swiftui中服务端图片如何设计view并赋予rotationEffect

这是您要展示的主视图.

struct Stacks: View{
     @State var rotate: [Int] = [-20, 20, 0]
           @State var index: Int = -1
           @StateObject var list = StacksViewModel()
           
           var body: some View{
               VStack(spacing: 35){
                   ForEach(list.datas, id: \.id) { item in
                       ZStack{
                           ForEach(item.stack_book_link.indices, id: \.self) { index in
                               AsyncImage(url: URL(string: item.stack_book_link[index].book_url)){ img in
                                   img.resizable().frame(width: 125, height: 155)
                                       .rotationEffect(Angle(degrees: Double(rotate[ index])))
                                       .shadow(radius: 5)
                               }placeholder: {
                                   Image("u").resizable().frame(width: 125, height: 155).rotationEffect(Angle(degrees: Double(rotate[ index])))
                                       .shadow(radius: 5)
                               }
    
                           }
                       }
                   }
               }
               .onAppear{
                   list.getStacksData()
               }
           } 
    }

这是ViewModel.

class StacksViewModel: ObservableObject{
   
    @Published var datas = [StacksDatum]()
    @Published var image: [String] = []
   
    func getStacksData() {
        
        let defaults = UserDefaults.standard
        guard let token = defaults.string(forKey: "access_token") else {
            return
        }
        //Give authentication(StacksService()) and then fetching data 
        StacksService().getStacksData(token: token){ (result) in
            switch result {
                case .success(let results):
                    DispatchQueue.main.async {
                        self.datas = results.studentStacks.data
                        
                        for data in self.datas {
                            for imgdata in data.stack_book_link{
                                self.image.append(imgdata.book_url)
                            }
                            
                        }
                        print(self.datas)
                    }
                case .failure(let error):
                    print(error.localizedDescription)
            }
        }
    }
      
}

在我这边，它显示得非常正确.我的系统Xcode 14.1和iOS 15.StacksService()是一个类，它提供用户是否通过身份验证的身份验证.
