我正在尝试在我的API中注册用户。当我在Postman中执行此操作时，它会注册用户并将状态返回为true并将消息作为User Created返回，但是当我尝试以编程方式从swift创建新用户时，它始终显示User已存在（给出错误响应），即使它没有注册。我正在使用Swift 4 Xcode 9。
几乎相同的代码工作适用于登录Api，但不适用于用户注册。此外，在我通过Api中的邮递员注册该用户后，它对于Login非常适用。所以我没有得到RegisterUser的问题。代码显示没有错误。
这是我注册用户的代码：
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 repeatPasswordTextField: UITextField!

您应该在请求中添加标头并发送正确的url编码键/值
request.setValue("application/x-www-form-urlencoded; charset=utf-8", forHTTPHeaderField: "Content-Type");
并将您的帖子字符串更改为
let postString = "first_name=\(firstNameTextField.text)&" +
"last_name=\(lastNameTextField.text)&" +
"email_id=\(emailAddressTextField.text)&" +
"password=\(passwordTextField.text)"
request.httpBody = postString.data(using: .utf8)
UPDATE
func callApi(){
var request = URLRequest(url: URL(string: "http://horn.hostingduty.com/api/v1/app_adduser")!)
request.httpMethod = "post"
request.setValue("application/x-www-form-urlencoded; charset=utf-8", forHTTPHeaderField: "Content-Type")
print("its working")
let postString = "first_name=test&" +
"last_name=test&" +
"[email protected]&" +
"password=123&"
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?.localizedDescription)")
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"))!{
print("status = true")
}
else{
print("Status = false")
}
}
task.resume()
}
