  • django 视图函数返回queryset对象或日期对象至浏览器ajax接收的写法

    class MyDateTimeEncode(json.JSONEncoder):
        def default(self, o):
            if isinstance(o, datetime):
                return o.strftime('%Y-%m-%d %H:%M:%S')
            elif isinstance(o, date):
                return o.strftime('%Y-%m-%d')
            else:
                return json.JSONEncoder.default(self, o)
    
    def seriallizer_view(request):
        books_obj = models.Book.objects.all()
        # 传queryset对象
        # json_books_obj = serializers.serialize('json', books_obj)
        time1 = datetime.now()
        json_time1 = json.dumps(time1, cls=MyDateTimeEncode)
        if request.method == "POST":
            return HttpResponse(json_time1)
            # return JsonResponse({"key": 'OK'})  # 默认只能传值字典,其余字符串等需要设置参数safe=False
        return render(request, 'serial.html')

    前端ajax代码:

    <!DOCTYPE html>
    <html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>Title</title>
        <script src="https://cdn.bootcss.com/vue/2.5.17-beta.0/vue.js"></script>
        <script src="https://cdn.bootcss.com/vue-router/3.0.1/vue-router.js"></script>
        <script src="https://cdn.bootcss.com/jquery/3.3.1/jquery.js"></script>
        <script src="https://cdn.bootcss.com/jquery-cookie/1.4.1/jquery.cookie.js"></script>
    </head>
    <body>
    <button id="btn">点我获取数据</button>
    
    <script>
        $("#btn").click(function () {
            {#$.ajax({#}
            {#    url:"",#}
            {#    type:'post',#}
            {#    contentType:'json',#}
            {#    headers:{"X-CSRFToken":$.cookie("csrftoken")},#}
            {#    data:{},#}
            {#    success:function (res) {#}
            {#        data = JSON.parse(res);#}
            {#        console.log(data[0]);#}
            {#        console.log(typeof res);#}
            {#        for(var i=0;i<data.length;i++)#}
            {#        $("body").append(`<li>${data[i].fields.title}</li>`)#}
            {#    }#}
            {#)#}
            $.ajax({
                url:"",
                type:'post',
                contentType:'json',
                headers:{"X-CSRFToken":$.cookie("csrftoken")},
                data:{},
                success:function (res) {
                  console.log(res);
                  console.log(typeof JSON.parse(res))
                }
            })
        })
        
    </script>
    </body>
    </html>
