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

View Code

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。

大家不要留言说我简单事情做那么复杂。用物理方式（现在回头看倒觉得很像单元测试）实现回复，真实性是100%，发贴机你要倒腾一个别人家服务器看不出作弊的，估计更费劲吧。

如果你觉得python写脚本很酷或者直接用fiddler抓包然后写个发帖器都行。我这还有个用Tesseract-OCR做验证码识别的winform。

做这个只是当时觉得红包插件原理很酷，可以有点其他玩法，我也确实倒腾了一个，也开源了https://github.com/huijimuhe/focus

要是开开脑洞，比如不停的微信给欠债老板发消息让还钱啥的，这种插件倒是很能气死他，哈哈哈哈。

要搞什么推广（尤其是卖面膜的）应该靠金主，而不是这个，哈哈哈哈。
