Question
POST request to server doesn't work after some size
I have successfully deployed my R plumber file to digital ocean ubuntu-s-1vcpu-2gb-fra1-01. The API works as expected, but I have a problem when I try to send large files through the network. For example, I can send a vector (which is probably internally transformed to json) of the size 100.000, but I can’t send the vector of the size 200.000. Since vector of the size > 100.000 is normal in data science, is it possible to somehow change server configs to allow for greater files?

Hi @MislavSag,
The post size limit is based on the WebService you are using - Apache/Nginx or something else entirely. Anyway, there are limits in each WebService you can adjust to increase the maximum allowed size of a post request. For instance if you are using Apache the limit is set via the
LimitRequestBodydirective and defaults to 0:This directive specifies the number of bytes from 0 (meaning unlimited) to 2147483647 (2GB) that are allowed in a request body.
If you are using Nginx, you can use the
client_max_body_sizedirectiv in your Nginx config -nginx.conf.This directive can also be added in
conf.dfolder, so that system updates will not conflict with modified nginx.conf. In such a case, we can save the file as/etc/nginx/conf.d/uploads.confand it will be automatically included in the server configuration. The name is not really important here, it just need to end with .conf. When using a separate file, the wrapping http part must be omitted, as it will be included in http block, the file should only contain the upload size directive:Regards, KFSys
@KFSys, sorry for the really late answer. Could you please explain how can I create conf file and add it to
etc/nginx/conf.d/uploads.conf? I don’t usually use ubuntu, so I am not sure how to do that.
