Question

我目前正在我正在处理的聊天应用程序中实现注册功能。在我的“ SignupViewController”中，我想实现一个名为“ signupButtonPressed”的函数，该函数将我从注册视图控制器路由到“ ListContacts”视图控制器。如果注册失败，则将执行一个名为“ showValidationError”的函数。下面是我的SignupViewController的代码摘录：

================Sending  Sample delay command==============
[28][03][00][A4][00][01][C2][10]
Waiting for a confirmation...
<28><03><02><01><2C><E5><CF>

我正在使用Swift Clean Architecture，因此，我还将代码链接到我的Signup Router，模型和Interactor文件：

1）Signupinteractor.swift：

@IBAction func signupButtonPressed(_ sender: Any) {
    let request = Signup.Request(
    name: fullNameTextField.text!,
    email: emailTextField.text!,
    password: passwordTextField.text!
    )

    interactor?.createAccount(request: request)   
}

func showValidationError(_ message: String) {
    let alertCtrl = UIAlertController(title: "Oops! An error occurred", message: message, preferredStyle: .alert)
    alertCtrl.addAction(UIAlertAction(title: "Ok", style: .cancel, handler: nil))
    self.show(alertCtrl, sender: self)
}

2）SignupModels.swift：

import Foundation

protocol SignupBusinessLogic {
    func createAccount(request: Signup.Request)
}

class SignupInteractor: SignupBusinessLogic {
    var viewController: SignupFormErrorLogic?
    var router: (NSObjectProtocol & SignupRoutingLogic)?
    var worker = UsersWorker()

    func createAccount(request: Signup.Request) -> Void {
        self.worker.signup(request: request) { user, error in

            guard error == nil else {

               print(error!)
                self.viewController?.showValidationError("Error creating account!")
                return
            }

            self.router?.routeToListContacts()
        }
    }
}

3）SignupRouter.swift：

import Foundation

enum Signup {
    struct Request {
        var name: String
        var email: String
        var password: String
    }

    struct Response {
        var user: User?

        init(data: [String:Any]) {
            self.user = User(
                id: data["id"] as! Int,
                name: data["name"] as! String,
                email: data["email"] as! String,
                chatkit_id: data["chatkit_id"] as! String
            )
        }
    }
}

我的UsersWorker.swift文件中的注册功能：

import UIKit

@objc protocol SignupRoutingLogic {
    func routeToListContacts()
}

class SignupRouter: NSObject, SignupRoutingLogic {
    weak var viewController: SignupViewController?

    func routeToListContacts() {
        let storyboard = UIStoryboard(name: "Main", bundle: nil)
        let destinationVC = storyboard.instantiateViewController(withIdentifier: "MainNavigator") as! UINavigationController

        viewController!.show(destinationVC, sender: nil)
    }
}

当我在注册UITextfields（fullNameTextField； emailTextField； passwordTextField）中输入注册详细信息并按下注册按钮时，会触发一个名为“ CannotSignup”的错误。但是不确定为什么。这种情况也可以在我的UsersWorker.swift文件中找到：

func signup(request: Signup.Request, completionHandler: @escaping (User?, UsersStoreError?) -> Void) {
    let params: Parameters = [
        "name": request.name,
        "email": request.email,
        "password": request.password
    ]

    postRequest("/api/users/signup", params: params, headers: nil) { data in
        guard data != nil else {
            return completionHandler(nil, UsersStoreError.CannotSignup)
        }

        let response = Signup.Response(data: data!)
        CurrentUserIDDataStore().setID(CurrentUserID(id: response.user?.chatkit_id))

        let request = Login.Account.Request(
            email: request.email,
            password: request.password
        )

        self.login(request: request) { token, error in
            guard error == nil else {
                return completionHandler(nil, UsersStoreError.CannotLogin)
            }

            DispatchQueue.main.async {
                completionHandler(response.user, nil)
            }
        }
    }
}

如果有人能够查看代码以了解问题的根源以及如何解决这个问题，那将是很好的选择？如果需要进一步的信息，请询问！

很可能是API调用失败，请检查返回的HTTP状态代码而不是window.addEventListener('hashchange', (event: HashChangeEvent) => { const { target: { location: { hash } } } = event; /* ... */ });。在某些情况下，没有任何响应数据，API调用即可成功理想情况下，还要发送一个TS2339: Property 'location' does not exist on type 'EventTarget | null'.实例以及从data方法返回的数据
