可以清除的看到这里的发送没有加密，接受有加密。

接收解密

有枣没枣打三棒子，直接找拦截器。

找到拦截器，查看 response 部分的内容。

其实这里直接就有了，下面是解密 JS：

var u = require("crypto-js")

function fn(data) {
    var l = "QV1f3nHn2qm7i3xrj3Y9K9imDdGTjTu9"
    var n = u.enc.Utf8.parse(l)
      , r = u.AES.decrypt(data, n, {
        mode: u.mode.ECB,
        padding: u.pad.Pkcs7
    })
      , i = r.toString(u.enc.Utf8)
      , s = JSON.parse(i);

    return s;
}
