Construct a Canonical Request
Construct a Canonical Request from request elements
canonical_request( verb, canonical_uri = "", query_args = list(), canonical_headers, request_body = "", signed_body = FALSE )
verb |
A character string containing the HTTP verb being used in the request. |
canonical_uri |
A character string containing the “canonical URI”, meaning the contents of the API request URI excluding the host and the query parameters. |
query_args |
A named list of character strings containing the query string values (if any) used in the API request. |
canonical_headers |
A named list of character strings containing the headers used in the request. |
request_body |
The body of the HTTP request, or a filename. If a filename, hashing is performed on the file without reading it into memory. |
signed_body |
Sign the body request and add the correct header (x-amz-content-sha256) to the list of headers |
This function creates a “Canonical Request”, which is part of the Signature Version 4. Users probably only need to use the signature_v4_auth function to generate signatures.
