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-.URI;

import java.util.HashMap;

import java.util.Map;

@Service

public 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

*/

returQCpdzNirn "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 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.setConterQCpdzNintType(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

@Autowired

private RestTemplate restTemplate;

@RequestMapping("/FaceInfo")

@ResponseBody

public Object faceInfo(String startTime,String endTime,Integer size ){

String apiURL = "http://05un-/wspp/GceGroups";

HttpHeaders headers = new HttpHeaders();

headers.add("userId","38");

// headers.set("userId","38");

headers.setContentType(MediaType.APPLICATION_JSON);

Map requestParam = new HashMap<>();

HttpEntity

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

@Autowired

private RestTemplate restTemplate;

@RequestMapping("/FaceInfo")

@ResponseBody

public Object faceInfo(String startTimerQCpdzNi,String endTime,Integer size ){

String apiURL = "http://0531yun-/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

String s=request.toString();

ResponseEntity entity2 = restTemplate.exchange(apiURL, HttpMethod.POST, request, String.class);

String body = entity2.getBody();

return body;

}
