问题
Have created an app to retrieve instagram images from a Twitter rest feed.
Normally it works but occassionally get an 'access denied' message from the Instagram CDN.
For instance

Does anyone know a way to circumvent this?
Am using Adobe AIR for the app.
回答1:
The instagram image urls can get moved around on s3, changed, or deleted at any time. You cannot circumvent this, but rather you can do one of the following:
- Subscribe to the user/tag you are interested in and process the updates accordingly.
- Build a polling mechanism to periodically update your data to supplement #1
Also, I've observed this happening for users who make their feed private. I believe you can follow them to get access if they approve or you're able to authenticate them using their OAuth token. Interestingly, if you know a tag that they've used, the tag endpoints don't respect this privacy at all.
