1,问题提出
发现有个聊天的app, 想看下能不能做到智能回复。
2,解决方案
2.1
Fart 砸壳,脚本批量导出java文件,安装模拟器准备运行,移动操作猛如虎,结果弹出不能模拟器运行。刚开始认为是native,360加固,是不是需要修复,想的很麻烦,后边直接打出堆栈,看到了代码。

插入代码
var bcls = Java.use("com.xm.bottle.utils.ToolUtils");
        bcls.isEmulator.overload("android.content.Context").implementation = function(arg1) {
            return false;
        }

2.2 刷新对话列表,找到有未读消息,然后自动回复

// 根据回话列表,自动回复
   var hdcls = Java.use('com.tencent.qcloud.tim.uikit.modules.conversation.holder.ConversationCommonHolder')
  // public abstract void layoutViews( com.tencent.qcloud.tim.uikit.modules.conversation.base.ConversationInfo conversationInfo, int i);
 
  hdcls.layoutViews.overload('com.tencent.qcloud.tim.uikit.modules.conversation.base.ConversationInfo','int').implementation = function(arg1,arg2) {
      //console.log('conv layoutview' + arg2);
      this.layoutViews(arg1,arg2);
      /**
       * 有未读的,则需要打开
       *
       if (conversationInfo.getUnRead() > 0) {
 
           MessageInfo lastMessage = conversationInfo.getLastMessage();
 
           public TIMMessage getTIMMessage() {
    return this.TIMMessage;
}
 
       */
      var unred = arg1.getUnRead();
      if(unred > 0) {
          var lst = arg1.getLastMessage();
          var isself = lst.isSelf();
          if(!isself) {
            var nt = lst;
            var timcls=Java.use("com.tencent.imsdk.TIMTextElem");
            var els = nt.getElement();
            var NewTypeClass=Java.cast(els,timcls);
            var rectxt = NewTypeClass.getText();
            var ret = "";
            if(rectxt.length >0) {
 
                    console.log('rect2' + rectxt);
                    //发送智能数据
                     this.itemView.value.performClick()
                    //getreps2(rectxt,'',lst);
                }
 
 
          }
      }
  }

找到handler, 找到未读>0 ,然后点击中间的view,自动打开聊天窗口。

大致意思是,hook 聊天窗口,找到最后一条,不是自己发送的消息,,然后调用智能接口,发送数据。
这里有人要问了,为什么不直接hook 发送消息,直接回复消息,还要打开界面,填入内容,然后点击发送按钮。因为风控,app 风控了这个接口
3,遗留问题
自动找人聊天,还有其他成品,或者合作,可以加我星球。

 

另外,出友盟的协议。
