Servidor Express: Error: Rango solicitado no satisfactorio

Question

Estoy escribiendo mi primer servidor web nodo (no dude en darme su opinión) que utiliza express y gith para implementar. El problema es que recibo el siguiente error una vez que se despliega, y si ejecuto el script a través de pm2 el proceso aparentemente se elimina. ¿Algunas ideas? El script se adjunta a continuación.

sudo node server.js

Answer 1

¿No deberías usar require(''https'') ? También investigue express.static ...

Answer 2

Parece que el error está saliendo de su script deploy.sh.

Para solucionar esto, asegúrese de que las solicitudes salientes no tengan el Content-Range .

También podría ayudar a publicar el deploy.sh

Answer 3

Intente pasar acceptRanges: false como argumento al método res.sendFile.

Entonces, en lugar de llamar a res.sendFile(filePath) use res.sendFile(filePath, {acceptRanges: false})
