Node/Nginx, 413 request entity too large, client_max_body_size set

问题

Pretty similar to https://serverfault.com/questions/539466/413-request-entity-too-large-client-max-body-size-is-set

I've got a Node server (using Loopback) running on top of nginx (to be specific, the dockerfile/nginx image), but whenever I do a large PUT (or POST) request to the Node server, I get back a 413 response.

I've set client_max_body_size (for me, in /etc/nginx/nginx.conf) in a number of places and to exorbitant values and yet still get the 413s... is there something I'm missing?

回答1:

Thanks to Xavier Lucas, problem was indeed with the app and not the nginx config, as suggested in this Github issue:

https://github.com/strongloop/loopback/issues/690

Resolved by setting json and urlencoded limits explicitly.

回答2:

I meet the same error, my node server use the koa-bodyparser, it limit the urlencoded body:

formLimit: limit of the urlencoded body. If the body ends up being larger than this limit, a 413 error code is returned. Default is 56kb.

It is nothing to do with nginx.
