Selenium获取本地已打开的浏览器页面进行跟踪和自定义日志记录

// 启用性能日志跟踪
            ChromeOptions options = new ChromeOptions();
            LoggingPreferences logPrefs = new LoggingPreferences();
            logPrefs.enable(LogType.PERFORMANCE, Level.ALL);
            Map<String, Object> perfLogPrefs = new HashMap<String, Object>();
            perfLogPrefs.put("traceCategories", "browser,devtools.timeline,devtools");
            options.setExperimentalOption("perfLoggingPrefs", perfLogPrefs);

// 开启浏览器debugger模式（selenium环境基本配置另行学习）
ChromeOptions capabilities = new ChromeOptions();
capabilities.setCapability(ChromeOptions.CAPABILITY, options);
capabilities.setCapability(CapabilityType.LOGGING_PREFS, logPrefs);
capabilities.setExperimentalOption("debuggerAddress", "localhost:9527");

// 日志自定义提取
LogEntries logEntries = driver.manage().logs().get(LogType.PERFORMANCE);
for (LogEntry entry : logEntries) {
    System.out.println(new Date(entry.getTimestamp()) + " " + entry.getLevel() + " ======" + entry.getMessage());
    System.out.println(new Date(entry.getTimestamp()) + " " + entry.getLevel().INFO + "  INFO======== " + entry.getMessage());
    System.out.println(new Date(entry.getTimestamp()) + " " + entry.getLevel().ALL + " ALL ======== " + entry.getMessage());
    System.out.println(new Date(entry.getTimestamp()) + " " + entry.getLevel().SEVERE + " SEVERE ======== " + entry.getMessage());
    System.out.println(new Date(entry.getTimestamp()) + " " + entry.getLevel().WARNING + " WARNING ======== " + entry.getMessage());
    //do something useful with the data
}

本操作只是打基本的核心代码写清楚，基础环境配置和原理
