Wie sende ich authentifizierte Anfragen an Google Reader?

Frage
Es scheint, dass Google die alte Art, Cookie SID an seine Google Data -Dienste zu senden, insbesondere Google Reader, deaktiviert hat.
Diesen Weg funktioniert zumindest für mich nicht:
//create request
NSString* content = [NSString stringWithFormat:@"accountType=HOSTED_OR_GOOGLE&Email=%@&Passwd=%@&service=ah&source=myapp", [loginView username].text, [loginView password].text];
NSURL* authUrl = [NSURL URLWithString:@"https://www.google.com/accounts/ClientLogin"];
NSMutableURLRequest* authRequest = [[NSMutableURLRequest alloc] initWithURL:authUrl];
[authRequest setHTTPMethod:@"POST"];
[authRequest setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-type"];
[authRequest setHTTPBody:[content dataUsingEncoding:NSASCIIStringEncoding]];
NSHTTPURLResponse* authResponse;
NSError* authError;
NSData * authData = [NSURLConnection sendSynchronousRequest:authRequest returningResponse:&authResponse error:&authError];
NSString *authResponseBody = [[NSString alloc] initWithData:authData encoding:NSASCIIStringEncoding];
//loop through response body which is key=value pairs, seperated by \n. The code below is not optimal and certainly error prone.
NSArray *lines = [authResponseBody componentsSeparatedByString:@"\n"];
NSMutableDictionary* token = [NSMutableDictionary dictionary];
for (NSString* s in lines) {
NSArray* kvpair = [s componentsSeparatedByString:@"="];
if ([kvpair count]>1)
[token setObject:[kvpair objectAtIndex:1] forKey:[kvpair objectAtIndex:0]];
}
//if google returned an error in the body [google returns Error=Bad Authentication in the body. which is weird, not sure if they use status codes]
if ([token objectForKey:@"Error"]) {
//handle error
};
Und die Anfrage:
TTURLRequest *request = [TTURLRequest requestWithURL:url delegate:self];
request.cachePolicy = cachePolicy;
request.cacheExpirationAge = TT_CACHE_EXPIRATION_AGE_NEVER;
NSString *cookieHeader = [NSString stringWithFormat:@"Name=SID;SID=%@;Domain=.google.com;Path=/;Expires=160000000000", sid];
[request setValue:cookieHeader forHTTPHeaderField:@"Cookie"];
[request setHttpMethod:@"GET"];
[request setValue:@"myapp" forHTTPHeaderField:@"User-agent"];
Wechseln zur Verwendung des Googlelogin Auth = xxx gibt mir einen NsurLrordomain 401
TTURLRequest *request = [TTURLRequest requestWithURL:url delegate:self];
request.cachePolicy = cachePolicy;
request.cacheExpirationAge = TT_CACHE_EXPIRATION_AGE_NEVER;
NSString *authorizationHeader = [NSString stringWithFormat:@"GoogleLogin auth=%@", auth];
[request setValue:authorizationHeader forHTTPHeaderField:@"Authorization"];
[request setHttpMethod:@"GET"];
[request setValue:@"myapp" forHTTPHeaderField:@"User-agent"];
Das Ergebnis ist immer der 401 -Fehlercode. Könnte mir jemand zeigen, wie ich in diesem speziellen Fall behoben werden kann? Danke im Voraus.
Error Domain=NSURLErrorDomain Code=401 "Operation could not be completed. (NSURLErrorDomain error 401.)"
Error description: Operation could not be completed. (NSURLErrorDomain error 401.)
Lösung
Das Ändern des Körpers des Pfostens löst den 401 -Fehler. Unterschiede sind in der service
, source
& continue
.
NSString* content = [NSString stringWithFormat:@"Email=%@&Passwd=%@&service=reader&source=yourapp&continue=http://www.google.com", username, password];
