비공인(https) 접속하기

출처:http://kka7.tistory.com/56

인증서가 유효하지 않은 서버(https)에 접속하게 되면 다음과 같은 error 메시지를 볼수 있다.

The certificate for this server is invalid. You might be connecting to a server that is pretending to be “서버주소” which could put your confidential information at risk.

이럴때 임의로 통과시켜 주기 위해서는 다음과 같이 URLSessionDelegate에서 작업을 해주면 된다.

extension HTTPManager: URLSessionDelegate { 
    func urlSession(_ session: URLSession, didReceive challenge: URLAuthenticationChallenge, completionHandler: @escaping (URLSession.AuthChallengeDisposition, URLCredential?) -> Swift.Void) { 
        if challenge.previousFailureCount > 0 { 
            completionHandler(.cancelAuthenticationChallenge, nil) 
        } else if let serverTrust = challenge.protectionSpace.serverTrust { 
            completionHandler(.useCredential, URLCredential(trust: serverTrust)) 
        } else { 
            print("unknown state. error: \(challenge.error)") 
            completionHandler(.performDefaultHandling, nil) 
        } 
    } 
}
