SpringBoot-RestTemplate如何实现调用第三方API
这篇文章主要介绍了SpringBoot-RestTemplate实现调用第三方API的操作，具有很好的参考价值，希望对大家有所帮助。如有错误或未考虑完全的地方，望不吝赐教目录
[*]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;
@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包下创建一个新的包
“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 {
@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<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调用接口，验证是否成功
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CodeAE代码之家。
