我有以下简单的代码连接到SSL网页
NSMutableURLRequest *urlRequest=[NSMutableURLRequest requestWithURL:url];
[ NSURLConnection sendSynchronousRequest: urlRequest returningResponse: nil error: &error ];
除非它给出一个错误，如果证书是自签名的一个错误域=NSURLErrorDomain Code=-1202 UserInfo=0xd29930“不受信任的服务器证书”。有没有一种方法来设置它接受连接(就像在浏览器中你可以按accept)或一种方法来绕过它?

这不是我的功劳，但我发现这个真的很适合我的需要。shouldAllowSelfSignedCert是我的BOOL变量。只需添加到你的NSURLConnection委托，你应该是rockin快速绕过每个连接的基础上。
- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)space {
if([[space authenticationMethod] isEqualToString:NSURLAuthenticationMethodServerTrust]) {
if(shouldAllowSelfSignedCert) {
return YES; // Self-signed cert will be accepted
} else {
return NO; // Self-signed cert will be rejected
}
// Note: it doesn't seem to matter what you return for a proper SSL cert
// only self-signed certs
}
// If no other authentication is required, return NO for everything else
// Otherwise maybe YES for NSURLAuthenticationMethodDefault and etc.
return NO;
}

我发布了一些要点代码(基于别人的工作，我注意到)，可以让你正确地验证自己生成的证书(以及如何获得免费证书-见Cocoanetics底部的评论)
我的代码在这里github
有一个支持的API来完成这个!在你的NSURLConnection委托中添加如下内容:
- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace {
return [protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust];
}
- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge {
if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust])
if ([trustedHosts containsObject:challenge.protectionSpace.host])
[challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge];
[challenge.sender continueWithoutCredentialForAuthenticationChallenge:challenge];
}
注意connection:didReceiveAuthenticationChallenge:可以将其消息发送给challenge。发送方(很久以后)，在必要时向用户呈现对话框之后，等等。
与AFNetworking我已经成功地消费https webservice与以下代码，
NSString *aStrServerUrl = WS_URL;
// Initialize AFHTTPRequestOperationManager...
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
[manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
manager.securityPolicy.allowInvalidCertificates = YES;
[manager POST:aStrServerUrl parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject)
{
successBlock(operation, responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
errorBlock(operation, error);
}];
如果你想继续使用sendSynchronousRequest，我在这个解决方案:
FailCertificateDelegate *fcd=[[FailCertificateDelegate alloc] init];
NSURLConnection *c=[[NSURLConnection alloc] initWithRequest:request delegate:fcd startImmediately:NO];
[c setDelegateQueue:[[NSOperationQueue alloc] init]];
[c start];
NSData *d=[fcd getData];
