uwsgi 配置

web-04 的nemu-api uwsgi 配置

[uwsgi]

#  worker关闭或reload的时间，有仲情况是，worker关闭要太长时间了，导致一直关不掉
worker-reload-mercy = 10 
#Set the max size of a request (request-body excluded), this generally maps to the size of request headers.  设置requset大小，不包括request body，
#一般指request的header，cookie，请求参数

buffer-size:
Set the max size of a request (request-body excluded), this generally maps to the size of request headers. By default it is 4k. If you receive a bigger request (for example with big cookies or query string) you may need to increase it. It is a security measure too, so adapt to your app needs instead of maxing it out.
