最近我一直在尝试使用自签名SSL证书连接到我的测试服务器，使用NSURLSession.sharedSession().dataTaskWithRequest()
现在我收到此错误：
The certificate for this server is invalid. You might be connecting to a server that is pretending to be “...” which could put your confidential information at risk.
我一直在网上搜索如何解决它。他们都建议使用以下之一：
func connection(connection: NSURLConnection, canAuthenticateAgainstProtectionSpace protectionSpace: NSURLProtectionSpace) -> Bool
func connection(connection: NSURLConnection, didReceiveAuthenticationChallenge challenge: NSURLAuthenticationChallenge)
func connection(connection: NSURLConnection, willSendRequestForAuthenticationChallenge challenge: NSURLAuthenticationChallenge)
func URLSession(session: NSURLSession, didReceiveChallenge challenge: NSURLAuthenticationChallenge, completionHandler: (NSURLSessionAuthChallengeDisposition, NSURLCredential!) -> Void)
现在，当我运行我的应用程序时，我注意到只有
func connection(connection: NSURLConnection, willSendRequestForAuthenticationChallenge challenge: NSURLAuthenticationChallenge)
跑。
这是我的代码：
func connection(connection: NSURLConnection, willSendRequestForAuthenticationChallenge challenge: NSURLAuthenticationChallenge)
{
// Trusting and not trusting connection to host: Self-signed certificate
challenge.sender.useCredential(NSURLCredential(forTrust: challenge.protectionSpace.serverTrust), forAuthenticationChallenge: challenge)
challenge.sender.continueWithoutCredentialForAuthenticationChallenge(challenge)
if(challenge.protectionSpace.authenticationMethod == NSURLAuthenticationMethodServerTrust)
{
let trust = challenge.protectionSpace.serverTrust
let cred = NSURLCredential(forTrust: trust)
challenge.sender.useCredential(cred, forAuthenticationChallenge: challenge)
}
}
然而我一直在NSURLConnection/CFURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9813).
啊哈！显然我之前有过一次我没有注意到的let urlConnection = NSURLConnection(request: request, delegate: self)......
我改变了NSURLSession.sharedSession().dataTaskWithRequest()自
let task = NSURLSession(configuration: NSURLSessionConfiguration.defaultSessionConfiguration(), delegate: self, delegateQueue: NSOperationQueue.mainQueue()).dataTaskWithRequest(request)
并保留了委托方法...那做到了:)
