This is a simple b2 client used to retrieve objects from Backblaze B2 via its Native API.

#Status

The code has been updated to support compiler:

Client represents an authorized b2 client.

Client::consume_object

source

fn Client::consume_object(self : Client, filename : String, hash~ : &@gmlewis/spin-moonbit-sdk/common.HashFunc
HashFunc?, debug? : Bool) -> String raise ClientError

consume_object performs a GET to retrieve the b2 object, consumes it and optionally returns the object's hash using the provided HashFunc.

Client::get_download_authorization_url

source

fn Client::get_download_authorization_url(self : Client, file_name_prefix : String, valid_duration_in_seconds? : Int, debug? : Bool) -> String raise ClientError

get_download_authorization_url returns a URL that can be used in an https GET call to download any files in a bucket with the given file_name_prefix. Note that if file_name_prefix needs to be escaped for suitability within a query parameter, you must do that first before calling this function.

Client::new

source

fn Client::new(key_id : String, key_secret : String, bucket_id : String, bucket_name : String, debug? : Bool) -> Client raise ClientError

Client::new returns a new client to communicate with the b2 (Backblaze) API for the provided bucket_id and bucket_name.

Client::stream_object

source

fn Client::stream_object(self : Client, filename : String, response_out : @gmlewis/spin-moonbit-sdk/interface/wasi/http/types.ResponseOutparam
ResponseOutparam, hash~ : &@gmlewis/spin-moonbit-sdk/common.HashFunc
HashFunc?, debug? : Bool) -> String raise ClientError

stream_object performs a GET to retrieve the b2 object, streams it to its https response_out, and optionally returns the object's hash using the provided HashFunc.
