Portanto, estou ciente de que o stackoverflow é elaborado com essas perguntas sobre o CORS Nginx, Cloudfront e Heroku, mas por alguma razão não consigo fazê-lo funcionar. Tenho acompanhado a resposta desta pergunta:

Como eu configuro `Access-Control-Allow-Origin` com trilhos, nginx e passageiro?

No entanto, não consigo descobrir onde colocar o bloco de código personalizado:

config/nginx.conf.erb

Em seguida, edite o arquivo de configuração config / nginx.conf.erb localizando um bloco com a seguinte aparência:

location @static_asset {
    gzip_static on;
    expires max;
    add_header Cache-Control public;
    add_header ETag "";
} ...and add the two Access-Control lines:

para

>     location @static_asset {
>         gzip_static on;
>         expires max;
>         add_header Cache-Control public;
>         add_header ETag "";
>         add_header Access-Control-Allow-Origin *;
>         add_header Access-Control-Request-Method *;
>     } That's it. This will work in production, but not in development, due to config.assets differences between the two.

na minha configuração do Nginx. Estou usando o Phusion Passenger 5.0.23. A configuração do Nginx não tem um bloco de localização @static_asset no local que puxei do passageiro. Ele possui uma seção para configurações personalizadas, mas que não funcionou para mim. Meus glyphicons continuam aparecendo como caixas Como faço para funcionar? Eu também tentei issoPhusion Passenger + Heroku + Cloudfront: configuração do CORS

#  Passenger Standalone.

#  This file is the original template. DO NOT EDIT THIS FILE DIRECTLY.
#  Instead, make a copy of this file and pass the `--nginx-config-template`
