## 实例化http应用
在入口文件中是通过App类来实例化http应用的。`$http = (new App())->http`。App类是继承Container容器类。则可以通过容器的方式对http进行实例化。先是初始化App类。设置了项目的类库目录。并将自定义的容器标识绑定到容器。
```
public function __construct(string $rootPath = ''){
// 系统核心框架目录
$this->thinkPath = dirname(__DIR__) . DIRECTORY_SEPARATOR;
// 应用根目录
$this->rootPath = $rootPath ? rtrim($rootPath, DIRECTORY_SEPARATOR) . DIRECTORY_SEPARATOR : $this->getDefaultRootPath();
// app目录
$this->appPath = $this->rootPath . 'app' . DIRECTORY_SEPARATOR;
// 运行时文件 runtime 目录
$this->runtimePath = $this->rootPath . 'runtime' . DIRECTORY_SEPARATOR;
// 绑定标识到容器
if (is_file($this->appPath . 'provider.php')) {
$this->bind(include $this->appPath . 'provider.php');
}
// 设置容器对象实例
static::setInstance($this);
// 设置容器中的对象实例
$this->instance('app', $this);
$this->instance('think\Container', $this);
}
```
