android - 如何在 android 的 JSON 请求中传递 requestUrl 和其他参数中的一半参数？

Question

我是 android 的新手，我做了一个 Activity ，我必须发布一些参数来进行 api 调用并获得响应，我必须传递一些附加到请求 url 的参数和其他 Json 格式的参数，请告诉我我该怎么做，我的示例 url 请求如下:

http://dev.abctest.com/api/v1/book?customer_firstname=jigar&customer_lastname=jims&customer_mobile=9033309333&customer_email=jigar@epagestore.com&source_country=India&number_of_travellers=15

和 json 正文中的其他参数如下:

{

    "destinations": [
        {
            "city_id": 1,
            "start_date": "2014/08/28",
            "end_date": "2014/09/30"
        },
        {
            "city_id": 5,
            "start_date": "2014/08/10",
            "end_date": "2014/09/03"
        }
    ]
}

1. 使用 JsonParserHelper 作为 Utility 类。每次点击 url 时。

a.) 上一个类并在该课上分隔您的网址假设 App_WebServiceUrls

public class App_WebServiceUrls {

public static String GetDetails ="http://dev.abctest.com/api/v1/book";

}

2.现在调用webservice/Web Api时。在单独的线程中调用 api 或使用 Asynctasks所以要避免 NetworkOnMainThredException。

new Thread(new Runnable() {

            @Override
            public void run() {
                // TODO Auto-generated method stub

                // Add your data
            List<NameValuePair> nameValuePair = new ArrayList<NameValuePair>();

                nameValuePair.add(new BasicNameValuePair(customer_firstname, "Deepak"));
                nameValuePair.add(new BasicNameValuePair(customer_lastname, "Panwar"));


JSONObject json = null;

        try {

            json = new JSONObject();

    json = JsonParserHelper.makeHttpRequest(
                    App_WebServiceUrls.CompanyDivisions, "GET", nameValuePair);

            Log.d("Division List Response:", "" + json);

            if (json != null) {
}else
{

    /**To print tost on ui thread**/
    runOnUiThread(new Runnable() {

            @Override
            public void run() {
                // TODO Auto-generated method stub

              /**Write Toast here**/

            }
        });

} catch (JSONException e) {
            e.printStackTrace();
        }


            }
        }).start();

/调用 webapi 的帮助类/

public class JsonParserHelper {

    static InputStream is = null;

    static JSONObject jObj = null;

    static JSONArray jArr = null;

    static String json = "";

    public static JSONObject makeHttpRequest(String url, String method,

    List<NameValuePair> params) {

        try {

            if (method == "POST") {

                DefaultHttpClient httpClient = new DefaultHttpClient();

                String paramString = URLEncodedUtils.format(params, "utf-8");
                url += "?" + paramString;

                Log.v("Urltocheck", "" + url);

                HttpPost httpPost = new HttpPost(url);
                httpPost.setEntity(new UrlEncodedFormEntity(params, "utf-8"));
                HttpResponse httpResponse = httpClient.execute(httpPost);
                HttpEntity httpEntity = httpResponse.getEntity();

                is = httpEntity.getContent();

            } else if (method == "GET") {
                // request method is GET
                DefaultHttpClient httpClient = new DefaultHttpClient();

                String paramString = URLEncodedUtils.format(params, "utf-8");
                url += "?" + paramString;

                Log.v("Urltocheck", "" + url);

                HttpGet httpGet = new HttpGet(url);
                HttpResponse httpResponse = httpClient.execute(httpGet);
                HttpEntity httpEntity = httpResponse.getEntity();
                is = httpEntity.getContent();
            }

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

        try {
            BufferedReader reader = new BufferedReader(new InputStreamReader(
                    is, "iso-8859-1"), 8);
            StringBuilder sb = new StringBuilder();
            String line = null;
            while ((line = reader.readLine()) != null) {
                sb.append(line + "\n");
            }
            is.close();
            json = sb.toString();
        } catch (Exception e) {
            Log.e("Buffer Error", "Error converting result " + e.toString());
        }

        // try parse the string to a JSON object
        try {
            // jArr = new JSONArray(json);

            jObj = new JSONObject(json);
        } catch (JSONException e) {
            Log.e("JSON Parser", "Error parsing data " + e.toString());
        }

        // return JSON String (Array)
        // return jArr;

        return jObj;

    }

}
