答案 0 :(得分:0)
Google Maps API不允许未经身份验证的请求,并且需要使用API密钥。
如果您打开JavaScript控制台,您将看到以下条目:
路线服务:此服务需要API密钥。有关身份验证和Google Maps Javascript API服务的详细信息,请参阅:https://developers.google.com/maps/documentation/javascript/get-api-key
Google Maps API警告:NoApiKeys https://developers.google.com/maps/documentation/javascript/error-messages#no-api-keys
Google Maps API警告:SensorNotRequired https://developers.google.com/maps/documentation/javascript/error-messages#sensor-not-required
