在java中使用socket填充html表单

8 月，1 周 Questions & Answers 2288

嘿，我正试图用java程序填充html表单，但我半途而废。实际上，我能够获取页面，但无法将其写回服务器，或者可能能够将其写回，但服务器没有响应

以下是我的节目：

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

public class fillForm{
    public static void main(String args[]){
        Socket s = null;
        try{
            s = new Socket("localhost", 80);
            BufferedReader br = new BufferedReader(new InputStreamReader(s.getInputStream()));
            BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));
            /******************
              Now download the page from the server.
             ******************/
            bw.write("GET /phpsandbox/form.html HTTP/1.1\n");
            bw.write("Host: localhost:80\n\n");
            bw.flush();
            readResponse(br);
            //now i have read whole input now its time to write output.
            bw.write("GET /phpsandbox/form.php?uName=hello HTTP/1.1\n");
            bw.write("Host: localhost:80\n\n");
            bw.flush();
            readResponse(br);
        }catch(IOException e){
            System.out.println("IO: " + e.getMessage());
        }catch(Exception e){
            System.out.println("Exception: " + e.getMessage());
        }                   
    }
    public static void readResponse(BufferedReader br){
        String newLine;
        try{
            while((newLine = br.readLine())!=null){
                System.out.println("Line: " + newLine);
            }
        }catch(IOException e){
            System.out.println("IO: " + e.getMessage());
        }
    }
}

这是表格。html

<html>
<head><title>form</title></head>
<body>
<form action="form.php" method="GET">
<label>Enter name</label>
<input name="uName"/>
<input type="submit" />
</form>
</body>
</html>

这是表格。php与表单位于同一文件夹中。html

<?php
        //read the response from the client
        echo "hELLO";
        echo $_GET['uName'];
?>

以下是输出：

Line: HTTP/1.1 200 OK
Line: Date: Sun, 06 Feb 2011 13:46:17 GMT
Line: Server: Apache/2.2.11 (Unix) DAV/2 mod_ssl/2.2.11 OpenSSL/0.9.8k PHP/5.2.9 mod_apreq2-20051231/2.6.0 mod_perl/2.0.4 Perl/v5.10.0

Line: <html>
Line: <head><title>form</title></head>
Line: <body>
Line: <form action="form.php" method="GET">
Line: <label>Enter name</label>
Line: <input name="uName"/>
Line: <input type="submit" />
Line: </form>
Line: </body>
Line: </html>

给出输出后，程序等待一段时间，然后退出

谢谢：）
