The %s format suggests that the string is null-terminated, which is not the case for r->uri.data. There's a special format %V for printing ngx_str_t: ngx_log_debug1(NGX_LOG_DEBUG_HTTP, log, 0, "%V", &r->uri); For more information on ngx_str_t, see the dev guide: http://nginx.org/en/docs/dev/development_guide.html#strings > Posted at Nginx Forum: > https://forum.nginx.org/read.php?2,285729,285729#msg-285729 > > _______________________________________________ > nginx mailing list > nginx@nginx.org > http://mailman.nginx.org/mailman/listinfo/nginx -- Roman Arutyunyan _______________________________________________ nginx mailing list nginx@nginx.org http://mailman.nginx.org/mailman/listinfo/nginx
