有一個(gè)網(wǎng)站A（比如http://162.168.0.2/query.jsp）提供某個(gè)查詢(xún)功能
這個(gè)功能只接受post方式提交的表單，并且反回一個(gè)比較簡(jiǎn)單的頁(yè)面
如何在機器B（162.168.0.1）上編寫(xiě)程序向A發(fā)出訪(fǎng)問(wèn)，然后得到那個(gè)返回的頁(yè)面？
是不是用什么header一類(lèi)的東西？
最好大蝦能給一段代碼
不知道我說(shuō)明白問(wèn)題沒(méi)有^_^

String sTmp="http://162.168.0.2/query.jsp";
try{  
URL url=new URL(sTmp);
>>>>>>>>>> HttpURLConnection connect =(HttpURLConnection) url.openConnection();
connect.setDoInput(true);
connect.setDoOutput(true);
BufferedReader in = new BufferedReader(new InputStreamReader(connect.getInputStream()));
String line = null;
StringBuffer content= new StringBuffer();
while((line = in.readLine()) != null){//line為返回值，這就可以判斷是否成功、
content.append(line);
}
in.close() ;
in=null;
url=null;
String msg = content.toString();
System.err.println(msg);
             
}catch(IOException ex){
ex.printStackTrace();
}catch(Exception e){
System.out.println("錯誤：");
System.out.println(e.getStackTrace());
}
}
