英文:
Go failed to call JavaScript function because buffer was introduced into JavaScript code
问题
Go调用JavaScript函数失败，因为缓冲区被引入到JavaScript代码中。
secret.js
import Buffer from 'buffer';var Q = function(e) {return new Buffer("asdfl");};
main.go
func main() {jsFile := "./secret.js"bytes, err := ioutil.ReadFile(jsFile)if err != nil {panic(err)}vm := otto.New()_, err = vm.Run(string(bytes))if err != nil {panic(err)}enc, err := vm.Call("Q", nil, "123456")if err != nil {panic(err)}fmt.Println(enc.String())}
错误提示

otto只实现了Javascript ES5，而import是ES6的一个特性，所以你不能在你的JS代码中使用import。
更新：
你可以参考这篇帖子来实现自己的require方法。
英文:
otto only implemented Javascript ES5 while import is a feautre of ES6, so you couldn't use import in your JS code.
update:
You can follow this post to implement your own require method
