vue问题三：element ui的upload组件上传图片成功和移除事件

element ui的upload组件上传图片成功和移除事件：

登录后获取到后台传的token存到中：

sessionStorage.setItem("token",data.obj.token);

用getItem取出：

sessionStorage.getItem('token')

          upload
            ref="upload"
            class="wid"
            :action="upimg"
            list-type="picture"
            :on-preview="handlePictureCardPreview"
            :on-remove="handleRemove"
            :on-error="errorimg"
            :on-success="handleSuccess"
            :headers="headers"
            :before-upload="brforeimg"
            :limit="1"
            :on-exceed="exceed"
          >
            添加图片
