It does this because browsers don't support PUT/DELETEvery well. You can read more about this in the Rails Guides:
这样做是因为浏览器不支持PUT/DELETE很好。您可以在Rails 指南中阅读更多相关信息：
However, most browsers don't supportmethods other than “GET” and “POST” when it comes to submitting forms.
Rails works around this issue by emulating other methods over POST with a hidden input named
"_method", which is set to reflect the desired method.
但是，大多数浏览器在提交表单时不支持“GET”和“POST”以外的方法。
Rails 通过使用名为 的隐藏输入模拟 POST 上的其他方法来解决此问题
"_method"，该输入设置为反映所需的方法。
