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);
}

$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
