Xposed第五课(微信篇) 聊天机器人

经过了前段日子基于微信的学习，今天终于折腾除了一点干货，微信聊天机器人。先上个图

一对一聊天	群聊

为了完成这个，人都蒙蔽了，不多说了开始分析把。

首先进行如下图的操作

DDMS	轨迹
QQ截图20180612223149.png	QQ截图20180612223157.png

左图选中要记录的进程点击左图右上角那个图标进行轨迹录制之后，再次点击这个停止录制，就有了右边的图，我是从点击微信发送按钮开始录制的，所以在有图下面输入过滤关键字 onClick

public final boolean FZ(String str) {
        mS(false);
        ctQ();
        return this.yOg.yRO.dt(str, 0);
    }

从这个开始入手进入 dt(String str, int i)

public final boolean dt(String str, int i) {
        ...此处省略...
        this.ejx.cuJ().post(new y$1(this, Xf, i));
        this.ejx.mZ(true);
        return true;
    }

接下来是关键点了，后面关联的地方有多处，我一一列出来
首先是 y$1

class y$1 implements Runnable {
    final /* synthetic */ String fNk;
    final /* synthetic */ int ra;
    final /* synthetic */ y yXJ;

    y$1(y yVar, String str, int i) {
        this.yXJ = yVar;
        this.fNk = str;
        this.ra = i;
    }

    public final void run() {
        g.vX(20);
        int i = (this.yXJ.ejx.cuz().field_username.equals("medianote") && (q.GG() & 16384) == 0) ? 1 : 0;
        if (i != 0) {
            this.yXJ.ejx.cuM();
            au.Dv().a(new a(this.yXJ.ejx.cuz().field_username, this.fNk), 0);
            return;
        }
        String cuB;
        if (this.yXJ.ejx.cuP().getCount() == 0 && x.XM(this.yXJ.ejx.ctS())) {
            br.ID().c(10076, new Object[]{Integer.valueOf(1)});
        }
        String ctS = this.yXJ.ejx.ctS();
        int hC = s.hC(ctS);
        String str = this.fNk;
        q qVar = this.yXJ.yRE;
        if (qVar.ejx.cuC()) {
            w.i("MicroMsg.ChattingUI.LbsImp", "[oneliang]encrypt:" + qVar.ejx.wG() + ",raw:" + qVar.ejx.cuB());
            cuB = bh.oB(qVar.ejx.wG()) ? qVar.ejx.cuB() : qVar.ejx.wG();
        } else {
            cuB = ctS;
        }
        if (bh.oB(cuB)) {
            w.w("MicroMsg.ChattingUI.TextImp", "tempUser is null");
            return;
        }
        ChatFooter cuS = this.yXJ.ejx.cuS();
        int i2 = this.ra;
        int i3 = cuS.vST.vTU.containsKey(ctS) ? ((LinkedList) cuS.vST.vTU.get(ctS)).size() > 0 ? d.CTRL_INDEX : i2 : i2;
        l iVar = new i(cuB, str, hC, i3, this.yXJ.ejx.cuS().fu(ctS, str));
        q qVar2 = this.yXJ.yRE;
        if (qVar2.ejx.cuC()) {
            aw awVar;
            cuB = qVar2.klH;
            ax SB = com.tencent.mm.bb.d.SB();
            String wG = qVar2.ejx.wG();
            Cursor b = SB.fOK.b("SELECT * FROM " + SB.getTableName() + " where sayhiencryptuser=? and isSend=0 and flag=0" + " ORDER BY createtime desc LIMIT 1", new String[]{wG}, 2);
            if (b == null) {
                awVar = null;
            } else if (b.moveToFirst()) {
                awVar = new aw();
                awVar.c(b);
                b.close();
            } else {
                b.close();
                awVar = null;
            }
            if (!(awVar == null || bh.oB(awVar.field_ticket))) {
                cuB = awVar.field_ticket;
            }
            if (bh.oB(cuB)) {
                awVar = com.tencent.mm.bb.d.SB().YM(qVar2.ejx.wG());
                if (!(awVar == null || bh.oB(awVar.field_ticket))) {
                    cuB = awVar.field_ticket;
                }
            }
            if (cuB != null) {
                iVar.gJj = new h(cuB);
            }
        }
        au.Dv().a(iVar, 0);
        if (s.hy(ctS)) {
            au.Dv().a(new com.tencent.mm.plugin.setting.model.i(com.tencent.mm.compatible.e.q.zI(), this.fNk + " key " + bj.cnt() + " local key " + bj.cns() + "NetType:" + an.getNetTypeString(this.yXJ.ejx.cuH().getContext().getApplicationContext()) + " hasNeon: " + n.zj() + " isArmv6: " + n.zl() + " isArmv7: " + n.zk()), 0);
        }
    }
}

这个类就是 消息处理的过程 调用关键方法
au.Dv().a(l lVar, int i)

我在分析到这个地方被卡了很久

这个au.Dv().a(l lVar, int i) 有三种形式

以下面的方式调用可以实现自动回复，自能自己看到，对方看不到消息

au.Dv().a(new a(this.yXJ.ejx.cuz().field_username, this.fNk), 0);

以下面的方式调用可以实现自动回复，自能自己看到，对方也能看到消息

       l iVar = new i(cuB, str, hC, i3, this.yXJ.ejx.cuS().fu(ctS, str));
       
au.Dv().a(iVar, 0);

