使用Java获取MailChimp响应

Question

我想使用MailChimp api添加订阅者。首先，想从一个REST中读取信息，我正试图从MailChimp api中获得响应。

当我的状态为200时，我似乎正在正确地进行授权，但是由于某种原因，我没有得到响应。

这是到目前为止的代码：

public void doPostAction() throws IOException{

    // BASIC Authentication
    String name = "user";
    String password = apikey;
    String authString = name + ":" + password;

    byte[] authEncBytes = Base64.encodeBase64(authString.getBytes());
    String authStringEnc = new String(authEncBytes);

    URL urlConnector = new URL(url);
    HttpURLConnection httpConnection = (HttpURLConnection) urlConnector.openConnection();
    httpConnection.setRequestMethod("GET");
    httpConnection.setDoOutput(true);
    httpConnection.setDoInput(true);
    httpConnection.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
    httpConnection.setRequestProperty("Accept", "application/json");
    httpConnection.setRequestProperty("Authorization", "Basic " + authStringEnc);

    InputStream is = httpConnection.getInputStream();

    // check status
    System.out.println("DoPost: status: " + httpConnection.getResponseCode());

    StringBuilder sb = new StringBuilder();
    BufferedReader br = new BufferedReader(new InputStreamReader(is, "utf-8"));

    String line = null;
    while ((line = br.readLine()) != null) {
        sb.append(line + "\n");
                }
    System.out.println("DoPost response: \n" + line);
    br.close(); 
}

看着MailChimp游乐场，似乎我很想念...

我如何获得回复？

**** /编辑/ **** 如果有人在看上面的代码，输出应该是：

System.out.println("DoPost response: \n" + sb);  // not line

Answer 1

确定，以上代码有效。基本错误。

我正在检查line变量为null时的值，而不是响应...

当我更改为：

System.out.println("DoPost response: \n" + line);  // not line
System.out.println("DoPost response: \n" + sb);  // but sb StringBuilder

...有效。
