为Laravel应用引入了由Composer提供的类加载器，这样Laravel应用便无需再手动加载任 何的类。其加载原理不是此次探究的目标，所以仅仅这样使用就好了。接下的代码，便是重 点。
Illuminate\Foundation\Application 类
该类的继承结构如下：

它将我的视线引入到了另外一个文件中，去看看到底发生了什么吧。

看第十四行，原来$app是一个 Illuminate\Foundation\Application 对象，那么在创 建这个对象的时候又发生了什么呢？
从它的构造方法看起：

顺着函数调用，往下看。在这个构造函数中，首先调用了registerBaseBindings方法。
Illuminate\Foundation\Application#registerBaseBindings

这段代码，是将实例对象注入到容器中。那么，这个容器是什么呢？答案还是要从这段调用 中去寻找。
static::setInstance($this) 所做的就是将 $this 赋值给自身的 instance 静态变 量。重点看 $this->instance('app', $this)。
instance 函数的作用是绑定一个已有对象到容器中，这个对象在容器中共享并且可以通 过键获取。
Illuminate\Container\Container#instance

视线重新回到Application类中，接下来调用了这个方法 $this->registerBaseServiceProviders()，
Illuminate\Foundation\Application#registerBaseServiceProviders

其中，EventServiceProvider和RoutingServiceProvider分别是
Illuminate\Events\EventServiceProviderIlluminate\Routing\RoutingServiceProvider
这些ServiceProvider是 Illuminate\Support\ServiceProvider 的子类，它接受一个 Application 对象作为构造函数参数，存储在实例变量 $app 中。
注入所有基础 Service Provider
在 register 方法中，每个ServiceProvider被调用了自身的 register 方法。首先看 看 EventServiceProvider 中的吧。
Illuminate\Events\EventServiceProvider#register
<span class="line-number">1<span class="line-number">2<span class="line-number">3<span class="line-number">4<span class="line-number">5<span class="line-number">6<span class="line-number">7<span class="line-number">8</span></span></span></span></span></span></span></span> 登入後複製 | <span class="line"><span class="k">public <span class="k">function <span class="nf">register<span class="p">()<span class="line"><span class="p">{<span class="line"> <span class="nv">$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>登入後複製 |
上面方法体将一个 Illuminate\Events\Dispatcher 对象以键 events 绑定到了容器 中，它负责实现事件的调度。
再看看 Illuminate\Routing\RoutingServiceProvider:
Illuminate\Routing\RoutingServiceProvider#register

首页是在Laravel中接触的最多的 route 被注册，它是 Illuminate\Routing\Router 对象。

Aug 24, 2023 am 09:48 AM
為什麼截圖工具在Windows11上不起作用了解問題的根本原因有助於找到正確的解決方案。以下是截圖工具可能無法正常工作的主要原因：對焦助手已開啟：這可以防止截圖工具開啟。應用程式損壞：如果截圖工具在啟動時崩潰，則可能已損壞。過時的圖形驅動程式：不相容的驅動程式可能會幹擾截圖工具。來自其他應用程式的干擾：其他正在運行的應用程式可能與截圖工具衝突。憑證已過期：升級過程中的錯誤可能會導致此issu簡單的解決方案這些適合大多數用戶，不需要任何特殊的技術知識。 1.更新視窗與Microsoft應用程式商店應用程

本篇文章所依賴的python環境為:什麼是WSGIWSGI也稱之為web伺服器通用網關接口，全稱是webservergatewayinterface。它定義了在python中web伺服器與web應用程式之間應該如何通訊並且處理http請求和回應的一個標準，注意，它只是一個協議，或者說是規範、標準，你也可以不按這個標準來，就像我們上一篇文章所寫的web伺服器那樣。 WSGI也分為應用程式和伺服器網關，其中我們熟知的Flask就是屬於應用程序，uWSGI、wsgiref屬於伺服器網關。個人感覺，WSG
如何修復無法連線到iPhone上的App Store錯誤
Jul 29, 2023 am 08:22 AM
第1部分：初始故障排除步驟檢查蘋果的系統狀態：在深入研究複雜的解決方案之前，讓我們先從基礎知識開始。問題可能不在於您的設備;蘋果的伺服器可能會關閉。造訪Apple的系統狀態頁面，查看AppStore是否正常運作。如果有問題，您所能做的就是等待Apple修復它。檢查您的網路連接：確保您擁有穩定的網路連接，因為「無法連接到AppStore」問題有時可歸因於連接不良。嘗試在Wi-Fi和行動數據之間切換或重置網路設定（「常規」>「重置」>「重置網路設定」>設定）。更新您的iOS版本：
