试图找出通过Android将数据发送到服务器的最佳方法

Question

I'm trying to figure out what the best method to send two strings and an integer to a server. Should I use a database? I want to achieve a queue effect and not really store the data online for too long. I just want to grab the information in the queue with a different program. The android would just need to send the data to the web server, but I'm not sure what kind of data structures I should be researching.

So I'm really looking for ideas of some kind of scripts I can be running on a web-server and how to implement sending to them via android. I don't need specific code, but an idea I could research would work too. I really appreciate any help.

Simple, Encode what you need to send in JSON and send it. I'll quote an example below, I have a server running Django and have set up an API to save the data into the database when I hit the url with a post request. I send the Location (latitude and longitude) along with the current datetime. On my server a view runs and parses the json and then saves it to DB.

In your case however you can just manipulate the data the way you want and not save it.

    try 
    {
            double la = 30.1955600 ;
            double lo = 71.4752800;
            Time t = new Time(Time.getCurrentTimezone());
            t.setToNow();
            String date = t.format("%Y-%m-%d %H:%M:%S");


            JSONObject o1 = null;                                                               
            o1 = new JSONObject();
            o1.put("latitude", loc.latitude);
            o1.put("longitude", loc.longitude);
            o1.put("date_added", date);




            // http call//
            HttpClient httpClient = new DefaultHttpClient();

            HttpPost request = new HttpPost("the url you want to hit");

            StringEntity _params =new StringEntity(o1.toString());

            request.addHeader("content-type", "application/json");

            request.setEntity(_params);
            HttpResponse response = httpClient.execute(request);    
    //check to see if we got a response

            if (response.getEntity() != null)
                HomeScreen.location_sent = true;
            else
                HomeScreen.location_sent = false;

    }
    catch (Exception e) 
    {
        e.getMessage();
    }
