基于微信红包插件的原理实现android任何APP自动发送评论（已开源）

背景

地址：https://github.com/huijimuhe/postman

核心就是android的AccessibilityService，回复功能api需要23以上版本才行。

其实很像在做单元测试。你可以有n种方式实现发帖功能，这只是一个比较邪火的方式，亲测过一次，可行。这里我以网易新闻客户端举例。

模拟你在手机端的物理动作：选择新闻-》回复-》退回新闻列表-》进入下一个新闻-》回复-》退回新闻列表刷新-》进入-》回复....

做的不精细，只是探究到底可不可行。你可以用在任何APP中自动发消息，只要没有验证码。

你要拿来玩，请抱着一颗开心的心情。

原理

直接在github上开源的微信红包插件改的，红包插件项目和你需要了解的几篇文章在这里

                        public void run() {
                            mReadCount = 0;
                            enterDetailAct();
                        }
                    }, 3000);
                    break;
                //进入新闻页
                case MSG_READ_NEWS:
                    new Handler().postDelayed(new Runnable() {
                        @Override
                        public void run() {
                            enterDetailAct();
                        }
                    }, 3000);
                    break;
                //发送评论
                case MSG_POST_COMMENT:
                    new Handler().postDelayed(new Runnable() {
                        @Override
                        public void run() {
                            postComment();
                        }
                    }, 3000);
                    break;
            }
        }
    }
}

在开始写代码前，你应该至少阅读了之前几篇文章和微信红包插件的代码，然后还应该掌握用Android Device Monitor查看UI树的工具使用。（最近开始研究iOS逆向，这个确实比reveal和cycript方便太多）

粗略实现步骤

1.manifest中申明服务

 <service
                android:name=".services.PostService"
                android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE">
            <intent-filter>
                <action android:name="android.accessibilityservice.AccessibilityService"/>
            </intent-filter>
            <meta-data android:name="android.accessibilityservice"
                       android:resource="@xml/accessible_service_config"/>
        </service>

 2.设定你需要监控的app包名来过滤，在/res/xml/accessible_service_config.xml中

<accessibility-service
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:description="@string/app_description"
    android:accessibilityEventTypes="typeWindowStateChanged|typeWindowContentChanged"
    android:accessibilityFeedbackType="feedbackAllMask"
    android:packageNames="com.netease.newsreader.activity"
    android:notificationTimeout="10"
    android:settingsActivity="com.huijimuhe.pman.activities.SettingsActivity"
    android:accessibilityFlags="flagIncludeNotImportantViews|flagDefault"
    android:canRetrieveWindowContent="true"/>

比如网易的，android:packageNames="com.netease.newsreader.activity"

3.在AccessibleService中实现对事件的监听 

  @Override
    public void onAccessibilityEvent(AccessibilityEvent event) {

        if (sharedPreferences == null) return;

        setCurrentActivityName(event);
        watchMain(event);
        watchBasic(event);
        watchDetail(event);
    }
/**
 * 设置当前页面名称
 *
 * @param event
 */
private void setCurrentActivityName(AccessibilityEvent event) {

    if (event.getEventType() != AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED) {
        return;
    }

    try {
        ComponentName componentName = new ComponentName(event.getPackageName().toString(), event.getClassName().toString());

        getPackageManager().getActivityInfo(componentName, 0);
        currentActivityName = componentName.flattenToShortString();
        Log.d(TAG, "<--pkgName-->" + event.getPackageName().toString());
        Log.d(TAG, "<--className-->" + event.getClassName().toString());
        Log.d(TAG, "<--currentActivityName-->" + currentActivityName);
    } catch (PackageManager.NameNotFoundException e) {
        currentActivityName = MAIN_ACT;
    }
}

4.监控是否是新闻列表，可以设定个页面刷新阀值

  //新闻列表
        if (event.getEventType() == AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED && currentActivityName.contains(MAIN_ACT)) {
            if (mReadCount > 4) {
                //如果读取完了都没有新的就刷新
                Log.d(TAG, "新闻已读取完,需要刷新列表");
                //需要刷新列表了
                mHandler.sendEmptyMessage(MSG_REFRESH_NEW_LIST);
            } else {
                mHandler.sendEmptyMessage(MSG_READ_NEWS);
            }
        }

5.监控是否是新闻详情

    private void watchDetail(AccessibilityEvent event) {
        if (event.getEventType() == AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED && currentActivityName.contains(DETAIL_ACT)) {
            //添加评论
            mHandler.sendEmptyMessage(MSG_POST_COMMENT);
        }
    }

6监控是否广告或其他专题，不做操作

    private void watchBasic(AccessibilityEvent event) {
        if (event.getEventType() == AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED && currentActivityName.contains(BASE_ACT)) {
            Log.d(TAG, "进入非新闻页,即将退出");
            mHandler.sendEmptyMessage(MSG_BACK);
            mHandler.sendEmptyMessage(MSG_BACK);
        }
    }

7.回复评论

    private void postComment() {
        //激活输入框
        List<AccessibilityNodeInfo> nodes = getRootInActiveWindow().findAccessibilityNodeInfosByViewId("com.netease.newsreader.activity:id/mock_reply_edit");
        for (AccessibilityNodeInfo node : nodes) {

            //页面是否加载完成
            if (node == null) return;

            node.performAction(AccessibilityNodeInfo.ACTION_CLICK);
        }

        //输入内容
        List<AccessibilityNodeInfo> editNodes = getRootInActiveWindow().findAccessibilityNodeInfosByViewId("com.netease.newsreader.activity:id/reply_edit");
        for (AccessibilityNodeInfo node : editNodes) {

            //页面是否加载完成
            if (node == null) return;

            Bundle arguments = new Bundle();
            arguments.putCharSequence(AccessibilityNodeInfo.ACTION_ARGUMENT_SET_TEXT_CHARSEQUENCE, "抽烟的人最讨厌了");
            node.performAction(AccessibilityNodeInfo.ACTION_SET_TEXT, arguments);
        }

        //退出
        mHandler.sendEmptyMessage(MSG_FINISH_COMMENT);

        Log.d(TAG, "评论已发表");
    }

总体思路是通过postDelay来实现操作的间隔，其他的请自己阅读代码，我只测试了下思路是否可行就没有继续延伸下去了。
