文章的主要思路来自于 seveniruby 的Appium 微信 webview 的自动化技术,非常感谢~~
通过微信打开 debugx5.qq.com,或者直接扫下面二维码
勾选【打开 TBS 内核 Inspector 调试功能】
手机连接电脑,查看是否连接成功。如下展示设备号则为连接成功
进入任意小程序,以【X 东】为例,在 Chrome 浏览器访问 chrome://inspect/#devices
点击 inspact,即可查看页面元素
微信有很多的进程,每一个小程序都运行在不同的进程中。
进入【X 东】后,看下当前运行在哪个进程中
我们可以看到,当前的小程序运行在 com.tencent.mm:appbrand0 中,记住这个进程,记住啦
最关键的一点,需要添加 androidProcess 这一项,也就是我们上面的 com.tencent.mm:appbrand0
我用 python 写一个简单的 demo
desired_caps = {
'platformName': 'Android',
'fastReset': 'false',
'deviceName': 'XXXXXX',
'appPackage': 'com.tencent.mm',
'appActivity': '.ui.LauncherUI',
'fullReset': 'false',
'unicodeKeyboard': 'True',
'resetKeyboard': 'True',
'chromeOptions': {
'androidProcess': 'com.tencent.mm:appbrand0'
}
}
driver = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps)
driver.find_element_by_name("发现").click()
driver.find_element_by_name("小程序").click()
driver.find_element_by_name("X东购物").click()
driver.switch_to.context('WEBVIEW_com.tencent.mm:appbrand0')
time.sleep(5)
print(driver.page_source)
我遇到过一种切换 Webview 失败的情况,下面贴上 appium 的报错日志。

注意最后那一段的 chrome 和 chromedriver 的版本
查看对应表可知,两者版本不对应,需要替换 chromedriver
将 Appium 的 chromedriver 替换为相应版本后,即可成功切换。
