nginx response code ändern von 413

Question

Gibt es eine Möglichkeit, den Antwortcode nginx sends zu ändern? Wenn der Server eine Datei empfängt, die seine client_max_body_size überschreitet, wie in der Konfiguration definiert, kann ich einen 403-Code anstelle eines 413-Codes zurückgeben lassen?

Answer 1

arbeitet Below gut für mich

events { 
    worker_connections 1024; 
} 
http { 
server { 
    listen 80; 

    location @change_upload_error { 
     return 403 "File uploaded too large"; 
    } 

    location /post { 
     client_max_body_size 10K; 
     error_page 413 = @change_upload_error; 
     echo "you reached here"; 
    } 
} 

}
