用java登录网站 [英] Login on website with java

问题描述

我想使用java登录网站。我使用org.apache.http而且我已经写过了

I would like to login to a website with java. I use the org.apache.http and I already written

HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("https://accounts.google.com/ServiceLogin?      service=mail&passive=true&rm=false&continue=https%3A%2F%2Fmail.google.com%2Fmail%2F%3Fhl%3Dsl%26tab%3Dwm%26ui%3Dhtml%26zy%3Dl&bsv=llya694le36z&scc=1&ltmpl=default&");
try {
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
nameValuePairs.add(new BasicNameValuePair("vb_login_username",
                    "XXX"));
nameValuePairs.add(new BasicNameValuePair("vb_login_password",
                    "XXX"));
post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = client.execute(post);
BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
String line = "";
while ((line = rd.readLine()) != null) {
System.out.println(line);
            }
} catch (IOException e) {
e.printStackTrace();
        }

它正确地发送了我已经测试的帖子表格，但我还是无法登录。我想登录的网站是 http://www.xtratime.org/forum/ 任何想法这个或有不同的方式吗？

It sends the post form correctly i have tested, though i still cant login. The website I want to login is http://www.xtratime.org/forum/ Any ideas for this or is there a different way?

推荐答案

<form action="login.php?do=login" method="post" 
    onsubmit="md5hash(vb_login_password, vb_login_md5password, 
        vb_login_md5password_utf, 0)">

• 在提交页面之前编码密码（的onsubmit ）。您应该在代码中执行相同操作。

  • Before submit the page encode the password (onsubmit). You should do the same in the code.

    操作属性的值与您的代码（ https：//accounts.google.com ... ）。您应该将发布请求发送到 login.php？do = login 。

    The value of the action attribute does not match with your code (https://accounts.google.com...). You should send the post request to the login.php?do=login.

    并且有很多隐藏字段：

    <input type="hidden" name="s" 
        value="b804473163cb55dce0d43f9f7c41197a" />
    
    <input type="hidden" name="securitytoken" 
        value="0dcd78b4c1a376232b62126e7ad568e0d1213f95" />
    
    <input type="hidden" name="do" value="login" />     
    
    <input type="hidden" name="vb_login_md5password" />
    
    <input type="hidden" name="vb_login_md5password_utf" />
    

    您也应该发送这些参数。

    You should send these parameters too.

    通常更容易安装 HttpFox Firefox附加组件并检查帖子的请求参数比解码javascript。

    Usually it's easier to install an HttpFox Firefox Add-on an inspect the request for the post parameters than decoding the javascript.

    我的浏览器发送这些帖子参数（用HttpFox捕获，密码是 pass1 ） ：

    My browser sends these post parameters (captured with HttpFox, the password is pass1):

    vb_login_username: user1
    vb_login_password:
    s: 5d8bd41a83318e683de9c55a38534407
    securitytoken: 0dcd78b4c1a376232b62126e7ad568e0d1213f95
    do: login
    vb_login_md5password: a722c63db8ec8625af6cf71cb8c2d939
    vb_login_md5password_utf: a722c63db8ec8625af6cf71cb8c2d939
    

    编辑：

    以下适用于我，我可以在打印的html中获取感谢您登录消息代码：

    The following works for me, I can get the "Thank you for logging in" message in the printed html code:

    final HttpClient client = new DefaultHttpClient();
    final HttpPost post = new HttpPost(
            "http://www.xtratime.org/forum/login.php?do=login");
    try {
        final List<NameValuePair> nameValuePairs = 
            new ArrayList<NameValuePair>(1);
        nameValuePairs.add(new BasicNameValuePair("vb_login_username",
                "my user"));
        nameValuePairs.add(new BasicNameValuePair("vb_login_password", ""));
        nameValuePairs.add(new BasicNameValuePair("s", ""));
        nameValuePairs.add(new BasicNameValuePair("securitytoken",
                "inspected with httpfox, like f48d01..."));
        nameValuePairs.add(new BasicNameValuePair("do", "login"));
        nameValuePairs.add(new BasicNameValuePair("vb_login_md5password",
                "inspected with httpfox, like 8e6ae1..."));
        nameValuePairs.add(new BasicNameValuePair(
                "vb_login_md5password_utf",
                "inspected with httpfox, like 8e6ae1..."));
    
        post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        final HttpResponse response = client.execute(post);
        final BufferedReader rd = new BufferedReader(new InputStreamReader(
                response.getEntity().getContent()));
        String line = "";
        while ((line = rd.readLine()) != null) {
            System.out.println(line);
        }
    } catch (final IOException e) {
        e.printStackTrace();
    }
