Incorrect HTTP method in response message and duplicate Link header when creating a container

curl -iX POST -H'Link: <http://www.w3.org/ns/ldp#BasicContainer>; rel="type"' https://example.org/

HTTP/2 415
link: <.acl>; rel="acl", <.meta>; rel="describedBy", <http://www.w3.org/ns/ldp#Container>; rel="type", <http://www.w3.org/ns/ldp#BasicContainer>; rel="type"

PUT request require a valid content type via the Content-Type header

Note POST request but PUT in response message.

curl -iX POST -H'Content-Type: text/turtle' -H'Link: <http://www.w3.org/ns/ldp#BasicContainer>; rel="type"' https://example.org/

HTTP/2 201
location: /c4db39a0-2bc3-11ea-b34b-d1f743b7eb53/
link: <.acl>; rel="acl", <.meta>; rel="describedBy", <http://www.w3.org/ns/ldp#Container>; rel="type", <http://www.w3.org/ns/ldp#BasicContainer>; rel="type", <http://www.w3.org/ns/ldp#BasicContainer>; rel="type"

Created

Note duplicate LDP-BC rel=type. Same as https://github.com/solid/node-solid-server/issues/426

首先重现 issue 中的两个 POST 请求，并跟踪 NodeJS 服务器中容器创建的 HTTP 处理流程。确认错误消息指明的是 POST 而不是 PUT，并确认响应在 Link 标头中仅发出一次 LDP BasicContainer 类型。
