PHP CURL 实现 GET/POST数据


1: 使用Curl组件GET/POST数据


//Curl Get数据
function curl_get($url) {     
    $ch=curl_init();   
    curl_setopt($ch,CURLOPT_URL,$url);    
    curl_setopt($ch,CURLOPT_HEADER,0);   
    curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);    
    $data=curl_exec($ch);       
    curl_close($ch);     
     if ($data)  
         return$data;    
     else
         returnfalse;    
}     

//Curl Post数据
function curl_post($url,$vars) {      
    $ch=curl_init();   
    curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);     
    curl_setopt($ch,CURLOPT_URL,$url);    
    curl_setopt($ch,CURLOPT_POST,1);    
    curl_setopt($ch,CURLOPT_POSTFIELDS,$vars);    
    $data=curl_exec($ch);       
    curl_close($ch);     
     if ($data)  
         return$data;    
     else
         returnfalse;    
}

2: fsockopen手工GET/POST数据

//直接POST数据
function post_file($host,$file,$vars){
        $fp=fsockopen($host,80,$errno,$errstr,10);
         if (!$fp) {
                 echo”Socket Error: $errstr ($errno)\n”;
                 returnfalse;
         }
        $post.=”POST $file HTTP/1.1\r\n”;
        $post.=”Host: $host\r\n”;
        $post.=”User-Agent: $_SERVER[HTTP_USER_AGENT]\r\n”;
        $post.=”Keep-Alive: 300\r\n”;
        $post.=”Connection: keep-alive\r\n”;
        $post.=”Referer: http://$host”;
        $post.=”Content-Type: application/x-www-form-urlencoded\r\n”;
        $post.=”Content-Length: “.strlen($vars) .”\r\n”;
        $post.=$vars;
        $post.=”\r\n\r\n”;

        fwrite($fp,$post);
         while (!feof($fp)) {
                $res=fread($fp,1024);
         }
        fclose($fp);
         return$res;
}

//直接GET数据
function get_file($host,$file){
        $fp=fsockopen($host,80,$errno,$errstr,10);
         if (!$fp) {
             echo”SocketError: $errstr ($errno)\n”;
             returnfalse;
         }
        $get=”GET $file HTTP/1.1\r\n”;
        $get.=”Host: $host\r\n”;
        $get.=”User-Agent: $_SERVER[HTTP_USER_AGENT]\r\n”;
        $get.=”Referer: http://$host\r\n”;
        $get.=”Connection: Close\r\n\r\n”;

        fwrite($fp,$get);#p#分页标题#e#
         while (!feof($fp)) {
                 echofread($fp,1024);
         }
        fclose($fp);
}


3:
$data= array (‘foo’=>’bar’,’bar’=>’baz’);
$data=http_build_query($data);

$context_options= array (
        ‘http’=> array (
            ‘method’=>’POST’,
            ‘header’=>”Content-type: application/x-www-form-urlencoded\r\n”
                .”Content-Length: “.strlen($data) .”\r\n”,
            ‘content’=>$data
            )
         );

$context=context_create_stream($context_options)
$fp=fopen($url,’r’,false,$context);

//file_get_contents($url,false,$context);

————————————————————-

 


$url=’http://www.awzsr.com/’;  
   
//目标来源页面  
$referer=’http://www.awzsr.com/’; 
       
//如果目标网站需要登录,可以在这里写入模拟的Cookie值  
$cookie=”;  
      
//将$post_data中写入你所截取的数据包,可以使用Winsock Expert截取数据包  
$post_data=’uid=49940&tid=35&l=0&m=0&c=2′;  
       
//部分网站验证浏览器信息,可以在下面模拟浏览器,可以直接将USERAGENT复制到这里面  
$useragent=”;  
       
//下面的内容禁止修改  
$ch = curl_init();  
curl_setopt($ch, CURLOPT_POST, 1);  
curl_setopt($ch, CURLOPT_HEADER, 0);  
curl_setopt($ch, CURLOPT_URL,$url);  
curl_setopt($ch, CURLOPT_REFERER, $referer);  
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);  
curl_setopt($ch, CURLOPT_COOKIE,$cookie);  
curl_setopt($ch, CURLOPT_USERAGENT,$useragent);  
$result = curl_exec($ch);

 

php socket 实现POST GET操作

    if([email protected]_write($fsock, $in, strlen($in))){
