Instagram 粉丝数量按 `username` 返回一个账号的粉丝数 `follower_count` 和关注数 `following_count`，附带用户 ID、用户名、显示名、头像和主页链接，不返回名单。它回答「这个账号有多少粉丝」，适合大批量核对达人粉丝量、定时记录账号增长，或者在拉取粉丝名单前先估一下规模。

只要数字时用它最省事；要逐个看粉丝是谁，用粉丝列表；要看这个账号关注了谁，用关注列表。

## FAQ

### 粉丝数量和粉丝列表怎么选？

只需要数字，比如筛选达人或记录增长，用粉丝数量，它返回一个对象；要知道粉丝具体是谁、做受众分析，用粉丝列表，它逐个返回账号。先看数量再决定要不要拉名单，能省不少调用。

### 怎么用它记录粉丝增长？

每天固定时间读一次，把 `follower_count` 和读取时间一起存下来，前后相减就是日增量。同时存下 `id`，方便和别的能力返回的记录对上。

### 和主页详情里的粉丝数一样吗？

两处都是账号的粉丝数。主页详情还返回简介、帖子数、外链、最近帖子等一整套资料；只关心 `follower_count` 和 `following_count` 时，粉丝数量返回的内容更少、更好处理。
