创建HttpClient对象 CloseableHttpClient httpClient = HttpClientscreateDefault; 创建URIBuilder URIBuilder uriBuilder = new URIBuilderSystem_UrlgetOssDomain+pushpushMessagehtml; 设置字符编码为UTF-8 uri

//创建HttpPost对象 HttpPost httpPost = new HttpPost(uriBuilder.build()); //设置请求参数 List params = new ArrayList<>(); params.add(new BasicNameValuePair("param1", "value1")); params.add(new BasicNameValuePair("param2", "value2")); //将请求参数设置到HttpPost对象中 httpPost.setEntity(new UrlEncodedFormEntity(params, "UTF-8")); //发送请求并获取响应 CloseableHttpResponse response = httpClient.execute(httpPost);
