openapi3.Unmarshal	Unmarshals the given resource into an OpenAPI 3 document.			aliases related returnType signatures openapi3.OpenAPIDocument openapi3.Unmarshal RESOURCE

Use the openapi3.Unmarshal function with global, page, or remote resources.

For example, to work with a remote OpenAPI definition:

{{ $url := "https://raw.githubusercontent.com/OAI/OpenAPI-Specification/main/examples/v3.0/petstore.json" }}
{{ $api := "" }}
{{ with resources.GetRemote $url }}
  {{ with .Err }}
    {{ errorf "%s" . }}
  {{ else }}
    {{ $api = . | openapi3.Unmarshal }}
  {{ end }}
{{ else }}
  {{ errorf "Unable to get remote resource %q" $url }}
{{ end }}

To inspect the data structure:

<pre>{{ debug.Dump $api }}</pre>

To list the GET and POST operations for each of the API paths:

{{ range $path, $details := $api.Paths }}
  <p>{{ $path }}</p>
  <dl>
    {{ with $details.Get }}
      <dt>GET</dt>
      <dd>{{ .Summary }}</dd>
    {{ end }}
    {{ with $details.Post }}
      <dt>POST</dt>
      <dd>{{ .Summary }}</dd>
    {{ end }}
  </dl>
{{ end }}

Hugo renders this to:

<p>/pets</p>
<dl>
  <dt>GET</dt>
  <dd>List all pets</dd>
  <dt>POST</dt>
  <dd>Create a pet</dd>
</dl>
<p>/pets/{petId}</p>
<dl>
  <dt>GET</dt>
  <dd>Info for a specific pet</dd>
</dl>
