 # 获取微信 ACCESS_TOKEN
 
+开发者授权知晓云后，知晓云在调用微信 API 时，会获取最新的 ACCESS_TOKEN ，这时如果开发者在自己的服务器上也刷新了 ACCESS_TOKEN 去调用微信的 API，会使知晓云的保存的 ACCESS_TOKEN 失效，会造成额外的 ACCESS_TOKEN 刷新，浪费 ACCESS_TOKEN 的生成次数。
+因此知晓云开放了获取知晓云保存的 ACCESS_TOKEN 的 API，开发者只管获取 ACCESS_TOKEN，而无需担心 ACCESS_TOKEN 过期的问题。
+
 `BaaS.wxAccessToken(signKey)`
