java - 如何通过 Java BufferedReader 从 Nexmo.com get-balance API 获取正确的 XML 页面？

Question

我尝试调用 Nexmo.com 的 get-balance web/RESTful API 来获取帐户余额，但收到两种错误响应:(1)400 - 在 GAE-Java runtme 中找不到页面。 (2)Java SE 运行时中的FileNotFoundException。如何通过Java BufferedReader获取正确的XML页面？

String api =  "http://rest.nexmo.com/account/get-balance/{idkey}/{pwkey}";
URL url = new URL(api);
BufferedReader reader = new BufferedReader(new InputStreamReader(url.openStream()));
while ((line = reader.readLine()) != null) {
...

    String strURL = "http://rest.nexmo.com/account/get-balance/";
    strURL += USERNAME + "/" + PASSWORD;
    GetMethod get = new GetMethod(strURL);
    get.addRequestHeader("Accept", "application/xml");
    HttpClient httpclient = new HttpClient();
    try {
        int result = httpclient.executeMethod(get);
        System.out.println("Response status code: " + result);
        String responseBodyAsString = get.getResponseBodyAsString();
        System.out.println("responseBodyAsString: " + responseBodyAsString);
    } finally {
        get.releaseConnection();
    }
