In June 2016Google announced that they would stop supporting keyless usage, meaning any request that doesn't include an API key or Client ID. This will go into effect on June 11 2018, and keyless access will nolonger be supported

2016年 6月，Google 宣布他们将停止支持无密钥使用，这意味着任何不包含 API 密钥或客户端 ID 的请求。这将生效于2018年6月11日，和无钥匙进入将不会再支持
