Root Cause

缓存键包含空格或特殊字符，memcached不支持

generic

中文

Django缓存键中使用了空格等非法字符，导致后端缓存服务拒绝

Workarounds

  1. 95% success 
    from django.core.cache import make_key; safe_key = make_key('my key with spaces')
  2. 90% success 
    key = key.replace(' ', '_')

Dead Ends

Common approaches that don't work:

  1. 90% fail

    缓存操作会失败，无法存取数据

  2. 50% fail

    长度不是问题，非法字符才是
