本文介绍了如何创建一个结构来匹配这个 Json的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我试图从 api 中获取一个随机用户，我创建了一个名为 result 的结构来匹配来自 api 的 json.这是我想出的，但我确定这不是正确的方法！当我运行它时，我得到 [] 结果，所以我想知道如何更改此代码以匹配 json
I am trying to fetch a random user from an api and I created a struct called result to match the json from the api. This is what I came up with but I am sure this is not the right way to do it! When I run this I get [] as a result so I want to know how I can change this code in order to match the json
@State var 结果:结果?
@State var results : result?
struct result : Codable {
var results : [user]
struct user : Codable{
var gender : String
var name : name
var location : location
var email:String
struct name : Codable{
var title : String
var first : String
var last : String
}
struct location : Codable {
let street : street
let city : String
let state : String
let country : String
let postcode : Int
struct street :Codable {
var number : String
var name : String
}
}
struct login : Codable {
var uuid : String
var username : String
var password : String
}
}
}
这是 Json 的样子
This is how the Json looks
