中文的編碼有時候搭配 '/' 

會發生各種意想不到的錯誤

對於訪問的url要進行重新編碼處理

用encodeURL處理

// 雲函式入口檔案
const cloud = require('wx-server-sdk')
var request = require('request')
cloud.init();
exports.main = async (event, context) => {
  var isbn = event.isbn
  return new Promise((resolve, reject) => {
    request.get(encodeURI('https://api.douban.com/v2/book/search?q=' + event.q + '&start=' + event.start + '&count=30'), (error, response, body) => {
      if (error) {
        reject()
      } else {
        try {
          resolve(body)
        } catch (e) {
          reject()
        }
      }
    })
  })
}
