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=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 = "/spring")public class Test { @RequestMapping(value = "/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 = "/spring")public class Test { @RequestMapping(value = "/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 Object faceInfo(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;}使用Post方式，携带body请求数据//注入@Autowiredprivate RestTemplate restTemplate;@RequestMapping("/FaceInfo")@ResponseBodypublic Object faceInfo(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;}以上就是关于"Springboot HTTP怎么调用其他服务"这篇文章的内容，相信大家都有了一定的了解，希望小编分享的内容对大家有帮助，若想了解更多相关的知识内容，请关注行业资讯频道。
