Code to POST JSON in Java

Since it is not necessary to save the data that I want to have temporarily in the DB, I made it possible to post and share it as a JSON String.

`postJSON`


	public String postJson(String json, String path) {
		HttpURLConnection uc;
		try {
			URL url = new URL("http://host"+path);
			uc = (HttpURLConnection) url.openConnection();
			uc.setRequestMethod("POST");
			uc.setUseCaches(false);
			uc.setDoOutput(true);
			uc.setRequestProperty("Content-Type", "application/json; charset=utf-8");
			OutputStreamWriter out = new OutputStreamWriter(
				new BufferedOutputStream(uc.getOutputStream()));
			out.write(json);
			out.close();

			BufferedReader in = new BufferedReader(new InputStreamReader(uc.getInputStream()));
			String line = in.readLine();
			String body = "";
			while (line != null) {
				body = body + line;
				line = in.readLine();
			}
			uc.disconnect();
			return body;
		} catch (IOException e) {
			e.printStackTrace();
			return "client - IOException : " + e.getMessage();
		}
	}

Servlet side code

Receives POSTed data and stores it as JSONArray and JSONObject.

`doPost`


	protected void doPost(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
		request.setCharacterEncoding("UTF-8");
		response.setContentType("application/json; charset=utf-8");
		BufferedReader br = new BufferedReader(request.getReader());
		String line = br.readLine();
		String body = "";
		if (line != null) {
			body = body + line;
			line = br.readLine();
		}
		PrintWriter out = response.getWriter();
		out.println("{\"status\":\"OK\"}");
		out.flush();
		out.close();

		try {
			LinkedList todo = new LinkedList();
			JSONArray ja = new JSONArray(body);
			for (int i = 0; i < ja.length(); i++) {
				JSONObject tdj = (JSONObject) ja.get(i);
				//Processing addition
			}
		} catch (JSONException e) {
			e.printStackTrace();
		}
	}
