清楚缓存，重新打开app, 点击同意按钮，会触发设备注册；

很明显是一个post包，device\_register  
可以看到请求体加密了 那么 请求体是什么呢？

> 很老版本思路：都是直接明文注册  
> 较老版本思路：在反编译后请求体通过一个bool来判断，是否走，ttencrypt；  
> 这个地方可以hook明文也可以直接修改bool值，让抓包直接抓到明文；
> 
> 正常情况下，是将请求体压缩后，走ttencrypt，进行密文注册；

我们接着往下走，看新版是否有变化；

看下params参数：

### cdid: ###

只找到个从SharedPreferences xml拿，没有就uuid;

### openudid: ###

--------------------

### x\_ss\_stub： ###

这个值就很普通了，java层，post包的时候会把data转成字符串进行md5的一个值；

搜出来个这玩意，兄弟们想想这是干啥，注册，激活。。

### ttencrypt： ###

搜一下：/service/2/device\_register/

                                        th = th4;
                                        l4Q.LIZ(Monitor.Key.register, Monitor.State.f_net);
                                        l5O l5o22 = this.LIZJ;
                                        changeQuickRedirect = l5O.LIZIZ;
                                        if (PatchProxy.isEnable(changeQuickRedirect)) {
        
                                        }
                                        if (th instanceof CommonHttpException) {
        
                                        }
                                    }
                                }
                            }
                            return false;
                        }
                        throw new IllegalArgumentException("url is null");
                    }
                }
                strArr = (l5V.LIZIZ == null || l5V.LIZIZ.length <= 0 || StringUtils.isEmpty(l5V.LIZIZ[0])) ? new String[]{
        O.C("https://", l5V.LIZLLL, "/service/2/device_register/"), O.C("https://", l5V.LIZLLL, "/service/2/device_register/")} : l5V.LIZIZ;
                if (strArr == null) {
        
                }
            } catch (Throwable unused2) {
        
                l4Q.LIZ(Monitor.Key.register, Monitor.State.f_exception);
                return false;
            }
        }

可以看到整个注册这个接口的流程；

这一段代码是核心，看到是发请求去了；

> import com.ss.android.common.applog.NetUtil;

str2 = NetUtil.sendEncryptLog(C, bArr, this.LIZJ.LJIILL, false, (String[]) null, (Map) null, (String) null, z, false);
    
    str2 = NetUtil.doPost(str3, bytes, true, "application/json; charset=utf-8", false, (Map) null, z, false);

**这个时候，我们看出来已经和老版本有区别了，没有一个bool值来控制是否请求加密，而是直接去加密，若报错才会进行明文注册； 这是一点不同的地方；**

doPost： 确实没啥东西；

sendEncryptLog：

如果包含str.contains(“/service/2/app\_log/”）就去走ttEncrypt 加密，目前走else  
![在这里插入图片描述][dd54aea6570f44b98c48c308fdcb83d1.png]  
else: 也是压缩 ttEncrypt 加密

ttEncrypt 该加密方式so层，libEncryptor.so

我们在看下，整体接口：

看到确实是发了很多接口，注册，激活，日志包等等；而且必须是六神注册，密文注册，这样设备才可用；

很明显的，device\_register，app\_alert ，app\_log等等

为了权重更好，甚至注册完之后还需要发一些日志包，过一些验证码，提高设备权重；
