使用 Selenium、Maven、Browsermob 和 Browserstack 通过 Har 文件提取网络请求

热度：17   发布时间：2023-08-02 10:49:40.0

问题描述

我正在尝试在我们的 selenium 设置中使用 Browsermob 测试我们的分析。

但是，当我运行测试时，我尝试创建的 Har 文件要么根本没有创建，要么其中没有信息可以解析并显示在命令提示符中。

    public static void main() throws InterruptedException, UnknownHostException {

        DesiredCapabilities capability = new DesiredCapabilities();
        Proxy seleniumProxy = ClientUtil.createSeleniumProxy(proxy);
        capability.setCapability(CapabilityType.PROXY, seleniumProxy);
        proxy.setHarCaptureTypes(CaptureType.getAllContentCaptureTypes());
        proxy.enableHarCaptureTypes(CaptureType.getAllContentCaptureTypes());
        proxy.start();
    }

    @BeforeClass(alwaysRun = true)
    public static void setUp() throws InterruptedException, UnknownHostException {

        TestSetup();
        //String session = ((RemoteWebDriver) webDriver.get()).getSessionId().toString();
        //System.out.println(session);

    }

    @Test(groups = { "iFrame" }, priority = 1)

    public void iFrameVerification() throws InterruptedException {

        iFrame();
    }

    @Test(groups = { "Hero Elements" }, priority = 2)

    public void HeroVerification() {
        HeaderVerify();
        DelayIDVerify();
        LogSwitchVerify();
        RewardStickerVerify();
        AklamioLinkVerify();
    }

    @Test(groups = { "How It Works" }, priority = 3)

    public void HIWVerification() {

        HIWVerify();
    }

    @Test(groups = { "Products" }, priority = 4)

    public void ProductVerification() {

        ProductVerify();
    }

    @AfterClass(alwaysRun = true)
    public void TearDown() throws InterruptedException {
        webDriver.get().quit();

    }

    @AfterSuite(alwaysRun = true)
    public void proxyDown() throws InterruptedException {

        proxy.stop();
    }
}

所以当运行所有这些时，它运行良好，但我在控制台中得到一个空的 har 文件。

从性能日志中获取“消息”JSONObject

private static JSONArray getPerfEntryLogs(WebDriver driver) {
    LogEntries logEntries = driver.manage().logs().get(LogType.PERFORMANCE);
    JSONArray perfJsonArray = new JSONArray();
    logEntries.forEach(entry -> {
        JSONObject messageJSON = new JSONObject(entry.getMessage()).getJSONObject("message");
        perfJsonArray.put(messageJSON);
    });
    return perfJsonArray;
}

通过 PerfLogs

public static void getHAR(WebDriver driver, String fileName) throws IOException {
    String destinationFile = "/HARs/" + fileName + ".har";
    ((JavascriptExecutor) driver).executeScript(
            "!function(e,o){e.src=\"https://cdn.jsdelivr.net/gh/Ankit3794/chrome_har_js@master/chromePerfLogsHAR.js\",e.onload=function(){jQuery.noConflict(),console.log(\"jQuery injected\")},document.head.appendChild(e)}(document.createElement(\"script\"));");
    File file = new File(destinationFile);
    file.getParentFile().mkdirs();
    FileWriter harFile = new FileWriter(file);
    harFile.write((String) ((JavascriptExecutor) driver).executeScript(
            "return module.getHarFromMessages(arguments[0])", getPerfEntryLogs(driver).toString()));
    harFile.close();
}

当您执行页面请求时，您将在浏览器网络选项卡的每次调用中获得一个这样的对象。
