Appium：从渲染器接收消息超时：10.000 在 Browserstack 中获取旧设备的屏幕截图

编程问答 2022-04-23

问题描述

我正在研究 Web 应用程序的自动化，我需要获取屏幕截图以处理页面上的画布元素。我在 browserstack 中执行此操作，它适用于现代设备（即三星 galaxy S21），但有时会在某些旧设备（即三星 galaxy S7）上失败。

我使用以下方法制作屏幕截图：

driver.get_screenshot_as_png()

然后我收到错误：

Timed out receiving message from renderer: 10.000

是否可以增加此超时？或任何其他解决我问题的建议。

附言我尝试使用 driver.set_script_timeout 和 driver.set_page_load_timeout 增加超时时间，但对我没有效果。

我的配置：

Appium-Python-Client==1.1.0
