Hello everyone, i want to know how to imbed access token to webview to authen through apisix and keycloak. Please help me if you know.
Regardless of the method you have tried:

  1. Cookie
  2. Header Authorization
  3. Param Encode in URL.

This is my setting in apisix:

      "_meta": {
        "disable": false
      },

      "access_token_expires_leeway": 0,
      "cache_ttl_seconds": 60,
      "client_id": "object_removal",
      "client_secret": "ruo5IxxF0v",

      "refresh_token_expires_leeway": 0,
      "ssl_verify": true,
      "timeout": 3000,
      "token_endpoint": "http://host.docker.internal:8080/realms/apisix_test_realm/protocol/openid-connect/token"
    },
    "cors": {
      "allow_headers": "Authorization, Content-Type",
      "allow_methods": "GET, POST, OPTIONS",
      "allow_origins": "*"
    }
  },
  "upstream": {
    "nodes": [
      {
        "host": "host.docker.internal",
        "port": 8501,
        "weight": 1
      }
    ],
    "timeout": {
      "connect": 6,
      "send": 6,
      "read": 6
    },
    "type": "roundrobin",
    "scheme": "http",
    "pass_host": "pass",
    "keepalive_pool": {
      "idle_timeout": 60,
      "requests": 1000,
      "size": 320
    }
  },
  "status": 1
}

Expect: access http://127.0.0.1:9080/service

Maybe I got something wrong, but typically, WebView-like approaches are used to perform front-channel authentication. Then, in the back-channel part of the authorization code flow, you exchange the authorization code (retrieved via redirect) for a token, store the token in the keychain, and reuse it for interacting with your backends. The WebView, in this case, just operates with cookies (sso cookies) that could be useful for cookies based SSO authentication between mobile apps that reuse the same webview
