Getting 404 for CSS and JS files

[applejag]

The CSS & JS files all respond with 404. Even using the example from the README.md I still get the same results.

gin-swagger/README.md

Lines 99 to 136 in b9e926c

	package main
	import (
	"github.com/gin-gonic/gin"

	g.JSON(http.StatusOK,"helloworld")
	}

	docs.SwaggerInfo.BasePath = "/api/v1"
	v1 := r.Group("/api/v1")

	eg := v1.Group("/example")
	{
	eg.GET("/helloworld",Helloworld)
	}
	}
	r.GET("/swagger/*any", ginSwagger.WrapHandler(swaggerfiles.Handler))
	r.Run(":8080")
	}

Maybe related: swaggo/http-swagger#10, don't know if the issue is in this codebase or in some dependency, but it's not working here as well.

you can get in ginswagger.WrapHandler -> CustomWrapHandler
you can see once.Do(func() {
handler.Prefix = matches[1]
})
and handler.ServeHTTP(c.Writer, c.Request), that means when the first request url is where .js、.css in, so you have to use the same url as the first request url or replace /swagger/*any with a specific route
