SpringBoot-RestTemplate如何实现调用第三方API

小蚂蚁

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

• 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。
