Short Version: You're trying to instantiate a class that doesn't exist. Instantiate the right class and you'll be all set.
简短版本：您正在尝试实例化一个不存在的类。实例化正确的类，你就可以了。
Long Version: You shouldn't need to do anything fancy with your composer.json to get Guzzle working. Guzzle adheres to a the PSR standard for autoloading, which means so long as Guzzle's pulled in via composer, you can instantiate Guzzle classes without worrying about autoloading.
长版：你不需要对你的 composer.json 做任何花哨的事情来让 Guzzle 工作。Guzzle 遵守自动加载的 PSR 标准，这意味着只要 Guzzle 通过 Composer 引入，您就可以实例化 Guzzle 类而无需担心自动加载。
Based on the file path you mentioned, it sounds like you're using Guzzle 3. Looking specifically at the class you're trying to include
根据您提到的文件路径，听起来您正在使用 Guzzle 3。专门查看您要包含的课程
namespace Guzzle\Http;
/*...*/
class Client extends AbstractHasDispatcher implements ClientInterface
{
/*...*/
}
The guzzle client class in Guzzle 3 is not GuzzleHttp\Client. Its name is Guzzle\Http\Client. So try either
Guzzle 3 中的 Guzzle 客户端类不是GuzzleHttp\Client. 它的名字是Guzzle\Http\Client。所以尝试
$client = new \Guzzle\Http\Client;
or
或者
use Guzzle\Http\Client;
$client = new Client;
and you should be all set.
你应该准备好了。
