->requestInfo = $this->requestLine.$this->sp.$this->requestHeader; if ( $this->body != "" ) { $this->requestInfo .= $this->body; } /* * 注意：这里的fsockopen中的url参数形式为"www.xxx.com" * 不能够带"http://"这种 */ $port = isset($this->urlinfo['port']) ? isset($this->urlinfo['port']) : '80'; $this->fp = fsockopen($this->urlinfo['host'], $port, $errno, $errstr); if ( !$this->fp ) { echo $errstr.'('.$errno.')'; return false; } if ( fwrite($this->fp, $this->requestInfo) ) { $str = ""; while ( !feof($this->fp) ) { $str .= fread($this->fp, 1024); } $this->responseInfo = $str; } fclose($this->fp); return $this->responseInfo; } private function parseurl($url) { $this->urlinfo = parse_url($url); } } // $url = "http://news.163.com/14/1102/01/AA0PFA7Q00014AED.html"; $url = "http://localhost/httppro/post.php"; $http = Http::create()->init($url); /* 发送get请求 echo $http->get(array( 'User-Agent' => 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.153 Safari/537.36', )); *//* 发送post请求 */ echo $http->post(array( 'User-Agent' => 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.153 Safari/537.36', ), array('username'=>'发一个中文', 'age'=>22)); php 模拟 http请求
方法一：利用php的socket编程来直接给接口发送数据来模拟post的操作。
建立两个文件post.php,getpost.php
post.php内容如下： 'abc', 'var2'=>'how are you , my friend??');//构造要post的字符串foreach ($argv as $key=>$value) { if ($flag!=0) { $params .= "&"; $flag = 1; } $params.= $key."="; $params.= urlencode($value); $flag = 1; } $length = strlen($params); //创建socket连接 $fp = fsockopen("localhost",81,$errno,$errstr,10) or exit($errstr."--->".$errno); //构造post请求的头 $header = "POST /flandy/getpost.php HTTP/1.1\r\n"; $header .= "Host:127.0.0.1\r\n"; $header .= "Referer:/flandy/post.php\r\n"; $header .= "Content-Type: application/x-www-form-urlencoded\r\n"; $header .= "Content-Length: ".$length."\r\n"; $header .= "Connection: Close\r\n\r\n"; //添加post的字符串 $header .= $params."\r\n"; //发送post的数据 fputs($fp,$header); $inheader = 1; while (!feof($fp)) { $line = fgets($fp,1024); //去除请求包的头只显示页面的返回数据 if ($inheader && ($line == "\n" || $line == "\r\n")) { $inheader = 0; } if ($inheader == 0) { echo $line; } } fclose($fp);?> getpost.php的内容如下：
";print_r($_REQUEST);echo "";?>
结果输出：
this is the data postedArray([var1] => abc[var2] => how are you , my friend??)
以上代码在本机81端口下已经通过测试。
方法二：使用PHP的curl扩展或HttpClient.class.php类，这两个非常类似，下面简单的列出curl的实现代码。
两个文件post2.php和getpost2.php post2.php的内容如下：getpost2.php的内容如下：
";echo "";print_r($_REQUEST);echo "";?>
结果输出：
Array ( [0] => returndataArray([web] => 'wwwbaiducom'[pwd] => 123456[action] => check[pseid] => 'NDE005'[amt] => 1))
方法三：这个要借助第三方类库HttpClient可以到这里下载：
＜?phprequire_once 'HttpClient.class.php';$params = array('web' =＞ 'www.baidu.com','pwd' =＞ '123456','action' =＞ 'check','pseid' =＞ 'NDE005','amt' =＞ 1);$pageContents = HttpClient::quickPost('http://localhost:81/flandy/getpost3.php', $params);$result = explode(',', $pageContents);print_r($result);?＞
