Question

我有一个JSON数据作为字符串，我想将这些数据解码为对象列表，但我得到这个错误：“无法将'String'类型的值转换为预期的参数类型'数据'”

这是我的代码：

struct DatabaseObject: Decodable{
    var CityNameL = ""
    var DBName = ""
    var DBNameID = 0
    var IDName = ""
}

func jsonToObject(json:String){


    do{
     let databases = try  JSONDecoder().decode(DatabaseObject.self,from: json)
    }catch let jsonErr {
     print(jsonErr)
    }
 }

这是json数据：

[{"CityNameL":"Skeleton East","DBName":"SkeletonEAST","DBNameID":29,"IDName":"SKELETONEASTLOCAL"},{"CityNameL":"SKELETON DEMO/SKELETON DEMO","DBName":"SKELETONDEMO","DBNameID":30,"IDName":"SKELETONEASTDOT2"},{"CityNameL":"SKELETONPARAMS","DBName":"FFMSCENTRAL","DBNameID":31,"IDName":"FFMSCENTRALLOCAL"},{"CityNameL":"SKELECBM","DBName":"SKELETONFFMS","DBNameID":32,"IDName":"LOCAL"}]

有没有办法将String转换为数据，或者还有其他解码方法。
