WebApi Swagger (Swashbuckle) - 通过代理连接时无法访问 Swagger UI

Question

I have a swagger (Swashbuckle) enabled on one of my API controllers.

Server sits on http://192.168.7.119:1001 and Swagger UI is accessed through http://192.168.7.119:1001/swagger .

When connecting locally, everything is fine and I can access Swagger UI on port 1001 as expected. But when trying connect throug proxy on port 1000 (which redirects 1000 to 1001), I get a well known error:

"Can't read from server. It may not have the appropriate access-control-origin settings".

I have read this:

Unable to access swagger despite cors enabled Asp.NET WebAPI

and tried to set the RootUrl manually in Startup file, within Swagger like this:

.EnableSwagger(c => 
         {
             c.RootUrl(req => @"http://192.168.7.119:1001";
             ...
         });

CORS settings are set as:

appBuilder.UseCors(Microsoft.Owin.Cors.CorsOptions.AllowAll);

Any hints what am I doing wrong here?

Putting together this two pages from github repos of Swashbuckle the easy way to do what you're asking is:

• From Github Make sure that your proxy is sending the X-Forwarded-* headers (Apache does it out of the box while Nginx doesn't seems so. You have to do some changes on the nginx conf .
• From Github . Create this HttpRequestMessageExtensions static class with the ComputeHostAsSeenByOriginalClient method and then

.EnableSwagger(c => 
         {
               c.RootUrl(req => req.ComputeHostAsSeenByOriginalClient());
             ...
         });
