海外TECH	DEV Community	A Complete Guide to Redis Hashes	https://dev.to/smpnjn/a-complete-guide-to-redis-hashes-41m3	A Complete Guide to Redis HashesRedis hashes are a type of record stored in a Redis database They are a little like JSON objects and store data as key value pairs They are mutable so can be easily changed and updated depending on your needs As such they are a great way to store certain typeso f data in Redis If you are new to Redis make sure you install it first before trying this tutorial Redis hashes are flat in structure so we can t have multiple levels like we do in JSON If we want to add a new hash we use the terminal command HSET Start redis by running redis cli in terminal and then try running the following to set a new key HSET user keyOne valueOne keyTwo valueTwoThe naming convention of a redis hash is typed as hash key so here we have user to represent user number The syntax above may seem confusing but it follows this convention HSET hash key key value key value key value So when we wrote HSET user keyOne valueOne keyTwo valueTwo we created a new hash called user and then we created a key called keyOne with a value valueOne and a key called keyTwo with a value of valueTwo You can continue this pattern forever meaning your hash can have as many key value pairs as you like Updating and Adding New Keys in Redis HashesWe can use the HSET command to create a hash and also update or add to it For example to add a new key and value to user we simply run HSET again with the new key and value HSET user keyThree valueThreeIf we later want to update keyThree to have a value of valueFour we would run HSET again to overwrite the value of keyThree HSET user keyThree valueFour Getting Hash Key Values and Hashes in RedisIf you want to get all keys and values in a specific hash you use HGETALL This will return all keys and values within the hash specified For example HGETALL user Will return keyOne valueOne keyTwo valueTwo Meanwhile if you want to get the value of one specific key within a hash we use HGET For example to get the value of keyOne we run HGET user keyOneWhich will return valueOne Increasing Hash Key Values by an amountA common use case for hashes is storing user scores on a scoreboard In this case it s pretty common that we d want to increase the user s score by a certain amount if it is a number For example suppose we have this scoreboard HSET scoreboard userNameOne If we need to update the user s score we can easily increase the user s score by a certain amount using HINCRBY Let s say we want to increase the user s score by Instead of using HSET we could do this HINCRBY scoreboard userNameOne Deleting Hash Keys and Values in RedisFinally if you want to delete hash keys for a specific hash we use HDEL Taking our first example of user if we wanted to delete keyOne we could do so by running the following command HDEL user keyOneIf you didn t want to have the hash at all and wanted to remove user entirely then you can simply use del instead del user	2022-10-01 16:49:33
