Valid arguments for the second parameter can be found in class-http.php in the header. There is not easy way to reference the list on the current version of this guide so I’m pasting the PHPDoc header here. Hopefully the docs site will expand the WP_Http page or find a way to reference the valid parameters through indirection while the robots build these pages.

Get a remote URL
/** @var array|WP_Error $response */ $response = wp_remote_get( 'http://www.example.com/index.html' ); if ( is_array( $response ) && ! is_wp_error( $response ) ) { $headers = $response['headers']; // array of http header lines $body = $response['body']; // use the content }Get a remote URL with special arguments
It would be cool to have a link to this somewhere on this page: http://wpsocket.com/wpref/function/wp_safe_remote_get/
replace
wp_get_http( $url, $filename )to get a remote file and write to the file system:Thank you @charlestonsw for pasting in the comments with the meaning of all the args, which lead me to this simple replacement.
When adding headers, each part of the header has to be a separate element like this:
not like cURL where you can use ‘Content-Type: application/json’
It’s better to execute JSON response like that to keep it managed.
$request = wp_remote_get($url, $options); return load_request($request); function load_request($response) { try { $json = json_decode( $response['body'] ); } catch ( Exception $ex ) { $json = null; } return $json; }Expand full source codeCollapse full source code
