移动端爬虫--单设备自动化（二）

单设备自动化

• 准备

  假设软件环境都已配置

  一台android虚拟机， 我的是夜神端口是62025

• 启动

  1. 连接设备

  2. 运行appium，默认启动4723端口

  备注：

  ​ 1） 设备提前装好app， appActivity和appPackage的值下面介绍

  ​ 2）deviceName： 如果是真机，填设备的型号（如我的华为畅享7： SLA-LA00）

  3. 审查元素

     [图片上传失败...(image-cc0a5d-1532398731012)]

     上图已经标记出了appPackage，至于appActivity指的是android app的入口activity组件，默认是MainActivity，可以通过反编译工（AndroidKiller）具查看。

  4. capability设置

     {
       "platformName": "Android",
       "automationName": "Appium",
       "platformVersion": "5.1.1",
       "appPackage": "com.ss.android.ugc.aweme",
       "appActivity": "com.ss.android.ugc.aweme.main.MainActivity",
       "noReset": "True",
       "deviceName": "Emulator"
     }
     

到此appium操控app成功。下面给出一段代码，使用python操控

# the emulator is sometimes slow and needs time to think
SLEEPY_TIME = 1
