HTTP如何调用其他服务

1.GET请求
2.POST请求

springboot请求其他服务器的http接口

使用Get方式，携带headers请求数据
使用Post方式，携带body请求数据

HTTP如何调用其他服务
1.GET请求
1.1Client代码

import com.alibaba.fastjson.JSON; import org.springframework.stereotype.Service; import org.springframework.web.client.RestTemplate; import org.springframework.web.util.UriComponentsBuilder; import java.net.URI; import java.util.HashMap; import java.util.Map; @Servicepublic class UserInfoClient {public String getUserTotalAmount(){Map map=new HashMap(); map.put("name","123"); map.put("password","123"); URI uri = UriComponentsBuilder.fromHttpUrl("http://localhost:8081/spring/test").queryParam("jsonString",JSON.toJSONString(map)).queryParam("token","12122222111").build().encode().toUri(); RestTemplate restTemplate=new RestTemplate(); String data=https://www.it610.com/article/restTemplate.getForObject(uri,String.class); System.out.println(data); return null; }public static void main(String[] args){UserInfoClient c=new UserInfoClient(); c.getUserTotalAmount(); }}

1.2 Service 代码

import org.springframework.web.bind.annotation.*; @RestController@RequestMapping(value = "https://www.it610.com/spring")public class Test {@RequestMapping(value = "https://www.it610.com/test",method = RequestMethod.GET)public String testSpringBoot(@RequestParam String jsonString,@RequestParam String token){System.out.println(jsonString); System.out.println(token); /**逻辑处理*/return "Spring Boot 测试成功！"; }}

2.POST请求
2.1Client代码

import com.alibaba.fastjson.JSON; import org.springframework.http.*; import org.springframework.stereotype.Service; import org.springframework.web.client.RestTemplate; import java.util.HashMap; import java.util.Map; @Servicepublic class UserInfoClient { public String getUserTotalAmount(){Map map=new HashMap(); map.put("name","123"); map.put("password","123"); String url="http://localhost:8081/spring/test"; //设置请求头信息HttpHeaders headers = new HttpHeaders(); MediaType type = MediaType.parseMediaType("application/json; charset=UTF-8"); headers.setContentType(type); headers.add("Accept", MediaType.APPLICATION_JSON.toString()); //设置body部分HttpEntity entity = new HttpEntity(JSON.toJSONString(map),headers); RestTemplate restTemplate=new RestTemplate(); ResponseEntity result = restTemplate.exchange(url, HttpMethod.POST, entity, String.class); System.out.println(result.getBody()); return null; }public static void main(String[] args){UserInfoClient c=new UserInfoClient(); c.getUserTotalAmount(); }}

2.2 Service代码

import org.springframework.web.bind.annotation.*; @RestController@RequestMapping(value = "https://www.it610.com/spring")public class Test {@RequestMapping(value = "https://www.it610.com/test",method = RequestMethod.POST)public String testSpringBoot(@RequestBody UserBean userBean){System.out.println(userBean); /**逻辑处理*/return "Spring Boot 测试成功！"; }}

springboot请求其他服务器的http接口
使用Get方式，携带headers请求数据

//注入@Autowiredprivate RestTemplate restTemplate; @RequestMapping("/FaceInfo")@ResponseBodypublic ObjectfaceInfo(String startTime,String endTime,Integer size ){String apiURL = "http://www.05un.cn/wspp/GceGroups"; HttpHeaders headers = new HttpHeaders(); headers.add("userId","38"); // headers.set("userId","38"); headers.setContentType(MediaType.APPLICATION_JSON); Map requestParam = new HashMap<>(); HttpEntity request = new HttpEntity(requestParam, headers); ResponseEntity entity2 = restTemplate.exchange(apiURL, HttpMethod.GET, request, String.class); String body = entity2.getBody(); return body; }

【Springboot|Springboot HTTP如何调用其他服务】
使用Post方式，携带body请求数据

//注入@Autowiredprivate RestTemplate restTemplate; @RequestMapping("/FaceInfo")@ResponseBodypublic ObjectfaceInfo(String startTime,String endTime,Integer size ){String apiURL = "http://www.0531yun.cn/wsjc/app/Login"; HttpHeaders headers = new HttpHeaders(); headers.setContentType(MediaType.APPLICATION_JSON); Map requestParam = new HashMap<>(); requestParam.put("loginName", "jnr"); requestParam.put("password", "jn"); HttpEntity request = new HttpEntity(requestParam, headers); String s=request.toString(); ResponseEntity entity2 = restTemplate.exchange(apiURL, HttpMethod.POST, request, String.class); String body = entity2.getBody(); return body; }
