【问题描述】:
我在 iOS 编程中遇到了一些身份验证问题。我有一个代码可以在 Windows 2003 上完美地对抗 IIS6,但不能在带有 IIS7 的 Windows Server 2008 上工作。两台服务器上的安全选项相同(无匿名访问和“集成 Windows 身份验证”)。
这是“didReceiveAuthenticationChallenge”委托的代码:
-(void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:
(NSURLAuthenticationChallenge *)challenge
{
//USE STORED CREDENTIALS
Credentials* cred = [[Credentials alloc] init];
NSString* userName = cred.userName;
NSString* pass = cred.pass;
NSString* authMethod = [[challenge protectionSpace] authenticationMethod];
//Kerberos (Negotiate) needs "user@realm" as username
//NTLM Needs domain\\username
if ([authMethod isEqualToString:NSURLAuthenticationMethodNTLM]) {
userName = [NSString stringWithFormat:@"%@%@", @"es\\" , userName];
}
if ([authMethod isEqualToString:NSURLAuthenticationMethodNegotiate]) {
userName = [NSString stringWithFormat:@"%@%@", userName, @"@subdomain.domain.com"];
}
NSLog(@"Auth method in use: %@" , authMethod);
NSLog(@"User: %@" , userName);
NSLog(@"Pass: %@" , pass);
if ([challenge previousFailureCount] <= 1) {
NSLog(@"received authentication challenge");
NSURLCredential *credential;
credential = [NSURLCredential
credentialWithUser:userName
password:pass
persistence:NSURLCredentialPersistenceForSession];
[[challenge sender] useCredential:credential forAuthenticationChallenge:challenge];
}
else {
NSLog(@"Authentication error");
NSLog(@"Failed login with status code: %d", [(NSHTTPURLResponse*)[challenge failureResponse]statusCode]);
[[challenge sender] cancelAuthenticationChallenge:challenge];
}
}
【问题讨论】:
-
didReceiveAuthenticationChallenge方法是否被调用? -
是的,它被调用了,我可以在那里放置一些断点(并且代码可以从 W2003 服务器工作)
-
“不幸的是”我没有看到你的 iOS 方法有什么不寻常的地方。是否有机会调查质询响应是否返回服务器,如果返回,那里会发生什么?
