AFNetworking setAuthenticationChallengeBlock

Question

我的服务器需要客户端证书,经过一段时间搜索和阅读AFNetworking文档中的示例后,我尝试设置setAuthenticationChallengeBlock并提供客户端证书.

在浏览器提供的certifacete工作正常.

[requestOperation setAuthenticationChallengeBlock:^(NSURLConnection *connection, NSURLAuthenticationChallenge *challenge)
    {
        NSLog(@"AuthenticationChallenge");

        NSString *thePath = [[NSBundle mainBundle] pathForResource:@"client" ofType:@"pfx"];
        NSData *PKCS12Data = [[NSData alloc] initWithContentsOfFile:thePath];
        CFDataRef inPKCS12Data = (__bridge CFDataRef)PKCS12Data;
        SecIdentityRef identity;

        [self extractIdentity:inPKCS12Data :&identity];

        SecCertificateRef certificate = NULL;
        SecIdentityCopyCertificate (identity, &certificate);

        const void *certs[] = {certificate};
        CFArrayRef certArray = CFArrayCreate(kCFAllocatorDefault, certs, 1, NULL);

        NSURLCredential *credential = [NSURLCredential credentialWithIdentity:identity certificates:(__bridge NSArray*)certArray persistence:NSURLCredentialPersistencePermanent];
        [challenge.sender useCredential:credential forAuthenticationChallenge:challenge];
    }];
    [requestOperation start];

但是块中的代码永远不会被调用,服务器会按预期返回403错误.

其他块中的代码,如setUploadBlock等可以正常工作.

知道我的错误在哪里？

今晚我遇到了类似的问题。在进一步调查 AFNetworking 头文件后，我发现了我的问题。我忘记阻止setAuthenticationAgainstProtectionSpaceBlock我的操作了。

    [requestOperation  setAuthenticationAgainstProtectionSpaceBlock:^BOOL(NSURLConnection *connection, NSURLProtectionSpace *protectionSpace) {

        NSLog(@"Auth against protected space [%@]", protectionSpace);

        return YES;

    }];

我相信 AFNetworking 使用此块来处理 NSURLConnectionDelegate 协议方法：- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace。
