gxthrj opened a new issue #2336:
URL: https://github.com/apache/apisix/issues/2336
### Issue description
We’d better change the organization of `signing_string` for hmac-auth
```
signing_string = HTTP Method + \n
+ HTTP URI + \n +
+ canonical_query_string + \n +
+ x-hmac-access-key + \n +
+ Date + \n +
+ x-hmac-signed-headers
```
Use `\n` interval between fields, if `x-hmac-signed-headers` is empty, you
don’t need to add `\n`, if other fields are empty, you need to keep`\n`
The key assembly method specified by `x-hmac-signed-headers`:
```
HeaderKey1 + ":" + HeaderValue1 + "\n"\+
HeaderKey2 + ":" + HeaderValue2 + "\n"\+
...
HeaderKeyN + ":" + HeaderValueN + "\n"
```
