本文提供了一个使用Java实现HTTP POST请求的示例代码。通过CloseableHttpClient发起POST请求，并设置请求头及请求体，最终解析响应结果为JSON对象。

    public static JSONObject doPost(String url,String outUrl){
        JSONObject jsonObject=null;
        CloseableHttpClient httpClient = HttpClients.createDefault();
        HttpPost httpPost = new HttpPost();
        httpPost.setEntity(new StringEntity(outUrl,"UTF-8"));
        URI uri = null;
        try {
            uri = new URI(url);//视频中忘了加url，所以输出httpPost，会显示POST null HTTP/1.1
        } 
        catch (URISyntaxException e1) {
            e1.printStackTrace();
        }
        httpPost.setURI(uri);
        System.out.println(httpPost);//POST null HTTP/1.1
        try {
            HttpResponse reponse = httpClient.execute(httpPost);
            String result = EntityUtils.toString(reponse.getEntity(),"UTF-8");
            System.out.println(result);
            jsonObject=JSONObject.fromObject(result);
            System.out.println(jsonObject);
        } 
        catch (ClientProtocolException e) {
            e.printStackTrace();
        } 
        catch (IOException e) {
            e.printStackTrace();
        }

        return jsonObject;
    }
