Python 脚本如下：操作微信登录键

from appium import webdriver
import time
desired_caps = {}
# 获取操作平台
desired_caps['platformName'] = 'Android'
#desired_caps['platformVersion'] = '4.4.2'
# 获取设备名
desired_caps['deviceName'] = '127.0.0.1:62001'
# 获取包名
desired_caps['appPackage'] = 'com.tencent.mm'
# 获取活动名
desired_caps['appActivity'] = '.plugin.account.ui.WelcomeActivity'

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

try:

com.tencent.mm:id/f34 为通过 uiautomatorviewer 截取微信界面获取到的登录键

element = driver.find_element_by_id('com.tencent.mm:id/f34')
# 如果找到该 id 所指定控件，则进行点击操作
element.click()
except:
print "exist"
pass
time.sleep(2)
# 断开连接
driver.quit()

报错信息如下：
