Question

我试图获取Picasa的请求令牌以离线访问相册和相片。我能够使用这两个参数（access_type和approval_prompt）从服务器端请求它，但我不知道如何将它们传递给iPhone客户端（GTMOAuth2Authentication和GTMOAuth2ViewControllerTouch）。

ACCESS_TYPE =离线＆安培; approval_prompt =力＆＃34;

非常感谢任何帮助。

谢谢！

Answer 1

找到答案。在发出请求之前，您可以在GTMOAuth2SignIn additionalAuthorizationParameters属性中设置参数。

GTMOAuth2ViewControllerTouch *viewController;

[[viewController signIn] setAdditionalAuthorizationParameters:[NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:@"offline",@"force", nil] forKeys:[NSArray arrayWithObjects:@"access_type",@"approval_prompt", nil]]];

-(void)showGoogleLoginPage{
    SEL finishedSelector = @selector(viewController:finishedWithAuth:error:);
    GTMOAuth2ViewControllerTouch *authViewController =
    [[GTMOAuth2ViewControllerTouch alloc] initWithScope:kGTLAuthScopeDrive
                                               clientID:kClientID
                                           clientSecret:kClientSecret
                                       keychainItemName:userKeyChainName
                                               delegate:self
                                       finishedSelector:finishedSelector];
    NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjects:[NSArray
                                                                              arrayWithObjects:@"offline",@"force",@"en", nil] forKeys:[NSArray arrayWithObjects:@"access_type",@"approval_prompt",@"hl", nil]];

    authViewController.signIn.shouldFetchGoogleUserProfile = YES;
    authViewController.signIn.additionalAuthorizationParameters=params;
    [self presentViewController:authViewController animated:YES completion:nil];
}

希望对你有所帮助..

Google的GTMOAuth2Authentication客户端是否支持授予离线访问权限？
