Generate multiple-files based on different WCF classes or tags

[karimjouini]

Hi,

We are faced with the current issue: a single WCF project has multiple SVCs, and we want a separate json file for each (so we can re-use these as different services/subscriptions for our clients.

Is there a way to set SwaggerWCF to do it ? or an easy way to post-process?

Thanks!

Dear karimjouini, did you manage to find a solution for this? We have faced the same issue recently.

We found a workaround for it.
We used SwaggerWcfTagAttribute to give same tag for same service.
While [SwaggerWcfTag("Mercury")] is used for all operations in ServiceA.svc, [SwaggerWcfTag("Venus")] is used for the ones in ServiceB.svc, etc.

Then we created routes for each tag in Global.asax.
Finally, based on requested url, we have set hidden ones.
I mean that if request is like http://server.com/Mercury-docs, then we set Venus & Earth as hidden.

Here is the code we used in Global.asax.

public class Global : System.Web.HttpApplication
{
private static string[] SwaggerTags = new string[] { "Mercury", "Venus", "Earth" };

protected void Application_Start(object sender, EventArgs e)
{
	SwaggerWcfEndpoint.FilterVisibleTags = FilterVisibleTags;
	SwaggerWcfEndpoint.FilterHiddenTags = FilterHiddenTags;
	SwaggerWcfEndpoint.DisableSwaggerUI = false;

	RouteTable.Routes.Add(new ServiceRoute("api-docs", new WebServiceHostFactory(), typeof(SwaggerWcfEndpoint)));
	foreach(string tag in SwaggerTags)
		RouteTable.Routes.Add(new ServiceRoute($"{tag}-docs", new WebServiceHostFactory(), typeof(SwaggerWcfEndpoint)));
}

private static List<string> FilterVisibleTags(string path, List<string> visibleTags)
{
	if (null != HttpContext.Current)
	{
		string urlPart = HttpContext.Current.Request.Url.AbsolutePath.ToLower();
		foreach (string tag in SwaggerTags)
		{
			if (urlPart.Contains($"{tag.ToLower()}-docs"))
				visibleTags.Add(tag);
		}
	}

	return visibleTags;
}

private static List<string> FilterHiddenTags(string path, List<string> hiddenTags)
{
	if (null != HttpContext.Current)
	{
		string urlPart = HttpContext.Current.Request.Url.AbsolutePath.ToLower();
		foreach (string tag in SwaggerTags)
		{
			if (urlPart.Contains($"{tag.ToLower()}-docs"))
				hiddenTags.AddRange(SwaggerTags.Where(t => !t.Equals(tag)));
		}
	}

	return hiddenTags;
}

}
