如何在不使用浏览器的情况下使用swift登录Morningstar网站？

Question

我能够进行身份验证，但仍无法使登录工作。登录请求会抛出一个通用的500状态码作为响应。我已经尝试使用session.dataTask（）代替session.uploadTask（）进行登录，但这没有帮助。

我正在尝试将python中的工作代码移植到可可应用程序中-

How can I log in to morningstar.com without using a headless browser such as selenium?

func mornLogin（）{

let authUrl = URL(string: "https://sso.morningstar.com/sso/json/msusers/authenticate")
let loginUrl = URL(string: "https://www.morningstar.com/api/v2/user/login")
let userName = "username"
let passWord = "password"

// Configure URL Session
let session = URLSession(configuration: URLSessionConfiguration.default)

// Prepare Authentication URL Request
var authRequest = URLRequest(url: authUrl!)
authRequest.httpMethod = "POST"
authRequest.addValue("https://www.morningstar.com/members/login.html", forHTTPHeaderField: "Referer")
authRequest.setValue("application/json", forHTTPHeaderField: "Content-Type")
authRequest.addValue(userName, forHTTPHeaderField: "X-OpenAM-Username")
authRequest.addValue(passWord, forHTTPHeaderField: "X-OpenAM-Password")
authRequest.addValue("https://www.morningstar.com", forHTTPHeaderField: "Origin")

let authTask = session.dataTask(with: authRequest) { (data, response, error) in
    if let response = response, let statusCode = (response as? HTTPURLResponse)?.statusCode, statusCode == 200 {
        print("Authentication successful!")

        // Prepare Login URL Request
        struct loginData: Codable {
            var productCode: String
            var rememberMe: Bool
        }

        let encoder = JSONEncoder()
        encoder.outputFormatting = .prettyPrinted
        let jsonBody = try! encoder.encode(loginData(productCode: "DOT_COM", rememberMe: false))
        var loginRequest = URLRequest(url: loginUrl!)
        loginRequest.httpBody = jsonBody
        loginRequest.httpMethod = "POST"

        let loginTask = session.uploadTask(with: loginRequest, from: jsonBody) {
            (data, response, error) in

            if let response = response, let statusCode = (response as? HTTPURLResponse)?.statusCode, statusCode == 200 {
                print("Login successful!")
            }
            else
            {
                print("Login error, response = \(String(describing: response))")
            }
        }
        loginTask.resume()
    }
    else
    {
        print("Authentication error, response = \(String(describing: response))")
    }
}
authTask.resume()

}
