### 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 [](https://godoc.org/github.com/rs/cors) [](https://raw.githubusercontent.com/rs/cors/master/LICENSE) [](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. |
||||
