How to use Basic auth in swagger ui v.3.0

Question

in swagger ui 2.0 it was code

var basicAuth = new SwaggerClient.PasswordAuthorization("basicAuth", username, password);
window.swaggerUi.api.clientAuthorizations.add("basicAuth", basicAuth);

Can somebody provide code for version swagger ui 3.0?

Thanks.

Edit. i`m trying to do something like this - Adding Basic Authorization for Swagger-UI

I`m using Swagger on server with Basic auth. SO i cant init library.

  const ui = SwaggerUIBundle({
url: "http://petstore.swagger.io/v2/swagger.json",
dom_id: '#swagger-ui',
presets: [
  SwaggerUIBundle.presets.apis,
  // yay ES6 modules ↘
  Array.isArray(SwaggerUIStandalonePreset) ? SwaggerUIStandalonePreset : SwaggerUIStandalonePreset.default
],
plugins: [
  SwaggerUIBundle.plugins.DownloadUrl
],
layout: "StandaloneLayout"
  })

window.ui = ui

without basic auth everything works fine.

basic auth enabled - http://prntscr.com/enxee4

In Swagger UI 3.x, fetching specs (.yaml/.json files) protected with Basic auth / API keys is supported in ver. 3.3.2 and later. In your Swagger UI initialization code, define a requestinterceptor that attaches auth headers to the spec fetch request:

<!-- index.html -->

const ui = SwaggerUIBundle({
  url: "http://petstore.swagger.io/v2/swagger.json",

  requestInterceptor: (req) => {
    if (req.loadSpec) {
        // Fetch the spec using Basic auth, replace "user" and "password" with yours
        req.headers.Authorization = 'Basic ' + btoa('user:password');

        // or API key
        // req.headers.MyApiKey = 'abcde12345';

        // or bearer token
        // req.headers.Authorization = 'Bearer abcde12345';
    }
    return req;
  },
  ...
})

I build an index.html with a simple form to fill user credentials to get a session id. Then redirect to swagger.html, for instance, and make some changes.

Before window.onload:

var orgFetch;

window.setExtraHeader = function(sessionId) {
    var system = window.ui.getSystem();

    if(!system) return;

    if(!orgFetch) {
        orgFetch = system.fn.fetch;
    }

    system.fn.fetch = function(obj) {
        if(!obj) return;

        if(!obj.headers) {
            obj.headers = {};
        }

        obj.headers['sessionId'] = sessionId;

        return orgFetch(obj)
            .then(function(fetchRes) {
                return fetchRes;
            });
    }

    system.specActions.download();
}

and then:

window.ui = ui;
window.setExtraHeader(localStorage.getItem("sessionId"));

Hope this helps.
