Я использую p2 / OAuth2 с Alamofire v4, как описано в документации здесь
let sessionManager = SessionManager()
let retrier = OAuth2RetryHandler(oauth2: <# your OAuth2 instance #>)
sessionManager.adapter = retrier
sessionManager.retrier = retrier
self.alamofireManager = sessionManager // you must hold on to this somewhere
// Note that the `validate()` call here is important
sessionManager.request("https://api.github.com/user").validate().responseJSON { response in
debugPrint(response)
}
import Foundation
import OAuth2
import Alamofire
class OAuth2RetryHandler: RequestRetrier, RequestAdapter {
let loader: OAuth2DataLoader
init(oauth2: OAuth2) {
loader = OAuth2DataLoader(oauth2: oauth2)
}
/// Intercept 401 and do an OAuth2 authorization.
public func should(_ manager: SessionManager, retry request: Request, with error: Error, completion: @escaping RequestRetryCompletion) {
if let response = request.task?.response as? HTTPURLResponse, 401 == response.statusCode, let req = request.request {
var dataRequest = OAuth2DataRequest(request: req, callback: { _ in })
dataRequest.context = completion
loader.enqueue(request: dataRequest)
loader.attemptToAuthorize() { authParams, error in
guard error?.asOAuth2Error != .alreadyAuthorizing else {
// Don't dequeue requests if we are waiting for other authorization request
return
}
self.loader.dequeueAndApply() { req in
if let comp = req.context as? RequestRetryCompletion {
comp(nil != authParams, 0.0)
}
}
}
}
else {
completion(false, 0.0) // not a 401, not our problem
}
}
/// Sign the request with the access token.
public func adapt(_ urlRequest: URLRequest) throws -> URLRequest {
guard nil != loader.oauth2.accessToken else {
return urlRequest
}
return try urlRequest.signed(with: loader.oauth2) // "try" added in 3.0.2
}
}
Все работает нормально, но я хочу избежать 401 ошибка при получении токена доступа, если срок его действия истек перед отправкой запроса.
Возможно ли реализовать этот подход?
Заранее спасибо, С уважением,
