Answer 1

試試這個代碼

Button show_data;
JSONObject my_json_obj;
String path,firstname,lastname;
path = "http://192.168.101.123:255/services/services.php?id=9";
    HttpClient client = new DefaultHttpClient();
    HttpConnectionParams.setConnectionTimeout(client.getParams(), 10000);
    HttpEntity  entity;
    HttpResponse response = null;
    HttpURLConnection urlconn;
    my_json_obj = new JSONObject();
    try
    {
        urlconn = (HttpURLConnection) new URL(path).openConnection();
        urlconn.setConnectTimeout(10000);
        urlconn.setDoOutput(true);

        OutputStreamWriter writer = new OutputStreamWriter(urlconn.getOutputStream(), "UTF-8");

my_json_obj.put("sUserName", "test2");
      my_json_obj.put("sPassword", "123456");

writer.write(my_json_obj.toString());
        writer.close();

if(true)
        {
            String temp;
            temp = WebRequestCall(my_json_obj);
            //Log.i("Reply", temp);
        }

我想這更像是另一種方式：您通過 HTTP 發送 JSON 數據。

看看HttpURLConnection和org.json.*類。

你看過 Volley 和/或 Retrofit 嗎？ 如果登錄不僅僅是您需要進行的操作，它們會很有幫助。
