AlamoFire不尊重超时间隔

Question

class APIClient {
    var user = User()
    let alamoFireManager : Alamofire.Manager?
    let center = NSNotificationCenter.defaultCenter()


    init(){
        let configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
        configuration.timeoutIntervalForRequest = 4 // seconds
        configuration.timeoutIntervalForResource = 4
        self.alamoFireManager = Alamofire.Manager(configuration: configuration)
    }

    func test(){
        //This does not respect the 4 second time out. Why?
        self.alamoFireManager!.request(.POST, CONSTANTS.APIEndpoint+"/test", parameters: parameters).responseJSON {
                        (req, res, json, error)  in
                        if let json = self.handleAPIResponse(req, res: res, json_data: json, error: error){
                        }
                    }
    }

你确定没有强制执行4秒超时吗？我创建了一个实验:

    let center = NSNotificationCenter.defaultCenter()
    var alamoFireManager : Alamofire.Manager?

    let configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
    configuration.timeoutIntervalForRequest = 4 // seconds
    configuration.timeoutIntervalForResource = 4
    self.alamoFireManager = Alamofire.Manager(configuration: configuration)

    self.alamoFireManager!.request(.POST, "http://oznet.go.ro/iDorMobile/ConfigServer/api.php/timeout/2", parameters: nil).responseJSON {
        (req, res, json, error)  in
        println("First json \(json)")
        println("First error \(error)")
    }

    self.alamoFireManager!.request(.POST, "http://oznet.go.ro/iDorMobile/ConfigServer/api.php/timeout/6", parameters: nil).responseJSON {
        (req, res, json, error)  in
        println("Second \(json)")
        println("Second \(error)")
    }

和我得到的控制台输出:

First json Optional({
    name = timeoutTest;
    value = 2;
})
First error nil
Second nil
Second Optional(Error Domain=NSURLErrorDomain Code=-1001 "The request timed out." UserInfo=0x7f91dc8223e0 {NSErrorFailingURLKey=http://oznet.go.ro/iDorMobile/ConfigServer/api.php/timeout/6, NSLocalizedDescription=The request timed out., NSErrorFailingURLStringKey=http://oznet.go.ro/iDorMobile/ConfigServer/api.php/timeout/6})

我的示例中的URL目前已关闭,我将尝试将它们重新联机.您可以使用示例中的URL进行测试.通过在末尾设置不同的数字,您可以修改超时(以秒为单位).

我使用过cocoapods最后一个版本的Alamofire.

您需要为请求管理器创建一个全局变量:

var alamoFireManager = Alamofire.Manager.sharedInstance

并在配置自定义参数后:

 let configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
    configuration.timeoutIntervalForRequest = 4 // seconds
    configuration.timeoutIntervalForResource = 4
    self.alamoFireManager = Alamofire.Manager(configuration: configuration)

Answer 3

这是Swift 3.0/Alamofire 4.0代码,用于获取具有5秒超时的alamofireManager:

    let configuration = URLSessionConfiguration.default
    configuration.timeoutIntervalForResource = 5 // seconds

    let alamofireManager = Alamofire.SessionManager(configuration: configuration)

Answer 4

我想这个适合你,请注意你必须在函数外面声明Alamofire.Manager的实例,请看下面的代码

//Declare it out side the function
var alamoFireManager : Alamofire.Manager!

func callUrl() {
    let configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
    configuration.timeoutIntervalForResource = 10800 // seconds
    configuration.timeoutIntervalForRequest = 10800 // seconds

    alamoFireManager = Alamofire.Manager(configuration: configuration)

    alamoFireManager.request(.POST, url, parameters: dir as? [String : AnyObject], encoding: .JSON, headers: [ "Content-Type": "application/json"])
        .responseJSON { response in
    }
}

希望这能帮助你
