以后的编辑：现在可以了，我们收到了一位Here工程师的回复。
即使凭据和代码有效且订阅处于活动状态，因为今天我们在尝试计算路线时也会遇到问题。
使用的API-https://js.api.here.com/v3/3.0/mapsjs-core
响应为：
H.service.jsonp.handleResponse(12)({_type: "ns2:RoutingServiceErrorType", type: "PermissionError", subtype: "InvalidCredentials",…});
details: "These credentials do not authorize access. Please contact your customer representative or submit a request here https://developer.here.com/contact-us to upgrade your account. You can also get valid credentials by registering for a free trial license on https://developer.here.com."
metaInfo: {timestamp: "2019-03-07T08:32:57Z", mapVersion: "8.30.93.157", moduleVersion: "7.2.201909-2305",…}
subtype: "InvalidCredentials"
type: "PermissionError"
_type: "ns2:RoutingServiceErrorType"
知道为什么会这样吗？
