here.com API oAuth凭证

如何解决here.com API oAuth凭证

我正在测试here.com的位置REST API。我已经在开发人员门户中设置了REST oAuth凭据，并已通过Postman成功请求了oAuth令牌。当我尝试在燃油价格API中使用令牌时，收到错误消息：

        "These credentials do not authorize access"

oAuth POST请求：

Authorization: OAuth oauth_consumer_key="wD7h-u8jE03c0jRu2m4XBQ",oauth_signature_method="HMAC-SHA256",oauth_timestamp="1600812281",oauth_nonce="npygZT9FJ9f",oauth_version="1.0",oauth_signature="fM6AsYnp9jKHlY6ESyKwUwqIHQik4ad6spUeiWAh2ag%3D"

解决方法

不幸的是，目前Freemium计划无法访问联网汽车服务https://developer.here.com/documentation#cvs

在https://developer.here.com/documentation/fuel-prices/dev_guide/topics/credentials.html上，您可以看到：

有两种凭证：

开发凭证-这些凭证用于评估和发展。要获取您的开发凭据，请联系您客户/销售代表并签署适当的评估协议。
生产凭证-这些凭证用于商业用途部署。要获取您的商业凭证，请在适当的商业协议。您必须完成所有测试，准备部署并签署了广告协议，然后再申请生产证书。

您还可以阅读此知识库What other HERE Location Services limits apply to my Freemium or Pro plan?-稍后将添加有关车联网服务的信息。
