Go
Structure
The file package must be inner and export a function called main:
go
package inner
func main(param1 string, param2 int) (map[string]interface{}, error) {
return map[string]interface{}{
"result": param1,
"count": param2,
}, nil
}
Important:
- •Package must be
inner - •Return type must be
({return_type}, error) - •Function name is
main(lowercase)
Return Types
The return type can be any Go type that can be serialized to JSON:
go
package inner
type Result struct {
Name string `json:"name"`
Count int `json:"count"`
}
func main(name string, count int) (Result, error) {
return Result{
Name: name,
Count: count,
}, nil
}
Error Handling
Return errors as the second return value:
go
package inner
import "errors"
func main(value int) (string, error) {
if value < 0 {
return "", errors.New("value must be positive")
}
return "success", nil
}
