Parses **Link** headers used for pagination, as defined in [RFC 5988](https://tools.ietf.org/html/rfc5988).
This package was originally based on <https://github.com/swhite24/link>, but **Parse** takes a `string` instead of `*http.Request` in this version.
It also has the convenience functions **ParseHeader**, **ParseRequest** and **ParseResponse**.
## Installation
go get -u github.com/peterhellberg/link
## Exported functions
- [Parse(s string) Group](https://godoc.org/github.com/peterhellberg/link#Parse)
- [ParseHeader(h http.Header) Group](https://godoc.org/github.com/peterhellberg/link#ParseHeader)
- [ParseRequest(req \*http.Request) Group](https://godoc.org/github.com/peterhellberg/link#ParseRequest)
- [ParseResponse(resp \*http.Response) Group](https://godoc.org/github.com/peterhellberg/link#ParseResponse)
## Usage
```go
package main
import (
"fmt"
"net/http"
"github.com/peterhellberg/link"
)
func main() {
for _, l := range link.Parse(`<https://example.com/?page=2>; rel="next"; foo="bar"`) {
fmt.Printf("URI: %q, Rel: %q, Extra: %+v\n", l.URI, l.Rel, l.Extra)
// URI: "https://example.com/?page=2", Rel: "next", Extra: map[foo:bar]
}
if resp, err := http.Get("https://api.github.com/search/code?q=Println+user:golang"); err == nil {
for _, l := range link.ParseResponse(resp) {
fmt.Printf("URI: %q, Rel: %q, Extra: %+v\n", l.URI, l.Rel, l.Extra)
// URI: "https://api.github.com/search/code?q=Println+user%3Agolang&page=2", Rel: "next", Extra: map[]
// URI: "https://api.github.com/search/code?q=Println+user%3Agolang&page=34", Rel: "last", Extra: map[]
}
}
}
```
