网站导航栏下面的文章seol英文啥意思

1.项目准备

        在项目中使用到了jsoup和fastjson jsoup用于创建一个连接(绘画) 用于获取和解析HTML页面

而fastjson对数据进行一个格式化

        在pom.xml导入坐标

    <dependencies><dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>2.0.15.graal</version></dependency><dependency><groupId>org.jsoup</groupId><artifactId>jsoup</artifactId><version>1.15.3</version></dependency></dependencies>

        在爬取数据之前需要先找到对应的数据接口：https://api.inews.qq.com/newsqa/v1/query/inner/publish/modules/list?modules=localCityNCOVDataList,diseaseh5Shelf

        返回的是json数据 这边建议使用json格式化工具观看方便后面提取数据

JSON在线解析,JSON格式化,JSON解析,JSON 校验（SO JSON）

2.实现
