WP_Remote_Get Not working

I have a plugin which uses wp_remote_get() and it's not working on my nginx server so I decided to test this.

I created a file called test.php and inserted:

?php $response = wp_remote_get( 'http://www.domain.com/mytest.php' );

print $response ['body']; ?

When I run this file I am getting error:

2017/02/04 16:22:31 [error] 16573#16573: *461100 FastCGI sent in stderr:
…

 "PHP message: PHP Fatal error:  Uncaught Error: Call to undefined function
 wp_remote_get() in /var/www/html/wp-content/themes/x-child/test.php:1

I cannot tell why this would be undefined function, given that its part of wordpress core?

The very concept of HTTP API is to make sure transport will be done. It basically uses 5 different transport methods and it chooses the best one according to your server config. So it's unlikely a compatibility issue with wp_remote_get() and your server.

Plus if WP is not loaded, adding an action won't help, it will fail the same with undefined function error but this time on add_action.

So basically you're missing WordPress, for test purpose you could do this (assuming your file is at the root of WP installation ) :

<?php 
require_once( 'wp-load.php' );
$response = wp_remote_get( 'http://www.domain.com/mytest.php' );
print $response ['body']; ?>

Are you trying to access your test.php file directly? If so, then WordPress won't be loaded, so wp_remote_get() won't work.

To use wp_remote_get you need to make sure WordPress is loaded. Try hooking into wp_loaded:

add_action( 'wp_loaded', function() {
  $response = wp_remote_get( 'https://example.com/' );
  print $response[ 'body' ];
} );

There's a chance your server is configured in such a way that the methods used by wp_remote_get are not available to WordPress. If that's the case, make sure curl or wget is installed on the server.
