Swiftui ImagePicker触发api发布照片

如何解决Swiftui ImagePicker触发api发布照片

我正在尝试编写用于在swiftui中发布个人资料照片的代码。我找到了从图库中选择照片的示例。现在，我尝试添加HTTP请求以将图像发布到API。但是我不知道我应该在哪里找到我的API帖子。 用户从imagePicker中选择照片后，它将能够触发api发布。有人对此有想法吗？谢谢。

import SwiftUI

struct ContentView: View {
    
    @State var isShowPicker: Bool = false
    @State var image: Image? = Image("profile")
    
    var body: some View {
        NavigationView {
            ZStack {
                vstack {
                    image?
                        .resizable()
                        .clipShape(Circle())
                        .frame(width: 150,height: 150)
                        .scaledToFit()
                        .onTapGesture {
                            self.isShowPicker.toggle()
                    }
                    Spacer()
                }
            }
            .sheet(isPresented: $isShowPicker) {
                ImagePicker(image: self.$image)
            }
            .navigationBarTitle("Pick Image")
        }
    }
}

图像选择器

struct ImagePicker: UIViewControllerRepresentable {
    
    @Environment(\.presentationMode)
    var presentationMode
    
    @Binding var image: Image?
    
    class Coordinator: NSObject,UINavigationControllerDelegate,UIImagePickerControllerDelegate {
        
        @Binding var presentationMode: PresentationMode
        @Binding var image: Image?
        
        init(presentationMode: Binding<PresentationMode>,image: Binding<Image?>) {
            _presentationMode = presentationMode
            _image = image
        }
        
        func imagePickerController(_ picker: UIImagePickerController,didFinishPickingMediawithInfo info: [UIImagePickerController.InfoKey : Any]) {
            let uiImage = info[UIImagePickerController.InfoKey.originalImage] as! UIImage
            image = Image(uiImage: uiImage)
            print(image! as Any)
            presentationMode.dismiss()
            
        }
        
        func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
            presentationMode.dismiss()
        }
        
    }
    
    func makeCoordinator() -> Coordinator {
        return Coordinator(presentationMode: presentationMode,image: $image)
    }
    
    func makeUIViewController(context: UIViewControllerRepresentableContext<ImagePicker>) -> UIImagePickerController {
        let picker = UIImagePickerController()
        picker.delegate = context.coordinator
        return picker
    }
    
    func updateUIViewController(_ uiViewController: UIImagePickerController,context: UIViewControllerRepresentableContext<ImagePicker>) {
        
    }
    
}

解决方法

在此处及下方使用Image代替使用UIImage（如在此处和此处传递），则可以将其转换为数据并发布

struct ContentView: View {
    
    @State var isShowPicker: Bool = false

    // now you store UIImage,so can use/pass in action `.jpegData(...`
    @State var image: UIImage? = UIImage(named: "profile")
    
    var body: some View {
        NavigationView {
            ZStack {
                VStack {
                    Image(uiImage: self.image ?? UIImage())
