negroni-logrus
logrus middleware for negroni
Usage
Take a peek at the basic example or the custom
example, the latter of which includes setting a
custom log level on the logger with NewCustomMiddleware.
If you want to reuse an already initialized logrus.Logger, you should be using
NewMiddlewareFromLogger (see existinglogrus).
Note on client IP spoofing
This package tries to figure out the client IP address when sitting behind a proxy
or load-balancer (e.g. AWS ELB). It first inspects the X-Real-IP header, followed
by inspecting the X-Forwarded-For header.
These headers are typically added by your proxy or load-balancer. The X-Forwarded-For
header can contain multiple IP addresses because every proxy or load-balancer will add
another entry. This means that a client can try to spoof the original IP address by
calling your service with an X-Forwarded-For header present.
If this is a genuine concern for you, then you might want to implement your own Before Hook to deal with this. This package can't do this for you because everyone's environment will look differently.
