当我使用 Alamofire 发送两次 GET 请求时，我得到相同的响应，但我期待不同的响应.我想知道是不是因为缓存，如果是，我想知道如何禁用它.

When I send a GET request twice with Alamofire I get the same response but I'm expecting a different one. I was wondering if it was because of the cache, and if so I'd like to know how to disable it.

推荐答案

swift 3, alamofire 4

swift 3, alamofire 4

我的解决方案是:

为 Alamofire 创建扩展:

creating extension for Alamofire:

extension Alamofire.SessionManager{ @discardableResult open func requestWithoutCache( _ url: URLConvertible, method: HTTPMethod = .get, parameters: Parameters? = nil, encoding: ParameterEncoding = URLEncoding.default, headers: HTTPHeaders? = nil)// also you can add URLRequest.CachePolicy here as parameter -> DataRequest { do { var urlRequest = try URLRequest(url: url, method: method, headers: headers) urlRequest.cachePolicy = .reloadIgnoringCacheData // <<== Cache disabled let encodedURLRequest = try encoding.encode(urlRequest, with: parameters) return request(encodedURLRequest) } catch { // TODO: find a better way to handle error print(error) return request(URLRequest(url: URL(string: "example/wrong_request")!)) } } }

并使用它:

Alamofire.SessionManager.default .requestWithoutCache("google/").response { response in print("Request: (response.request)") print("Response: (response.response)") print("Error: (response.error)") }
