如何在JAX-RS中返回http创建的资源的位置以及响应状态消息？

Question

I'm working on a web service that works as follows:

1. The client sends a POST request to the REST server with some parameters.

2. The REST server handles the request, inserts the data to a table, creating a new row with an ID.

3. The REST server then sends a request to the FileServer for uploadlink and the FileServer returns the uploadLink to the REST server.

4. Finally, the REST server returns the location of the newly created resource with ID, from step 2, to the client.

This is the POST handler:

@POST
public Response postFilesByCustomerId(AbstractPrincipal user, Attachment attachment) {
    Integer id = new AttachmentService(user).createNew(attachment);
    String uploadLink = FileServer.getUploadLinkForFile(user.getDB(), attachment.getUuid(), attachment.getFileName());
    return Response.created(LinkBuilder.getUriFromResource(this.getClass(), id)).build();
}

When I send POST request from the client, I get this response:

My question is, How can I include the uploadLink in the response? I'd really appreciate any suggestion or advice, java noob here.

How can I include the uploadLink in the response?

If you intend to send the URI in the payload of the response , you can use the following:

URI uri = LinkBuilder.getUriFromResource(this.getClass(), id);
return Response.created(uri).entity(uploadLink).build();

If you want to add a Link header, try the following:

return Response.created(uri).link(uploadLink, "upload").build();
