Laravel 在创建函数时找不到页面

Question

最近我开始使用 Laravel 作为框架进行编程。一切顺利，但我尝试在运行时使用以下消息编写创建脚本：

Sorry, the page you are looking for could not be found.

那是在创建表单中发布接受后，我已经成功创建了索引、显示、更新和删除功能。所以到我的控制器的路由是正确的，文件存在......我完全卡住了，看不出有什么不正确的。

请帮忙。

我没有重定向 public 文件夹，所以我仍在使用完整路径，在其他模块 (/gymmgr/public/lockers) 上没有问题。

我把代码发给你：

Answer 1

您的创建表单有：

<form method="post" action="{{ route('lockers.create') }}">
...
<input type="hidden" name="_method" value="put">

所以您正在向您的创建路线发送 PUT 请求。 As the docs describe，resource 声明设置的 .create 路由期待 GET（检查它设置的 table 操作）。因此该请求将失败并显示 404，因为没有设置匹配的路由。

此外，create 路由虽然命名容易混淆，但用于显示创建表单，不保存您在该表单中输入的数据。所以你不应该向你的创建路线提交数据。

您需要：

更改您的表单操作以指向您的 store 路线：... action="{{ route('lockers.store') }}
删除表单方法欺骗，store 期望 POST 这是默认情况下没有任何欺骗的情况。
