Nginx Net :: ERR_INCOMPLETE_CHUNKED_ENCODING en essayant de montrer un grand JSON

Question

Bonjour, Je suis en train de montrer un grand JSON en utilisant php mais quand fichier JSON est grand et je reçois Net::ERR_INCOMPLETE_CHUNKED_ENCODING voir

«/var/lib/nginx/FastCGI/1/00 ​​/ 0000000001" a échoué (13: autorisation refusée ) lors de la lecture en amont

dans mon journal nginx.

Mon serveur nginx démarre à partir de l'utilisateur www-data.

aussi mon php-fpm7 fonctionne également sous forme www-data

/var/lib/nginx/appartenant également à www-data.

ls -l nginx

drwxrwxrwx 2 www-data www-data 4096 Aug 21 21:35 uwsgi 

limite de mémoire php est 512m limite du corps nginx est 100m

le serveur exécute usign docker.

Que peut-être tort?

Answer 1

Enfin corrigé en supprimant le répertoire/var/lib/nginx/fastcgi, puis en le recréant à partir de root et en changeant son propriétaire en www-data.

maintenant il ressemble que

drwxr-xr-x 2 www-data root  4096 Sep 5 13:58 fastcgi 

De plus, le problème pourrait être résolu en ajustant la taille de la mémoire tampon de FastCGI en utilisant ces paramètres de configuration:

fastcgi_buffers 16 16k; 
    fastcgi_buffer_size 32k;
