因为每个请求都重定向到$route['admin/news/(:any)]
。例子:https://example.com/admin/news/edit/1.您必须更改路由顺序,如下所示$route['admin/news/delete/(:any)]='admin\u news/delete/$1'
$route['admin/news/edit/(:any)]='admin\u news/edit/$1'
$route['admin/news/create']='admin\u news/create'
$route['admin/news/(:any)]='admin\u news/view/$1'
$route['admin/news']='admin\u news/index'
我对4.0.4也有一些问题,我对此感到困惑。
在ci4中刚刚定义
myController extends BaseController
然后在路线上。php
$routes->get('/', 'myController::index');
查看更多https://codeigniter4.github.io/userguide/incoming/routing.html
这样说:
$route['admin/news/delete/(:any)'] = 'admin_news/delete/$1';
$route['admin/news/edit/(:any)'] = 'admin_news/edit/$1';
$route['admin/news/create'] = 'admin_news/create';
$route['admin/news/(:any)'] = 'admin_news/view/$1';
$route['admin/news'] = 'admin_news/index';
记得:
路由将按照定义的顺序运行。较高的路线总是优先于较低的路线。

在其核心,linkerd 的主要工作是路由:接受请求(HTTP,Thrift,Mux或其他协议),并将该请求发送到正确的目标。本指南将详细解释 linkerd 如何确定请求应该发送到哪里。这个过程由4个步骤组成:identification/识别,binding/绑定,resolution/解析和load balancing/负载均衡。 Linkerd 路由 识别 Identification/识
我的目标是让http://mydomain/route1呈现React组件Component1,让http://mydomain/route2呈现component2。因此,我认为编写如下路线是很自然的: http://mydomain/route1按预期工作,但http://mydomain/route2反而呈现Component1。 然后我读了这个问题,并将路线改为:
我已经稍微调整了React路由器的私有路由示例,以便与Redux玩得很好,但是当链接或重定向到其他页面时,不会呈现任何组件。这个例子可以在这里找到: https://reacttraining.com/react-router/web/example/auth-workflow 他们的PrivateRoute组件如下所示: 但是,因为我已经把它合并到一个Redux应用程序中,我不得不稍微调整一下私
我一直在致力于将我们的应用程序从React.js 0.13升级到15.4.2以及与之相关的依赖项。我可能很接近,但经过4天50个小时后,我终于到了终点,我最后的希望。 在升级过程中,react路由器被升级到4.0.0版,每个文档、教程和堆栈溢出问题都显示了如何编写路由器(所有这些都必须是正确的),但是,当我这样做时,它总是失败。要么说历史是必需的属性,要么当我通过示例添加它时,它仍然显示为未定义和
