Android、HttpURLConnection、PUT 和身份验证器

发布于 2024-11-29 08:34:28 字数 1078 浏览 4 评论 0原文

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();

我之前也已经设置了身份验证器：

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 请求也可以工作。）最重要的是，在连接和写入流的过程中不会调用方法 getPasswordAuthentication()。（我知道这一点是因为我输入了 Log.v("app", "password here")。）

这是为什么？

原文

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();

I've also already earlier set the Authenticator with:

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

I supply correct login details, but the server responds with a 401 code. (A similar GET-request works though.) On top of which, the method getPasswordAuthentication() is not being called in the process of connecting and writing to the stream. (I know this because I put in Log.v("app", "password here").)

Why is that?

我无法回答为什么使用身份验证器不起作用，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);

尝试一下。使用基本身份验证应该足够了。

I'm not able to answer to why using Authenticator does not work, but I usually use this approach:

    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);

Try it. Using basic auth should be enough.
