Picasaweb API Authorization. We get a constant token
I bring to your attention the registration script on the picasaweb web service.
The API of this web service is quite powerful, and is a good helper for photographers and developers.
To date, there are lots of different libraries to work with the picasaweb API. But what if I need to use only a small part of the capabilities of this service? You can use existing libraries (despite their cumbersomeness), redo them for yourself, or write your own bicycle. I am a supporter of my two-wheeled solutions.
The script is elementary, but will require the connection of the curl library. I hope you have it installed and activated, otherwise we will not see good luck.
Let me remind you that in order to receive a token, we need to send a request to the Google server with our data, go through the resolving link confirming the intention, and get the token (temporary) parameter from the het answer, exchange it to a permanent one by sending another request to the chicken.
This will be enough to get a constant token.
')
Then our hands are untied. Now, having this token and your account on this service, we can, for example, display the photos of the album.
Demonstration
$ user, $ album_id and $ key (constant token) I substituted my own. You will have yours.
That's all. Thanks for attention.
