在AWS CLI负载均衡器中，我们可以使用lambda函数来处理OIDC令牌并对其进行缓存。以下是一个使用AWS Lambda和Redis进行OIDC缓存的示例代码：

首先，创建一个Redis实例并添加以下Lambda代码：

import redis
import requests
import json

TOKEN_ENDPOINT = ""
CLIENT_ID = ""
CLIENT_SECRET = ""

def get_access_token():
    payload = {'grant_type': 'client_credentials',
               'client_id': CLIENT_ID,
               'client_secret': CLIENT_SECRET}
    headers = {'Content-Type': 'application/json'}
    response = requests.post(TOKEN_ENDPOINT, headers=headers,
                             data=json.dumps(payload))
    return response.json()['access_token']


def handler(event, context):
    r = redis.Redis(host='', port=6379, db=0)
    token = r.get("oidc_token")
    if token is None:
        access_token = get_access_token()
        r.set("oidc_token", access_token, ex=3600)
        return access_token
    return token

然后，将此Lambda函数与负载均衡器集成，例如：

OIDCLambda:
  Type: "AWS::Lambda::Function"
  Properties:
    Role: 
    CodeUri: .
    Handler: oidc_lambda.handler
    Runtime: python3.8
    Environment:
      Variables:
        TOKEN_ENDPOINT: 
        CLIENT_ID: 
        CLIENT_SECRET: 
        REDIS_HOST: 

OIDCIntegration:
  Type: "AWS::ElasticLoadBalancingV2::Integration"
  Properties:
    IntegrationType: "Lambda"
    IntegrationUri: !Sub "arn:aws:lambda:${AWS::Region}:${AWS::AccountId}:function:OIDCLambda"
    IntegrationMethod: "POST"

最后，您可以在AWS CLI负载均衡器的目标组中使用由此Lambda函数返回的OIDC令牌。
