如下，我自己单独尝试连接mysql和腾讯暴露的接口连接都不行，求大神帮忙指导下。
另外，我将后端代码上传到腾讯云上面了，如何查看后端代码console.log的打印数据？

module.exports = async (ctx, next) => {

  if (ctx.state.$wxInfo.loginState === 1) {
  
    /*const { mysql: config } = require('../config');
    var knex = require('knex')({
      client: 'mysql',
      connection: {
        host: config.host,
        port: config.port,
        user: config.user,
        password: config.pass,
        database: config.db,
        charset: config.char,
        multipleStatements: true
      }
    });
    knex('question_sort').select('id').then(res => {
       console.log(res)
      ctx.state.data = res;
    })*/
    
    const { mysql } = require('../qcloud')
    mysql('question_sort').select('id').then(res => {
      ctx.state.data = res;
    })
    
  } else {
    ctx.state.code = -1
  }
}
