relative url for links object

[luke-zhang]

is there a way to return relative url for links object. in our projects, we'd like to see this
"links": { "self": "/api/sessions" },
instead of
"links": { "self": "http://localhost:49895/api/sessions" },

This is not possible at the moment, but I'm open to a PR to allow this.

The request URI comes from here:

saule/Saule/Http/PreprocessingDelegatingHandler.cs

Line 59 in 41c9b84

return jsonApi.PreprocessContent(content, resource, request.RequestUri);

It's then passed into the serializer here:

saule/Saule/JsonApiSerializer.cs

Line 73 in 41c9b84

baseUrl: requestUri,

It's prepended to every generated path here:

saule/Saule/Serialization/ResourceSerializer.cs

Line 318 in 41c9b84

var start = new Uri(_baseUrl.GetLeftPart(UriPartial.Authority).EnsureEndsWith("/"));

I think a property GenerateRelativeUrls in JsonApiSerializer (default value: false) is a nice backwards-compatible spot to put this.

@joukevandermaas thanks a lot for your help. I am thinking if IUrlPathBuilder is better than JsonApiSerializer to place this property since it can be customized easily.

I agree with you, but it currently does not have this behavior. So that would be breaking backwards compatibility. If you can think of a way to not break existing stuff, I'm all for it.
