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 /**

* @author koma

*/ class Http{

private $sp = "rn"; //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"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:

复制代码 代码如下:

<?php

$flag = 0;

$params = '';

$errno = '';

$errstr = '';

//要post的数据

$argv = array(

'var1'=>'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/1.1rn";

$header .= "Host:127.0.0.1rn";

$header .= "Referer:/flandy/post.phprn";

$header .= "Content-Type: application/x-www-form-urlencodedrn";

$header .= "Content-Length: ".$length."rn";

$header .= "Connection: Closernrn";

//添加post的字符串

$header .= $params."rn";

//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 == "rn")) {

$inheader = 0;

}

if ($inheader == 0) {

echo $line;

}

}

fclose($fp);

?>

getpost.php的内容如下

复制代码 代码如下:

<?php

echo "this is the data posted";

echo "<pre>";

print_r($_REQUEST);

echo "</pre>";

?>

结果输出:

复制代码 代码如下:

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:

复制代码 代码如下:

<?php

$psecode = 'NDE005';

$website = 'www.baidu.com';

$amt = 1;

$pwd = 123456;

$ch = curl_init();

$curl_url = "http://localhost:81/flandy/getpost2.php" . $website .

"&pwd=" . $pwd . "&action=check&pseid=" . $psecode .

"&amt=" . $amt;

curl_setopt($ch, CURLOPT_URL, $curl_url);

curl_setopt($ch, CURLOPT_POST, 1);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//不直接输出,返回到变量

$curl_result = curl_exec($ch);

$result = explode(',', $curl_result);

curl_close($ch);

print_r($result);

?>

getpost2.php的内容如下:

复制代码 代码如下:

<?php

echo "returndata<br>";

echo "<pre>";

print_r($_REQUEST);

echo "</pre>";

?>

结果输出:

复制代码 代码如下:

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:http://scripts.incutio.com/httpclient/

复制代码 代码如下:

<?php

require_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);

?>
