針對appium的webdriver執行swipe無效的解決辦法

self.driver.swipe(x1,y1,x2,y1,t)

　　

當時代碼里有如上這么一句，當時源碼是這么說的：

 

# convenience method added to Appium (NOT Selenium 3)
    def swipe(self, start_x, start_y, end_x, end_y, duration=None):
        """Swipe from one point to another point, for an optional duration.

        :Args:
         - start_x - x-coordinate at which to start
         - start_y - y-coordinate at which to start
         - end_x - x-coordinate at which to stop
         - end_y - y-coordinate at which to stop
         - duration - (optional) time to take the swipe, in ms.

        :Usage:
            driver.swipe(100, 100, 100, 400)
        """

由於例子里也沒有對最后一個參數進行舉例說明，所以我一開始使用的參數為2.后來發現代碼執行后並沒有實現滑動的效果，后來baidu后有人提示說最后一個數字改為100或200.

最終問題解決。最后一個參數的作用應該是在多少毫秒內進行滑動操作。
