使用 selenium 遠程驅動程序捕獲網絡流量

Question

我正在嘗試使用 selenium 遠程驅動程序捕獲網絡流量，但面臨以下問題。

Exception in thread "main" org.openqa.selenium.InvalidArgumentException: invalid argument: log type 'performance' not found

Chrome 在 75+ 版本中更改了日志記錄的工作方式。 由於 ChromeDriver 現在默認在 W3C 標准兼容模式下運行，因此更改破壞了以下內容。

capabilities.setCapability(CapabilityType.LOGGING_PREFS, logPrefs);

因此，根據 W3C 標准的要求，chromedriver 的部分更改是將功能“loggingPrefs”重命名為“goog:loggingPrefs”。 這打破了我們為 Chrome 瀏覽器設置 Selenium 3.141.59 功能的方式。 這已在 Selenium 4.0.0 版中得到修復。

有 2 個選項，遷移到 Selenium 4.0.0 或暫時使用以下解決方法之一：

options.setCapability("goog:loggingPrefs", logPrefs);

capabilities.setCapability("goog:loggingPrefs", logPrefs);

如果您確實遷移到 Selenium 4，請注意選項已取代功能，現在將是：

options.setCapability(CapabilityType.LOGGING_PREFS, logPrefs);
