具有自签名证书的NSURLSession +服务器

我有一个生产的应用程序,以及具有自签名证书的开发服务器

- (void)URLSession:(NSURLSession *)session didReceiveChallenge:(NSURLAuthenticationChallenge *)challenge completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition disposition, NSURLCredential *credential))completionHandler我试图testingNSURLSession和后台下载,但似乎无法通过- (void)URLSession:(NSURLSession *)session didReceiveChallenge:(NSURLAuthenticationChallenge *)challenge completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition disposition, NSURLCredential *credential))completionHandler

当我使用NSURLConnection我可以绕过它使用:

 - (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace { NSLog(@"canAuthenticateAgainstProtectionSpace %@", [protectionSpace authenticationMethod]); return [protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]; } - (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge { NSLog(@"didReceiveAuthenticationChallenge %@ %zd", [[challenge protectionSpace] authenticationMethod], (ssize_t) [challenge previousFailureCount]); [challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge]; } 

但我不知道如何得到这个与NSURLSession > 🙁

这是我目前(这是行不通的):

 - (void)URLSession:(NSURLSession *)session didReceiveChallenge:(NSURLAuthenticationChallenge *)challenge completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition disposition, NSURLCredential *credential))completionHandler { NSLog(@"NSURLSession did receive challenge."); completionHandler(NSURLSessionAuthChallengeUseCredential, [NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust]); } 

我也尝试创build一个NSURLSession的类别,允许主机的任何证书:

 #import "NSURLRequest+IgnoreSSL.h" @implementation NSURLRequest (IgnoreSSL) + (BOOL)allowsAnyHTTPSCertificateForHost:(NSString*)host { return YES; } + (void)setAllowsAnyHTTPSCertificate:(BOOL)allow forHost:(NSString*)host {} @end 

这似乎也没有帮助。


编辑

我已经更新了这个方法来返回:

 - (void)URLSession:(NSURLSession *)session didReceiveChallenge:(NSURLAuthenticationChallenge *)challenge completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition disposition, NSURLCredential *credential))completionHandler { //Creates credentials for logged in user (username/pass) NSURLCredential *cred = [[AuthController sharedController] userCredentials]; completionHandler(NSURLSessionAuthChallengeUseCredential, cred); } 

哪还是什么都不做。

对我来说,你的第一个例子工作正常。 我已经testing了下面的代码没有问题(这当然是非常不安全的,因为它允许任何服务器证书)。

 @implementation SessionTest - (void) startSession { NSURL *url = [NSURL URLWithString:@"https://self-signed.server.url"]; NSURLSessionConfiguration *defaultConfigObject = [NSURLSessionConfiguration defaultSessionConfiguration]; NSURLSession *defaultSession = [NSURLSession sessionWithConfiguration: defaultConfigObject delegate: self delegateQueue: [NSOperationQueue mainQueue]]; NSURLSessionDataTask * dataTask = [defaultSession dataTaskWithURL:url completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) { if(error == nil) { NSString * text = [[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding]; NSLog(@"Data: %@",text); } else { NSLog(@"Error: %@", error); } }]; [dataTask resume]; } - (void)URLSession:(NSURLSession *)session task:(NSURLSessionTask *)task didReceiveChallenge:(NSURLAuthenticationChallenge *)challenge completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition disposition, NSURLCredential *credential))completionHandler { completionHandler(NSURLSessionAuthChallengeUseCredential, [NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust]); } @end 

更新:这是类接口,SessionTest类是NSURLSessionDataDelegate,要启动数据下载你创build一个SessionTest对象并调用startSession方法。

 @interface SessionTest : NSObject <NSURLSessionDelegate> - (void) startSession; @end 

没有足够的信息来为您的问题提出具体的解决scheme。

这里有一些主要要求:

禁用服务器信任评估应按照您在第一个示例中尝试的方式工作。 只用于开发!
