红色不可再等Redis邮箱注册快速体验（redis邮箱注册）
Recently, with the rapid development of Internet technology, web applications have been developing rapidly, and registration by mlbox is a common login method. During this period, there are many suggestions that have to store user registration data to a database. Redis, an open source BSD license, is a high-performance key-value distributed memory alarm system. In this paper, we will use the features given by Redis to demonstrate the mlbox registration process.
Redis provides a key-value storage type. Users can store data in the form of key-value prs. In the mlbox registration process, we need to save the registered user data. We can use a hash type to store them. In the hash type, users can be stored in the form of fields and values. We create a string type key to save user data.
For example, the following script creates a Redis hash field for the user with the key name eml_number. In the field, store user data such as name, profession, and telephone number. In the field value, use a JSON string to store the user data.
`
127.0.0.1:6379> hset eml_number name “Tom”
(integer) 1
127.0.0.1:6379> hset eml_number profession “doctor”
(integer) 1
127.0.0.1:6379> hset eml_number telephone 123456
(integer) 1
`
In this way, the user data is stored in the key-value pr of Redis. With the help of Redis, the user storage process is simple and efficient, and the cost of the storage space used is greatly reduced.
Next we need to check whether the mlbox has been registered. Redis provides a set type, which stores only unique values. We can store a user’s mlbox address in a set, which can represent if the user has registered or not.
For example, the following script stores user mlbox in a Redis set.
`
127.0.0.1:6379> sadd eml_set tom@test.com
(integer) 1
`
With the help of the set type in Redis, we can detect quickly whether the mlbox is already registered. It is more efficient than comparing data with the database in traditional applications.
Finally, when the user successfully registers, we need to delete the data private. How to delete the data stored in Redis? Redis provides the Delete command, which deletes keys in Redis. For example, if we want to delete the key eml_number we created above, we can use the following script:
`
127.0.0.1:6379> del eml_number
(integer) 1
`
By using Redis, this entire process can be carried out quickly and efficiently. In addition, its easy operation, high performance and low cost make it ideal for web applications. With the help of Redis, user registration is no longer a problem. Redis is an amazing data storage technology that deserves more attention.
