来来改造test视图文件
<span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(0, 0, 0)">@section</span>(<span style="box-sizing: border-box;color: rgb(170, 17, 17)">'content'</span>)</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"> <span style="box-sizing: border-box;color: rgb(152, 26, 26)"><</span><span style="box-sizing: border-box;color: rgb(0, 0, 0)">form</span> <span style="box-sizing: border-box;color: rgb(0, 0, 0)">action</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">=</span><span style="box-sizing: border-box;color: rgb(170, 17, 17)">"/demo/store"</span> <span style="box-sizing: border-box;color: rgb(0, 0, 0)">method</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">=</span><span style="box-sizing: border-box;color: rgb(170, 17, 17)">"POST"</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">></span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"> <span style="box-sizing: border-box;color: rgb(0, 0, 0)">@csrf</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"> <span style="box-sizing: border-box;color: rgb(0, 0, 0)">用户名：</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)"><</span><span style="box-sizing: border-box;color: rgb(0, 0, 0)">input</span> <span style="box-sizing: border-box;color: rgb(0, 0, 0)">type</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">=</span><span style="box-sizing: border-box;color: rgb(170, 17, 17)">"text"</span> <span style="box-sizing: border-box;color: rgb(0, 0, 0)">name</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">=</span><span style="box-sizing: border-box;color: rgb(170, 17, 17)">"username"</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">></span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"> <span style="box-sizing: border-box;color: rgb(152, 26, 26)"><</span><span style="box-sizing: border-box;color: rgb(0, 0, 0)">input</span> <span style="box-sizing: border-box;color: rgb(0, 0, 0)">type</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">=</span><span style="box-sizing: border-box;color: rgb(170, 17, 17)">"submit"</span> <span style="box-sizing: border-box;color: rgb(0, 0, 0)">name</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">=</span><span style="box-sizing: border-box;color: rgb(170, 17, 17)">"提交"</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">></span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"> <span style="box-sizing: border-box;color: rgb(152, 26, 26)"></</span><span style="box-sizing: border-box;color: rgb(0, 0, 0)">form</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">></span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(0, 0, 0)">@endsection</span></span>
注意到没有，action中提交地址的写法，至今，很多开发环境中仍旧是这样写。这样写当然不会有什么问题。
准备工作：
为路由加上路由名称
<span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(0, 0, 0)">Route</span>::<span style="box-sizing: border-box;color: rgb(0, 0, 0)">get</span>(<span style="box-sizing: border-box;color: rgb(170, 17, 17)">'demo'</span>, <span style="box-sizing: border-box;color: rgb(170, 17, 17)">'DemoController@index'</span>)<span style="box-sizing: border-box;color: rgb(152, 26, 26)">-></span><span style="box-sizing: border-box;color: rgb(0, 0, 0)">name</span>(<span style="box-sizing: border-box;color: rgb(170, 17, 17)">'demo'</span>);</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(0, 0, 0)">Route</span>::<span style="box-sizing: border-box;color: rgb(0, 0, 0)">get</span>(<span style="box-sizing: border-box;color: rgb(170, 17, 17)">'demo/test'</span>, <span style="box-sizing: border-box;color: rgb(170, 17, 17)">'DemoController@test'</span>)<span style="box-sizing: border-box;color: rgb(152, 26, 26)">-></span><span style="box-sizing: border-box;color: rgb(0, 0, 0)">name</span>(<span style="box-sizing: border-box;color: rgb(170, 17, 17)">'demo.test'</span>);</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(170, 85, 0)">// 新增</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(0, 0, 0)">Route</span>::<span style="box-sizing: border-box;color: rgb(0, 0, 0)">post</span>(<span style="box-sizing: border-box;color: rgb(170, 17, 17)">'demo/store'</span>,<span style="box-sizing: border-box;color: rgb(170, 17, 17)">'DemoController@store'</span>)<span style="box-sizing: border-box;color: rgb(152, 26, 26)">-></span><span style="box-sizing: border-box;color: rgb(0, 0, 0)">name</span>(<span style="box-sizing: border-box;color: rgb(170, 17, 17)">'demo.store'</span>);</span>
控制器添加方法
