Java从网页获取JavaScript内容

Question

I'm looking to get data from Betfair live stats of football. I have found a link to the stats part of the webpage, which is here:

https://wab-visualisation.performgroup.com/csb/index.html?wbuserId=0&token=f6eb1c7fff3ad3ca5153b159ac4b8b69fcb117ec7578893e5c9f9f6a608503fe4e64ebad85c7e4faa8ddea4e8ce70e99ce88551b77b8fe02616b56bf89af950ad89984a1cfcc8eb589dd1679b8204e8e0983fdff5c7599d00cabd805c0bd18aaf29485b0c122413c89ad5f7e70684e5f1609dea97f05286919f137baab64d36b&width=374&height=214&cssdiff=https%3a%2f%2fassets.cdnbf.net%2fstatic%2fdatavis%2fbf-css%2fbetfair1.css&flash=y&streamonly=true&partnerId=7&statsswitch=false&lang=en&defaultview=stats&version=1.15

(The page changes regularly, so please check https://www.betfair.com/sport/inplay and select any match, then get the source of the "match panel" on the left)

However, when I try to scrape this with JSoup, it doesn't seem to return anything.

    Document doc = Jsoup.connect("https://wab-visualisation.performgroup.com/csb/index.html?wbuserId=0&token=f6eb1c7fff3ad3ca5153b159ac4b8b69fcb117ec7578893e5c9f9f6a608503fe4e64ebad85c7e4faa8ddea4e8ce70e99ce88551b77b8fe02616b56bf89af950ad89984a1cfcc8eb589dd1679b8204e8e0983fdff5c7599d00cabd805c0bd18aaf29485b0c122413c89ad5f7e70684e5f1609dea97f05286919f137baab64d36b&width=374&height=214&cssdiff=https%3a%2f%2fassets.cdnbf.net%2fstatic%2fdatavis%2fbf-css%2fbetfair1.css&flash=y&streamonly=true&partnerId=7&statsswitch=false&lang=en&defaultview=stats&version=1.15").get();

    doc.select("#in-game-stats > div:nth-child(1) > div.si-home-value").text();

Am I doing something wrong? Is there a way around this?

Thanks

The response is in plain text, there is no DOM that you can query. You might want to look at Selenium with PhantomJS driver to emulate user-agent actions. Whether it's legal to scape data from that site or not, is another question.
