Webdriverio touchAction与touchPerform API未实现报错求助

环境配置 #

• uiautomator2版本：2.35.0
• Appium版本：2.3.0
• Webdriverio版本：8.15.0
• Node版本：16.18.0

报错代码 #

1. touchAction API #

browser.touchAction([
    { action: "press", x: xStart, y: yStart },
    { action: "wait", ms: speed },
    { action: "moveTo", x: xFinish, y: yFinsh },
    { action: "release" }
])

2. touchPerform API #

browser.touchPerform([
    { action: "press", options: { x: xStart, y: yStart } },
    { action: "wait", options: { ms: speed } },
    { action: "moveTo", options: { x: xFinish, y: yFinsh } },
    { action: "release", options: {} }
])

解决方案 #

原因 #

Appium 2.x搭配uiautomator2 2.35.0时，旧的touchAction/touchPerform API已被移除，这些属于Appium 1.x的遗留接口，当前uiautomator2驱动不再支持，需改用W3C标准的Actions API。

替代实现代码 #

使用Webdriverio 8.x支持的Actions API实现滑动操作：

// 实现从(xStart,yStart)滑动到(xFinish,yFinsh)的触摸操作
const actions = await browser.action('pointer');
await actions
  .pointerMove({ x: xStart, y: yStart }) // 移动到起始点
  .pointerDown({ button: 0 }) // 按下（模拟触摸按下）
  .pause(speed) // 等待指定时长
  .pointerMove({ x: xFinish, y: yFinsh }) // 滑动到终点
  .pointerUp({ button: 0 }) // 松开（模拟触摸抬起）
  .perform(); // 执行操作

其他注意事项 #

• 若必须使用旧API，可尝试回退uiautomator2驱动到2.34.0版本，但不推荐，因为旧版本可能存在兼容性或安全问题
• Webdriverio 8.x完全兼容W3C Actions API，这是当前移动端自动化触摸操作的标准方案，建议优先采用
