Some thoughts about "Building a sliding window rate limiter with Redis"

Reading Building a sliding window rate limiter with Redis, and w/o addressing the actual logic (which may or may not work).

Optimize by:

  1. Lua seems a much better choice: idiompotent, portable, server-side, less bandwidth, atomic...
  2. The call to ZRANGEBYSCORE seems to be unused, should be commented out if so
  3. Looking at the use of ZRANGE, it appears that ZCARD it what's actually needed

The (untested) Lua snippet:

git.io custom URL

Update: As of 11 January 2022, git.io no longer accepts new URLs.

Command:

curl https://git.io/ -i -F "url=https://github.com/YOUR_GITHUB_URL" -F "code=YOUR_CUSTOM_NAME"

URLs that can be created is from:

  • https://github.com/*
  • https://*.github.com

用JS计算字符所占字节数
/**
 * 计算字符串所占的内存字节数,默认使用UTF-8的编码方式计算,也可制定为UTF-16
