【RestTemplate】post请求示例

引包：

import org.springframework.util.LinkedMultiValueMap;
import org.springframework.util.MultiValueMap;
import org.springframework.web.client.RestTemplate;

代码：

        RestTemplate restTemplate = new RestTemplate();
        MultiValueMap<String,Object> paramMap=new LinkedMultiValueMap<String,Object>();
        paramMap.add("name", "何杨");
        paramMap.add("pswd", "1");
        String rsps=restTemplate.postForObject("http://localhost:8080/mediacool/probeUser", paramMap, String.class);
        System.out.println(rsps);

响应：

{"Interface ID":"8973","startTime":"2021-10-31 11:51:30.261381200","visitorIp":"192.168.0.101","code":"303","msg":"确认用户名和密码无误","userInfo":{"id":1,"name":"何杨","email":"1@2.3"},"endTime":"2021-10-31 11:51:30.651390"}
