我已经设置了浏览器API密钥，并在referrer部分添加了“ .mydomain.com / ”。点击保存，等待5分钟。
执行和API调用时，我收到以下错误：
Array
(
[error] => Array
(
[errors] => Array
(
[0] => Array
(
[domain] => usageLimits
[reason] => ipRefererBlocked
[message] => The referrer null does not match does not match the referrer restrictions configured on your API key. Please use the API Console to update your key restrictions.
[extendedHelp] => https://console.developers.google.com/apis/credentials?project=xxxxxxxxx
)
)
[code] => 403
[message] => The referrer null does not match does not match the referrer restrictions configured on your API key. Please use the API Console to update your key restrictions.

如果我将引荐来源部分留在Google开发者控制台中，那么一切正常。我是否还需要在某处的代码中指定引荐来源？
使用https://github.com/yiisoft/yii2-httpclient拨打电话：
$path = 'https://www.googleapis.com/youtube/v3/channels';
$response = $this->client->createRequest()
->setMethod( 'get' )
->setUrl( $path )
->setData( [ 'key' => $this->key, 'part' => 'id', 'forUsername' => $user_handle ] )
->send();
发送：
GET https://www.googleapis.com/youtube/v3/channels?part=id&forUsername={USER_NAME}&key={YOUR_API_KEY}
