JS 逆向爬虫——欧科云连

js:

 1 function encryptApiKey() {
 2     var t = "a2c903cc-b31e-4547-9299-b6d07b7631ab";
 3     var  e = t.split("");

 5     return e.concat(r).join("")
 6 }
 7 function encryptTime(t)

 9             var e = (1 * t + 1111111111111).toString().split("")
10               , r = parseInt(10 * Math.random(), 10)
11               , n = parseInt(10 * Math.random(), 10)
12               , o = parseInt(10 * Math.random(), 10);
13             return e.concat([r, n, o]).join("")
14         }
