Laravel 5 Basics (2) - Introduction to Routing, Controllers and Views

• View app/Http/routes.php

<code>Route::get('/', 'WelcomeController@index');</code>

@ is a delimiter, preceded by the controller and followed by the action, which means that when the user requests url /, the index method in the controller WelcomeController is executed

• app/http/controllers/welcomecontroller.php

<code>public function index()
{
return view('welcome');
}</code>

Currently, a view is returned by default. The name of the view is welcome, which is actually welcome.blade.php. Blade is the view template of laravel.

• You can view `resources/views/welcome.blade.php

• Modify welcomecontroller.php

<code>public function index()
{
//    return view('welcome');
return 'hello, laravel';
}</code>

<code>在浏览器中测试，得到一个简单的反馈。</code>

• We create a new route and add:
in routes.php

<code>Route::get('/contact', 'WelcomeController@contact');</code>

You can create a new route, but for now we still use the default controller directly and add:

in WelcomeController.php

<code>public function contact() {
    return 'Contact Me';
}</code>

<code>在浏览器终测试新增加的路由。</code>

• We can return a simple string, or a json or html file. All view files are stored in resource->views.
  For example: return view('welcome') , we don't need to consider the path, and don't add the .blade.php extension, the framework does it for us automatically. If you need a subdirectory in the views directory, such as the views/forum subdirectory, just return view('forum/xxx'), or the simple and clear way is: return view('forum.xxx') . ??

• We return to a page

<code>public function contact() {
    return view('pages.contact');
}</code>

• Create the pages directory under the views directory, and then create contact.blade.php

<code>&lt;!doctype html&gt;
&lt;html lang=&quot;en&quot;&gt;
&lt;head&gt;
    &lt;meta charset=&quot;UTF-8&quot;&gt;
    &lt;title&gt;Document&lt;/title&gt;
&lt;/head&gt;
&lt;body&gt;
&lt;h1&gt;Contact&lt;/h1&gt;
&lt;/body&gt;
&lt;/html&gt;</code>
