易优程序报错General error: 1366 Incorrect string value:
比如类似这样报错:
SQLSTATE[HY000]: General error: 1366 Incorrect string value: '\xF0\xA7\x92\xAD\xEF\xBC...' for column 'content' at row 1
请参考一下教程:
问题分析:
在mysql 5.5 之前,UTF-8编码只支持1-3个字节,支持BMP这部分的Unicode编码区;从MySQL 5.5开始,可以支持4个字节UTF编码 utf8mb4 ,一个字符能够支持更多的字符集,也能够支持更多表情符号。
utf8mb4兼容utf8,且比utf8能表示更多的字符,是utf8字符集的超集。所以现在一些新的业务,比如ISO等,会将MySQL数据库的字符集设置为utf8mb4。
解决方案:
1、将mysql版本升级为5.7版本
2、到数据库,把数据库字符集修改为:utf8mb4_general_ci
3、将数据表的 content 字段类型设置为:LONGTEXT、排序规则设置为:utf8mb4_general_ci
4、继续在MySQL数据库的my.cnf中关于字符集的配置修改为下面的配置了:
[client]
default-character-set=utf8mb4
[mysqld]
character-set-server = utf8mb4
collation-server = utf8mb4_unicode_ci
init_connect='SET NAMES utf8mb4'
skip-character-set-client-handshake = true
[mysql]
default-character-set = utf8mb4
宝塔中的配置文件路径(宝塔下安装的MySQL,my.cnf路径:根目录>etc):
也可以直接在宝塔MySQL 的配置文件中修改:
修改后,其内容为:
[client]
#password = your_password

default-character-set=utf8mb4 # 这是我们添加的

5、修改完之后,重载MySQL配置,并重启MySQL服务,即可存入输入法自带的表情了!
