post请求页面的问题

[clius]

一个普通的HTML页面中有一个form,定义如下:
<form name="form2" method="post" action="query.asp" >
form里有一个文本输入框和一个submit按钮,输入值并点击submit按钮后提交给/query.asp文件.怎么用java模拟这个submit按钮,带上一个参数,提交并访问/query.asp页面的内容?(注意:/query.asp的内容是由post那个参数的不同而产生不同的内容!)

Socket或者Url

[clius]

我知道，可是相应的url不能直接写，好像要自己写http头，但是我写了出现如下的错误
HTTP/1.1 405 Method not allowed
Date: Thu, 25 Sep 2003 12:03:07 GMT
Server: Microsoft-IIS/5.0
Vary: *
Allow: OPTIONS, TRACE, GET, HEAD

不知道是不是我写的方法不对，请指教

把method改成GET看看

[eric_uugames]

使用javascript不久得了吗

<form name=myform action=..>
<input type=hidden name=user>
<input type=hidden name=pass>
</form>
<script language=JavaScript>
myform.user='houzongming';
myform.pass='mima';
myform.submit;
</script>

[clius]

to fishbob21：我用了get，还是不行

to hzmhzmhzm：我这里用java写的，是程序的一小部分，主要去网上取点数据，呵呵，javascript不太会。

我大概知道就是cookie的问题，但是不知道具体怎么操作。

[clius]

请高手指定啊，急死了

[clius]

我首先建立了一个连接取得cookie，然后在建立一个连接使用获得的cookie连同文本框的内容一起发到query.asp中，为什么总是出现 Server returned HTTP response code: 405 的错误呢？

[slaser]

客户端用java有什么好的，看看apache上的HttpClient吧。免得写那么多东西。

[clius]

谢谢slaser，可是我没什么头绪，能否说的详细些

用这种格式:
发送必须是这种格式的，特别是回车换行，多个少个都不行:

}

具体的协议怎样的w3c有关于Http的解释,忘记在哪儿了,自己找吧
如果对传文件的不是这样的得查文档

[clius]

下面是我的程序，请高手看看哪里错了啊

import java.io.*;
import java.net.*;
import java.util.*;

public class HttpCookie {
private static String[] header = {"POST /query2.asp HTTP/1.1\r\n",
"Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/vnd.ms-powerpoint, application/vnd.ms-excel, application/msword, application/x-shockwave-flash, */*\r\n",

header[11] = cookie;
//要发送的http头
String cmd = "";
for(int i = 0; i < header.length; i++){
cmd += header[i];
}

URL url = new URL("http://www.e-shrailway.com");
URLConnection uc = url.openConnection();
uc.setDoOutput(true);
uc.setDoInput(true);

sender.write(cmd.getBytes(),0,cmd.length());
sender.flush();

String line = "";
BufferedReader br = new BufferedReader(new InputStreamReader(uc.getInputStream()));
while((line = br.readLine()) != null){
System.out.println(line);
}
br.close();
}catch(java.net.MalformedURLException e){
e.printStackTrace();
}catch(java.io.IOException e){
e.printStackTrace();
}
}
}

以下是抛出的异常

java.io.IOException: Server returned HTTP response code: 405 for URL: http://www.e-shrailway.com


怎么没人回答啊，立即就给分的，不够再加
