Set timeout in Alamofire

Question

I am using Alamofire 4.0.1 and I want to set a timeout for my request. I tried the solutions gived in this question:

In the first case

Answer 1

As Matt said the problem is the following

The difference here is that the initialized manager is not owned, and is deallocated shortly after it goes out of scope. As a result, any pending tasks are cancelled.

The solution to this problem was written by rainypixels

import Foundation import Alamofire

class NetworkManager {

    var manager: Manager?

    init() {
        let configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
        manager = Alamofire.Manager(configuration: configuration)
    }
}

And my own version

class APIManager {

    private var sessionManager = Alamofire.SessionManager()

    func requestCards(_ days_range: Int, success: ((_ cards: [CardModel]) -> Void)?, fail: ((_ error: Error) -> Void)?) {
        DispatchQueue.global(qos: .background).async {
            let parameters = ["example" : 1]

            let headers = ["AUTH" : "Example"]

            let configuration = URLSessionConfiguration.default
            configuration.timeoutIntervalForRequest = 10
            self.sessionManager = Alamofire.SessionManager(configuration: configuration)

            self.sessionManager.request(URLs.cards.value, method: .get, parameters: parameters, encoding: URLEncoding.default, headers: headers).responseJSON { (response) in
                switch response.result {
                case .success:
                    //do json stuff
                    guard let json = response.result.value as? [String : Any] else { return }
                    guard let result = json["result"] as? [[String : Any]] else { return }
                    let cards = Mapper<CardModel>().mapArray(JSONArray: result)
                    debugPrint("cards", cards.count)
                    success?(cards)
                case .failure(let error):
                    if error._code == NSURLErrorTimedOut {
                        //timeout here
                        debugPrint("timeOut")
                    }
                    debugPrint("\n\ncard request failed with error:\n \(error)")
                    fail?(error)
                }
            }
        }
    }
}

Can also make a manager for it

import Alamofire

struct AlamofireAppManager {

    static let shared: SessionManager = {
        let configuration = URLSessionConfiguration.default
        configuration.timeoutIntervalForRequest = 10
        let sessionManager = Alamofire.SessionManager(configuration: configuration)
        return sessionManager
    }()

}

Please Try this:-

    let request = NSMutableURLRequest(url: URL(string: "")!)
    request.httpMethod = "POST"
    request.setValue("application/json", forHTTPHeaderField: "Content-Type")
    request.timeoutInterval = 10 // 10 secs
    let values = ["key": "value"]
    request.httpBody = try! JSONSerialization.data(withJSONObject: values, options: [])
    Alamofire.request(request as! URLRequestConvertible).responseJSON {
        response in
        // do whatever you want here
    }

Answer 3

If you don't want to build a UrlRequest yourself, you can still use Alamofire to build it.

    // set this flag to false so the request will not be sent until
    // resume() is called
    sessionManager.startRequestsImmediately = false

    var urlRequest = sessionManager.request(url,
                                            method: method,
                                            parameters: params,
                                            encoding: encoding,
                                            headers: allHeaders).request!

    urlRequest.timeoutInterval = 10

    let request = sessionManager.request(urlRequest).responseJSON { (result) in
        // use the result
    }

    // need to start the request
    request.resume()

Answer 4

Try this:

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

Swift 3.0

    let configuration = URLSessionConfiguration.default
    configuration.timeoutIntervalForRequest = 4 // seconds
    configuration.timeoutIntervalForResource = 4
    self.alamoFireManager = Alamofire.SessionManager(configuration: configuration)

Answer 5

I have same problem too, I think I found the solution. Try to declare SessionManager?or in your case alamofireManager in class, outside the function

class ViewController: UIViewController {
   var alamoFireManager : SessionManager? // this line

   func alamofire(){
        let configuration = URLSessionConfiguration.default
        configuration.timeoutIntervalForRequest = 10
        configuration.timeoutIntervalForResource = 10
        alamoFireManager = Alamofire.SessionManager(configuration: configuration) // not in this line

        alamoFireManager.request("my_url", method: .post, parameters: parameters).responseJSON { response in


        switch (response.result) {
        case .success:
                 //Success....
            break
        case .failure(let error):
               // failure...
             break
       }
     }
   }

}

Alamofire 5.1 includes a new way to modify the request with a closure in the initializer:

AF.request(url) { $0.timeoutInterval = 60 }
    .validate()
    .response { _ in // handle response here }
