昨天小帅b看到一些事情不顺眼
有人偷换概念
忍不住就写了一篇反讽 996 的
看不下去了，我支持996，年轻人就该996！
没想到有些人看不懂
这就算了
还来骂我
早些时候关注我的小伙伴应该知道我第一时间就发过反对 996 的文章
去他妈的996！
python之父就是牛逼
哎～
不过也好
洗掉一些无脑假粉丝
“你个假粉丝，小帅b不是蔡徐坤”
好了
进入正题
上次
小帅b跟你说了如何安装 Appium 的相关环境
以及让它自动打开了手机上的微信App
python爬虫23 | 手机，这次要让你上来自己动了。这就是 Appium+Python 的牛x之处
相信你已经跃跃欲试
想要来爬取一些手机上的 APP 数据了
那么这次
小帅b就带你爬取微信朋友圈的数据
接下来就是
学习 python 的正确姿势
友情提醒
本篇需要你先安装好 Appium 相关环境才可以哟，如果你还没安装的话快点出门左转，安装完之后再来这里玩耍。
ok
首先我们要知道微信这个 apk 的包名和启动页的 Activity
将你的 Android 鸡连接到电脑
在终端输入 adb devices 确保你已经将你的鸡连接到电脑
如果像上面这样出现设备名称就说明你连接上你的电脑了
如果你插进电脑之后还没发现有任何设备名称显示
那就记得打开 USB 调试，多拔插几次，总会连上的，这是过来人经验
接着
在你的手机里面打开微信
然后打开你的终端输入
adb shell然后输入
dumpsys activity | grep mFocusedActivity这时候我们就获取到微信的包名和启动页面的名称了
我们还要知道我们的手机是什么版本的
输入以下命令获取
adb shell getprop ro.build.version.release那么现在我们就知道了这些必要的信息了
desired_caps = {}desired_caps['platformName'] = 'Android'desired_caps['platformVersion'] = '5.1'desired_caps['deviceName'] = '88CKBM622PAM'desired_caps['appPackage'] = 'com.tencent.mm'desired_caps['appActivity'] = '.ui.LauncherUI'
接下来
主要思路就是
自动开启微信
模拟登录微信
找到小帅b的朋友圈
把朋友圈的数据抓下来
想要模拟登录
我们就需要获取到微信的登录按钮这个元素
如何获取呢？
在你安装好的 sdkmanager 的 tool 目录下
有一个叫做 uiautomatorviewer 的工具
windows用户直接双击打开
ubuntu的话可以进入相应的目录
用命令 ./uiautomatorviewer 行打开
~/android/tools/bin$ ./uiautomatorviewer 打开之后是这个鸟样
我们点击菜单栏的第二个图标按钮
这时候你就会发现
手机的屏幕被抓过来了
用鼠标点一下登录按钮你会看到
相应的资源信息都被定位到了
那么要让它自动点击登录按钮就简单了
# 获取到登录按钮后点击login_btn = self.wait.until(EC.element_to_be_clickable((By.ID, "com.tencent.mm:id/e4g")))login_btn.click()
点击登录之后页面是这样的
我们要切换到用邮箱登录
还是老样子
我们获取到按钮，然后让它点击
# 获取使用微信号登录按钮change_login_btn = self.wait.until(EC.element_to_be_clickable((By.ID, "com.tencent.mm:id/cou")))change_login_btn.click()
那么接下来就输入账号密码了
恩
获取到账号和密码的 EditText 和 登录按钮
然后自动输入账号密码
最后点一下登录
# 获取输入账号元素并输入account = self.wait.until(EC.presence_of_element_located((By.XPATH, '//*[@resource-id="com.tencent.mm:id/cos"]/android.widget.EditText')))account.send_keys("你的微信账号")# 获取密码元素并输入password = self.wait.until(EC.presence_of_element_located((By.XPATH, '//*[@resource-id="com.tencent.mm:id/cot"]/android.widget.EditText')))password.send_keys("你的微信密码")# 登录login = self.wait.until(EC.element_to_be_clickable((By.ID, "com.tencent.mm:id/cov")))login.click()
登录之后会弹出一个界面
