如何在Alamofire中禁用缓存
当我使用Alamofire两次发送GET请求时,我得到的响应是相同的,但是我期望得到不同的响应。我想知道这是否是由于缓存造成的,如果是这样,我想知道如何禁用它。

迅捷3,alamofire 4
我的解决方案是:
为Alamofire创建扩展:
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)")
}
