ios - taskWillPerformHTTPRedirection 从未被调用

Question

我试图从我的帖子请求中获取重定向链接，但在升级到 alamofire 4.3.0 之后，我的 delegate.taskWillPerformHTTPRedirection 从未调用过。我做错了什么？

我是这样调用的:

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 {}

Answer 1

我的问题:没有使用声明的经理来调用我期望重定向的电话。示例:

 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 {    
}
