如何在GoDuktape中停止执行js函数

如何在GoDuktape中停止执行js函数,go,duktape,Go,Duktape,我有以下go duktape代码: package main import ( "fmt" "gopkg.in/olebedev/go-duktape.v3" "time" ) func main() { code := "function test(){log('testing');log('testing2');done();done();};" resp := make(chan string) ctx := duktape.New()

我有以下go duktape代码:

package main

import (
    "fmt"
    "gopkg.in/olebedev/go-duktape.v3"
    "time"
)

func main() {
    code := "function test(){log('testing');log('testing2');done();done();};"
    resp := make(chan string)
    ctx := duktape.New()            
    go doExec(code, ctx, resp)
    select {
    case r := <-resp:
        fmt.Printf("%s\n", r)
    case <-time.After(5 * time.Second):
        fmt.Printf("Execution timeout\n")
    }
    kill(ctx)
    close(resp)

}

func kill(ctx *duktape.Context) {
    ctx.DestroyHeap()
    ctx.Destroy()
}

func doExec(code string, ctx *duktape.Context, resp chan string) {
    ctx.PushGlobalGoFunction("done", func(c *duktape.Context) int {
        resp <- "We're done!!"
        return 0
    })
    ctx.PushGlobalGoFunction("log", func(c *duktape.Context) int {
        fmt.Println(c.SafeToString(-1))
        return 0
    })
    err := ctx.PevalString(code + ";try{test()}catch(e){log('Error in execution');}")
    if err != nil {
        fmt.Printf("Error is %s\n", err.Error())
        resp <- "Error in exec"
    }
}
主程序包
进口(
“fmt”
“gopkg.in/olebedev/go duktape.v3”
“时间”
)
func main(){
代码:=“函数测试(){log('testing');log('testing2');完成();完成();};”
resp:=制造(成串)
ctx:=duktape.New()
go doExec(代码、ctx、resp)
挑选{

案例r:=在关闭频道之前,你能在
done()
内部调用
kill()
吗?@svsd我试过了,但是我得到了segfaults。如果我在
done()
内部调用
kill()
,它会破坏duktape堆和上下文,而
PevalString()
仍在执行,因为它仍必须执行第二个
done()
调用
