Question

我尝试使用NSURLSession，但现在我想使用Alamofire。

Answer 1

这种方法对我来说非常有用3

 let manager : SessionManager = {
        let config = URLSessionConfiguration.default
            config.timeoutIntervalForRequest = 15
            config.timeoutIntervalForResource = 15
        let mgr = Alamofire.SessionManager(configuration: config)

        return mgr
    }()

Answer 2

在AppDelegate的application(_:didFinishLaunchingWithOptions:)方法中调用此函数。

func configureAlamofire() {
    Alamofire.SessionManager.default.session.configuration.timeoutIntervalForRequest = 15 // in seconds
    Alamofire.SessionManager.default.session.configuration.timeoutIntervalForResource = 15 // in seconds
}

Answer 3

如果您想要自定义超时，请在请求中设置值，或使用自定义配置创建自定义URLSession：alamofire documentation

let configuration = URLSessionConfiguration.default
configuration.timeoutIntervalForRequest = 10 // seconds
configuration.timeoutIntervalForResource = 10
let sessionManager = Alamofire.SessionManager(configuration: configuration)

// OR

var request = URLRequest(url: URL(string: "myApi.com/Api/login")!, cachePolicy: .useProtocolCachePolicy, timeoutInterval: 20)
request.httpMethod = "GET"
request.setValue("application/json", forHTTPHeaderField: "Content-Type")

Alamofire.request("https://httpbin.org/get").responseJSON { response in
    print(response)
    if let json = response.result.value {
        print("JSON: \(json)")
    }
}

Answer 4

let manager = Alamofire.SessionManager.default
manager.session.configuration.timeoutIntervalForRequest = 120

manager.request("yourUrl", method: .post, parameters: ["parameterKey": "value"])
        .responseJSON {
            response in
            switch (response.result) {
            case .success:
                //do json stuff
                break
            case .failure(let error):
                if error._code == NSURLErrorTimedOut {
                    //timeout here
                }
                print("\n\nAuth request failed with error:\n \(error)")
                break
            }
        }

对于Alamofire的新版本（5.0.0以上），这样写，

AF.sessionConfiguration.timeoutIntervalForRequest = 120
AF.sessionConfiguration.timeoutIntervalForResource = 120

如何在alamofire中设置请求超时？
