go.mod:
require github.com/dop251/goja v0.0.0-20230919151941-fc55792775de
Run Code:
package main
import (
"fmt"
"log"
"github.com/dop251/goja"
)
func main() {
if err := run(); err != nil {
log.Println("failed:", err)
}
}
const script = `
function test(obj) {
// return obj.MarshalJSON();
return JSON.stringify(obj);
}
`
type PermissionType int
const (
_ PermissionType = iota
PermissionTypeList = 1
)
func (t PermissionType) MarshalJSON() ([]byte, error) {
switch t {
case PermissionTypeList:
return []byte(`1`), nil
}
return nil, fmt.Errorf("invalid permission_type: %v", t)
}
func run() error {
runtime := goja.New()
_, err := runtime.RunString(script)
if err != nil {
return fmt.Errorf("run string: %w", err)
}
var fn func(obj interface{}) (interface{}, error)
if err := runtime.ExportTo(runtime.Get("test"), &fn); err != nil {
return fmt.Errorf("export: %w", err)
}
if fn == nil {
return fmt.Errorf("export function is nil")
}
t := PermissionType(10)
result, err := fn(t)
if err != nil {
return fmt.Errorf("exec: %w", err)
}
log.Println("result: ", result)
return nil
}
It will panic with message:
go run main.go
panic: invalid permission_type: 10 [recovered]
panic: invalid permission_type: 10 [recovered]
panic: invalid permission_type: 10 [recovered]
panic: invalid permission_type: 10
