/** * Thin jQuery.ajax wrapper for WP REST API requests. * * Currently only applies to requests that do not use the `wp-api.js` Backbone * client library, though this may change. Serves several purposes: * * - Allows overriding these requests as needed by customized WP installations. * - Sends the REST API nonce as a request header. * - Allows specifying only an endpoint namespace/path instead of a full URL. * * @since 4.9.0 * @since 5.6.0 Added overriding of the "PUT" and "DELETE" methods with "POST". * Added an "application/json" Accept header to all requests. * @output wp-includes/js/api-request.js */ ( function( $ ) { var wpApiSettings = window.wpApiSettings; function apiRequest( options ) { options = apiRequest.buildAjaxOptions( options ); return apiRequest.transport( options ); } apiRequest.buildAjaxOptions = function( options ) { var url = options.url; var path = options.path; var method = options.method; var namespaceTrimmed, endpointTrimmed, apiRoot; var headers, addNonceHeader, addAcceptHeader, headerName; if ( typeof options.namespace === 'string' && typeof options.endpoint === 'string' ) { namespaceTrimmed = options.namespace.replace( /^\/|\/$/g, '' ); endpointTrimmed = options.endpoint.replace( /^\//, '' ); if ( endpointTrimmed ) { path = namespaceTrimmed + '/' + endpointTrimmed; } else { path = namespaceTrimmed; } } if ( typeof path === 'string' ) { apiRoot = wpApiSettings.root; path = path.replace( /^\//, '' ); // API root may already include query parameter prefix // if site is configured to use plain permalinks. if ( 'string' === typeof apiRoot && -1 !== apiRoot.indexOf( '?' ) ) { path = path.replace( '?', '&' ); } url = apiRoot + path; } // If ?_wpnonce=... is present, no need to add a nonce header. addNonceHeader = !
