In swagger-ui 3.2x, to manually set Authorization header based on values entered in the authorize popup for basic authentication, we can use below code.

const ui = SwaggerUIBundle({
        dom_id: '#swagger-ui',
        requestInterceptor: (req) => {
        if (!req.loadSpec) {
            var authorized = this.ui.authSelectors.authorized();
            //'Basic_Authentication' is security scheme key for basic authentication in the OpenApi file
            var basicAuth = getEntry(authorized, 'Basic_Authentication');
            if (basicAuth) {
                var basicAuthValue = getEntry(basicAuth, 'value');
                if (basicAuthValue) {
                    var username = getEntry(basicAuthValue, 'username');
                    var password = getEntry(basicAuthValue, 'password');
                    if (username && password) {
                        req.headers.Authorization = "Basic " + btoa(username + ":" + password); 
                    }
                }
            }
        }
        return req;
    }

//traverse through the object structure of swagger-ui authorized object to get value for an entryName
    function getEntry(complexObj, entryName) {
        if (complexObj && complexObj._root && complexObj._root.entries) {
            var objEntries = complexObj._root.entries;
            for (var t = 0; t < objEntries.length; t++) {
                var entryArray = objEntries[t];
                if (entryArray.length > 1) {
                    var name = entryArray[0];
                    if (name === entryName) {
                        return entryArray[1];
                    }
                }
            }
        }

        return null;
        }
