Recently I am working on extraction for youku website for a week. I find there are two bugs in current extraction.

• First bug: #14932
• Second bug: #15090

Yesterday I found a new api from Chrome when I visit youku.com. Here is the api : http://acs.youku.com/h5/mtop.youku.play.ups.appinfo.get/1.1/

I want to implement this algo but I failed (This is why I create this issue). I put my test code from Chrome here. I have remove redundant query params.

param = {

    't': ts,

    'data': data
}
a = requests.get("http://acs.youku.com/h5/mtop.youku.play.ups.appinfo.get/1.1/", params=param)
print a.text

I received below result.

{"api":"mtop.youku.play.ups.appinfo.get","data":{},"ret":["FAIL_SYS_TOKEN_EMPTY::令牌为空"],"v":"1.1"}

Now I have two question.

• First : how to cal sign .
• Second: how to get ckey

This may be useful for sign: https://www.sslcvm.com/2017/12/07/68.html

And I remember the content of ckey is embedded in a Javascript file
