Signature Algorithm

Tip: Our company will provide the accessSecret mentioned below

Sort the parameters in the request in the following order, concatenating them with & (without spaces):

method: needs to be capitalized, such as: POST

url :
Remove the protocol, domain name, and parameters, and prefix them with a /, such as: /api/test/hello
Use the HMAC-SHA256 protocol to create a Hash-based Message Authentication Code (HMAC), using the accessSecret as the key. Calculate the signature of the concatenated parameters and encode the resulting signature in Base-64.
