Many functions of "apifm" support extended attribute settings, such as publishing articles, publishing products, editing user information, etc.
For example, when editing user information, we hope to be able to set the five extended attributes of the user's registration channel, school, major, age, and hobbies. How can we avoid having to create these five extended attributes every time we edit?
By setting parameters in the system parameters, the above five extended fields are automatically created when editing user information, as shown below:

Through different parameter settings, different default extended attributes can be achieved:
#User default extended attributes
Parameter name:
> user.ext.fileds
>
Parameter value:
> Registration channel, school, major, age, hobbies
>
_The above five extended attributes can be separated by English commas; if there are more extended attributes, so on_
# Product default extended attributes
Parameter name:
> goods.ext.fileds
>
Parameter value:
> Certificate number, 3C product model, voltage, power supply mode
>
_When you add a product in the future, you will be prompted by default to fill in the product's certificate number, 3C product model, voltage, and power mode._
