问题描述
我已经安装了客户端并使用 composer dump autoload 进行了更新，但我仍然遇到同样的错误.通过 composer 安装后在项目目录下需要 guzzlehttp/guzzle:~6.0.
I've installed the client and I did an update using composer dump autoload but I still end up with the same error. After installing via composer require guzzlehttp/guzzle:~6.0 in the projects directory.
$client = new GuzzleHttpClient();
为什么它不起作用，为什么它甚至引用了错误的目录?
Why isn' it working and why is it even referencing the wrong directory?
推荐答案
你会想要熟悉 PHP 命名空间.
You're going to want to get acquainted with PHP namespaces.
Laravel 中的大多数文件都是命名空间的.对命名空间内的函数的调用始于该命名空间内，但有两个例外:
Most files in Laravel are namespaced. Calls to functions within a namespace start within that namespace, with two exceptions:
如果你用 开始类名，这告诉 PHP 从根级命名空间开始:
If you start the class name with a , that tells PHP to start at the root-level namespace:
$client = new GuzzleHttpClient();
或者，你可以说:
use GuzzleHttpClient;
在文件的顶部(你会在 Laravel 的默认文件中看到很多 文件)然后执行
at the top of the file (you'll see a lot of these already throughout Laravel's default files) and then do
$client = new Client();
