How can I embed an Instagram Video or Picture using SSL?

问题

I need to embed Instagram Video or Photo using the SSL protocol, so I can show it in a facebook app.

If I insert an iframe with the following URL https://instagram.com/p/hvisAyBQZ0/embed/ it will load all resources in http, but not https.

UPDATE:
This is the HTTPS Response, it's a 302 response.

Connection: keep-alive
Content-Length: 154
Content-Type: text/html
Date: Tue, 10 Dec 2013 15:58:20 GMT
Location: http://instagram.com/p/hvisAyBQZ0/embed/
Server: nginx

According to this old Google Groups post by Mike Krieger, you can get the URL via the API, then substitute the beginning of the url with distillery.s3.amazonaws.com.

For example: http://images.ak.instagram.com/profiles/profile_539562_75sq_1386973442.jpg can become //distillery.s3.amazonaws.com/profiles/profile_539562_75sq_1386973442.jpg which works fine on https.

It appears Instagram now uses various CDNs, so you have to be a little smarter with the rewrite rules. Here's my code

def sslify_instagram_cdn_url(url):
    """Intercept IG CDN urls and serve using a SSL-friendly CDN instead"""
    replace_prefixes = (
        ('^http://images.ak.instagram.com(.*)$', '//distillery.s3.amazonaws.com%s'),
        ('^http://distilleryimage([0-9]*).ak.instagram.com(.*)$', '//distilleryimage%s.s3.amazonaws.com%s'),
        ('^http://origincache-([a-z]*).fbcdn.net(.*)$', '//origincache-%s.fbcdn.net%s'),
        ('^http://distilleryimage([0-9]*).s3.amazonaws.com(.*)$', '//distilleryimage%s.s3.amazonaws.com%s'),
        ('^http://scontent-([a-z]).cdninstagram.com(.*)$', '//scontent-%s.cdninstagram.com%s'),
        ('^http://photos-[a-z].ak.instagram.com/hphotos-ak-[0-9a-z]{3,4}/(.*)$', '//origincache-frc.fbcdn.net/%s'),
    )
    for prefix, replacement in replace_prefixes:
        results = re.findall(prefix, url)
        if not results:
            continue
        return replacement % results[0]
    return url

Be warned, this may break when/if Instagram changes their CDN setup. But it's a workable hack for now.

Unfortunately Instagram does not support HTTPS for traditional <iframe> embedding. All they do is respond with a redirect to http as you found out yourself.

Alternatively you could embed the picture itself with an <img> tag. The pictures can be served via HTTPS with a valid SSL certificate.

Examples:

<img src="//instagram.com/p/hvisAyBQZ0/media/?size=t" alt="Thumbnail (150x150)">
<img src="//instagram.com/p/hvisAyBQZ0/media/?size=m" alt="Medium (305x306)">
<img src="//instagram.com/p/hvisAyBQZ0/media/?size=l" alt="Large (640x640)">

All these URLs are actually redirects, but the target URL seems to support HTTPS although it's not mentioned in the official documentation.

This is of course not a satisfying substitute for a regular embed, because Instagram videos cannot be served like this (only the preview images). But maybe it's better than nothing for some.

For this, you'll need to implement Instagram's Developer API.

You will notice that all of their endpoints are available over https, in particular...

https://api.instagram.com/v1/media/3?access_token=[redacted]

...which will retrieve a particular photo or video.

The EFF has a great resource with Instagram cdn rewrite rules in their HTTPS Everywhere Atlas: https://www.eff.org/https-everywhere/atlas/domains/instagram.com.html

Using these you could make a somewhat more robust system for generating instagram https image links.
