没有弃用HttpClient的Android JSON

Question

我正在寻找一个示例项目，演示如何在不使用现已弃用的HttpClient的情况下将远程JSON对象合并到Android应用程序中。它需要在SDK版本14及更高版本上运行。很难找到任何东西。

非常感谢任何帮助。

谢谢

尝试使用HttpURLConnection。

HttpURLConnection   conn    = null;
 
OutputStream          os   = null;
InputStream           is   = null;
ByteArrayOutputStream baos = null;
 
conn = (HttpURLConnection)url.openConnection();
conn.setConnectTimeout(CONN_TIMEOUT * 1000);
conn.setReadTimeout(READ_TIMEOUT * 1000);
conn.setRequestMethod(POST);
conn.setRequestProperty("Cache-Control", "no-cache");
conn.setRequestProperty("Content-Type", "application/json");
conn.setRequestProperty("Accept", "application/json");
conn.setDoOutput(true);
conn.setDoInput(true);
 
JSONObject job = new JSONObject();
job.put("id", "asdf");
job.put("pw", "asdf");
 
os = conn.getOutputStream();
os.write(job.toString().getBytes());
os.flush();
 
String response;
 
int responseCode = conn.getResponseCode();
 
if(responseCode == HttpURLConnection.HTTP_OK) {
 
    is = conn.getInputStream();
    baos = new ByteArrayOutputStream();
    byte[] byteBuffer = new byte[1024];
    byte[] byteData = null;
    int nLength = 0;
    while((nLength = is.read(byteBuffer, 0, byteBuffer.length)) != -1) {
        baos.write(byteBuffer, 0, nLength);
    }
    byteData = baos.toByteArray();
     
    response = new String(byteData);
     
    JSONObject responseJSON = new JSONObject(response);
    Boolean result = (Boolean) responseJSON.get("result"); 
    String age = (String) responseJSON.get("age");
    String job = (String) responseJSON.get("job");
     
    Log.i(TAG, "DATA response = " + response);
}
