Go Go Cors Proxy

A simple Go proxy which adds CORS headers to an incoming request. This allows your application to execute requests on a resource hosted on a different domain.

Getting Started

Download and install Go
Setup your $GOROOT and $GOPATH in your bashrc / zshrc, for example:

    export GOROOT=/usr/local/go
    export GOPATH=/dev/go
    export PATH=$PATH:$GOROOT/bin:$GOPATH/bin

Application Flags

Flag	Default	Description
`target`	localhost:8080	host:port to proxy requests to
`listen`	localhost:8181	host:port to listen on
`protocol`	http	protocol used by the target
`host`	localhost:3000	host header to be used for the proxy request
`origin`	`http://localhost:3000`	origin header to be used for the proxy request
`methods`	true	enable / disable default access control methods
`debug`	false	enable / disable debug messages

Running The Application

Once Go has been correctly installed and configured, execute:

go run proxy.go -target=0.0.0.0:8080 -listen=0.0.0.0:8181 -host=localhost:3000 -origin=http://localhost:3000

Now all incoming requests on port 8181 will be proxied to http://0.0.0.0:8080
