Android Studio HttpURLConnection 传递 / 发送 JSON 数据

private void request() {
	new Thread(new Runnable() {
	    @Override
	    public void run() {
	    try {
	        String strUrl = "url"; // 你请求的 http 链接
	        URL url = new URL(strUrl);
	        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
	        connection.setRequestMethod("POST"); // 设置请求方式为 GET
            connection.setDoOutput(true);
			connection.setDoInput(true);
			connection.setUseCaches(false);
			connection.connect(); // 连接
			/****************关键***************/
			String body = "{\"字段名\":\"内容\"}";
			BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(connection.getOutputStream(), "UTF-8"));
			writer.write(body);
			writer.close();
			/***********************************/
	        int responseCode = connection.getResponseCode();
	        if (responseCode == HttpURLConnection.HTTP_OK) { // 请求成功
	            InputStream inputStream = connection.getInputStream(); // 得到响应流
	            JSONObject json = streamToJson(inputStream); // 从响应流中提取 JSON
	            Log.i("json", json.toString()); // 打印返回的 JSON 观察处理
	        }
	        connection.disconnect();
	    }
	    catch (Exception e) {
	        e.printStackTrace();
	    }
	    }
	}).start();
}

private JSONObject streamToJson(InputStream inputStream) throws Exception {
    BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream,"UTF-8"));
    String temp = "";
    StringBuilder stringBuilder = new StringBuilder();
    while ((temp = bufferedReader.readLine()) != null) {
        stringBuilder.append(temp);
    }
    JSONObject json = new JSONObject(stringBuilder.toString().trim());
    return json;
}
