Java Jsoup连接501错误

如何与Jsoup建立连接以填写和发送表单

该网站与此类似：

          <form action="the.form" method="post"
                enctype="application/x-www-form-urlencoded"
                name="start_form"
                autocomplete="off">
             <input type="hidden" value="8F5EB4CD93CAB4E093EF7C1C733791FC" name="session" />
             <input type="text" value="" name="number" />
             <div class="right">
                <input type="submit" name="submit" value="Submit" />
             </div>
          </form>

结果:

Exception in thread "main" java.io.IOException: 501 error loading URL https://www.theurl.com
    at org.jsoup.helper.HttpConnection$Response.execute(HttpConnection.java:414)
    at org.jsoup.helper.HttpConnection$Response.execute(HttpConnection.java:391)
    at org.jsoup.helper.HttpConnection.execute(HttpConnection.java:157)
    at org.jsoup.helper.HttpConnection.post(HttpConnection.java:152)
    at Test.main(Test.java:17)
