SpringBoot-RestTemplate如何实现调用第三方API SpringBoot-RestTemplate如何实现调用

1.在build.grdle加入依赖
2.在config包下创建一个RestTemlateConfig
3.在model包下创建一个新的包
4.Constans类下将调用接口的AppKey值宏定义
5.在controller包下创建一个
6.用Postman调用接口，验证是否成功

1.在build.grdle加入依赖

implementation('org.springframework.boot:spring-boot-starter-web')

2.在config包下创建一个RestTemlateConfig 配置好相关信息

package com.qiubao.school.api.config; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.http.client.ClientHttpRequestFactory; import org.springframework.http.client.SimpleClientHttpRequestFactory; import org.springframework.web.client.RestTemplate; @Configurationpublic class RestTemplateConfig {@Beanpublic RestTemplate restTemplate(ClientHttpRequestFactory factory){return new RestTemplate(factory); } @Beanpublic ClientHttpRequestFactory simpleClientHttpRequestFactory(){SimpleClientHttpRequestFactory factory = new SimpleClientHttpRequestFactory(); factory.setConnectTimeout(15000); factory.setReadTimeout(5000); return factory; }}

3.在model包下创建一个新的包 【SpringBoot-RestTemplate如何实现调用第三方API】“JuHe”，然后包里创建一个新的类：JuheResult 【Art+insert】选择CsonFormat

4.Constans类下将调用接口的AppKey值宏定义

package com.qiubao.school.api.common; public interface Constants {String JUHE_KEY= "e80611926aa6321048bde9ea73d11190"; }

5.在controller包下创建一个新的类SpringRestTemplateController（调用第三方的API，浏览器模拟get请求，postman模拟post请求）

package com.qiubao.school.api.controller; import com.alibaba.fastjson.JSONObject; import com.qiubao.school.api.common.Constants; import com.qiubao.school.api.model.Article; import com.qiubao.school.api.model.juhe.JuheResult; import org.apache.commons.lang3.StringUtils; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.*; import org.springframework.web.client.RestTemplate; import java.util.ArrayList; import java.util.List; @RestController@RequestMapping("news")public class SpringRestTemplateController {@Autowiredprivate RestTemplate restTemplate; /***********HTTP GET method*************/@GetMapping("/testGetApi")public JuheResult getJson(@RequestParam(value = "https://www.it610.com/article/type", required = false) String type){type = StringUtils.isEmpty(type)?"top":type; //定义为可以为空// 将调用接口的Key值宏定义一个名字（Constants类下）String url="http://v.juhe.cn/toutiao/index?type="+type+"&key=" + Constants.JUHE_KEY; //将Jason格式转换为对象（增强可读性、易于后期数据的更改和增删）JuheResult result = restTemplate.getForObject(url, JuheResult.class); return result; }//将调用的Api的Jason数据格式修改为需要的Jason数据格式[用到JuheResult方法]private List convertJuhe2Article(JuheResult result) {List articles = new ArrayList<>(); for (JuheResult.ResultBean.DataBean dataBean:result.getResult().getData()) {Article article = new Article(); article.setUniquekey(dataBean.getUniquekey()); article.setTitle(dataBean.getTitle()); article.setAuthor_name(dataBean.getAuthor_name()); article.setCreateDate(dataBean.getDate()); article.setContent(dataBean.getUrl()); article.setThumbnail_pic_s(dataBean.getThumbnail_pic_s()); article.setThumbnail_pic_s02(dataBean.getThumbnail_pic_s02()); article.setThumbnail_pic_s03(dataBean.getThumbnail_pic_s03()); article.setCategory(dataBean.getCategory()); article.getCommentCount(); article.getLikeCount(); articles.add(article); }return articles; }}

6.用Postman调用接口，验证是否成功
