Instagram API - 如何检索用户在 Instagram 上关注的人员列表

我想知道如何检索用户在 Instagram 上关注的人员列表。假设这个特定用户是我关注的人。所以我可以在 Instagram 应用程序上访问他/她的照片和他的关注者。

如何使用 Instagram API 来执行此操作？这样做合法吗？

1. 在浏览器上打开 Instagram；
2. 登录 Instagram；
3. Open your browser's console (CTRL + SHIFT + J);
4. 粘贴下面的代码；
5. 更新第一行的用户名；
6. RUN IT (Hit Enter)

const username = "USER_NAME_HERE";

/**
 * Initialized like this so we can still run it from browsers, but also use typescript on a code editor for intellisense.
 */
let followers = [{ username: "", full_name: "" }];
let followings = [{ username: "", full_name: "" }];
let dontFollowMeBack = [{ username: "", full_name: "" }];
let iDontFollowBack = [{ username: "", full_name: "" }];

followers = [];
followings = [];
dontFollowMeBack = [];
iDontFollowBack = [];
