manu请求javascript的一个自动化

我是用java做的：

CredentialsProvider credentialsProvider = new BasicCredentialsProvider();
            credentialsProvider.setCredentials(
                    new AuthScope(url, Integer.valueOf(porta)),
                    new UsernamePasswordCredentials(usuario, senha));
            HttpClient client = HttpClientBuilder.create()
                    .setDefaultCredentialsProvider(credentialsProvider)
                    .build();

            String[] canalArr = canais.split(" ");
            HttpGet get;
            String urlCftv;
            for (String canal : canalArr) {}

我不能在javascript中执行许多请求，我只需要执行一次身份验证，然后执行manu请求
