Android：如何使用json / php webservice将数据发布到mysql服务器

Question

你好，我是这个领域的初学者。我知道如何从数据库中获取数据，但我不知道如何在webserve上将数据发布到数据库。

我无法弄清楚将数据发布到网络服务器的问题。

• 你们能不能给我一个注册页/报告错误等页面的代码。通过检查代码，我将能够理解逻辑。
• 如何处理post和json解析的理论。

这是我用于解析的类：

public class ServiceHandler{

    static String response = null;
    public final static int GET = 1;
    public final static int POST = 2;

    public ServiceHandler() {

    }
    public String makeServiceCall(String url, int method) {
        return this.makeServiceCall(url, method, null);
    }

    public String makeServiceCall(String url, int method,
            List<NameValuePair> params) {
        try {
            // http client
            DefaultHttpClient httpClient = new DefaultHttpClient();
            HttpEntity httpEntity = null;
            HttpResponse httpResponse = null;

            // Checking http request method type
            if (method == POST) {
                HttpPost httpPost = new HttpPost(url);
                // adding post params
                if (params != null) {
                    httpPost.setEntity(new UrlEncodedFormEntity(params));
                }

                httpResponse = httpClient.execute(httpPost);

            } else if (method == GET) {
                // appending params to url
                if (params != null) {
                    String paramString = URLEncodedUtils
                            .format(params, "utf-8");
                    url += "?" + paramString;
                }
                HttpGet httpGet = new HttpGet(url);

                httpResponse = httpClient.execute(httpGet);

            }
            httpEntity = httpResponse.getEntity();
            response = EntityUtils.toString(httpEntity);

        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }


        return response;

    }
}
