问题描述
在构建社交媒体应用程序时遇到问题。
我已经在我的LoginView上集成了一个“ Google登录按钮”（使用客户端ID，没有Firebase，GoogleSignIn Framework），并且在我登录gmail帐户后，它使我回到了相同的LoginView。
我想导航到SignUpView 
我正在从 AppDelegate
中的功能获取用户数据func sign(_ signIn: GIDSignIn!,didSignInFor user: GIDGoogleUser!,withError error: Error!) {
if let error = error {
if (error as NSError).code == GIDSignInErrorCode.hasNoAuthInKeychain.rawValue {
print("The user has not signed in before or they have since signed out.")
} else {
print("\(error.localizedDescription)")
}
return
}
getGoogleUserData(with: user)
现在，使用用户的idToken，我将数据发布到Graphql中的backendServer上，无论用户是否注册，我都将获取信息。
fileprivate func getAuth(with idToken : String) {
let params = ["id_token":"\((idToken))"]
print(params)
var request = URLRequest(url: URL(string: "confidential_URL_here")!)
request.httpMethod = "POST"
request.httpBody = try? JSONSerialization.data(withJSONObject: params,options: [])
request.addValue("application/json",forHTTPHeaderField: "Content-Type")
let session = URLSession.shared
let task = session.dataTask(with: request,completionHandler: { data,response,error -> Void in
if let safeData = data {
ParsingUserjson().parseJSON(with: safeData)
}
})
task.resume()
}
这是我的parseJSON函数。我需要在此功能后执行此操作方面的帮助：-
class ParsingUserjson: ObservableObject {
func parseJSON(with loginjsON : Data) {
let decoder = JSONDecoder()
do{
let decodedUser = try decoder.decode(LoginData.self,from: loginjsON)
guard let shouldSignUp = decodedUser.user?.signin //This tells me whether the user is entering the app for first time or not
else {
fatalError("Could not achieve signIn boolean data from loginjsON")
}
guard let accesstoken = decodedUser.accesstoken
else {
fatalError("Could not get accesstoken from the loginjsON")
}
//I am checking if the user has created not created his username and is entering for first time
if decodedUser.user?.username == nil || shouldSignUp == true
{
//**THIS IS THE PART I AM NEED HELP. WHAT TO DO AFTER THIS? HOW TO GO FROM HERE>**
}
else {
guard let userName = decodedUser.user?.username else { return }
}
}catch{
fatalError("Could not decode loginjsON")
}
}
}
现在，有人可以帮助我如何将数据发送回LoginView并使用NavigationLink导航到SignUpView吗？还是有其他方法可以做到这一点。
