Alamofire-NSURLCache无法正常工作？ [英] Alamofire - NSURLCache is not working?

问题描述

我将缓存设置如下

var cacheSizeMemory = 20 * 1024 * 1024
var cacheSizeDisk = 100 * 1024 * 1024
var sharedCache = NSURLCache(memoryCapacity: cacheSizeMemory, diskCapacity: cacheSizeDisk, diskPath: "SOME_PATH")
NSURLCache.setSharedURLCache(sharedCache)

使用缓存策略创建请求

var request = NSMutableURLRequest(URL: NSURL(string: "\(baseUrl!)\(path)")!, cachePolicy: .ReturnCacheDataElseLoad, timeoutInterval: timeout)

通过以下 Cache-Control private，max-age = 60

然后尝试检查缓存

var cachedResponse = NSURLCache.sharedURLCache().cachedResponseForRequest(urlRequest)

值是nil

有什么想法吗？

推荐答案

我最终手动添加了 Ca che-Control 作为我的请求标头中的 private ，现在可以使用了。甚至不需要手动检查缓存，Alamofire会为您完成

I ended up manually adding Cache-Control as private in the header of my request and it now works. Don't even need to manually check the cache, Alamofire does it for you

let cachePolicy: NSURLRequestCachePolicy = isReachable() ? .ReloadIgnoringLocalCacheData : .ReturnCacheDataElseLoad

var request = NSMutableURLRequest(URL: NSURL(string: "\(baseUrl!)\(path)")!, cachePolicy: cachePolicy, timeoutInterval: timeout)

request.addValue("private", forHTTPHeaderField: "Cache-Control")

var alamoRequest = Manager.sharedInstance.request(urlRequest)
