Install redis-py and connect to Redis server settings and get Redis binary data

This document provides a brief introduction to using the Python version of Redis client redis-py to connect Redis and perform setup and acquisition of Redis binary data.

Description

Commands such as set,get,setnx,append can also be used to set binary data.

Because Redis's own client redis-cli is not easy to set up binary data, we use Python's client here to

There are three ways of installing redis-py:

1. Pip Install Redis

2. Easy_install Redis

3. Installing from Source: Python setup.py Install

Below we only introduce from the source installation redis-py.

Download Redis-py:

wget Https://github.com/andymccurdy/redis-py/archive/master.zip

>>> Import Redis

>>> R =redis. Strictredis (host= ' localhost ', port=6379, db=0)

>>>r.set (' mybits ', 0b10010010000)

True

>>> Bin (int (r.get (' mybits ')))

' 0b10010010000 '

>>> r.append (' mybits ', 0b1001)

5

>>> Bin (int (r.get (' mybits ')))

' 0b10110110101001 '

>>> r.get (' mybits ')

B ' 11689

We view the value of the Mybits key through REDIS-CLI:

[Email protected] ~]# redis-cli-h localhost-p 6379

localhost:6379> get ' mybits '

"11689"

You can see that the obtained binary (10110110101001) is converted to a decimal (11689) value.
