python - Redis 示例给出 HTTP 400 : Bad request error

Question

我正在尝试在我的 Cherrypy 服务器中缓存 MySQL 查询。

我在安装pylibmc时一直想不出如何解决这个错误，所以我决定使用Redis-py。

我在这里尝试一个非常简单的例子。

import redis
cache = redis.StrictRedis(host='localhost', port=8080, db=0)
       ...
       ...
cache.set('0', '1') # I also tested with other string keys, but failed with same error

它抛出以下错误!

[05/May/2014:13:11:13] HTTP Traceback (most recent call last):
  File "/Library/Python/2.7/site-packages/cherrypy/_cprequest.py", line 656, in respond

    return self.parse_response(connection, command_name, **options)

    response = connection.read_response()
  File "/Library/Python/2.7/site-packages/redis/connection.py", line 339, in read_response
    response = self._parser.read_response()

    (str(byte), str(response)))

我不知道出了什么问题，当我不使用 Redis 时，我的网站在 8080 端口的本地主机上运行没有问题。

您的网络服务器在端口 8080 上运行，而不是您的 Redis 服务器。您的 Redis 服务器很可能在端口 6379 上运行，除非您出于某种原因更改了配置。现在您正在尝试对您的网络服务器运行 Redis 查询，但这是行不通的。请确保您连接到正确的 Redis 服务器地址和端口，然后重试。
