Apache OpenWhisk serverless-upstream plugin (openwhisk).
Port of APISIX’s openwhisk plugin (3.17). Invokes an OpenWhisk action
(blocking, with the result inlined) and returns the action’s reply as the
gateway response — it replaces the upstream, so the node’s success
port should be wired straight to client.in.
The request body is POSTed as the action parameters to
<api_host>/api/v1/namespaces/<namespace>/actions/<package/><action>?blocking=true&result=<result>&timeout=<ms>
with an Authorization: Basic <base64(service_token)> header.
api_host, namespace, package, and action support
{{namespace.path}} references (plain render, no legacy $var
interpolation) — the endpoint is rebuilt per request so a value like
{{request.headers.x-tenant}} in namespace routes each request to a
different OpenWhisk namespace. authorization (built from
service_token) is never templated — it is a credential, not an
endpoint field. namespace/package/action are percent-encoded at
render time before insertion into the URL path (see
encode_path_segment); api_host is not encoded (see its field doc).
§Response mapping
OpenWhisk returns a JSON envelope. An action may return just a body, or set
statusCode and headers explicitly. map_response mirrors APISIX:
statusCode (when present) becomes the response status, headers are
applied, and body (or the raw envelope when absent) becomes the body. A
non-JSON envelope fails the node with 503 through the error port.
Structs§
- Mapped
Response 🔒 - The status, headers, and body mapped out of an OpenWhisk envelope.
- Open
Whisk Plugin - Invokes an OpenWhisk action and maps its reply into
Context.response.
