Chrome DevTools 网络功能

使用 CDP 的网络功能。

尽管 Selenium 4 提供了对 Chrome DevTools 协议的直接访问，但当 WebDriver BiDi 实现后，这些方法最终将被删除。

基本身份验证

某些应用程序使用浏览器身份验证来保护页面。以前通常在 URL 中处理它们，但浏览器已停止支持此功能。通过此代码，您可以在必要时将凭据插入到标头中。

    Predicate<URI> uriPredicate = uri -> uri.toString().contains("herokuapp.com");
    Supplier<Credentials> authentication = UsernameAndPassword.of("admin", "admin");
    ((HasAuthentication) driver).register(uriPredicate, authentication);

        credentials = base64.b64encode("admin:admin".encode()).decode()
        auth = {'authorization': 'Basic ' + credentials}
        await connection.session.execute(connection.devtools.network.set_extra_http_headers(Headers(auth)))

                Credentials = new PasswordCredentials("admin", "admin")
            };
            var networkInterceptor = driver.Manage().Network;

网络拦截

可以记录或转换请求和响应。

响应信息

    try (NetworkInterceptor ignored =
        new NetworkInterceptor(
            driver,
            (Filter)
                next ->
                    req -> {
                      HttpResponse res = next.execute(req);
                      contentType.add(res.getHeader("Content-Type"));
