title: How to make a route prefix of swagger in abp vnext
body: <p>I am using abp vnext with .net 6. I try to access the swagger ui like https://{server}:{port}/{virtualPath}/swagger/index.html, because I want to use nginx with 2nd dir. My code like this:</p>
  <pre><code> app.UseSwagger(c =&gt;
          {
              c.PreSerializeFilters.Add((swaggerDoc, httpReq) =&gt; {
                  swaggerDoc.Servers = new List&lt;OpenApiServer&gt; { new OpenApiServer { Url = $&quot;{vPath}&quot;
                  } };
  
              });
          });
   app.UseAbpSwaggerUI(c =&gt;
          {
              c.SwaggerEndpoint($&quot;{vPath}/swagger/v1/swagger.json&quot;, &quot;Demo API&quot;);
          }
  </code></pre>
  <p>but it does not work.</p>
