我猜在你进入上传页面之前，你的信息会堆积起来。然后，它们将同时显示 将消息代码移动到base.html应该可以解决这个问题 编辑 如果您将消息放在内容块之前，则可以解决此问题

my base.html@YossiI know中没有消息代码。你应该把它从上传模板移到base.html。我已经将我上传的模板中的消息代码添加到base.html，并将其添加到base.html的内容部分，但现在没有消息显示，即使我进行了图像上传操作。如果不访问你的代码，很难说。我相信您可以覆盖上载模板中base.html的messages部分。因此不会显示任何消息。虽然在将消息代码添加到base.html的内容部分后，上载页面中没有消息，但现在在我的主页中显示了有关图像上载的每个操作的警报消息。我怀疑，之所以会发生这种情况，是因为我在base.html中添加了消息代码，事实上它在包括主页在内的每个页面中都进行了扩展@尤西
