## 説明

Adds a JSON Feed to your WordPress site by adding `/feed/json` to any URL.

The JSON Feed format is a pragmatic syndication format, like RSS and Atom, but with
one big difference: it’s JSON instead of XML. Learn more at [jsonfeed.org](http://jsonfeed.org/).

## インストール

 1. Upload the plugin files to the `/wp-content/plugins/jsonfeed` directory, or install
    the plugin through the WordPress plugins screen directly.
 2. Activate the plugin through the ‘Plugins’ screen in WordPress

## FAQ

### What is JSONFeed?

JSON Feed, a format similar to RSS and Atom but in JSON. JSON has become the developers’
choice for APIs, and that developers will often go out of their way to avoid XML.

JSON is simpler to read and write, and it’s less prone to bugs.

### Can I add other fields to the feed?

Yes you can! There is a filter, `json_feed_item`, that allows you to modify the 
items in the feed just before they’re inserted into the feed itself. For example,
if you want to add a link to a post author’s archive page to the respective item
in the feed, you can use the following code:

    ```
    `
    ```

function wp_custom_json_feed_fields( $feed_item, $post ){
 $feed_item[‘author’][‘
archive_link’] = get_author_posts_url( $post->post_author );

    ```
    return $feed_item;
    ```

}
 add_filter( ‘json_feed_item’, ‘wp_custom_json_feed_fields’, 10, 2); `

### Can I write information to my posts?

This is a syndication format, which means it only represents your posts and comments
as feed elements. This is read only, similar to RSS or Atom. It is not an API.

No bells and whistles, no unexpected behavior, just a jsonfeed for your blog.

Works beautifully! All I had to do was install the plugin and I could immediately
see my JSON feed at /feed/json.

The plugin does exactly what says on the tin. There are no settings, no Pro version,
no ads and no other bells and whistles. Recommended!

says on the tin.
