文件上传

第一步：html写UI

    <div style="padding-top:20px;">
        <form enctype="multipart/form-data" class="navbar-form" action="/qm/xradar/upload_data/" method="post">
            <div class="form-group">
                <input type="file" class="form-control" name="myfile"/>
            </div>
            <div class="form-group">
                <input type="submit" class="layui-btn" value="上传"/>
            </div>
            {% csrf_token %}
        </form>
    </div>

加入提示信息

    <script>
        $(function () {
            Uploadfile();
        });

        //判断上传文件是否为空
        function Uploadfile() {
            var upload_msg;
            upload_msg = "{{ upload_msg }}";
            if (upload_msg == 2) {
                alert("上传成功！");
            }
            if (upload_msg == 1) {
                alert("请选择上传文件！");
            }
            if (upload_msg == 3) {
                alert("文件上传失败！");
            }
        }
    </script>

第二步：qmviews.py文件编写视图函数

@login_Check
def upload_data(request):
    if request.method == "POST":  # 请求方法为POST时，进行处理
        myFile = request.FILES.get("myfile", None)  # 获取上传的文件，如果没有文件，则默认为None
        if not myFile:
            upload_msg = 1
        else:
            try:
                cur_path = os.path.abspath('...')
                CUR_PATH = cur_path + '\\upload\\qm\\'

                destination = open(os.path.join(CUR_PATH, myFile.name), 'wb+')  # 打开特定的文件进行二进制的写操作
                for chunk in myFile.chunks():  # 分块写入文件
                    destination.write(chunk)
                destination.close()
                upload_msg = 2
                writeLog_info('[文件%s]，上传成功！' % (myFile.name))
            except Exception as e:
                upload_msg = 3
                writeLog_error('[文件%s]，上传失败：%s' % (myFile.name,e))
    return render(request, "../templates/qm/xradar.html", {"upload_msg": upload_msg})

第三步：urls.文件添加路由

    url('^xradar/upload_data/$', qmviews.upload_data),
