Class "Symfony\Bridge\PsrHttpMessage\Factory\HttpFoundationFactory" not found

出现上面的问题，主要是缺失下面两个包

在项目根目录直接执行下面的命令即可

# composer require symfony/psr-http-message-bridge
# composer require nyholm/psr7

代码里的使用例子

$client = new GuzzleHttpClient(['base_uri' => 'http://api.tvmaze.com/']);

$res = $client->request('GET', '/schedule?country=US&date=2014-12-01');

return $res;
