Enable CORS on JSON API Wordpress

Question

I have this wordpress site with a plugin called JSON API. This plugin provides a JSON format for the content that is in the wordpress. I was able to enable CORS on the wordp

Answer 1

Ok I finally figured out an easy way...

You just have to add:

     <? header("Access-Control-Allow-Origin: *"); ?>

On the file api.php, this file is located in wp-content/plugins/json-api/singletons/api.php

I hope it helps more people with the same problem!

Answer 2

In wordpress goto plugins > JSON API > Edit

From the right hand file selection select

json-api/singletons/api.php

You will need to add the following line

header("Access-Control-Allow-Origin: *");

Your code should look similar to this once done. Adding this line anywhere else might not work as expected.

<?php
header("Access-Control-Allow-Origin: *"); 
class JSON_API {

  function __construct() {
    $this->query = new JSON_API_Query();
    $this->introspector = new JSON_API_Introspector();
    $this->response = new JSON_API_Response();
    add_action('template_redirect', array(&$this, 'template_redirect'));
    add_action('admin_menu', array(&$this, 'admin_menu'));
    add_action('update_option_json_api_base', array(&$this, 'flush_rewrite_rules'));
    add_action('pre_update_option_json_api_controllers', array(&$this, 'update_controllers'));
  }

  function template_redirect() {

In WordPress project go to following file and do like this:

In wp-includes/rest-api.php change:

header( 'Access-Control-Allow-Origin: ' . $origin );

to:

header( 'Access-Control-Allow-Origin: *' );

In wp-includes/http.php change:

header( 'Access-Control-Allow-Origin: ' . $origin );

to:

header( 'Access-Control-Allow-Origin: *' );

Answer 4

Now that REST API is merged with core, we can use the rest_api_init action.

add_action( 'rest_api_init', function()
{
    header( "Access-Control-Allow-Origin: *" );
} );
