Well, that XD, how do I get the IP Address of the querier (if that's even the word xD) from within an operation hook? or a remote hook? (I can save it with loopback.getCurrentContext() to use on the operation hook).
Say:
Model.observe('loaded', function(ctx,next) {
ctx.ip ??
});
So I found this: https://github.com/strongloop/loopback/issues/1495 & this: How to determine a user's IP address in node Great help from both, I just took what I needed to get the address and save it on the loopback current context like this on a startup script:
var loopback = require('loopback');
module.exports = function (app) {
app.remotes().before('*.*', function(ctx,next) {
loopback.getCurrentContext().set('remoteAddress',ctx.req.connection.remoteAddress);
next();
});
app.remotes().before('*.prototype.*', function(ctx,instance,next) {
loopback.getCurrentContext().set('remoteAddress',ctx.req.connection.remoteAddress);
next();
});
};
Then I just get it on an operation hook like this:
Model.observe('loaded', function(ctx,next) {
console.log("Remote Address: ", loopback.getCurrentContext().get('remoteAddress'));
});
Update for Loopback 3: you can get IP address using this property:
ctx.req.connection.remoteAddress
You should also add this code in server.js to grant the real ip, otherwise you´re getting the load balancer IP:
app.set('trust proxy', ['loopback', 'linklocal', 'uniquelocal']);
Not really the question asked, but when you need the ip address from the caller in a remote method, and your nodejs is already behind an Apache proxy (or a well configured nginx one), you can simply
const ip = req.header('X-Forwarded-For')
to get the ip address.
You can get the IP address of the requested user by using the below command.
var ipAddress = context.req.connection.remoteAddress