<span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(170, 85, 0)">// DemoController.php</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box"></span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(119, 0, 136)">public</span> <span style="box-sizing: border-box;color: rgb(119, 0, 136)">function</span> <span style="box-sizing: border-box;color: rgb(0, 0, 255)">store</span>(<span style="box-sizing: border-box;color: rgb(0, 0, 0)">Request</span> <span style="box-sizing: border-box;color: rgb(0, 85, 170)">$request</span>)</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">{</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"> <span style="box-sizing: border-box;color: rgb(0, 0, 0)">dd</span>(<span style="box-sizing: border-box;color: rgb(0, 85, 170)">$request</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">-></span><span style="box-sizing: border-box;color: rgb(0, 0, 0)">all</span>());</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">}</span>
视图文件中URL写法
方式一：route函数【主推荐】
<span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(152, 26, 26)"><</span><span style="box-sizing: border-box;color: rgb(0, 0, 0)">form</span> <span style="box-sizing: border-box;color: rgb(0, 0, 0)">action</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">=</span><span style="box-sizing: border-box;color: rgb(170, 17, 17)">"{{ route('demo.store') }}"</span> <span style="box-sizing: border-box;color: rgb(0, 0, 0)">method</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">=</span><span style="box-sizing: border-box;color: rgb(170, 17, 17)">"POST"</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">></span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(152, 26, 26)"></</span><span style="box-sizing: border-box;color: rgb(0, 0, 0)">form</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">></span></span>
携带参数：如：
{{ route('demo.edit',['id'=>1]) }}
方式二：url函数【次推荐】
<span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(152, 26, 26)"><</span><span style="box-sizing: border-box;color: rgb(0, 0, 0)">form</span> <span style="box-sizing: border-box;color: rgb(0, 0, 0)">action</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">=</span><span style="box-sizing: border-box;color: rgb(170, 17, 17)">"{{ url('demo/store') }}"</span> <span style="box-sizing: border-box;color: rgb(0, 0, 0)">method</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">=</span><span style="box-sizing: border-box;color: rgb(170, 17, 17)">"POST"</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">></span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(152, 26, 26)"></</span><span style="box-sizing: border-box;color: rgb(0, 0, 0)">form</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">></span></span>
方式三：绝对路径【不推荐】
<span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(152, 26, 26)"><</span><span style="box-sizing: border-box;color: rgb(0, 0, 0)">form</span> <span style="box-sizing: border-box;color: rgb(0, 0, 0)">action</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">=</span><span style="box-sizing: border-box;color: rgb(170, 17, 17)">"/demo/store"</span> <span style="box-sizing: border-box;color: rgb(0, 0, 0)">method</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">=</span><span style="box-sizing: border-box;color: rgb(170, 17, 17)">"POST"</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">></span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(152, 26, 26)"></</span><span style="box-sizing: border-box;color: rgb(0, 0, 0)">form</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">></span></span>
到这里，路由-控制器-视图 一系列操作基本完成，就差入库操作。定义路由，显示视图，提交数据，处理数据，已经完成。
URL生成的相关方法
下面案例基于DemoController中的index方法演示。
url方法
<span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(170, 85, 0)">// 将输出 http://你的域名/demo/store</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(119, 0, 136)">echo</span> <span style="box-sizing: border-box;color: rgb(0, 0, 0)">url</span>(<span style="box-sizing: border-box;color: rgb(170, 17, 17)">'/demo/store'</span>);</span>
获取当前url
<span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(170, 85, 0)">// 获取不带请求参数的url</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(119, 0, 136)">echo</span> <span style="box-sizing: border-box;color: rgb(0, 0, 0)">url</span>()<span style="box-sizing: border-box;color: rgb(152, 26, 26)">-></span><span style="box-sizing: border-box;color: rgb(51, 0, 170)">current</span>();</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(170, 85, 0)">// 获取完整url</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(119, 0, 136)">echo</span> <span style="box-sizing: border-box;color: rgb(0, 0, 0)">url</span>()<span style="box-sizing: border-box;color: rgb(152, 26, 26)">-></span><span style="box-sizing: border-box;color: rgb(0, 0, 0)">full</span>();</span>
如有这样一个地址http://baidu.com?id=1,current获取到的是http://www.baidu.com，而full获取到的则是完整的。
生成命名路由地址
echo route('demo.store');
