cube.js checkAuth 问题记录

默认cube.js 是基于jwt 进行认证的，当我们没有配置checkAuth 函数的时候，cube.js 的api server 会自动进行jwt 的解码
同时放到securityContext中，但是当我们自己配置了之后就不会自动处理securityContext了

解决方法

自己实现jwt 的解码，同时生成securityContext

• 参考demo

 

// Cube.js configuration options: https://cube.dev/docs/config

const {MaterializeDriver,MaterializeQuery} = require("@dalongrong/materialize-driver")

const {DremioDriver,DremioQuery} = require("@dalongrong/mydremio-driver")

const MyS3FileRepository = require("@dalongrong/cube-s3repository")

const jwt = require('jsonwebtoken');

 

module.exports = {

    dialectFactory: (dataSource) => {

        // need config  datasource  for multitenant env

        return DremioQuery

    },

    checkAuth: async (req, auth) => {

            // 注意异常处理

           var secret = process.env.CUBEJS_API_SECRET

           console.log("secret:",secret)

           const decoded = jwt.decode(auth, { complete: true });

           console.log(decoded)

           req.securityContext = decoded.payload;

    },

    queryTransformer: (query, { securityContext }) => {

        console.log(securityContext)

        return query;

      },

    dbType: ({ dataSource } = {}) => {

        return "mydremio"

    },

    driverFactory: ({ dataSource } = {}) => {

        return new DremioDriver({})

    },

    repositoryFactory: ({securityContext})=>{

        return new MyS3FileRepository.S3FileRepository({

            objectPrefix:"appdemo/"

        })

    }

};
