折腾:

【已解决】PySpider中保存数据到mysql

期间,需要设置charset是utf-8,但是不知道设置参数值是utf-8还是utf8

mysql charset

MySQL :: MySQL 5.7 Reference Manual :: 10.5 Configuring Application Character Set and Collation

好像是utf8

MySQL :: MySQL 5.5 Reference Manual :: 10.10 Supported Character Sets and Collations

<code>| utf8 | UTF-8 Unicode | utf8_general_ci | 3 |
</code>

自己去看看:

<code>mysql&gt; show CHARACTER SET;

再见乱码:5分钟读懂MySQL字符集设置 – 程序猿小卡 – 博客园

<code>mysql&gt; SHOW VARIABLES LIKE "character_set_server";
+----------------------+--------+
| Variable_name        | Value  |
+----------------------+--------+
| character_set_server | latin1 |
+----------------------+--------+
1 row in set (0.08 sec)

mysql&gt; SHOW VARIABLES LIKE "collation_server";
+------------------+-------------------+
| Variable_name    | Value             |
+------------------+-------------------+
| collation_server | latin1_swedish_ci |
+------------------+-------------------+
1 row in set (0.01 sec)

mysql&gt;
</code>

【总结】

所以此处charset设置为utf8即可。

更多其他字符编码方面的设置和参数,等遇到了再说。
