1.通过微信打开debugx5.qq.com, 打开调试模式

2.接usb, google浏览器输入 chrome://inspect/#devices

3. 77.0是该微信使用的webveiw内核版本，我们要去下载对应的内核驱动 chromedriver 77。打开https://npm.taobao.org/mirrors/chromedriver， 下载77版本win32。

4. python 添加配置 'chromedriverExecutableDir':r"C:\Users\admin\Downloads\chromedriver_win32" (chromedriver的目录）

5. cmd输入 adb shell dumpsys activity top | findstr ACTIVITY，找出webview的pid 25156

6. cmd输入 adb shell ps 25156

7.python配置加上 'chromeOptions': {'androidProcess': 'com.tencent.mm:toolsmp'}

8. 然后print(driver.contexts)找到context, driver.switch_to.context('WEBVIEW_com.tencent.mm:toolsmp')

例子：

from appium import webdriver

from time import sleep

desired_caps = {

                'platformName': 'Android',

                'platformVersion': '10.0.0',

                'deviceName': 'ANA_AN00',

                'appPackage': 'com.tencent.mm',

                'appActivity': '.ui.LauncherUI',

                'unicodeKeyboard': True,

                'resetKeyboard': True,

                'noReset': True,

                'browserName': '',

                'chromedriverExecutableDir':r"C:\Users\admin\Downloads\chromedriver_win32",

                'chromeOptions': {'androidProcess': 'com.tencent.mm:toolsmp'}

                }

driver = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps)

sleep(2)

driver.find_element_by_id('com.tencent.mm:id/f8y').click()

sleep(2)

driver.find_element_by_android_uiautomator('new UiSelector().text("搜索")').set_text('xxx服务号')

sleep(2)

driver.find_element_by_xpath('//*[@resource-id="com.tencent.mm:id/gbv"]').click()

sleep(2)

driver.find_element_by_android_uiautomator('new UiSelector().text("个人中心")').click()

sleep(2)

driver.find_element_by_android_uiautomator('new UiSelector().text("我的奖励")').click()

sleep(2)

print(driver.contexts)

driver.switch_to.context('WEBVIEW_com.tencent.mm:toolsmp')

sleep(2)

driver.find_element_by_xpath('//p[@class="change-login"]').click()
