"""

修复 docker-compose.yml 中 REDIS_URL 默认值的 URL-encode 问题。
|
||
|
|
|
||
|
|
背景:
|
||
|
|
- 2026-06-15 故障:REDIS_URL 里的密码 R3d!s@2026#Secure 含 @ # 两个 URL 保留字符,
|
||
|
|
Python redis 库解析时密码被截断成 R3d!s,导致鉴权失败 → Redis 连接超时
|
||
|
|
- 修复:把密码 URL-encode(@→%40, #→%23, !→%21)
|
||
|
|
- ⚠️ 关键: 只 URL-encode REDIS_URL 那行的密码,redis-server --requirepass
|
||
|
|
和 healthcheck 的 redis-cli -a 都必须保持**明文**(否则 Redis 容器启动失败/鉴权失败)
|
||
|
|
|
||
|
|
用法:
|
||
|
|
sudo python3 /tmp/patch-redis-url.py
