There are three ways as I see it. You can hook into the edit post method in one of two ways (json_insert_post or json_pre_insert_post), or you can extend the api with WP_JSON_CustomPostType or WP_JSON_Posts. Extending using posts, see class json media. Extending using custom post type see json page.

The downfall to using json_insert_post is that a new record (revision) of the post will be created and with a lot of comments, this may be undesirable. The downside to json_pre_insert_post is that you would have to return a WP Error object. That can be hacked by returning something like : return new WP_Error( 'json_comment_created', __('Your Comment ID ' . $commentID . 'Was Created.'), array( 'status' => 201));

http://codex.ww.wp.xz.cn/Function_Reference/wp_insert_comment

function put_a_comment($post, $data, $update){
 if($update){
  /*MAKE SURE COMMENT IS NOT SPAM, IS VALID, IS ESCAPED, WHATEVER*/
  $data = array(
     'comment_post_ID' => $post["ID"],
     {RESTOF_NEEDED_COMMENT_DATA}
  );
  $cmid = wp_insert_comment($data);
 }
}

add_action( 'json_insert_post', 'put_a_comment', 10, 3);

function put_a_comment_errr($true, $post, $data, $update){
 if($update){
  /*MAKE SURE COMMENT IS NOT SPAM, IS VALID, IS ESCAPED, WHATEVER*/
  $data = array(
     'comment_post_ID' => $post["ID"],
     {RESTOF_NEEDED_COMMENT_DATA}
  );
  $cmid = wp_insert_comment($data);
  return new WP_Error( 'json_comment_created', __('Your Comment ID ' . $cmid . 'Was Created.'), array( 'status' => 201));
 }
}

add_filter('json_pre_insert_post', 'put_a_comment_errr', 10, 4);

Extending is probably the best way to go. Then you can set your routes to '/posts/(?P<id>\d+)/comment' => array(array( array( $this, 'get_comments' ), WP_JSON_Server::EDITABLE | WP_JSON_Server::ACCEPT_JSON),),

Either way you do it, you have to make sure you send the json data. Something like “comment_author”:”blahblah”,”comment_body”:”blahblahblah” etc… then those params will be available in your data variable.

Ok, so in order to attach a featured image to a new post, you should first create the media attachment. You do that by either sending your post data to /media (I’m using upload from data, you can also send upload from file data – probably url with an @ at the beginning of the param -). If you are posting raw data, you have to allow unfiltered uploads capabilities in your wp_config file like so:

define( 'ALLOW_UNFILTERED_UPLOADS', true );

Then you have to collect the file data:

$filename = $_FILES['uploadedfile']['tmp_name'];
$finfo = new finfo(FILEINFO_MIME_TYPE);
$fmime = $finfo->file($filename);
$handle = fopen($filename, "r");
$fdata = fread($handle, filesize($filename))

;

Then pass the data via curl (if you’re using curl):

curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type:".$fmime, 'Content-Disposition: attachment; filename="' .$_FILES['uploadedfile']['name'] . '"', "Accept:application/json"...

and post that data:

curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $fdata);

If all is well, you should get a 201 created response status.

The returned data will include the new media attachment id:

$attachnfo = json_decode($result);
echo $attachnfo->ID;

Check for that status and if returned, go about creating a new post. To make sure the new post has the featured image set, make sure your params include a post_meta array with the meta key _thumbnail_id set to the returned ID of the successful attachment.
