Issue

Hello!

Firstly, thanks for an awesome package! Such a huge help.

I got a question and I am hoping you can help me out on this. I am not quite sure but it seems that preauthorizeBasic and preauthorizeApiKey instance methods as documented in https://github.com/swagger-api/swagger-ui/blob/master/docs/usage/configuration.md are not yet supported by the package.

Are these options something that you plan to support in the future? If I overlooked it and that they're already supported, can you please provide an example on how I can pass them?

In swagger-ui-express, I am able to utilize the onComplete parameter to pass a function that invokes those instance methods as shown below:
{
tagsSorter: 'alpha',
onComplete: function () {
ui.preauthorizeBasic("basicAuth", "user", "pass");
ui.preauthorizeApiKey("apiKey", "apikey");
}
}

Thanks for the feedback in advance!

You should be able to pass the configuration through uiConfig.

Tried passing the following to uiConfig but it doesn't work:

uiConfig: {
  onComplete: function () {
     ui.preauthorizeBasic("basicAuth", "user", "pass");
     ui.preauthorizeApiKey("apiKey", "apikey");
  }
}

Am I passing it incorrectly?

I ended up adding some custom code to achieve this in swagger-initializer.js though as a workaround.

swagger-ui-express is dynamic generate the JavaScript where as we statically provide the JavaScript.

I don't think .toString a function would be good and it somehow prone to error since people may think that variable will work inside the function.

The issue is that the uiConfig is serialized to json and supplied by a rest-call. And functions cant be serialized.

So we have to find a way to provide the functions in a javascript file or somehow differently...
