SpringBoot-RestTemplate如何實現調用第三方API
1.在build.grdle加入依賴
implementation('org.springframework.boot:spring-boot-starter-web')
2.在config包下創建一個RestTemlateConfig
配置好相關信息
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; @Configuration public class RestTemplateConfig { @Bean public RestTemplate restTemplate(ClientHttpRequestFactory factory){ return new RestTemplate(factory); } @Bean public ClientHttpRequestFactory simpleClientHttpRequestFactory(){ SimpleClientHttpRequestFactory factory = new SimpleClientHttpRequestFactory(); factory.setConnectTimeout(15000); factory.setReadTimeout(5000); return factory; } }
3.在model包下創建一個新的包
“JuHe”,然後包裡創建一個新的類:JuheResult 【Art+insert】選擇CsonFormat
4.Constans類下將調用接口的AppKey值宏定義
package com.qiubao.school.api.common; public interface Constants { String JUHE_KEY = "e80611926aa6321048bde9ea73d11190"; }
5.在controller包下創建一個
新的類SpringRestTemplateController(調用第三方的API,瀏覽器模擬get請求,postman模擬post請求)
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 { @Autowired private RestTemplate restTemplate; /***********HTTP GET method*************/ @GetMapping("/testGetApi") public JuheResult getJson( @RequestParam(value = "type", required = false) String type ){ type = StringUtils.isEmpty(type)?"top":type;//定義為可以為空 // 將調用接口的Key值宏定義一個名字(Constants類下) String url="http://v.juhe.cn/toutiao/index?type="+type+"&key=" + Constants.JUHE_KEY; //將Jason格式轉換為對象(增強可讀性、易於後期數據的更改和增刪) JuheResult result = restTemplate.getForObject(url, JuheResult.class); return result; } //將調用的Api的Jason數據格式修改為需要的Jason數據格式[用到JuheResult方法] private List<Article> convertJuhe2Article(JuheResult result) { List<Article> 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調用接口,驗證是否成功
以上為個人經驗,希望能給大傢一個參考,也希望大傢多多支持WalkonNet。
