Android HttpUrlConnection 不支持摘要认证？

Question

• 我想使用HTTPURLConnection来启用基于doc的android支持的缓存

• 但是当使用 HTTPURLConnection 时返回 401 responseCode 。

      String BASIC_AUTH = "Basic "
          + Base64.encodeToString((USER+":"+PASS).getBytes(),
                  Base64.NO_WRAP);
  HttpURLConnection con = (HttpURLConnection) urlObj.openConnection();
  
  con.setConnectTimeout(CONNECT_TIMEOUT);
  con.setReadTimeout(READ_TIMEOUT);
  con.setRequestProperty("Authorization", BASIC_AUTH);
  // Enable cache
  con.setUseCaches(true);
  con.setRequestProperty("Content-Type", "application/json");
  con.setRequestProperty("Accept", "*/*");
  // add reuqest header
  con.setRequestMethod("GET");
  int responseCode = con.getResponseCode();
  Log.d("Response Code : ", responseCode + ""); // return 401
  

• 使用 apache 时 DefaultHttpClient 完美运行。

      DefaultHttpClient httpClient = new DefaultHttpClient();
  httpClient.getCredentialsProvider().setCredentials(
          new AuthScope(null, -1),
          new UsernamePasswordCredentials(USER,PASS));
  
  HttpResponse httpResponse;
  HttpEntity httpEntity;
  String url = apiURL.getURL();
  // request method is GET
  String paramString = URLEncodedUtils.format(params, "utf-8");
  url += "?" + paramString;
  HttpGet httpGet = new HttpGet(url);
  httpGet.setHeader("Accept", "text/json");
  httpResponse = httpClient.execute(httpGet);
  httpEntity = httpResponse.getEntity();
  

• 如何在HTTPURLConnecion 上设置Credentials 以像apache DefaultHttpClient 一样工作的问题。

Answer 1

设置凭据的默认机制是使用Authenticator.setDefault，但它仅适用于基本身份验证。

Android 上的HttpUrlConnection 尚不支持摘要，因此您必须自己实现RFC2617。

试试不带空格的"user:pass"。
