When using OpenIDConnect and the "authorization_code with PKCE" flow, swagger-ui will name the flow `authorization_code` rather than `authorizationCode`. [0] The old HTML document generated by fastapi only handled the latter spelling. This meant that trying to authenticate using the swagger UI would fail with: ``` auth errorError: Bad Request, error: invalid_request, description: Missing parameter: code ``` This commit updates the HTML used by fastapi for the `docs/oauth2-redirect` using the latest version published by swagger-ui [1] which brings in a fix for the bug described above. The rest of the changes relate to improving support for Chrome and Edge.

Update how the JavaScript
runfunction is invoked inoauth2-redirect.htmlto make it easier to allow in CSP.Description
The change moves away from using an inline event handler
<body onload="run()">to a programmatic event handler.Motivation and Context
We're embedding Swagger UI in an application that defines a content security policy — see an introduction on MDN if necessary.
One issue we're facing is that the
oauth2-redirect.htmlfile uses an inline event handler,<body onload="run()">, which is not supported by Chrome or Edge.The official Chrome docs mention that those should be rewritten using the
addEventListenermethod.They also recommend to use the
DOMContentLoadedevent on the document rather than theloadevent on the window, as the former "generally triggers more quickly".See https://developer.chrome.com/extensions/contentSecurityPolicy#:~:text=The%20inline%20event%20handler,more%20quickly
Because of this, we currently have to maintain a slightly modified copy of
oauth2-redirect.htmlfile to which we apply this change.We're hoping that you'll accept that change to be made upstream.
Related issue: #5720
How Has This Been Tested?
We've tested performing an OAuth 2 implicit flow with Chrome, the new Edge, and Firefox after allowing the specific hash of the contents of the
<script>tag in our content security policy.Screenshots (if appropriate):
