const {mysql} = require('../qcloud')
module.exports = async (ctx) => {
const {bookId} = ctx.request.query
const detail = await mysql('books')
.select('books.*', 'cSessionInfo.user_info')
.join('cSessionInfo', 'books.open_id', 'cSessionInfo.open_id')
.where('id', bookId)
.first()
哪里的文档可以查看select(),join(),where(),first()这些相关函数
