Jsoup Cookies for HTTPS scraping

Brian picture Brian · Aug 21, 2011 · Viewed 30.4k times · Source

I am experimenting with this site to gather my username on the welcome page to learn Jsoup and Android. Using the following code

Connection.Response res = Jsoup.connect("http://www.mikeportnoy.com/forum/login.aspx")
    .data("ctl00$ContentPlaceHolder1$ctl00$Login1$UserName", "username", "ctl00$ContentPlaceHolder1$ctl00$Login1$Password", "password")
    .method(Method.POST)
    .execute();
String sessionId = res.cookie(".ASPXAUTH");

Document doc2 = Jsoup.connect("http://www.mikeportnoy.com/forum/default.aspx")
.cookie(".ASPXAUTH", sessionId)
.get();

My cookie (.ASPXAUTH) always ends up NULL. If I delete this cookie in a webbrowser, I lose my connection. So I am sure it is the correct cookie. In addition, if I change the code

.cookie(".ASPXAUTH", "jkaldfjjfasldjf")  Using the correct values of course

I am able to scrape my login name from this page. This also makes me think I have the correct cookie. So, how come my cookie comes up Null? Are my username and password name fields incorrect? Something else?

Thanks.

I know I'm kinda late by 10 months here. But a good option using Jsoup is to use this easy peasy piece of code:

//This will get you the response.
Response res = Jsoup
    .connect("url")
    .data("loginField", "[email protected]", "passField", "pass1234")
    .method(Method.POST)
    .execute();

//This will get you cookies
Map<String, String> cookies = res.cookies();

//And this is the easieste way I've found to remain in session
Documente doc = Jsoup.connect("url").cookies(cookies).get();

Though I'm still having trouble connection to SOME websites, I connect to a whole lot of them with the same basic piece of code. Oh, and before I forget.. What I figured my problem is, is SSL certificates. You have to properly manage them in a way I still haven't quite figured out.
