我有以下代码(
swift实现)：
func connection(connection: NSURLConnection,canAuthenticateAgainstProtectionSpace protectionSpace: NSURLProtectionSpace) -> Bool
{
return protectionSpace.authenticationMethod == NSURLAuthenticationMethodServerTrust
}
func connection(connection: NSURLConnection,didReceiveAuthenticationChallenge challenge: NSURLAuthenticationChallenge)
{
if challenge.protectionSpace.authenticationMethod == NSURLAuthenticationMethodServerTrust
{
if challenge.protectionSpace.host == "myDomain"
{
let credentials = NSURLCredential(forTrust: challenge.protectionSpace.serverTrust)
challenge.sender.useCredential(credentials,forAuthenticationChallenge: challenge)
}
}
challenge.sender.continueWithoutCredentialForAuthenticationChallenge(challenge)
}
它在iOS 8.x中完美地工作,但不工作iOS 7.x
在iOS 7.x我有错误：
NSURLConnection / CFURLConnection HTTP加载失败(kcfStreamErrorDomainSSL,-9813)
任何想法？
谢谢！！！
解决方法
两个连接：canAuthenticateAgainstProtectionSpace：和连接：didReceiveAuthenticationChallenge：在iOS 8中已被弃用,所以你应该使用其他方法.
我在项目中使用的是NSURLSessionDelegate的委托方法.坚持那个协议,然后添加这个方法：
func URLSession(session: NSURLSession,didReceiveChallenge challenge: NSURLAuthenticationChallenge,completionHandler: (NSURLSessionAuthChallengeDisposition,NSURLCredential!) -> Void) {
completionHandler(NSURLSessionAuthChallengeDisposition.UseCredential,NSURLCredential(forTrust: challenge.protectionSpace.serverTrust))
}
然后,当您使用委派设置为self时,初始化NSURLSession.例如：
var session = NSURLSession(configuration: configuration,delegate: self,delegateQueue:NSOperationQueue.mainQueue())
然后使用该会话实例调用dataTaskWithRequest方法：
var task = session.dataTaskWithRequest(request){
(data: NSData!,response: NSURLResponse!,error: NSError!) -> Void in
if error != nil {
callback("",error.localizedDescription)
} else {
var result = NSString(data: data,encoding:
NSASCIIStringEncoding)!
}
}
task.resume()
完整的工作实例可以找到here.
出于安全考虑,如果您使用自签名证书,我建议同时执行公钥固定(https://gist.github.com/edwardmp/df8517aa9f1752e73353)
