### Extensions to the "os" package.
## Find the current Executable and ExecutableFolder.
There is sometimes utility in finding the current executable file
that is running. This can be used for upgrading the current executable
or finding resources located relative to the executable file.
Multi-platform and supports:
* Linux
* OS X
* Windows
* Plan 9
* BSDs.

# Go CORS handler [![godoc](http://img.shields.io/badge/godoc-reference-blue.svg?style=flat)](https://godoc.org/github.com/rs/cors) [![license](http://img.shields.io/badge/license-MIT-red.svg?style=flat)](https://raw.githubusercontent.com/rs/cors/master/LICENSE) [![build](https://img.shields.io/travis/rs/cors.svg?style=flat)](https://travis-ci.org/rs/cors)
CORS is a `net/http` handler implementing [Cross Origin Resource Sharing W3 specification](http://www.w3.org/TR/cors/) in Golang.
## Getting Started
After installing Go and setting up your [GOPATH](http://golang.org/doc/code.html#GOPATH), create your first `.go` file. We'll call it `server.go`.
```go
package main
import (
"net/http"
"github.com/rs/cors"
)
func main() {
h := http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
w.Header().Set("Content-Type", "application/json")
w.Write([]byte("{\"hello\": \"world\"}"))
})
// cors.Default() setup the middleware with default options being
// all origins accepted with simple methods (GET, POST). See
// documentation below for more options.
handler = cors.Default().Handler(h)
http.ListenAndServe(":8080", handler)
}
```
Install `cors`:
go get github.com/rs/cors
Then run your server:
go run server.go
The server now runs on `localhost:8080`:
$ curl -D - -H 'Origin: http://foo.com' http://localhost:8080/
HTTP/1.1 200 OK
Access-Control-Allow-Origin: foo.com
Content-Type: application/json
Date: Sat, 25 Oct 2014 03:43:57 GMT
Content-Length: 18
{"hello": "world"}
### More Examples
* `net/http`: [examples/nethttp/server.go](https://github.com/rs/cors/blob/master/examples/nethttp/server.go)
* [Goji](https://goji.io): [examples/goji/server.go](https://github.com/rs/cors/blob/master/examples/goji/server.go)
* [Martini](http://martini.codegangsta.io): [examples/martini/server.go](https://github.com/rs/cors/blob/master/examples/martini/server.go)
* [Negroni](https://github.com/codegangsta/negroni): [examples/negroni/server.go](https://github.com/rs/cors/blob/master/examples/negroni/server.go)
* [Alice](https://github.com/justinas/alice): [examples/alice/server.go](https://github.com/rs/cors/blob/master/examples/alice/server.go)
## Parameters
Parameters are passed to the middleware thru the `cors.New` method as follow:
```go
c := cors.New(cors.Options{
AllowedOrigins: []string{"http://foo.com"},
AllowCredentials: true,
})
// Insert the middleware
handler = c.Handler(handler)
```
* **AllowedOrigins** `[]string`: A list of origins a cross-domain request can be executed from. If the special `*` value is present in the list, all origins will be allowed. The default value is `*`.
* **AllowedMethods** `[]string`: A list of methods the client is allowed to use with cross-domain requests.
* **AllowedHeaders** `[]string`: A list of non simple headers the client is allowed to use with cross-domain requests. Default value is simple methods (`GET` and `POST`)
* **ExposedHeaders** `[]string`: Indicates which headers are safe to expose to the API of a CORS API specification
* **AllowCredentials** `bool`: Indicates whether the request can include user credentials like cookies, HTTP authentication or client side SSL certificates. The default is `false`.
* **MaxAge** `int`: Indicates how long (in seconds) the results of a preflight request can be cached. The default is `0` which stands for no max age.
See [API documentation](http://godoc.org/github.com/rs/cors) for more info.
