每个人的好日子,
我正在研究应该通过互联网管理内容下载的单例,我知道存在ASIHttp请求,这是一个很好的库,但我有自己的理由不使用它。
这个类工作得非常好,除了一件事:我正在尝试处理我的MobileMe帐户的公共文件夹而没有成功。我在其中上传了一个文件并尝试使用我的班级下载。
阅读有关stackOF和阅读文档的一些问题我进入了该代码,但它似乎不起作用:
- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace
{
if([protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust])
{
NSLog(@"SERVER TRUST AUTH");
return YES;
}
else if([protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodHTTPBasic])
{
NSLog(@"HTTP BASIC AUTH");
return YES;
}
NSLog(@"NO AUTH");
return NO;
}
- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
{
NSLog(@"Authetication");
if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust])
{
NSLog(@"Trust Challange");
SecTrustResultType trustResultType;
OSStatus err=SecTrustEvaluate(challenge.protectionSpace.serverTrust, &trustResultType);
NSLog(@"SecTrustResult %lu %ld",trustResultType,err);
if (trustResultType == kSecTrustResultProceed || trustResultType == kSecTrustResultConfirm || trustResultType == kSecTrustResultUnspecified) {
[challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge];
}
else{
[challenge.sender cancelAuthenticationChallenge:challenge];
}
// [challenge.sender continueWithoutCredentialForAuthenticationChallenge:challenge];
}
else if([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodHTTPBasic])
{
NSLog(@"HTTP Challenge");
NSURLCredential *credential = [[NSURLCredential alloc] initWithUser:@"user" password:@"pass" persistence:NSURLCredentialPersistenceForSession];
[[challenge sender] useCredential:credential forAuthenticationChallenge:challenge];
[credential release];
}
else{
[[challenge sender]cancelAuthenticationChallenge:challenge];
}
}
现在我被卡住了,因为从日志中我可以看到evaluate函数返回的结果为4,对应于kSecTrustResultUnspecified,但即使我对挑战发件人说continueWithoutCredentialForAuthenticationChallenge
,也没有任何工作。
该文件的URL是:https://public.me.com/XXXX/Objective.zip(已删除链接)zip是我在课堂上实现的ObjectiveZip库。
有什么建议吗?
