问题
I'm am looking for the MediaID of an Instagram image which has been uploaded. It should look like
1234567894561231236_33215652
I have found out the last set of integers are the usersID
For example: this is the link for the image directly, however I see no mediaID in the correct format?
http://distilleryimage11.ak.instagram.com/d33aafc8b55d11e2a66b22000a9f09de_7.jpg
while this is the link
http://instagram.com/p/Y7GF-5vftL/
I don't wish to use the API as all I need the MediaID from a selected image.

So the most up-voted "Better Way" is a little deprecated so here is my edit and other solutions:
Javascript + jQuery
$.ajax({
type: 'GET',
url: 'http://api.instagram.com/oembed?callback=&url='+Url, //You must define 'Url' for yourself
cache: false,
dataType: 'json',
jsonp: false,
success: function (data) {
var MediaID = data.media_id;
}
});
PHP
$your_url = "" //Input your url
$api = file_get_contents("http://api.instagram.com/oembed?callback=&url=" . your_url);
$media_id = json_decode($api,true)['media_id'];
So, this is just an updated version of @George's code and is currently working. However, I made other solutions, and some even avoid an ajax request:
Shortcode Ajax Solution
Certain Instagram urls use a shortened url syntax. This allows the client to just use the shortcode in place of the media id if requested properly.
An example shortcode url looks like this: https://www.instagram.com/p/Y7GF-5vftL/
The Y7GF-5vftL is your shortcode for the picture.
Using Regexp:
var url = "https://www.instagram.com/p/Y7GF-5vftL/"; //Define this yourself
var Key = /p\/(.*?)\/$/.exec(url)[1];
In the same scope, Key will contain your shortcode. Now to request, let's say, a low res picture using this shortcode, you would do something like the following:
$.ajax({
type: "GET",
dataType: "json",
url: "https://api.instagram.com/v1/media/shortcode/" + Key + "?access_token=" + access_token, //Define your 'access_token'
success: function (RawData) {
var LowResURL = RawData.data.images.low_resolution.url;
}
});
There is lots of other useful information, including the media id, in the returned RawData structure. Log it or look up the api documentation to see.
Shortcode Conversion Solution
You can actually convert your shortcode to the id fairly easily! Here's a simple way to do it in javascript:
function shortcodeToInstaID(Shortcode) {
var char;
var id = 0;
var alphabet = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789-_';
for (var i = 0; i < Shortcode.length; i++) {
char = Shortcode[i];
id = (id * 64) + alphabet.indexOf(char);
}
return id;
}
Note: If you want a more robust node.js solution, or want to see how you would convert it back, check out @Slang's module on npm.
Full Page Solution
So what if you have the URL to a full Instagram page like: https://www.instagram.com/p/BAYYJBwi0Tssh605CJP2bmSuRpm_Jt7V_S8q9A0/
Well, you can actually read the HTML to find a meta property that contains the Media ID. There are also a couple other algorithms you can perform on the URL itself to get it, but I believe that requires too much effort so we will keep it simple. Either query the meta tag al:ios:url or iterate through the html. Since reading metatags is posted all over, I'll show you how to iterate.
NOTE: This is a little unstable and is vulnerable to being patched. This method does NOT work on a page that uses a preview box. So if you give it the current HTML when you click on a picture in someone's profile, this WILL break and return a bad Media ID.
function getMediaId(HTML_String) {
var MediaID = "";
var e = HTML_String.indexOf("al:ios:url") + 42; //HTML_String is a variable that contains all of the HTML text as a string for the current document. There are many different ways to retrieve this so look one up.
for (var i = e; i <= e + 100; i++) { //100 should never come close to being reached
if (request.source.charAt(i) == "\"")
break;
MediaID += request.source.charAt(i);
}
return MediaID;
}
And there you go, a bunch of different ways to use Instagram's api to get a Media ID. Hope one fixes your struggles.

Here's a better way:
http://api.instagram.com/oembed?url=http://instagram.com/p/Y7GF-5vftL/
Render as json object and you can easily extract media id from it ---
For instance, in PHP
$api = file_get_contents("http://api.instagram.com/oembed?url=http://instagram.com/p/Y7GF-5vftL/");
$apiObj = json_decode($api,true);
$media_id = $apiObj['media_id'];
For instance, in JS
$.ajax({
type: 'GET',
url: 'http://api.instagram.com/oembed?callback=&url=http://instagram.com/p/Y7GF-5vftL/',
cache: false,
dataType: 'jsonp',
success: function(data) {
try{
var media_id = data[0].media_id;
}catch(err){}
}
});

Here's an even better way:
No API calls! And I threw in converting a media_id to a shortcode as an added bonus.
Based on slang's amazing work for figuring out the conversion. Nathan's work converting base10 to base64 in php. And rgbflawed's work converting it back the other way (with a modified alphabet). #teameffort
function mediaid_to_shortcode($mediaid){
if(strpos($mediaid, '_') !== false){
$pieces = explode('_', $mediaid);
$mediaid = $pieces[0];
$userid = $pieces[1];
}
$alphabet = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789-_';
$shortcode = '';
while($mediaid > 0){
$remainder = $mediaid % 64;
$mediaid = ($mediaid-$remainder) / 64;
$shortcode = $alphabet{$remainder} . $shortcode;
};
return $shortcode;
}
function shortcode_to_mediaid($shortcode){
$alphabet='ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789-_';
$mediaid = 0;
foreach(str_split($shortcode) as $letter) {
$mediaid = ($mediaid*64) + strpos($alphabet, $letter);
}
return $mediaid;
}

