而fastjson对数据进行一个格式化 在pom.xml导入坐标 dependenciesdependencygroupIdcom.alibaba/groupIdartifactIdfastjson/artifactIdversion2.0.15.graal/version/dependencydependencygroupIdorg.jsoup/groupIdartifactIdjsoup/artifactIdversion1.15.3/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?moduleslocalCityNCOVDataList,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
