## OpenID Connect

OpenID Connectは、**OAuth2**をベースにした別の仕様です。

これはOAuth2を拡張したもので、OAuth2ではやや曖昧だった部分を明確にし、より相互運用性を高めようとしたものです。

例として、GoogleのログインはOpenID Connectを使用しています（これはOAuth2がベースになっています）。

しかし、FacebookのログインはOpenID Connectをサポートしていません。OAuth2を独自にアレンジしています。

### OpenID (「OpenID Connect」ではない)

また、「OpenID」という仕様もありました。それは、**OpenID Connect**と同じことを解決しようとしたものですが、OAuth2に基づいているわけではありませんでした。

from flask import Flask, request

boto3.set_stream_logger('boto3.resources', logging.DEBUG)

authorize_url = "http://localhost:8080/auth/realms/minio/protocol/openid-connect/auth"
token_url = "http://localhost:8080/auth/realms/minio/protocol/openid-connect/token"

# callback url specified when the application was defined
callback_uri = "http://localhost:8000/oauth2/callback"

# keycloak id and secret
client_id = 'account'

from fastapi.security.open_id_connect_url import OpenIdConnect
from fastapi.testclient import TestClient
from pydantic import BaseModel

app = FastAPI()

oid = OpenIdConnect(openIdConnectUrl="/openid", auto_error=False)


class User(BaseModel):
    username: str


def get_current_user(oauth_header: Optional[str] = Security(oid)):
    if oauth_header is None:
        return None

~ export MINIO_IDENTITY_OPENID_CONFIG_URL=http://127.0.0.1:5556/dex/.well-known/openid-configuration
~ minio server ~/test
```

### Run the `web-identity.go`

```
~ go run web-identity.go -cid example-app -csec ZXhhbXBsZS1hcHAtc2VjcmV0 \
     -config-ep http://127.0.0.1:5556/dex/.well-known/openid-configuration \
     -cscopes groups,openid,email,profile
```

```
~ mc admin policy create admin allaccess.json
```

		if !ok {
			return errors.New("STS JWT Token has `azp` claim invalid, `azp` must match configured OpenID Client ID")
		}
		if !azpValues.Contains(pCfg.ClientID) {
			return errors.New("STS JWT Token has `azp` claim invalid, `azp` must match configured OpenID Client ID")
		}
	}

	return nil
}

export MINIO_IDENTITY_OPENID_CLIENT_ID="843351d4-1080-11ea-aa20-271ecba3924a"
minio server /mnt/data
```

#### Casdoor

```
export MINIO_ROOT_USER=minio
export MINIO_ROOT_PASSWORD=minio123
export MINIO_IDENTITY_OPENID_CONFIG_URL=http://CASDOOR_ENDPOINT/.well-known/openid-configuration

	flag.StringVar(&configEndpoint, "config-ep",
		"http://localhost:8080/auth/realms/minio/.well-known/openid-configuration",
		"OpenID discovery document endpoint")
	flag.StringVar(&clientID, "cid", "", "Client ID")
	flag.StringVar(&clientSec, "csec", "", "Client Secret")
	flag.StringVar(&clientScopes, "cscopes", "openid", "Client Scopes")
	flag.IntVar(&port, "port", 8080, "Port")
}

### 5. Setup MinIO with OpenID configuration URL

MinIO server expects environment variable for OpenID configuration url as `MINIO_IDENTITY_OPENID_CONFIG_URL`, this environment variable takes a single entry.

```
export MINIO_IDENTITY_OPENID_CONFIG_URL=https://localhost:9443/oauth2/oidcdiscovery/.well-known/openid-configuration

	return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
		time.Sleep(delay)
		handler.ServeHTTP(w, r)
	})
}

// MockOpenIDDiscoveryServer is the in-memory openID discovery server.
type MockOpenIDDiscoveryServer struct {
	Port   int
	URL    string
	server *http.Server

	// How many times openIDCfg is called, use this number to verify cache takes effect.
	OpenIDHitNum uint64

from fastapi.security.open_id_connect_url import OpenIdConnect
from fastapi.testclient import TestClient
from pydantic import BaseModel

app = FastAPI()

oid = OpenIdConnect(openIdConnectUrl="/openid")


class User(BaseModel):
    username: str


def get_current_user(oauth_header: str = Security(oid)):
    user = User(username=oauth_header)
    return user


@app.get("/users/me")
