Feeds provides a simple, generic Feed interface with a generic Item object as well as RSS, Atom and JSON Feed specific RssFeed, AtomFeed and JSONFeed objects which allow access to all of each spec's defined elements.
|
||
|
|
|
||
|
|
Examples
|
||
|
|
|
||
|
|
Create a Feed and some Items in that feed using the generic interfaces:
|
||
|
|
|
||
|
|
import (
|
||
|
|
"time"
|
||
|
|
. "github.com/gorilla/feeds"
|
||
|
|
)
|
||
|
|
|
||
|
|
now = time.Now()
|
||
|
|
|
||
|
|
feed := &Feed{
|
||
|
|
Title: "jmoiron.net blog",

|

feed.Items = []*Item{
|

&Item{

|

|
|
|

From here, you can output Atom, RSS, or JSON Feed versions of this feed easily
|
||
|
|
|
||
|
|
atom, err := feed.ToAtom()
|
||
|
|
rss, err := feed.ToRss()
|
||
|
|
json, err := feed.ToJSON()
|
||
|
|
|
||
|
|
You can also get access to the underlying objects that feeds uses to export its XML
|
||
|
|
|
||
|
|
atomFeed := (&Atom{Feed: feed}).AtomFeed()
|
||
|
|
rssFeed := (&Rss{Feed: feed}).RssFeed()
|
||
|
|
jsonFeed := (&JSON{Feed: feed}).JSONFeed()
|
||
|
|
|
||
|
|
From here, you can modify or add each syndication's specific fields before outputting
|
||
|
|
|
||
|
|
atomFeed.Subtitle = "plays the blues"
|
||
|
|
atom, err := ToXML(atomFeed)
|
||
|
|
rssFeed.Generator = "gorilla/feeds v1.0 (github.com/gorilla/feeds)"
|
||
|
|
rss, err := ToXML(rssFeed)
|
||
|
|
jsonFeed.NextUrl = "https://www.example.com/feed.json?page=2"
|
||
|
|
json, err := jsonFeed.ToJSON()
|
||
|