You can actually derive the MediaId from the last segment of the link algorithmically using a method I wrote about here: http://carrot.is/coding/instagram-ids. It works by mapping the URL segment by character codes & converting the id into a base 64 number.
For example, given the link you mentioned (http://instagram.com/p/Y7GF-5vftL), we get the last segment (Y7GF-5vftL) then we map it into character codes using the base64 url-safe alphabet (24:59:6:5:62:57:47:31:45:11_64). Next, we convert this base64 number into base10 (448979387270691659).
If you append your userId after an _ you get the full id in the form you specified, but since the MediaId is unique without the userId you can actually omit the userId from most requests.
Finally, I made a Node.js module called instagram-id-to-url-segment to automate this conversion:
convert = require('instagram-id-to-url-segment');
instagramIdToUrlSegment = convert.instagramIdToUrlSegment;
urlSegmentToInstagramId = convert.urlSegmentToInstagramId;
instagramIdToUrlSegment('448979387270691659'); // Y7GF-5vftL
urlSegmentToInstagramId('Y7GF-5vftL'); // 448979387270691659

Try the solution from this question: How can I get an direct Instagram link from a twitter entity?
You can get just the image by appending /media/ to the URL. Using your
You can even specify a size,
One of t (thumbnail), m (medium), l (large). Defaults to m.
So for a thumbnail: http://instagr.am/p/QC8hWKL_4K/media/?size=t

Your media ID is: 448979387270691659_45818965
This is how to get it.
- Go to instgram.com/username.
- Click the photo you want the id of.
- (Chrome instructions) right click on the photo (should be a popup image)
- Inspect element
- Search through the selected text, you should see something like this
photo448979387270691659_45818965
There should be your photo ID.
For some reason, this only seems to work with the popup, and not the actual image URL.

Here is python solution to do this without api call.
def media_id_to_code(media_id):
alphabet = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789-_'
short_code = ''
while media_id > 0:
remainder = media_id % 64
media_id = (media_id-remainder)/64
short_code = alphabet[remainder] + short_code
return short_code
def code_to_media_id(short_code):
alphabet = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789-_'
media_id = 0;
for letter in short_code:
media_id = (media_id*64) + alphabet.index(letter)
return media_id

In pure JS (provided your browser can handle XHRs, which every major browser [including IE > 6] can):
function igurlretrieve(url) {
var urldsrc = "http://api.instagram.com/oembed?url=" + url;
//fetch data from URL data source
var x = new XMLHttpRequest();
x.open('GET', urldsrc, true);
x.send();
//load resulting JSON data as JS object
var urldata = JSON.parse(x.responseText);
//reconstruct data as "instagram://" URL that can be opened in iOS app
var reconsturl = "instagram://media?id=" + urldata.media_id;
return reconsturl;
}
Provided this is your goal -- simply opening the page in the Instagram iOS app, which is exactly what this is about -- this should do, especially if you don't want to have to endure licensing fees.

If you add ?__a=1 at the end of Instagram public URLs, you get the data of the public URL in JSON.
For the media ID of an image from post URL, simply add the JSON request code at the post URL:
http://instagram.com/p/Y7GF-5vftL/?__a=1
The response will look like this below. You can easily recover the image ID from the "id" parameter in the reply...

You can use the shortcode media API from instagram. If you use php you can use the following code to get the shortcode from the image's URL:
$matches = [];
preg_match('/instagram\.com\/p\/([^\/]*)/i', $url, $matches);
if (count($matches) > 1) {
$shortcode = $matches[1];
}
Then send a request to the API using your access token (Replace ACCESS-TOKEN with your token)
$apiUrl = sprintf("https://api.instagram.com/v1/media/shortcode/%s?access_token=ACCESS-TOKEN", $shortcode);
回答11:
Same thing you can implement in Python-
import requests,json
def get_media_id(media_url):
url = 'https://api.instagram.com/oembed/?callback=&url=' + media_url
response = requests.get(url).json()
print(response['media_id'])
get_media_id('MEDIA_URL')

The iOS Instagram app has now registered for regular http links to open in the Instagram app and this deeplink methodology is no longer necessary.

For a period I had to extract the Media ID myself quite frequently, so I wrote my own script (very likely it's based on some of the examples here). Together with other small scripts I used frequently, I started to upload them on www.findinstaid.com for my own quick access.
I added the option to enter a username to get the media ID of the 12 most recent posts, or to enter a URL to get the media ID of a specific post.
If it's convenient, everyone can use the link (I don't have any adds or any other monetary interests in the website - I only have a referral link on the 'Audit' tab to www.auditninja.io which I do also own, but also on this site, there are no adds or monetary interests - just hobby projects).

Right click on a photo and open in a new tab/window. Right click on inspect element. Search for:
instagram://media?id=
This will give you:
instagram://media?id=############# /// the ID
The full id construct from
photoID_userID
To get the user id, search for:
instapp:owner_user_id Will be in content=
