Why I can't use my request adapter interceptor with Alamofire request? - swift

Question

I have such interceptor:
struct EnvInterceptor:RequestInterceptor,RequestRetrier {
let preferences = UserDefaults.standard
func adapt(_ urlRequest: URLRequest, for session: URLSession, completion: #escaping (Result<URLRequest, Error>) -> Void) {
var adaptedRequest = urlRequest
adaptedRequest.addValue("application/json", forHTTPHeaderField: "Content-Type")
guard urlRequest.url?.absoluteString.hasPrefix("/login") == true || urlRequest.url?.absoluteString.hasPrefix("/refresh") == true else {
return completion(.success(urlRequest))
}
if self.preferences.integer(forKey: "expires_in") - Int(Date().timeIntervalSince1970) - self.preferences.integer(forKey: "time_delta")<=60 {
refreshTokens()
}
adaptedRequest.addValue("Bearer " + self.preferences.string(forKey: "access_token")!, forHTTPHeaderField: "Autorization")
print("request")
completion(.success(adaptedRequest))
}
func retry(_ request: Request, for session: Session, dueTo error: Error, completion: #escaping (RetryResult) -> Void) {
}
func refreshTokens(){
print("refresh tokens")
let parameters = ["token": self.preferences.string(forKey: "refresh_token") ?? ""]
var request = URLRequest(url: URL(string: Pathes.init().refreshTokens)!)
request.httpMethod = HTTPMethod.post.rawValue
request.httpBody = try? JSONSerialization.data(withJSONObject: parameters, options: []);
AF.request(request).responseJSON() { response in
switch response.result {
case .success:
guard let data = response.data else {return}
do{
let resp = try JSONDecoder().decode(RefreshToken.self, from: data)
let dfmatter = DateFormatter()
dfmatter.dateFormat="EEE, dd MMM yyyy HH:mm:ss Z"
let date = dfmatter.date(from: response.response?.allHeaderFields["Date"] as! String)
let dateStamp:TimeInterval = date!.timeIntervalSince1970
DispatchQueue.main.async {
self.preferences.set(Int(dateStamp)-Int(Date().timeIntervalSince1970), forKey: "time_delta")
self.preferences.setValue(resp.expires_in, forKey: "expires_in")
self.preferences.setValue(resp.access_token, forKey: "access_token")
self.preferences.setValue(resp.refresh_token, forKey: "refresh_token")
}
}catch{
print(error.localizedDescription)
}
case .failure(let error):
print(error.responseCode as Any)
}
}
}
}
and here I'm trying to use it:
var request = URLRequest(Pathes.init().userInfo! as URL)
request.httpMethod = "GET"
let session = Alamofire.Session(
configuration: URLSessionConfiguration.default,
interceptor: Interceptor(adapters: [EnvInterceptor()]))
session.request(request).responseDecodable(of:PersonalInfo.self){(response) in
print(response.response?.statusCode)
}
and the problem is that I can't see response. I think that I did smth wrong during interceptor building, maybe someone will see where the problem is?

Do you mean to use hasSuffix in this guard clause? Because no url string can have prefixes like "/login".
guard urlRequest.url?.absoluteString.hasPrefix("/login") == true || urlRequest.url?.absoluteString.hasPrefix("/refresh") == true else {
return completion(.success(urlRequest))
}
