Entry file index.php

For an application based on Laravel, when the WEB server receives an external request, it will parse the request to public/index.php in the application root directory.

Introduces the class loader provided by Composer for Laravel applications, so that Laravel applications no longer need to manually load any classes. Its loading principle is not the goal of this study, so just use it this way. The following code is the focus.

IlluminateFoundationApplication class

The inheritance structure of this class is as follows:

It draws my attention to another file to see what is going on.

Look at line 14. It turns out that $app is a IlluminateFoundationApplication object, so what happened when this object was created?

From its construction method:

IlluminateFoundationApplication constructor

Follow the function calls and look down. In this constructor, the registerBaseBindings method is called first.

IlluminateFoundationApplication#registerBaseBindings

This code injects the instance object into the container. So, what is this container? The answer still needs to be found from this call.

What

static::setInstance($this) does is assign $this to its own instance static variable. Focus on $this->instance('app', $this).

The function of

instance is to bind an existing object to the container. This object is shared in the container and can be obtained by key.

IlluminateContainerContainer#instance

The line of sight returned to the Application class, and then this method was called $this->registerBaseServiceProviders(),

Among them, EventServiceProvider and RoutingServiceProvider are respectively

• IlluminateEventsEventServiceProvider
• IlluminateRoutingRoutingServiceProvider

These ServiceProviders are subclasses of IlluminateSupportServiceProvider , which accept a Application object as a constructor parameter, which is stored in the instance variable $app .

Inject all basic Service Providers

In the register method, each ServiceProvider is called its own register method. Let’s take a look at EventServiceProvider first.

IlluminateEventsEventServiceProvider#register

<span class="line-number">1 <span class="line-number">2 <span class="line-number">3 <span class="line-number">4 <span class="line-number">5 <span class="line-number">6 <span class="line-number">7 <span class="line-number">8 </span></span></span></span></span></span></span></span>

<code class="php"><span class="line"><span class="k">public <span class="k">function <span class="nf">register<span class="p">() <span class="line"><span class="p">{ <span class="line"> <span class="nv">$this<span class="o">-><span class="na">app<span class="o">-><span class="na">singleton<span class="p">(<span class="s1">'events'<span class="p">, <span class="k">function <span class="p">(<span class="nv">$app<span class="p">) <span class="p">{ <span class="line"> <span class="k">return <span class="p">(<span class="k">new <span class="nx">Dispatcher<span class="p">(<span class="nv">$app<span class="p">))<span class="o">-><span class="na">setQueueResolver<span class="p">(<span class="k">function <span class="p">() <span class="k">use <span class="p">(<span class="nv">$app<span class="p">) <span class="p">{ <span class="line"> <span class="k">return <span class="nv">$app<span class="o">-><span class="na">make<span class="p">(<span class="s1">'Illuminate\Contracts\Queue\Factory'<span class="p">); <span class="line"> <span class="p">}); <span class="line"> <span class="p">}); <span class="line"><span class="p">} </span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></code>

The above method body binds a IlluminateEventsDispatcher object to the container with the key events, which is responsible for event scheduling.

Look again IlluminateRoutingRoutingServiceProvider:

IlluminateRoutingRoutingServiceProvider#register

<span class="line-number">1 <span class="line-number">2 <span class="line-number">3 <span class="line-number">4 <span class="line-number">5 <span class="line-number">6 <span class="line-number">7 <span class="line-number">8 <span class="line-number">9 <span class="line-number">10 <span class="line-number">11 <span class="line-number">12 <span class="line-number">13 <span class="line-number">14 </span></span></span></span></span></span></span></span></span></span></span></span></span></span>

<code class="php"><span class="line"><span class="k">public <span class="k">function <span class="nf">register<span class="p">() <span class="line"><span class="p">{ <span class="line"> <span class="nv">$this<span class="o">-><span class="na">registerRouter<span class="p">(); <span class="line"> <span class="line"> <span class="nv">$this<span class="o">-><span class="na">registerUrlGenerator<span class="p">(); <span class="line"> <span class="line"> <span class="nv">$this<span class="o">-><span class="na">registerRedirector<span class="p">(); <span class="line"> <span class="line"> <span class="nv">$this<span class="o">-><span class="na">registerPsrRequest<span class="p">(); <span class="line"> <span class="line"> <span class="nv">$this<span class="o">-><span class="na">registerPsrResponse<span class="p">(); <span class="line"> <span class="line"> <span class="nv">$this<span class="o">-><span class="na">registerResponseFactory<span class="p">(); <span class="line"><span class="p">} </span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></code>

首页是在Laravel中接触的最多的 route 被注册，它是 IlluminateRoutingRouter 对象。
