url = new URL(UPLOAD_URL);

urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestMethod("PUT");
urlConnection.setRequestProperty("content-type", "application/json");
urlConnection.setFixedLengthStreamingMode(responseJSONArray.toString(2).getBytes("UTF8").length);
urlConnection.setDoInput(false);
urlConnection.setDoOutput(true);
urlConnection.setConnectTimeout(this.CONNECT_TIMEOUT);
urlConnection.connect();
OutputStream output = urlConnection.getOutputStream();
output.write(responseJSONArray.toString(2).getBytes("UTF8"));
output.close();

我之前也已经将 Authenticator 设置为：

Authenticator.setDefault(new Authenticator()
{
 @Override
  protected PasswordAuthentication getPasswordAuthentication()
  {
    return new PasswordAuthentication(loginNameString, passwordString.toCharArray());
  }
});

我提供了正确的登录详细信息，但服务器以401代码响应。（不过，类似的 GET 请求有效。）除此之外，getPasswordAuthentication()在连接和写入流的过程中不会调用该方法。（我知道这一点是因为我输入了Log.v("app", "password here").）

这是为什么？

我无法回答为什么使用 Authenticator 不起作用，但我通常使用这种方法：

    String webPage = "http://192.168.1.1";
    String name = "admin";
    String password = "admin";

    String authString = name + ":" + password;
    byte[] authEncBytes = Base64.encodeBase64(authString.getBytes());
    String authStringEnc = new String(authEncBytes);

    URL url = new URL(webPage);
    URLConnection urlConnection = url.openConnection();
    urlConnection.setRequestProperty("Authorization", "Basic " + authStringEnc);
    InputStream is = urlConnection.getInputStream();
    InputStreamReader isr = new InputStreamReader(is);

试试看。使用基本身份验证就足够了。
