我想使用java登录网站。我使用org.apache.http,我已经写了
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<mpl=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,但我仍然无法登录。我要登录的网站是http://www.xtratime.org/forum/有任何想法或有不同的方式吗?
答案 0 :(得分:5)
<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,请对密码进行编码(onsubmit
)。您应该在代码中执行相同的操作。
action
属性的值与您的代码(https://accounts.google.com...
)不匹配。您应该将帖子请求发送到login.php?do=login
。
还有很多隐藏的领域:
<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。
通常安装HttpFox Firefox Add-on更容易检查post参数的请求而不是解码javascript。
我的浏览器发送这些帖子参数(使用HttpFox捕获,密码为pass1
):
vb_login_username: user1
vb_login_password:
s: 5d8bd41a83318e683de9c55a38534407
securitytoken: 0dcd78b4c1a376232b62126e7ad568e0d1213f95
do: login
vb_login_md5password: a722c63db8ec8625af6cf71cb8c2d939
vb_login_md5password_utf: a722c63db8ec8625af6cf71cb8c2d939
修改强>:
以下对我有用,我可以在打印的html代码中获取“感谢您登录”消息:
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();
}

我建议您使用htmlunit:
HtmlUnit是“用于Java程序的GUI-Less浏览器”。它模拟HTML 文档并提供一个API,允许您调用页面,填写 表格,点击链接等...就像你在“正常”中做的那样 浏览器。
它有相当不错的JavaScript支持(不断改进) 并且能够使用非常复杂的AJAX库进行模拟 Firefox或Internet Explorer,具体取决于您的配置 想用。
它通常用于测试目的或检索信息 来自网站。
