我正在尝试在使用XmlHttpRequest（XHR提交表单的网站）上自动化表单填写过程。该网站似乎正在使用jsf进行部分呈现。浏览器对表单提交请求的网络检查如下：

相应的Jsoup代码：
Connection connection = Jsoup.connect("https://parivahan.gov.in/rcdlstatus/vahan/rcDlHome.xhtml")
.userAgent("Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:66.0) Gecko/20100101 Firefox/66.0")

.timeout(10000);
Log.d(TAG,"Sending Post request :" + connection.request().data());
Document document = connection.post();
statusCode = connection.response().statusCode();
Log.d(TAG,"Response Status code:"+statusCode);
已获得答复：

<update id="form_rcdl:j_idt15">

现在的问题是，尽管响应的状态码为200 OK，但我没有从站点获得预期的响应。我在这里想念什么？
