java - Using JSOUP to Login to ConEd website -

i have read extensively how , have tried number of different variations, can't work.

basically, want login conedison website , scrape billing history. here have:

connection.response loginform = jsoup.connect("https://apps.coned.com/cemyaccount/nonmemberpages/login.aspx?lang=eng")                     .data("_lastfocus","")                     .data("_eventtarget","")                     .data("_eventargument","")                     .data("_viewstate", viewstate)                     .data("_eventvalidation", eventvalidation)                     .data("ctl00$main$login1$username", username)                     .data("ctl00$main$login1$password", password)                     .data("ctl00$main$login1$loginbutton", "sign in")                     .useragent("mozilla/5.0")                     .method(method.post)                     .execute();              map<string, string> logincookies = loginform.cookies();              document document = jsoup.connect("https://apps.coned.com/cemyaccount/csol/billhistory.aspx?lang=eng")                     .cookies(logincookies)                     .get();              elements data = document.select("table.ctl00_main_lvbillhistory_table1");              //checking if found right page             system.out.println("document: " + document);             //checking if found table             system.out.println("data: " + data); 

i know information correct (though don't know if need pass data parameters no values).

i not getting errors, printing out login page (https://apps.coned.com/cemyaccount/nonmemberpages/login.aspx?lang=eng)

any appreciated.

thanks

• open development tools (press f12).
• select network tab option.
• up , left there round button. if it's not red, click it. record traffic.
• visit login page. enter credentials , login.
• check happens in development tools. there table there, showing files received.
• check type column. search row has value document. select it. open new screen.
• select headers , scroll down until locate request headers. there find request made browser. find there values send server.
• search parameters need. take values , hardcode them code. use same user-agent (just in case) , in general try imitate request code.

all steps above chrome browser.
