Answer 1

$username=$_POST['username'];
  $password=$_POST['password'];
   $host="www.teamsun.com.cn:88";
  $service_uri="/login.msc";
   $query_string="user=$username&password=$password&mode=submit";
   $http_request="POST ". $service_uri ." HTTP/1.1\r\n";
   $http_request.="Host:$host\r\n";
   $http_request.="Content-Type: application/x-www-form-urlencoded\r\n";
   $http_request.="Accept-Encoding: gzip, deflate";
   $http_request.="Content_Length:".strlen($query_string)."\r\n";
  $http_request.="Connection: Keep-Alive\r\n\r\n";
   $http_request.="Cache-Control: no-cache";
  
   $fs = fsockopen($host,88);
  if (!is_resource($fs)){
      echo "trackback_send: Couldn't connect to $host,Port 88"; 
       return false;
     }
     fwrite($fs, $http_request);
     while(!feof($fs))
     {
     $response.=fread($fs,8192);
     }
    fclose($fs);
    echo $response;
楼上的我是这样请求的

Answer 2

你好象只发送了  $http_request而 $query_string 什么时候送给服务器的???

Answer 3

try:
============
1.-----------------------------------
$host="www.teamsun.com.cn:88";//----->改为$host="www.teamsun.com.cn";2.-----------------------------------
$http_request="POST ". $service_uri ." HTTP/1.1\r\n";
$http_request.="Host:$host\r\n";
$http_request.="Content-Type: application/x-www-form-urlencoded\r\n";
$http_request.="Accept-Encoding: gzip, deflate";
$http_request.="Content_Length:".strlen($query_string)."\r\n";
$http_request.="Connection: Keep-Alive\r\n\r\n";
//加一行
$http_request.=$query_string."\r\n";//添加post字符串
$http_request.="Cache-Control: no-cache";

Answer 4

Content_Length:
改为 
Content-Length:
  $http_request.="Connection: Keep-Alive\r\n\r\n";
改为 
  $http_request.="Connection: Keep-Alive\r\n";
   $http_request.="Cache-Control: no-cache";
改为 
   $http_request.="Cache-Control: no-cache\r\n\r\n";
$fs = fsockopen($host,88); 前面添加$http_request .= $query_string."\r\n\r\n";问题比较多.建议你先去看看HTTP协议或者,你先去抓个包.然后按包写....

Answer 5

$http_request.="Connection: Keep-Alive\r\n\r\n";
   =>
$http_request.="Connection: close\r\n\r\n";

还是出现同样的错误,我用iris抓的包

Answer 7

POST /login.msc HTTP/1.1
Host:www.teamsun.com.cn
Content-Type: application/x-www-form-urlencoded
Accept-Encodeing: gzip, deflate
Content-Length: 35
Connection: Keep-Alive
Cache-Control: no-cacheuser=test&password=test&mode=submit

php编程我是个新手,抓的包基本上和你写的差不多,referer,accept,Accept-Language这些参数还要写上吗,不是必须的吧

Answer 9

你严格按照抓的包写,一般是不会有大的问题....你把我的包复制...开个TELNET 到 88 端口.粘贴进去. 就可以看到了...
不会出400错误.只会出302  因为用户名密码不对.
