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; @Service public class UserInfoClient { public String getUserTotalAmount(){ Map<String,String> map=new HashMap<String,String>(); 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; @Service public class UserInfoClient { public String getUserTotalAmount(){ Map<String,String> map=new HashMap<String,String>(); 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<String> entity = new HttpEntity<String>(JSON.toJSONString(map),headers); RestTemplate restTemplate=new RestTemplate(); ResponseEntity<String> 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 @Autowired private RestTemplate restTemplate; @RequestMapping("/FaceInfo") @ResponseBody public 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<String, Object> requestParam = new HashMap<>(); HttpEntity<Map<String, Object>> request = new HttpEntity<Map<String, Object>>(requestParam, headers); ResponseEntity<String> 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 @Autowired private RestTemplate restTemplate; @RequestMapping("/FaceInfo") @ResponseBody public 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<String, Object> requestParam = new HashMap<>(); requestParam.put("loginName", "jnr"); requestParam.put("password", "jn"); HttpEntity<Map<String, Object>> request = new HttpEntity<Map<String, Object>>(requestParam, headers); String s=request.toString(); ResponseEntity<String> entity2 = restTemplate.exchange(apiURL, HttpMethod.POST, request, String.class); String body = entity2.getBody(); return body; }
以上为个人经验,希望能给大家一个参考,也希望大家多多支持脚本之家。
