今天對clubot進行了升級, 但是導入數據后中文亂碼, 一開是找資料說是在創建引擎的時候添加編碼信息:
engine = create_engine("mysql://root:@localhost:3306/clubot?charset=utf8")但是這并不行, 然后查看表信息:
> show create table clubot_members;clubot_members | CREATE TABLE `clubot_members` ( `id` int(11) NOT NULL AUTO_INCREMENT, `email` varchar(100) DEFAULT NULL, `nick` varchar(50) DEFAULT NULL, `last_say` timestamp NULL DEFAULT NULL, `last_change` timestamp NULL DEFAULT NULL, `isonline` int(11) DEFAULT NULL, `join_date` timestamp NULL DEFAULT NULL, PRIMARY KEY (`id`), UNIQUE KEY `email` (`email`), UNIQUE KEY `nick` (`nick`)) ENGINE=InnoDB AUTO_INCREMENT=20 DEFAULT CHARSET=latin1;
發現原來創建表的時候用的latin1編碼, 而老的表是用utf-8編碼創建的, SQLAlchemy中并沒有發現有創建表時指定指定編碼的方法. 所以只能在MySQL本身來找:
> show VARIABLES like "character%%";+--------------------------+-----------------------------+| Variable_name | Value |+--------------------------+-----------------------------+| character_set_client | utf8 || character_set_connection | utf8 || character_set_database | latin1 || character_set_filesystem | binary || character_set_results | utf8 || character_set_server | latin1 || character_set_system | utf8 || character_sets_dir | /data/share/mysql/charsets/ |+--------------------------+-----------------------------+8 rows in set (0.00 sec)> show create database clubot;+----------+-------------------------------------------------------------------+| Database | Create Database |+----------+-------------------------------------------------------------------+| clubot | CREATE DATABASE `clubot` /*!40100 DEFAULT CHARACTER SET latin1 */ |+----------+-------------------------------------------------------------------+1 row in set (0.00 sec)
發現 MySQL默認的和數據庫都是latin1的編碼, 所以更改數據庫配置
分別在[client] [mysqld]下添加
這時重啟MySQL居然起不來, 說default-character-set是無效的變量, 查看MySQL版本發現是5.5, 找資料說5.5的服務端編碼設置變量是character-set-server, 所以將[mysqld]上的default-character-set = utf8改為 character-set-server = utf8, 并重啟MySQL
然后更改數據庫編碼:
刪除新建的表, 并重新導入數據中文就正常了
