Java HttpClient POST请求示例：传递参数并获取响应

//创建HttpClient对象\nCloseableHttpClient httpClient = HttpClients.createDefault();\n//创建URIBuilder\nURIBuilder uriBuilder = new URIBuilder(System_Url.getOssDomain()+"/push/pushMessage.html");\n//设置字符编码为UTF-8\nuriBuilder.setCharset(StandardCharsets.UTF_8);\n使用post请求传递参数内容：//创建HttpPost对象\nHttpPost httpPost = new HttpPost(uriBuilder.build());\n//设置请求参数\nList params = new ArrayList<>();\nparams.add(new BasicNameValuePair("param1", "value1"));\nparams.add(new BasicNameValuePair("param2", "value2"));\n//将请求参数设置到HttpPost对象中\nhttpPost.setEntity(new UrlEncodedFormEntity(params, "UTF-8"));\n//发送请求并获取响应\nCloseableHttpResponse response = httpClient.execute(httpPost);
