Occasionally try today, found that today's headline information data is by js request returns json data,

is the link and find the as and cp parameter value is variable, from home_583c7a0. Js files found function

changed to Java method, but if not, the warrior to see which can also improve

} 
Map The map=new HashMap<> (a); 
The map. The put (" as ", as); 
The map. The put (" cp ", cp); 
return map; 
} 

, and finally the value of a parameter _signature also need a dynamic access?
