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。
代码如下:
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 = "";
$url = ""; $http = Http::create()->init($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 $http->post(array(
'User-Agent' => 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML,
),array('username'=>'发一个中文','age'=>22));
php 模拟 http请求
方法一：利用php的socket编程来直接给接口发送数据来模拟post的操作。
建立两个文件post.php,getpost.php post.php内容如下：
代码如下:
'abc',
'var2'=>'how are you,my friend??');
//构造要post的字符串
foreach ($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
$fp = fsockopen("localhost",81,$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); ?>
代码如下:
PHP
echo "this is the data posted";
echo "
"; print_r($_REQUEST); echo ""; ?>
结果输出：
代码如下:
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：
代码如下:
PHP
$psecode = 'NDE005';
$website = 'www.baidu.com';
$amt = 1;
$pwd = 123456;
$ch = curl_init();
$curl_url = "=" . $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：
代码如下:
PHP
echo "returndata
"; echo "
"; echo "
"; print_r($_REQUEST); echo ""; ?>
结果输出：
代码如下:
returndataArray
(
[web] => 'wwwbaiducom'
[pwd] => 123456
[action] => check
[pseid] => 'NDE005'
[amt] => 1
)
)
方法三：
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);
