oauth2-redirect.html with query parameters return 404

[rytsh]

Hi, when I try to login oauth2 feature, it is redirection to this URL:

http://localhost:3000/swagger/oauth2-redirect.html?state=U3X..

But when I checked, if any query parameters go to this html oauth2-redirect.html route not found and return 404.

This should be bug and need to fix the route, serve steps.

v1.3.5 works fine with oauth2 redirection.

I faced the same issue, the bug is in default case of switch statement of swagger.go, line 191

I suggest creating a fork and changing code in default case to:

parsedUrl, err := url.Parse(matches[2])
if err != nil {
    c.Error(err)

    return nil
}
c.Request().URL = parsedUrl
http.FileServer(http.FS(swaggerFiles.FS)).ServeHTTP(c.Response(), c.Request())

BTW: this issue is mentioned also here: swaggo/swag#1117
