Node-wechat-sign NPM

Wechat-Sign

Make it easier to get wechat access_token, jsapi_ticket and sign url

Installation

npm install node-wechat-sign

Usage

  import Wechat from 'node-wechat-sign'

  const wechat = new Wechat(config)  // You should instantiate it out of your method if you need to share the cache among methods

  const access_token = await wechat.getAccessToken()
  const jsapi_ticket = await wechat.getTicket()
  const signature = await wechat.sign(url)

Here use memory to cache the access_token and jsapi_ticket. To refresh the cached access_token or jsapi_ticket, pass in a refresh parameter with true value:

  const refresh = true
  const access_token = await wechat.getAccessToken(refresh)
  const jsapi_ticket = await wechat.getTicket(refresh)
