MySQL 存储 utf8mb4

b.设置库的字符集为UTF8mb4

2.如果是自己mysql服务器

 

[client]
 default-character-set = utf8mb4
 
[mysql]
 default-character-set = utf8mb4
 
[mysqld]
 character-set-client-handshake = FALSE
 character-set-server = utf8mb4
 collation-server = utf8mb4_unicode_ci
 init_connect=‘SET NAMES utf8mb4‘

 

3.修改数据表还有字段

ALTER TABLE `user` MODIFY COLUMN nickname VARCHAR(64) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;
ALTER TABLE `user` CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci; 

4.修改库连接

‘charset‘   => ‘utf8mb4‘,
