基本下面的代码是表格
<form NAME='login' METHOD='POST' ACTION='authentication.php'>
<table width="350" height="181"cellpadding='0' cellspacing='0' border='0' style="border:#e5e5e5 0px solid; BACKGROUND: url(css/images/top9.png) no-repeat left top;" align="center">
<tr> <td rowspan="6" style="padding-left:15px;"><img src="css/images/groupperms.gif" width="50" height="50"><td></tr>
<tr>
<td colspan="2" height="50"></td>
</tr>
<tr>
<td nowrap><span class="textcolor1">Account No. </span></td>
<td><input type='text' name='username' style="border:#cacaca 2px solid; color:#000099;" value=''></td></tr>
<tr>
<td> <a class="uiTooltip" href="#" onMouseOver="ajax_showTooltip(window.event,'tooltip/help.html',this);return false" onMouseOut="ajax_hideTooltip()">Help</a></td>
<td><input name="login" type='submit' value='Login' style="width:80px; font-family:Arial, Helvetica, sans-serif; font-weight:bold; color:#FFFFFF; border:#000000 2px solid; cursor:pointer; background-color: #1b4585;" border="0" align="right" title="Login" onClick="return checkLogin();"/></td>
</tr>
</table>
</form>
我正在尝试这个
package jsouptest;
import org.jsoup.Connection;
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
public class JsouptTest {
public static void main(String[] args) throws Exception {
Connection.Response loginForm = Jsoup.connect("https://www.desco.org.bd/ebill/login.php")
.method(Connection.Method.GET)
.execute();
Document document = Jsoup.connect("https://www.desco.org.bd/ebill/login.php")
.data("cookieexists", "false")
.data("username", "32007702")
.data("login", "Login")
.cookies(loginForm.cookies())
.post();
System.out.println(document);
}
}
但我得到了低于错误

我缺少什么？如何修复它？
am is missing something? how to fix it?
推荐答案
你用来执行POST请求的URL是错误的，只是因为当你必须对表格做一个特定的请求，你应该使用表格标签中的网页，在这种情况下authentication.php。
The URL that are you using in order to do the POST request is wrong, simply because when you have to do a specific request to a form you should use the web page that is present in the form tag, in this case "authentication.php".
所以代码将是：
package jsouptest;
import org.jsoup.Connection;
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
public class JsouptTest {
public static void main(String[] args) throws Exception {
Connection.Response loginForm = Jsoup.connect("https://www.desco.org.bd/ebill/login.php")
.method(Connection.Method.GET)
.execute();
Document document = Jsoup.connect("https://www.desco.org.bd/ebill/authentication.php")
.data("cookieexists", "false")
.data("username", "32007702")
.data("login", "Login")
.cookies(loginForm.cookies())
.post();
System.out.println(document);
}
}
这个正确检索你想要的网页。
This one correctly retrieves the web page that you want.
