java下使用chromedriver获取访问页面状态码

##在使用chromedriver的时候 并没有提供api来获取访问页面的状态码，但是可以打开日志来获取到

    LoggingPreferences logPrefs = new LoggingPreferences();
        logPrefs.enable(LogType.PERFORMANCE, Level.ALL);
        DesiredCapabilities cap = DesiredCapabilities.chrome();
        cap.setCapability(CapabilityType.LOGGING_PREFS, logPrefs);

全部代码如下：

    ChromeOptions options = new ChromeOptions();
        LoggingPreferences logPrefs = new LoggingPreferences();
        logPrefs.enable(LogType.PERFORMANCE, Level.ALL);
        DesiredCapabilities cap = DesiredCapabilities.chrome();
        cap.setCapability(CapabilityType.LOGGING_PREFS, logPrefs);
        options.addArguments("headless");
        //禁用沙盒nage
        options.addArguments("no-sandbox");
        options.addArguments("disable-gpu");
        cap.setCapability(ChromeOptions.CAPABILITY, options);
        ChromeDriver driver = new ChromeDriver(cap);
        driver.get("https://www.baidu.com");
        String currentURL = driver.getCurrentUrl();
        LogEntries logs = driver.manage().logs().get("performance");
        int status = -1;
        System.out.println("
List of log entries:
");
        for (Iterator<LogEntry> it = logs.iterator(); it.hasNext(); ) {
            LogEntry entry = it.next();
            try {
                JSONObject json = JSON.parseObject(entry.getMessage());
                System.out.println(json.toString());
                JSONObject message = json.getJSONObject("message");
                String method = message.getString("method");
                if (method != null&& "Network.responseReceived".equals(method)) {
                    JSONObject params = message.getJSONObject("params");
                    JSONObject response = params.getJSONObject("response");
                    String messageUrl = response.getString("url");
                    if (currentURL.equals(messageUrl)) {
                        status = response.getInteger("status");
                        System.out.println("---------- bingo !!!!!!!!!!!!!! returned response for "+ messageUrl + ": " + status);
                        System.out.println("---------- bingo !!!!!!!!!!!!!! headers: "+ response.get("headers"));
                    }
                }
            } catch (JSONException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
        System.out.println("
status code: " + status);
