通过HTTP发送JSON服务器放在android的请求 [英] send JSON to server via HTTP put request in android

问题描述

如何包装给JSON字符串，并通过HTTP发送到服务器把请求的Andr​​oid？

How to wrap given json to string and send it to server via Http put request in android?

这是我的JSON的样子。

This is how my json look like.

    {
    "version": "1.0.0",
    "datastreams": [
        {
            "id": "example",
            "current_value": "333"
        },
        {
            "id": "key",
            "current_value": "value"
        },
        {
            "id": "datastream",
            "current_value": "1337"
        }
    ]
}

以上是我的JSON数组。

above is my json array.

我是怎么写的code，但它不工作

below is how I wrote the code but, its not working

        protected String doInBackground(Void... params) {
            String text = null;
            try {
                JSONObject child1 = new JSONObject();
                try{
                    child1.put("id", "LED");
                    child1.put("current_value", "0");


                } catch (JSONException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }


                JSONArray jsonArray = new JSONArray();

                jsonArray.put(child1);

                JSONObject datastreams = new JSONObject();
                datastreams.put("datastreams", jsonArray);  

                JSONObject version = new JSONObject();
                version.put("version", "1.0.0");
                version.put("version", datastreams);


             HttpClient httpClient = new DefaultHttpClient();
             HttpContext localContext = new BasicHttpContext();
             HttpPut put = new HttpPut("url");
             put.addHeader("X-Apikey","");
             StringEntity se = new StringEntity( version.toString());  
             se.setContentType(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));

             put.addHeader("Accept", "application/json");
             put.addHeader("Content-type", "application/json");
             put.setEntity(se);


             try{

                   HttpResponse response = httpClient.execute(put, localContext);
                   HttpEntity entity = response.getEntity();
                   text = getASCIIContentFromEntity(entity);
             }
              catch (Exception e) {
                 return e.getLocalizedMessage();
             }


        }catch (JSONException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (UnsupportedEncodingException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
            return text;
        }

请在这方面的帮助。

推荐答案

如果您preFER使用一个库，然后我会preFER您使用的离子库被Kaush 的。

If you prefer to use a library then I'll prefer you to use Ion Library by Kaush.

构成本库，你可以简单地张贴您的JSON是这样的：

Form this library you can simply post your JSON like this :

JsonObject json = new JsonObject();
json.addProperty("foo", "bar");

Ion.with(context, "http://example.com/post")
.setJsonObjectBody(json)
.asJsonObject()
.setCallback(new FutureCallback<JsonObject>() {
   @Override
    public void onCompleted(Exception e, JsonObject result) {
        // do stuff with the result or error
    }
});