以下面的方式暂未试验，有兴趣的小伙伴可以自己尝试调用，如果方便的话可以以反馈给我

            au.Dv().a(new com.tencent.mm.plugin.setting.model.i(com.tencent.mm.compatible.e.q.zI(), this.fNk + " key " + bj.cnt() + " local key " + bj.cns() + "NetType:" + an.getNetTypeString(this.yXJ.ejx.cuH().getContext().getApplicationContext()) + " hasNeon: " + n.zj() + " isArmv6: " + n.zl() + " isArmv7: " + n.zk()), 0);

接下来就是给上面的方法拼接参数，等会给的代码里面会提到。这里就不多重复了

到此我们能够回复了，那么我们回复的时机是什么呢？
于是我们需要找到什么时候收到消息，然后进行调用上面的代码

重复DDMS的操作进行接收消息通知的筛选 如下图

QQ截图20180612232854.png

看到筛选后关键类com.tencent.mm.booter.notification.b$1

package com.tencent.mm.booter.notification;

import android.os.Looper;
import android.os.Message;
import com.tencent.mm.sdk.platformtools.ac;
import com.tencent.mm.sdk.platformtools.af;
import com.tencent.mm.sdk.platformtools.w;

class b$1 extends af {
    final /* synthetic */ b fEw;

    b$1(b bVar, Looper looper) {
        this.fEw = bVar;
        super(looper);
    }

    public final void handleMessage(Message message) {
        super.handleMessage(message);
        ac.getContext().getSharedPreferences("notify_prep", 0).edit().putBoolean("longNoopIntervalFlag", true).apply();
        String string = message.getData().getString("notification.show.talker");
        String string2 = message.getData().getString("notification.show.message.content");
        int i = message.getData().getInt("notification.show.message.type");
        int i2 = message.getData().getInt("notification.show.tipsflag");
        w.i("MicroMsg.MMNotification", "notify need to deal: %s", new Object[]{string});
        try {
            if (message.what == 1) {
                b.a(this.fEw, string, string2, i, i2, true);
            } else {
                b.a(this.fEw, string, string2, i, i2, false);
            }
        } catch (Throwable e) {
            w.printErrStackTrace("MicroMsg.MMNotification", e, "showNotifiHandler", new Object[0]);
        }
    }
}

看着这关键字貌似挺匹配的，于是进行hook发现确实接收的时候会执行这里

结合上面的得到如下代码

@Override
    public void autoRepeat() {

        final Class afClass = XposedHelpers.findClass("com.tencent.mm.sdk.platformtools.af", mClassLoader);
//        //获取收到消息的标记通知栏
        Class b$1Class = XposedHelpers.findClass("com.tencent.mm.booter.notification.b$1", mClassLoader);
        XposedHelpers.findAndHookMethod(b$1Class, "handleMessage", Message.class, new XC_MethodHook() {
            @Override
            protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
                super.beforeHookedMethod(param);
                Message message = (Message) param.args[0];
                final String string = message.getData().getString("notification.show.talker");
                String string2 = message.getData().getString("notification.show.message.content");
                int i = message.getData().getInt("notification.show.message.type");
                int i2 = message.getData().getInt("notification.show.tipsflag");
                LogUtils.i(string, string2, i, i2, afClass);
                Class gClass = XposedHelpers.findClass("com.tencent.mm.kernel.g", mClassLoader);
                Object g = XposedHelpers.callStaticMethod(gClass, "Ea");
                Object filedA = XposedHelpers.getObjectField(g, "fVR");

                Class oClass = XposedHelpers.findClass("com.tencent.mm.ac.o", mClassLoader);
                Class lClass = XposedHelpers.findClass("com.tencent.mm.ac.l", mClassLoader);
                Method methodA = XposedHelpers.findMethodExact(oClass, "a", lClass, int.class);
                Object o = XposedHelpers.callStaticMethod(oClass, "a", filedA);

                //这里只能自己看到回复消息 对方看不到
//                Class aClass = XposedHelpers.findClass("com.tencent.mm.ai.a", mClassLoader);
//                Object a = XposedHelpers.newInstance(aClass, new Class[]{String.class, String.class}, string, "haha");
//                Object[] p = new Object[]{a, 0};

                //调用这里可以实现自动回复 并发送到对方
                Class iClass = XposedHelpers.findClass("com.tencent.mm.modelmulti.i", mClassLoader);
                Object io = XposedHelpers.newInstance(iClass, new Class[]{String.class, String.class, int.class, int.class, Object.class}, string, "haha", 1, 1, new HashMap() {{
                    put(string, string);
                }});
                Object[] pp = new Object[]{io, 0};
//                LogUtils.i(gClass, g, filedA, oClass, lClass, methodA, o, aClass, a, p, iClass, io, pp);
                LogUtils.i(gClass, g, filedA, oClass, lClass, methodA, o, iClass, io, pp);
                try {
//                    XposedBridge.invokeOriginalMethod(methodA, o, p);

                    XposedBridge.invokeOriginalMethod(methodA, o, pp);
                } catch (Exception e) {
                    e.printStackTrace();
                    LogUtils.e(e.getLocalizedMessage());
                }
                LogUtils.i("send ok");
            }
        });

    }

令我感到头痛的是在进行匹配参数，因为有些关联的引用不是很明显，找的时候有很多误区。
根据以上内容今后可以扩展聊天机器人，群助手，以及方便学习微信抢红包的流程。哈哈

以上为本课内容，我所有的内容都是以学习为主，请各位小伙伴勿要用来违法，造成的一切违法后果与本人无任何关系
