Swagger UI with OAuth Authorization Code Flow (PKCE)

This repository demonstrates how to customize Swagger UI to support the OAuth Authorization Code flow with PKCE.

Customizations

Enable PKCE:

Set usePkceWithAuthorizationCodeGrant to true in the ui.initOAuth call in the index.html file.

Request Interceptor:

Add a requestInterceptor function to remove the X-Requested-With HTTP request header. This prevents the CORS token request from being transformed into a complex request, which would trigger an OPTIONS preflight.

Usage

Follow these steps to run the example:

1. Clone the repository:

   git clone git@github.com:curityio/swagger-ui-auth-code-pkce-flow.git

2. Navigate to the project directory:

   cd swagger-ui-auth-code-pkce-flow

3. Start the Swagger UI container:

   docker run -p 8080:8080 \
     -e BASE_URL=/swagger \
     -e API_URL=/swagger/swagger.yaml \
     -v $(pwd)/swagger.yaml:/usr/share/nginx/html/swagger.yaml \
     -v $(pwd)/index.html:/usr/share/nginx/html/index.html \
     swaggerapi/swagger-ui

4. Open your browser and go to: http://localhost:8080/swagger

5. Click the Authorize button to initiate the OAuth Authorization Code flow with PKCE.

NOTE: Ensure that http://localhost:8080/swagger/oauth2-redirect.html is added as a redirect URI in your OAuth client configuration
