NSURLConnection and Basic HTTP Authentication in iOS
I'm using an asynchronous connection with MGTwitterEngine and it sets the authorization in the NSMutableURLRequest
(theRequest
) like so:
NSString *authStr = [NSString stringWithFormat:@"%@:%@", [self username], [self password]];
NSData *authData = [authStr dataUsingEncoding:NSASCIIStringEncoding];
NSString *authValue = [NSString stringWithFormat:@"Basic %@", [authData base64EncodingWithLineLength:80]];
[theRequest setValue:authValue forHTTPHeaderField:@"Authorization"];
I don't believe this method requires going through the challenge loop but I could be wrong
Even the question is answered, I want to present the solution, which doesn't require external libs, I found in another thread:
// Setup NSURLConnection
NSURL *URL = [NSURL URLWithString:url];
NSURLRequest *request = [NSURLRequest requestWithURL:URL
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:30.0];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
[connection start];
[connection release];
// NSURLConnection Delegates
- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge {
if ([challenge previousFailureCount] == 0) {
NSLog(@"received authentication challenge");
NSURLCredential *newCredential = [NSURLCredential credentialWithUser:@"USER"
password:@"PASSWORD"
persistence:NSURLCredentialPersistenceForSession];
NSLog(@"credential created");
[[challenge sender] useCredential:newCredential forAuthenticationChallenge:challenge];
NSLog(@"responded to authentication challenge");
}
else {
NSLog(@"previous authentication failure");
}
}
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {
...
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
...
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
...
}
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error {
...
}
