app抓包

环境搭建

Android模拟器安装

image


官网下载夜神模拟器安装

抓包工具安装

image

appium安装

https://github.com/appium/appium-desktop/releases/tag/v1.11.0

mitmproxy安装

下载安装包, 直接点击下一步即可安装
https://github.com/mitmproxy/mitmproxy/releases/

装好之后配置一下环境变量就行了

也可以直接使用pip install mitmproxy

安装证书

在cmd中输入mitmdump, 可以看到mitmdump已经启动了, 在监听8080端口

C:\Users\IIce>mitmdump
Proxy server listening at http://*:8080

打开模拟器, 配置代理

查看一下pc的ip

以太网适配器 以太网:

   连接特定的 DNS 后缀 . . . . . . . : North-Class.com
   本地链接 IPv6 地址. . . . . . . . : fe80::68d7:38a8:2729:4d97%6
   IPv4 地址 . . . . . . . . . . . . : 192.168.100.243
   子网掩码  . . . . . . . . . . . . : 255.255.255.0
   默认网关. . . . . . . . . . . . . : 192.168.100.250
image

配置好以后, 打开浏览器, 输入baidu.com进行查看
此时会弹出证书问题, 点继续即可

输入mitm.it
选择相应的版本进行安装

image

image

此时再访问网站就不会有证书问题了

docker安装

根据配置, 二选一

docker-toolbox

https://docs.docker.com/toolbox/toolbox_install_windows/
下载docker-toolbox, 双击进行安装即可

如果安装快要结束时报错
IPersistFile：Save 失败，代码0x80070005 拒绝访问
需要检查杀毒软件

安装成功后会出现三个图标


image

双击Docker Quickstart Terminal图标，启动一个终端
会下载一个boot2docker.iso文件,如果下载较慢的话,可以复制链接自行下载,
下载完成后复制到目录中即可


image

如果出现Unable to start the VM: C:\Program Files\Oracle\VirtualBox\VBoxManage.exe startvm default --type headless failed:卸载掉Oracle VM Virtualbox安装最新版即可
https://www.virtualbox.org/wiki/Downloads

完成后会出现

image

输入docker run hello-world
image

Docker for Windows

https://docs.docker.com/docker-for-windows/install/

下载后双击安装即可

如果安装卡顿, 需要检查杀毒软件, 因为会修改注册表和启动项等

启动时如果报错
“Hardware assisted virtualization and data execution protection must be enabled in the BIOS”

需要开启虚拟化和Hyper-V

如果都开启还如法启动
参考https://www.e-learn.cn/content/wangluowenzhang/589447

将adb.exe复制一份,覆盖掉原来的nox_adb.exe,
开启模拟器的开发者选项
重启模拟器,打开cmd

Appium会先打开抖音, 然后点击搜索图标, 获取搜索栏进行输入, 点击搜索按钮, 点击用户, 点击头像, 点击粉丝, 模拟滑动, 直到没有粉丝了

粉丝入库

使用mitmdump来将数据存入数据库
mitmdump -s xxx.py

import json

from douyin.handle_mongo import save_task


def response(flow):
    if 'aweme/v1/user/follower/list/' in flow.request.url:
        for user in json.loads(flow.response.text)['followers']:
            douyin_info = {}
            douyin_info['share_id'] = user['uid']
            douyin_info['douyin_id'] = user['short_id']
            douyin_info['nickname'] = user['nickname']
            save_task(douyin_info)

这样在滑动粉丝时, 就会将粉丝的信息添加进数据库

多设备抓取

设置一下appium
appium客户端设置 udid
appium服务端设置 bootstrapPort

https://www.iesdouyin.com/web/api/v2/aweme/post/?
user_id=58862693224 #   分享链接中的id
count=21            #   视频个数

aid=1128            #   固定值
_signature=laPLvBAVyX-c77Gpje7Ys5Wjy6   #   签名值，由签名算法计算
dytk=66cb5d220e0e48ed9195a7f62ac32764   #   不知道是啥, 网页中可直接提取

获取签名算法

打开控制台, 搜索_signature

image

定位_bytedAcrawler

image

定位 douyin_falcon:node_modules/byted-acrawler/dist/runtime

image

定位 __M.define

image

分析签名算法的执行逻辑

① 定义 __M对象，及其define 和require 函数
② 执行 __M.define("douyin_falcon:node_modules/byted-acrawler/dist/runtime......" 这段代码
③ 执行_bytedAcrawler = require("douyin_falcon:node_modules/byted-acrawler/dist/runtime")

④ 计算签名值 _signature = _bytedAcrawler.sign(user_id)

我们可以自己编写一个html文件, 访问这个文件来得到_signature

关于水印

视频链接的url分两种

  1. https://aweme.snssdk.com/aweme/v1/play/?video_id=v0300f6d0000bj81rdqrh6f3j18kvnpg&line=0&ratio=540p&media_type=4&vr_type=0&improve_bitrate=0
  2. https://aweme.snssdk.com/aweme/v1/playwm/?video_id=v0300f6d0000bj81rdqrh6f3j18kvnpg&line=0&ratio=540p&media_type=4&vr_type=0&improve_bitrate=0

区别:

  1. 第一个请求的是play,第二个请求的是playwm
  2. 第一个网站是打不开的, 第二个可以打开
  3. 都可以使用requests来获取
  4. 第一个是无水印的!!!

通过Postman测试, 发现只保留一个video_id即可

image

参数说明

image

has_more来判断是否需要翻页
max_cursor下次请求时需要携带的, 首次为 0

参考

使用 NodeJS 提供抖音签名算法服务