你愿意把你的通讯录授权给我吗？
呵呵
no！
# 点击去掉通讯录提示框no_btn = self.wait.until(EC.element_to_be_clickable((By.ID, "com.tencent.mm:id/az9")))no_btn.click()
这样
我们就成功登入微信了
接下来找到小帅b的微信
需要点击上方的搜索按钮
# 获取到搜索按钮后点击search_btn = self.wait.until(EC.element_to_be_clickable((By.ID, "com.tencent.mm:id/iq")))search_btn.click()
这时候会出现输入框
搜索小帅b本b
# 获取搜索框并输入search_input = self.wait.until(EC.presence_of_element_located((By.ID, "com.tencent.mm:id/kh")))search_input.send_keys("wistbean")
这时候会出现一个 item
没错
点击头像进去
# 点击头像进入xiaoshuaib_btn = self.wait.until(EC.element_to_be_clickable((By.ID, "com.tencent.mm:id/py")))xiaoshuaib_btn.click()
接下来几步都是一个道理
主要是进入小帅b的朋友圈
# 点击右上角...进入menu_btn = self.wait.until(EC.element_to_be_clickable((By.ID, "com.tencent.mm:id/jy")))menu_btn.click()# 再点击头像icon_btn = self.wait.until(EC.element_to_be_clickable((By.ID, "com.tencent.mm:id/e0c")))icon_btn.click()# 点击朋友圈moment_btn = self.wait.until(EC.element_to_be_clickable((By.ID, "com.tencent.mm:id/d86")))moment_btn.click()
就这样点进去
进入朋友圈之后
我们来分析一下
可以看到小帅b的朋友圈是这样的
我们需要滑动获取到更多内容
可以使用 Appium 的 swipe 方法
再来
我们需要循环获取到数据
可以看到每条朋友圈都被封装到 ListView 这个容器里面
所以我们要从这里面获取所有数据
然后再进行遍历
那么每一个具体的条目呢？
可以看到
数据被放在了 LinearLayout 的具体容器里面了
所以我们可以根据 id 获取相应的内容
# 获取 FrameLayoutitems = self.wait.until(EC.presence_of_all_elements_located((By.ID, 'com.tencent.mm:id/eew')))# 滑动self.driver.swipe(self.start_x, self.start_y, self.end_x, self.end_y, 2000)#遍历获取for item in items:moment_text = item.find_element_by_id('com.tencent.mm:id/kt').textday_text = item.find_element_by_id('com.tencent.mm:id/eke').textmonth_text = item.find_element_by_id('com.tencent.mm:id/ekf').textprint('抓取到小帅b朋友圈数据： %s' % moment_text)print('抓取到小帅b发布时间： %s月%s' % (month_text, day_text))
至此
我们的代码写完了
来运行一下吧
首先打开 Appium
[Appium] Welcome to Appium v1.12.1[Appium] Appium REST http interface listener started on 0.0.0.0:4723
接着运行爬取朋友圈的代码
截取部分结果
微信启动...登录成功...搜索小帅b...进入朋友圈...抓取到小帅b朋友圈数据： 那天马云说：我从来没碰过钱，我对钱没兴趣。最近马云说：能 996 是一种福气，我每天都 1212。果然，有钱爸爸说话就是好听。抓取到小帅b发布时间： 4月月12抓取到小帅b朋友圈数据： 有本事双击我头像抓取到小帅b发布时间： 4月月10抓取到小帅b朋友圈数据： 刚点了外卖，小哥有点超时才送到。我倒不觉得有什么，可是小哥将餐物双手递给我后接下来的动作让我惊讶到了：他对我深深地鞠了一躬……python爬虫24 | 搞事情了，用 Appium 爬取你的微信朋友圈。的相关教程结束。
