[英]I am using struts freamwork, after log out when i pressed browser back button it is going to last opened page. How to send it to log in page?
[英]get a page using java program and then send it back after filling out
我必须将其作为我的任务,这是:编写一个Java程序从服务器获取html页面,然后使用Java程序填写表单,然后将其发送回服务器。
为此,我编写了以下代码:
class htmlPageFetch{
public static void main(String[] args){
try{
Socket s = new Socket("127.0.0.1", 80);
DataInputStream dIn = new DataInputStream(s.getInputStream());
PrintWriter dOut = new PrintWriter(s.getOutputStream(), true);
dOut.println("GET /mytesting/justCheck.html HTTP/1.1\r\nHost:localhost\r\n\r\n");
boolean more_data = true;
String str;
while(more_data){
str = dIn.readLine();
if(str==null){
//Now server has stopped sending data //So now write again the inputs
//So i had written the following code but not working
dOut.println("POST /mytesting/save.php HTTP/1.1\r\nHost:localhost\r\n\r\n");
dOut.println("some=helloworld");
more_data = false;
continue;
}
System.out.println(str);
}
}catch(IOException e){
}
}
}
这是html文件:
<html>
<head>
<title>Title goes here</title>
</head>
<body>
<p>Hello world</p>
<form action="save.php" method="post">
Enter some thing here <input name="some"/>
<br/>
<input type="submit" value="Send"/>
<input type="reset" value="Cancel"/>
</form>
</body>
</html>
and the save.php just echo back the string entered.
So how to send back the filled form to the server back.
Thanks in Advance.
我强烈建议您使用JSoup(http://jsoup.org/)。 基本上,它是Java的jquery。 您可以非常轻松地获取输入字段。
