taskWillPerformHTTPRedirection從未調用

Question

我正在嘗試從發布請求中獲取重定向鏈接，但是升級到alamofire 4.3.0之后，我的委托.taskWillPerformHTTPRedirection從未調用過。 我做錯了什么？

我這樣稱呼：

let sessionManager = Alamofire.SessionManager(configuration: URLSessionConfiguration.default)
let delegate: Alamofire.SessionDelegate = sessionManager.delegate

delegate.taskWillPerformHTTPRedirection = { session, task, response, request in
    let headers = response.allHeaderFields
    MYUrlConstant.redirectLocation = headers["Location"]! as! String
    return URLRequest(url: URL(string: MYUrlConstant.redirectLocation)!)
}

Alamofire.request("http://test.com", method: .post, parameters: nil).responseJSON {}

我的問題：沒有使用已聲明的管理器撥打我希望重定向的電話。 例：

 let sessionManager = Alamofire.SessionManager(configuration: URLSessionConfiguration.default)

    let configuration = URLSessionConfiguration.default
    manager = Alamofire.SessionManager(configuration: configuration)
    let delegate: Alamofire.SessionDelegate = SessionDelegate.init()

    manager!.delegate.taskWillPerformHTTPRedirection = { session, task, response, request in
        let headers = response.allHeaderFields
        let redirectLocation = headers["Location"]! as! String
        return URLRequest(url: URL(string: redirectLocation)!)
    }

//make your call with your manager delcared
manager!.request("url", method: .post, parameters: parameters).responseJSON {    
}
