问题 I am using Thunderbird as my primary work mail client. I have just created a new HTML signature, which shows correctly in the Thunderbird, in Opera and in an online HTML Viewer but not on GMail. I would be very grateful if anyone could point me in the direction of what the problem is about. I have attached the .html signature file.

问题 Is there any library in Ruby that generates the Signature, 'X-PAYPAL-AUTHORIZATION' header that is required to make calls on behalf of the account holder who has authorized us through the paypal Permissions API. I am done with the permissions flow and get the required access token, tokenSecret.

They give the following errors: For NVP call I get: You do not have permissions to
