使用Microsoft进行SwiftUI Firebase身份验证

目前，我正在尝试使用SwiftUI与Microsoft一起使用Firebase身份验证构建应用程序。我的目标是登录Microsoft帐户，获取用户令牌，然后使用令牌调用Microsoft的Graph Api

下面是我获取Microsoft登录页的失败尝试

import Foundation
import Firebase
import AuthenticationServices
import FirebaseAuth


class SignInWithMicrosoftCoordinator {

private var onSignIn: (() -> Void)?
var microsoftProvider : OAuthProvider?
let kGraphURI = "https://graph.microsoft.com/v1.0/me/"
var provider = OAuthProvider(providerID: "microsoft.com")



init() {
    provider.customParameters = [
         "prompt": "consent",
         "login_hint": "user@firstadd.onmicrosoft.com"
       ]
    provider.customParameters = [
         // Optional "tenant" parameter in case you are using an Azure AD
         // tenant. eg. '8eaef023-2b34-4da1-9baa-8bc8c9d6a490' or
         // 'contoso.onmicrosoft.com' or "common" for tenant-independent
         // tokens. The default value is "common".
         "tenant": "TENANT_ID"
       ]
       
    provider.scopes = ["mail.read", "calendars.read", "Directory.ReadWrite.Al"]
}

func logIn() {
    self.microsoftProvider?.getCredentialWith(_: nil) { credential, error in
        if error != nil {
            //handle error
        }
        if let credential = credential {
            Auth.auth().signIn(with: credential) { (authResult, error) in
                if error != nil {
                    
                }
                guard let authResult = authResult else {
                    print("Couln't get graph auth result")
                    return
                }
                
                let microsoftCredential = authResult.credential as! OAuthCredential
                let token = microsoftCredential.accessToken!
                
                //Using token to call Microsoft Graph API
                self.getGraphContentWithToken(accessToken: token)
                
            }
        }
        
    }
}

func getGraphContentWithToken(accessToken: String) {
       
       // Specify the Graph API endpoint
       let url = URL(string: kGraphURI)
       var request = URLRequest(url: url!)
       
       // Set the Authorization header for the request. We use Bearer tokens, so we specify Bearer + the token we got from the result
       request.setValue("Bearer \(accessToken)", forHTTPHeaderField: "Authorization")
       
       URLSession.shared.dataTask(with: request) { data, response, error in
           
           if let error = error {
               print("Couldn't get graph result: \(error)")
               return
           }
           
           guard let result = try? JSONSerialization.jsonObject(with: data!, options: []) else {
               
               print("Couldn't deserialize result JSON")
               return
           }
           
           print("Result from Graph: \(result))")
           
           }.resume()
   }

}

我目前使用的是SwiftUI，没有应用程序代理，我看到其他表单使用这种方法来弹出Microsoft网站。我想知道如何使用按钮的操作打开Microsoft网站Url以登录。谢谢

func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) {
     for urlContext in URLContexts {
        let url = urlContext.url
        Auth.auth().canHandle(url)
      }
 }

func场景（scene:UIScene，openURLContexts:Set）{
对于URLContexts中的urlContext{
让url=urlContext.url
Auth.Auth（）.canHandle（url）
}
}
