java 脚本，带有 httpclient 的 post 方法

Question

I am trying to login to yahoo.de with httpclient in java (I am crawling the site). To submit a form having username and password, I use Postmethod. I found that I have to pass some hidden values (which are generated dynamically) along with username and password in post method. Does anybody know how do I do this? How do I handle javascript with httpclient? Any help would be appreciated !

Answer 1

I doubt HTTPClient would support java-script, you might have to find if Yahoo supports non-javascript login process in the page and grasp those fields to login through.

Otherwise use, yahoo's open-id API to authenticate the user. More information here: http://developer.yahoo.com/openid/
