如何从gmail联系人获取朋友个人资料图片？

Question

I'm trying to import GMail contacts (friends list). I have got friends' mail id, name, and phone number, but if I tried to get the images it says "401 error".

The code I have used is as follows:

GDataLink *photoLink = [contact photoLink];
NSLog(@"%@",photoLink);

NSURL *imageURL = [photoLink URL];
NSLog(@"image url = %@",imageURL);

How can I get friends' profile picture? Where did I go wrong?

Looking at some other (public) code that's roughly the same as what you're doing , I see that you should be using an auth token with these photo links. Without that auth token, Google assumes you might be malicious and will send back a 401 error.

EG

    GDataLink *photoLink = [contact photoLink];

    NSString *imageETag = [photoLink ETag];
    if (imageETag == nil || ![mContactImageETag isEqual:imageETag]) {

      if (imageETag != nil) {

        // get an NSURLRequest object with an auth token
        NSURL *imageURL = [photoLink URL];
        GDataServiceGoogleContact *service = [self contactService];

        // requestForURL:ETag:httpMethod: sets the user agent header of the
        // request and, when using ClientLogin, adds the authorization header
        NSMutableURLRequest *request = [service requestForURL:imageURL
                                                         ETag:nil
                                                   httpMethod:nil];

        [request setValue:@"image/*" forHTTPHeaderField:@"Accept"];

        GTMHTTPFetcher *fetcher = [GTMHTTPFetcher fetcherWithRequest:request];
        [fetcher setAuthorizer:[service authorizer]];
        [fetcher beginFetchWithDelegate:self
                 didFinishSelector:@selector(imageFetcher:finishedWithData:error:)];
      }
    }
  }
