HttpClient——POST请求方法

CloseableHttpClient httpClient = HttpClients.createDefault();  

//如果发送是POST请求，创建HttpPost对象
HttpPost httppost = new HttpPost("http://localhost:8080/login");  

//post请求参数配置
List<NameValuePair> formparams = new ArrayList<NameValuePair>(); 
formparams.add(new BasicNameValuePair("name", "xxx"));
formparams.add(new BasicNameValuePair("pwd", "123456")); 
UrlEncodedFormEntity uefEntity = new UrlEncodedFormEntity(formparams, "UTF-8");   //设置编码格式为utf-8
httppost.setEntity(uefEntity);  //设置POST请求参数

//使用httpclient的execute方法发送接口请求
CloseableHttpResponse response =  httpClient.execute(httppost);
