无法正常工作-在Swift 3/4中以编程方式在Api中注册用户 [英] Not working - Registering User in Api Programatically in Swift 3/4

问题描述

我正在尝试在我的API中注册用户。当我在Postman中进行操作时，它会注册用户并返回状态为true，并以用户创建的身份返回消息，但是当我尝试以编程方式快速创建新用户时，它始终显示用户已经存在（给出错误的响应），即使它没有注册。我正在使用Swift 4 Xcode 9。

I'm trying to register a user in my API. When I do it in Postman, it registers the user and returns the status as true and message as User Created, but when I try to create a new user from swift programatically it always shows User already exists (giving false response), even though it is not registered. I'm Using Swift 4 Xcode 9.

几乎相同的代码适用于Sign In Api，但不适用于用户注册。而且，在我通过Api中的邮递员注册该用户后，它对于Login来说可以正常工作。所以我没有发现RegisterUser的问题所在。代码没有显示错误。

The almost same code work works for Sign In Api, but not working for User Registration. Also, after I register that user through postman in Api, it works perfectly fine for Login. So I'm not getting what the problem is with RegisterUser. Code shows no error.

这是我用于注册用户的代码：

Here is my code for registeringUser:

import UIKit
import SwiftyJSON
import Alamofire
import SwiftKeychainWrapper

class RegisterUserViewController: UIViewController {
    @IBOutlet weak var firstNameTextField: UITextField!
    @IBOutlet weak var lastNameTextField: UITextField!
    @IBOutlet weak var emailAddressTextField: UITextField!
    @IBOutlet weak var passwordTextField: UITextField!
    @IBOutlet weak var repeatPasswordTextField: UITextField!

    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    @IBAction func cancelButtonTapped(_ sender: Any) {
        print("Cancel button tapped")

        self.dismiss(animated: true, completion: nil)
    }


    @IBAction func signupButtonTapped(_ sender: Any) {
       print("Sign up button tapped")


        // Validate required fields are not empty
        if (firstNameTextField.text?.isEmpty)! ||
            (lastNameTextField.text?.isEmpty)! ||
            (emailAddressTextField.text?.isEmpty)! ||
            (passwordTextField.text?.isEmpty)!
        {
            // Display Alert message and return
            displayMessage(userMessage: "All fields are quired to fill in")
            return
        }

        // Validate password
        if ((passwordTextField.text?.elementsEqual(repeatPasswordTextField.text!))! != true)
        {
            // Display alert message and return
            displayMessage(userMessage: "Please make sure that passwords match")
            return
        }



        let userdefault = UserDefaults.standard
        userdefault.set(emailAddressTextField.text, forKey: "email_id")
        //userdefault.set(emailAddressTextField, forKey: "email_id")
         print("email_id",emailAddressTextField.text)

        //print("email_address",userdefault.string(forKey: "email_id"))


        var request = URLRequest(url: URL(string: "http://horn.hostingduty.com/api/v1/app_adduser")!)
        request.httpMethod = "POST"
        print("its working")
        let postString =    "first_name=\(firstNameTextField.text)";
        "last_name=\(lastNameTextField.text)";
        "email_id=\(emailAddressTextField.text)";
        "password=\(passwordTextField.text)"

        request.httpBody = postString.data(using: .utf8)
        let task = URLSession.shared.dataTask(with: request) { data, response, error in
            guard let data = data, error == nil else {                                                 // check for fundamental networking error
                print("error=\(error)")
                return
            }

            if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 {           // check for http errors
                print("statusCode should be 200, but is \(httpStatus.statusCode)")
                print("response = \(response)")
            }



            var responseString = String(data: data, encoding: .utf8)
            print("responseString = \(responseString)")

            if(responseString?.contains("true"))!{

                DispatchQueue.main.async
                    {

                        let homePage = self.storyboard?.instantiateViewController(withIdentifier: "HomePageViewController") as! SWRevealViewController
                        let appDelegate = UIApplication.shared.delegate
                        appDelegate?.window??.rootViewController = homePage

                }

          print("status = true")

            }
            else{

                                DispatchQueue.main.async
                                    {

                                        self.showToast(message: "Already exists !! ")
                                    }
                print("Status = false")

            }
        }

         task.resume()


    }
    func displayMessage(userMessage:String) -> Void {
        DispatchQueue.main.async
            {}
                let alertController = UIAlertController(title: "Alert", message: userMessage, preferredStyle: .alert)

                let OKAction = UIAlertAction(title: "OK", style: .default) { (action:UIAlertAction!) in
                    // Code in this block will trigger when OK button tapped.
                    print("Ok button tapped")
                    DispatchQueue.main.async
                        {
                            self.dismiss(animated: true, completion: nil)
                    }
                }
                alertController.addAction(OKAction)
                self.present(alertController, animated: true, completion:nil)
        }

}

    print(userName)
    let password = passwordText?.text ?? ""
    print(password)
    let params = [

        "emailId"      :  userName as Any,
