通过ID查找Instagram媒体网址 [英] Find Instagram media url by ID

问题描述

由于不是非常正式的HTTP调用，我发现了媒体ID，图像URL和Instagram帖子的用户名.

Thanks to a HTTP call not very official, I find media ID, image URL, and user name of Instagram posts.

但是我需要Instagram上每条帖子的URL，而且我不知道如何找到它.

But I need the URL of each post on Instagram, and I don't know how to find it.

是否存在像instagram.com/something/{mediaID}这样的URL重定向到instagram.com/p/{mediaSlug}，还是通过媒体ID查找的另一种方法(当然不使用官方API！)?

Is there an URL like instagram.com/something/{mediaID} which redirect to instagram.com/p/{mediaSlug}, or another method to find slug by media ID (without using the official API of course!) ?

例如，我有:

唯一编号:1238578393243739039028_1408429375

Unique number : 1238578393243739028_1408429375

媒体ID:1238578393243739028

Media ID : 1238578393243739028

用户ID:1408429375

User ID : 1408429375

推荐答案

Java解决方案:

public static String getInstagramPostId(String mediaId) {
    String postId = "";
    try {
        long id = Long.parseLong(mediaId.substring(0, mediaId.indexOf('_')));
        String alphabet = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789-_";

        while (id > 0) {
            long remainder = (id % 64);
            id = (id - remainder) / 64;
            postId = alphabet.charAt((int)remainder) + postId;
        }
    } catch (Exception e) {
        e.printStackTrace();
    }

    return postId;
}
