android - HTTP 使用基本身份验证获取 Android

Question

我是 REST 服务的新手，我正在网上找几个小时......

我有一个 REST 服务 url，可以返回 JSON 数据。 登录名(用户名和密码)是基本身份验证。 我正在寻找一个简单的库/代码 fragment ，它可以让我插入 uri、用户名和密码并返回 JSON 字符串。

如有任何帮助，我们将不胜感激!

也许你可以尝试这样的事情:

StringBuilder builder = new StringBuilder();
HttpClient client = new DefaultHttpClient();
HttpGet httpGet = new HttpGet("YOUR WEBSITE HERE");

// Add authorization header
httpGet.addHeader(BasicScheme.authenticate( new UsernamePasswordCredentials("user", "password"), "UTF-8", false));

// Set up the header types needed to properly transfer JSON
httpGet.setHeader("Content-Type", "application/json");
try {
      HttpResponse response = client.execute(httpGet);
      StatusLine statusLine = response.getStatusLine();
      int statusCode = statusLine.getStatusCode();
      if (statusCode == 200) {
        HttpEntity entity = response.getEntity();
        InputStream content = entity.getContent();
        BufferedReader reader = new BufferedReader(new InputStreamReader(content));
        String line;
        while ((line = reader.readLine()) != null) {
          builder.append(line);
        }
      } else {
        Log.e(ParseJSON.class.toString(), "Failed to download file");
      }
} catch (ClientProtocolException e) {
  e.printStackTrace();
} catch (IOException e) {
  e.printStackTrace();
}

关于编写 JSONObject，请查看以下代码 fragment :

public void writeJSON() {
  JSONObject object = new JSONObject();
  try {
    object.put("name", "Jack Hack");
    object.put("score", new Integer(200));
    object.put("current", new Double(152.32));
    object.put("nickname", "Hacker");
  } catch (JSONException e) {
    e.printStackTrace();
  }
  System.out.println(object);
}
