如何在Golang中将json数据提供给页面？

Question

It's not a matter of marshal or unmarshal, it's what do I need to write to my writer in combination with my Jquery?

Right now I have this for Go

func serveJson(w http.ResponseWriter, r *http.Request, ps httprouter.Params){
    j, _ := os.Open("adjs.json")

    defer j.Close()

    var obj respWords

    json.NewDecoder(j).Decode(&obj)
    js, _ := json.Marshal(obj)

    w.Header().Set("Content-Type", "application/json")

    w.Write(js)
}

and this is my jquery getting the json

<script type = "text/javascript">
    function randomize() {
        scene = {}
        $.getJSON('adjs.json', function(scene){
           console.log('encoding')
        })
        console.log(scene)
    }
</script>

Answer 1

your async request does not save the data to the external variable, do your logic in the success function of your ajax request

$.getJSON('adjs.json', function(scene){
           console.log(scene);
           //do logic here with scene
        });
