HttpClient(Apache)-在线登录 [英] HttpClient (Apache) - online Login

问题描述

我正在尝试登录Internet页面.我一直在做古怪的尝试，试图找到实现这一目标的正确方法.我到目前为止所得到的是:

我正在使用Apache包(HttpClient，代码，日志记录).

Hi,

I''m trying to login on an internet Page. I''ve been googeling and trying to find the right way to achieve this. What i got this far is:

I''m using the Apache package (HttpClient, Code, Logging).

import java.io.*;

import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.cookie.CookiePolicy;
import org.apache.commons.httpclient.methods.PostMethod;
import org.apache.commons.httpclient.Header;

public class TestCode {

	static final String loginSite = "****";
	static final String checkSite = "****"; 
	
	public static void main(String[] args) throws Exception{

		HttpClient client = new HttpClient();

              cient.getParams().setCookiePolicy(CookiePolicy.BROWSER_COMPATIBILITY);
		PostMethod post = new PostMethod(loginSite);

		post.setRequestHeader(new Header("User-Agent", "****"));
		
		post.addParameter("name","****");
		post.addParameter("password","****");
		post.addParameter("button_name","****"); //<--Press Button?
		
		client.executeMethod(post);

		
		BufferedReader in = new BufferedReader(
				new InputStreamReader(
						post.getResponseBodyAsStream()));

		String decodedString;
		
		while ((decodedString = in.readLine()) != null) {
			System.out.println(decodedString);
		}
		in.close();
				
		post.releaseConnection();
				 
	}
	
}

这是我要登录的Internet Packe:

This is the Internet Packe i''m trying to log in:

<<pre lang="xml">form method="post" name="post_name" action="TMP.php">
    <table cellpadding="1" cellspacing="1" id="login_form">
        <tbody>
            <tr class="top">
                <th>Enter Name:</th>
                <td>
                    <input class="text" type="text" name="name" value="Login_Name_Here" /> <span class="error"> </span>
                </td>
            </tr>
            <tr class="btm">
                <th>Enter Password:</th>
                <td>
                    <input class="text" type="password" name="password" value=""
                    maxlength="20" /> <span class="error"> </span>
                </td>
            </tr>
        </tbody>
    </table>
    <p class="btn">
                <input type="image" value="login" name="button_name" onclick="xy();" id="btn_login" class="dynamic_img" src="img/x.gif" alt="Login-Button" />
        <input type="hidden" name="w" value="" />
        <input type="hidden" name="login" value="99999999" />
    </p>
</form>

在回应中，我输入了密码&名称已填写.

我不确定是否必须按下"按钮.

同样，我们仍然在登录页面上得到响应(名称和密码ist过滤在值"下).

通常，当我在浏览器中登录时，i-net页面会将我发送到其他页面
(只需更改页面:TMP.php).

有人有线索吗?

提前谢谢.

好，又是我，

现在，我正在尝试一个更简单的示例.没有登录！
但是我还是不懂PostMethod ...

什么有效我了解的是GetMethod:
http://hc.apache.org/httpclient-3.x/tutorial.html
->我获得了互联网页面的信息.

但是PostMethod仍然不起作用:
http://hc.apache.org/httpclient-3.x/methods/post.html
->在这里，我得到了相同的信息(例如与GetMethod一样)

有没有人在现有的互联网页面上运行PostMethod示例?

感谢您提供任何帮助

In the response i get, the password & name is fild in.

I''m not sure if i have to "press" the Button or not.

Also wenn i get the response i''m still on the login page (name & password ist fild in the under "value").

Usually when i login on my browser the i-net page sends me to an other page
(Just changed the page: TMP.php).

Anyone has a clue?

Thanks in advance.

Ok, it''s me again,

right now i''m trying on an easier example. No login!
But still i don''t get the PostMethod...

What works & and what i understand is the GetMethod:
http://hc.apache.org/httpclient-3.x/tutorial.html
-> I get the information of the internet page.

But what doesn''t work still is the PostMethod:
http://hc.apache.org/httpclient-3.x/methods/post.html
-> Here I get the same information (like with GetMethod)

Has anybody a working PostMethod example on an excisting internet page??

Any help is appreciated
