1.获取数据

    @State var personList = [Person]()
    func load(){
        guard let url = URL(string: "http://192.168.174.243:8080/personlist") else {
            print("无效的地址!")
            return
        }
        let request = URLRequest(url: url)
        URLSession.shared.dataTask(with: request) { data, response, error in
            if let data = data {
                if let response = try? JSONDecoder().decode([Person].self, from: data) {
                    DispatchQueue.main.async {
                        self.personList = response
                    }
                    return
                }
            }
        }.resume()
    }

2.使用数据

    var body: some View {
        
        NavigationView {
            List {
                ForEach (personList) { person in
                    NavigationLink(destination: ContentView(person: person)){
                        VStack(alignment: .leading) {
                            Text(person.name)
                                .font(.title)
                            Text("\(person.age)")
                                .font(.title2)
                        }
                    }
                }
            }.onAppear(perform: load)
            .navigationTitle("demo")
        }
        
    }
