提示：Access not granted ，可是我都是在先测试的，没有修改配置的啊
范例都不好使，能否给帮忙看一下， 在先sha512 加密都试过了， 还有获取点阵数据，使用的是哪个api帮忙指定一下
Thank you for contacting us.
Your "access granted" issue is probably due to a wrong hmac computation.
For a detailed REST example set up including the hmac computation, please check this post.
Thank you. It's really the problem of encryption. It's just that it's more difficult to find the steps. Thank you very much
