验证码滑块处理：移动元素指定偏移量后报错

霍格沃兹答疑区
1

【问题描述】登录模块有个需要滑块验证码，如图所示（filesystem:https://vanish.myhexin.com/persistent/1005772/1620478365649-screenshots.png），目前已经算出需要滑动的偏移量，想用Touchaction方法去进行移动，但一直报错：
代码如下：

           print(f'需要移动的距离是:{top_left}')
        if self.driver.find_element(By.CSS_SELECTOR,'#drag-icon'):
            move_elem = self.driver.find_element(By.CSS_SELECTOR,'#drag-icon')
            #location = move_elem.location
            # size = move_elem.size
            #print(f'location是:{location}')
            #print(f'size:{size}')
            action = TouchAction(self.driver)
            # action.flick_element(move_elem, top_left, 0, 50).perform()
            action.press(move_elem).wait(200).move_to(x=top_left,y=0).release().perform()

错误信息如下：

问题2：本来是想通过获取这个元素的location去进行移动，但也报错不行：

希望老师和同学帮忙看下

2

是在哪一行开始报错的呢

3

你好 ，
问题1是在 action.press(move_elem).wait(200).move_to(x=top_left,y=0).release().perform()报错的；
问题2是在 location = move_elem.location 报错的；

4

你这个是webview？是的话看下是否是没切换context成功

5

整个登录页就是H5，已经切换了context，代码我没贴出来；
或者你的意思是，显示这个滑块验证码后还需要再切换一次context？？？

6

对，可以打印下context看看是不是换了个，一般来说如果定位符没错的话就是没切换导致的

7

你好，打印了下context确定不需要再，目前已经解决了问题1的报错，需要加上参数 desired_caps[‘chromeOptions’] = {‘w3c’: False}
