/**
使用说明
首先将 okhttpfind.dex 拷贝到 /data/local/tmp/ 目录下
例：frida -U -l okhttp_poker.js -f com.example.demo --no-pause
接下来使用okhttp的所有请求将被拦截并打印出来；
扩展函数：
    find()                                         检查是否使用了Okhttp & 是否可能被混淆 & 寻找okhttp3关键类及函数
    switchLoader(\"okhttp3.OkHttpClient\")         参数：静态分析到的okhttpclient类名
    hold()                                         开启HOOK拦截
    history()                                      打印可重新发送的请求				
    resend(index)                                  重新发送请求		

备注 ： okhtpfind.dex 内包含了 更改了包名的okio以及Gson，以及Java写的寻找okhttp特征的代码。
okhttpfind.dex 源码链接 https://github.com/siyujie/okhttp_find

原理：由于所有使用的okhttp框架的App发出的请求都是通过RealCall.java发出的，那么我们可以hook此类拿到request和response,
也可以缓存下来每一个请求的call对象，进行再次请求，所以选择了此处进行hook。
