只需dayreport字段即可，怎么利用nutz在后端解析？

依然需要全部解析，Json.fromJson

wx_jjn2ia9qvotogktb45bf 2楼•2124天前

无Pojo类对应
Json.fromJson(source/*来源参数*/)
有Pojo类对应
Json.fromJson(Class<T> klass, source/*来源参数*/)
Json.fromJson(Type t, source/*来源参数*/)
Pojo集合或Map嵌套
Json.fromJsonAsArray(Class<T> klass, source/*来源参数*/)
Json.fromJsonAsList(Class<T> klass, source/*来源参数*/)
Json.fromJsonAsMap(Class<T> klass, source/*来源参数*/)
从来源看,一般无难度吧

字符串
Json.fromJson(CharSequence c)
Json.fromJson(Class<T> klass, CharSequence c)
Reader
Json.fromJson(Reader c)
Json.fromJson(Class<T> klass, Reader reader)
File
Json.fromJsonFile(Class<T> klass, File f)

这个是文档上的，解析（这个我可以使用）

但是网址要写在哪？
