停止浏览器要求在刷新时重新发送表单数据 [英] Stop browsers asking to resend form data on refresh

问题描述

我通过 POST 提交了一个表单.我提交了表单，一切都很好，但是如果我尝试重新加载表单在提交后转到的新页面，我会收到您要重新发送数据吗"的提示.消息(火狐).它也可能发生在其他浏览器中，但我不确定.

I have a form submission via POST. I submit the form, and all is well, however if I try to reload the new page that the form goes to after submission, I get the "Do you want to resend data" message (Firefox). It might happen in other browsers too, but I'm not sure.

有没有办法阻止此消息弹出，以便我可以继续刷新页面?这对生产环境不利 - 用户可能会提交两次相同的表单！

Is there a way to stop this message popping up so I can go ahead and refresh the page? It's not good for production environments - users may submit the same form twice!

推荐答案

您需要使用 POST-Redirect-GET 模式.

You need to use the the POST-Redirect-GET pattern.

通过重定向到 GET 请求使您的表单响应.
这样，当用户刷新页面时，只会重新发送GET.

Make your form respond with a redirect to a GET request.
This way, when the user refreshes the page, it will only resend the GET.
