为啥请求生成二维码，一直返回"errcode":-1？

【错误信息】：错误代码：-1, 错误信息：系统繁忙，此时请开发者稍候再试，微信原始报文：{“errcode”:-1,“errmsg”:“system error rid: 619f4c2e-2706fc5b-74dca28f”}

最后还微信服务端异常，超出重试次数

{"dns":[{"ip":"101.132.172.219","real_operator":"UNICOM"}],"ping":[{"ip":"101.132.172.219","from_operator":"UNICOM","package_loss":"100%","time":""}]}

求求你们快来个人修复一下吧
