我想登录到特定网站，但如果要这样做，我需要从网上获取一些隐藏数据。在所有下一个部分中，它不同，所以我必须保持sesion活着我想。 要检查我是否已登录，我想转到此特定网站的另一个页面（您必须登录才能看到它）
好的，我收到回复，我的信息为LOGIN，HIDDEN_NAME和HIDDEN_VALUE为2 然后我想通过邮寄方式登录表格，传递和登录所需的数据。
这就是我这样做的方式，它不起作用：

怎么了？为什么不工作？
答案 0 :(得分：0)
我使用Jsoup
而不是HttpClient API我创建了获取登录数据的方法
public Connection.Response getLoginData() {
Connection.Response res = null;
try {
String html;
int length, counter;
res = Jsoup
.connect("https://bannersbroker.com//user/login?event=doLogin")
.execute();
html = res.parse().toString();
length = html.length();
counter = 0;
for (int i = 0; i < length; i++) {
if (html.startsWith("document.write", i)) {
name[counter] = html.substring(i + 41, i + 144);
value[counter] = "Login";
counter++;
}
if (html.startsWith("hidden", i)) {
name[counter] = html.substring(i + 13, i + 81);
value[counter] = html.substring(i + 90, i + 123);
counter++;
}
}
} catch (IOException ioe) {
} catch (NullPointerException ioe) {
JOptionPane.showMessageDialog(RunFrame.getInstance(),
"Could not open connection to Banners Broker!",
"Error",
JOptionPane.ERROR_MESSAGE);
}
return res;
}
然后我用其他方法登录
public Connection.Response doLogin(Connection.Response res, String email, String pass) {
Connection.Response res2 = null;
try {
res2 = Jsoup
.connect("https://bannersbroker.com//user/login?event=doLogin")
.cookies(res.cookies())
.data("email", email)
.data("pass", pass)
.data(name[0], value[0])
.data(name[1], value[1])
.data(name[2], value[2])
.method(Connection.Method.POST)
.execute();
} catch (IOException ioe) {
} catch (IllegalArgumentException ioe) {
JOptionPane.showMessageDialog(RunFrame.getInstance(),
"Could not open connection to Banners Broker!",
"Error",
JOptionPane.ERROR_MESSAGE);
} catch (NullPointerException ioe) {
JOptionPane.showMessageDialog(RunFrame.getInstance(),
"Could not open connection to Banners Broker!",
"Error",
JOptionPane.ERROR_MESSAGE);
}
return res2;
}
我在我的类的construcxtor中调用方法，并从一个响应发送到另一个。
当我登录时，我处理来自方法doLogin()的重新定位
这是我如何解析数据
doc = Jsoup
.connect(pageAddres)
.cookie("PHPSESSID", res.cookie("PHPSESSID"))
.get();
