如何在 Alamofire 中禁用缓存 [英] How to disable caching in Alamofire

问题描述

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.

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: "http://example.com/wrong_request")!))
        }
    }
}

并使用它:

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