Are Request Header Parameters Required for Signing Requests?
If you sign API requests by following the instructions in AK/SK Signing and Authentication Algorithm, only X-Sdk-Date is required and other request header parameters are optional.
If you use an SDK provided by Huawei Cloud to sign API requests, you do not need to consider which request header parameters are required. The SDK determines which parameters are required and automatically generates the signature information. If the value of a request header parameter changes after requests are signed, assign a value to the parameter again after signing.
