在SwiftUI中对服务器请求使用NavigationButton

import SwiftUI

struct ContentView: View {
    @State private var serverResponse = ""
    
    var body: some View {
        NavigationView {
            VStack {
                Text(serverResponse)
                    .padding()
                
                NavigationLink(destination: DetailView(serverResponse: $serverResponse)) {
                    Text("发送请求")
                        .padding()
                        .background(Color.blue)
                        .foregroundColor(.white)
                        .cornerRadius(10)
                }
            }
            .navigationBarTitle("服务器请求")
        }
    }
}

struct DetailView: View {
    @Binding var serverResponse: String
    
    var body: some View {
        VStack {
            Text(serverResponse)
                .padding()
            
            Button(action: {
                // 发送服务器请求并更新服务器响应
                self.sendRequest()
            }) {
                Text("重新发送请求")
                    .padding()
                    .background(Color.blue)
                    .foregroundColor(.white)
                    .cornerRadius(10)
            }
        }
        .navigationBarTitle("服务器响应")
    }
    
    func sendRequest() {
        guard let url = URL(string: "https://example.com/api/data") else { return }
        
        URLSession.shared.dataTask(with: url) { (data, response, error) in
            if let error = error {
                print("请求错误：\(error.localizedDescription)")
                return
            }
            
            if let data = data {
                let responseString = String(data: data, encoding: .utf8) ?? ""
                DispatchQueue.main.async {
                    self.serverResponse = responseString
                }
            }
        }.resume()
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
