找不到Laravel类'App \ Http \ Controllers \ GuzzleHttp \ Client'
我已经安装了客户端，并使用 composer dump autoload 进行了更新，但仍然出现相同的错误.通过composer安装后，在项目目录中需要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 GuzzleHttp\Client();
为什么工作，为什么甚至引用错误的目录?
Why isn' it working and why is it even referencing the wrong directory?
您将要熟悉PHP Laravel中的大多数文件都已命名.对命名空间中的函数的调用从该命名空间开始，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:
如果以\开头类名，则告诉PHP从根级名称空间开始
If you start the class name with a \, that tells PHP to start at the root-level namespace:
$client = new \GuzzleHttp\Client();
或者，您可以输入:
use GuzzleHttp\Client;
位于文件顶部(您会在Laravel的所有默认文件中看到其中的很多个)，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();
