iphone:不调用 didReceiveAuthenticationChallenge 和 canAuthenticateAgainstProtectionSpace 以提供安全的 Restful 服务

Question

我正在尝试从安全的 restful 服务中获取数据。我关注许多其他帖子以及

How to use NSURLConnection to connect with SSL for an untrusted cert?

但在我的例子中，没有调用 didReceiveAuthenticationChallenge 和 canAuthenticateAgainstProtectionSpace。

如果您能解决问题或提供一些调用安全 Restful 服务的好例子，请提供帮助。

 NSURL *url = [NSURL URLWithString:@"https://76.69.53.126:8443/jaxrs/tdgateway/getCountries"];


NSError * error = nil;   
NSMutableURLRequest *urlRequest=[NSMutableURLRequest requestWithURL:url];
[ NSURLConnection sendSynchronousRequest: urlRequest returningResponse: nil error: &error ];

NSLog(@"This is %@",url);




- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace {
    NSLog(@"This is canAuthenticateAgainstProtectionSpace");
    return [protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust];
}

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
{
    NSLog(@"This is didReceiveAuthenticationChallenge");
    [[challenge sender] cancelAuthenticationChallenge:challenge];
}  

Answer 1

它可能与 NSURLAuthenticationMethodServerTrust 不同，因此请先尝试一下:

- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace {
    return YES;
}

您不应该立即取消它:

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
{
    NSLog(@"This is didReceiveAuthenticationChallenge");
    [[challenge sender] cancelAuthenticationChallenge:challenge];
}
