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。
复制代码 代码如下:
<?php /**
* 使用PHP Socket 编程模拟Http post和get请求
* @author koma
*/ class Http{
private $sp = “\r\n”; //这里必须要写成双引号private $protocol = ‘HTTP/1.1’;
private $requestLine = “”;
private $requestHeader = “”;
private $requestBody = “”;
private $requestInfo = “”;
private $fp = null;
private $urlinfo = null;
private $header = array();
private $body = “”;
private $responseInfo = “”;
private static $http = null; //Http对象单例
private function __construct() {}
public static function create() {
if ( self::$http === null ) {
self::$http = new Http();
}
return self::$http;
}
public function init($url) {
$this->parseurl($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””
* 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 = “/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：
复制代码 代码如下:
