golang xorm Chinese garbled code

When using golang's ORM tool xorm, we often encounter the problem of Chinese garbled characters, which brings a lot of trouble to our development and debugging. This article will introduce some methods to solve the problem of Chinese garbled characters.

1. Database character set setting

Before using xorm, you need to ensure that the character set of the database is set correctly. If the database's character set is set to utf8mb4, xorm will set the encoding to utf8 by default. This will lead to garbled Chinese characters or incomplete storage.

You can modify the database character set through the following sql statement:

ALTER DATABASE <database_name> CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

2. xorm field type setting

In xorm, you can specify the type of field. If the field type is set incorrectly, it will also cause Chinese garbled problems.

For example, if the type of a field is varchar(50), but the actual length that needs to be stored is greater than 50 characters, problems with Chinese garbled characters or truncation will occur.

When using xorm, you can set the field type through struct tag, for example:

type User struct {
    ID       int64  `xorm:"pk autoincr bigint(20)"`
    Username string `xorm:"varchar(50) notnull"`
    Password string `xorm:"varchar(255) notnull"`
}

3. xorm saves Chinese data

When using xorm saves Chinese When reading data, you need to ensure that the data is encoded correctly. If the string encoding method is GBK or GB2312, and the database encoding method is utf8, the Chinese data will be garbled.

xorm sets the encoding to utf8 by default. If you need to save GBK or GB2312 encoded data, you can solve it by setting the connection string:

engine, err := xorm.NewEngine("mysql", "user:password@tcp(host:port)/db?charset=gbk")

4. Use string escape

When using strings in SQL statements, you need to ensure that special characters in the string are escaped correctly. Otherwise, the SQL query will fail or produce unexpected results.

xorm uses ? placeholders instead of parameters, so manual escaping is not required. However, if you manually splice SQL statements, you need to use an escape function to ensure the correctness of the data:

escapedValue := mysql.EscapeString(originalValue)

The above are some methods to solve the problem of Chinese garbled characters in xorm, by correctly setting the character set, field type, character String encoding and escaping can avoid the problem of Chinese garbled characters in xorm and improve development efficiency and quality.
