busboy.on('field', function(fieldname, val) { req.body[fieldname] = val; });绘制2px行而不是1px。如果您截取下面的JSfiddle输出，您将看到该行高2px。

如何绘制1px线？

Answer 1

您在两行像素之间绘制的线条，因此它将其两侧着色为灰色而不是黑色。将您的代码更改为

MariaDB [bb]> insert into table (val) VALUES(99);
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'table (val) VALUES(99)' at line 1

MariaDB [bb]> insert into `table` (val) VALUES(99);
Query OK, 1 row affected (0.00 sec)

MariaDB [bb]>

只能画一行像素。

无法绘制1px线
