ios - Swift 2 - AFNetwork 请求缓存问题

Question

我正在使用下面的 AFNetworking 代码进行网络请求

        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，即使我已经提到缓存策略如下:

manager.requestSerializer.cachePolicy = NSURLRequestCachePolicy.ReturnCacheDataElseLoad

服务器 header 如下

最近这里出现的问题: set-cache-time-afnetworking-swift-2

但是，它是在 Objective-C 中。您可以从 obj-c 嵌入代码，但如果您不想回到 obj-c，为什么不使用其他新东西: AlamoFire

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