解码并设置Jwt有效载荷以请求参数

我们正在将Express-gateway用于我们的微服务。我们已经使用Jwt设置了身份验证。我们要验证jwt并解码有效负载并将其设置为req params

这是我们的gateway.config.yml文件

http:
  port: 8080
admin:
  port: 9876
  host: localhost
apiEndpoints:
  user:
    host: localhost
    paths: "/v1/users"
  product:
    host: localhost
    paths: "/v1/products"
serviceEndpoints:
  user:
    url: http://localhost:3001
  product:
    url: http://localhost:3000
policies:
- basic-auth
- key-auth
- cors
- expression
- log
- oauth2
- proxy
- rate-limit
- jwt
pipelines:
- name: default-1
  apiEndpoints:
  - user
  policies:
  - jwt:
    - action:
        secretOrPublicKey: privatekey
        checkCredentialExistence: 'false'
  - proxy:
    - action:
        serviceEndpoint: user
- name: default-2
  apiEndpoints:
  - product
  policies:
  - jwt:
    - action:
        secretOrPublicKey: privatekey
        checkCredentialExistence: 'false'
  - proxy:
    - action:
        serviceEndpoint: product

我的Jwt有效负载令牌看起来像

{
  "org": "1234567890",
  "siteID": "343434343",
  "expiry": "600"
}

在解码并验证了jwt签名后，网关应将有效负载信息设置为req为

req.org = payload.org
req.siteId = payload.siteId

并将其传递给我们的基础微服务。这该怎么做。我是否应该在gateway.config.yml文件中设置更多参数。请指教。谢谢
