想了解SpringBoot-RestTemplate怎样实现调用第三方API的相关内容吗,Lukey Alvin在本文为您仔细讲解SpringBoot RestTemplate调用第三方API的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:SpringBoot,RestTemplate,调用第三方API,下面大家一起来学习吧。

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。
