Swift 2- AFNetwork请求缓存问题

Question

我正在使用下面的AFNetworking代码进行联网请求

        let manager = AFHTTPRequestOperationManager()
        manager.requestSerializer.cachePolicy = NSURLRequestCachePolicy.ReturnCacheDataElseLoad
        manager.responseSerializer = AFHTTPResponseSerializer()

        var parameters = Dictionary<String, AnyObject>()
        parameters["key"] = Constants.urlKey


        manager.POST(Constants.categoryProductsUrl,
           parameters: parameters,
        success: { (operation: AFHTTPRequestOperation!, responseObject: AnyObject!) in
            let productAdapter = ProductAdapter()
            productAdapter.mapResponseOnModel(responseObject, error:"", pageLoaded:page, categoryLoaded:categoryId, callback:callback)
        },
        failure: { (operation: AFHTTPRequestOperation?,error: NSError!) in
            print("afnetworking GET producst   - Error: " + error.localizedDescription)
            let productAdapter = ProductAdapter()
            productAdapter.mapResponseOnModel("", error:Constants.ERROR_SOME_THING_WENT_WRONG, pageLoaded:page, categoryLoaded:categoryId, callback:callback)
    })

但是响应没有被缓存，尽管我已经提到了缓存策略如下：

manager.requestSerializer.cachePolicy = NSURLRequestCachePolicy.ReturnCacheDataElseLoad

服务器标头如下

这里最近出现了一个问题：set-cache-time-afnetworking-swift-2

然而，它是在Objective-C中。您可以从obj-c嵌入代码，但是如果您不想回到obj-c，为什么不使用另一个新东西：AlamoFire

AlamoFire中的缓存控制：alamofire-nsurlcache-is-not-working
