Preface
According to user feedback, the open source project: go-gin-api 
Two small functions are related to language packs:
- Function 1: The error message returned by the interface supports both Chinese and English;
- Function 2: The error message of parameter verification supports both Chinese and English;
My implementation method is to select language when the project is installed, and then output the corresponding Chinese and English according to the selected language in the project, as shown in the figure below.
The error message returned by the interface supports both Chinese and English
Code location
Project code location: internal/pkg/code
How to use
// 与原来使用方式一致

If you want to add/edit error messages, just operate in the corresponding file.
The error message of parameter verification supports both Chinese and English
Code location
Project code location: internal/pkg/validation
How to use
req := new(createRequest)
if err := ctx.ShouldBindForm(req); err != nil {
fmt.Println(validation.Error(err))
}Error message language pack
The error message language pack uses go-playground/validator

Example

// 错误信息

// 错误信息
