将我的go函数输出公开给Qml

Question

我有一个函数，它在我的go文件中给我一个gdb backtrace，如：

func backtrace(){... fmt.Println ("backtrace details")}

我希望将此函数输出公开给qml。我怎么能这样做？

编辑：

func backtrace(){
    output,_:=debug.Send("stack-list-frames")
    pay:=output["payload"]

    payAssert:=pay.(map[string]interface{})

    stack:=payAssert["stack"]

    stackAssert:=stack.([]interface{})
    nbreFct:=len(stackAssert)
    for i:=0; i<=nbreFct-1 ; i++{
        stackSepare:=stackAssert[i]
        stackSepareAssert:=stackSepare.(map[string]interface{})

        frame:=stackSepareAssert["frame"]
        frameAssert:=frame.(map[string]interface{})

        index := strconv.Itoa(i)
        fmt.Println("Frame : ", index)

        //list variables by frame
        output_variables,_  := debug.Send("stack-list-variables","--thread","1","--frame",index,"--simple-values")
        map_variables := output_variables["payload"]
        m_variables := map_variables.(map[string]interface{})
        variables := m_variables["variables"]
        fmt.Println("Variables : ", variables)

        fun:=frameAssert["func"]
        line:=frameAssert["line"]
        level:=frameAssert["level"]

        fmt.Println("level : ",level,"function : ",fun ,"  line : ",line)
    }
}

如何改进代码输出以将输出公开给qml？
