Firebase云函数中没有权限错误

我想用Passport.js+Firebase云函数实现一个松弛身份验证。但当我重定向URL时，出现了禁止的错误

错误：

您的客户端没有从该服务器获取URL/api/auth/slack？uid=XXXXXXXXXX&redirectTo=的权限

反应代码：

const slackAuthorizeURL = (uid) =>
  `https://us-central1-xxxxxxxxx.cloudfunctions.net/api/auth/slack?uid=${uid}&redirectTo=${window.location.href}`

<a href={slackAuthorizeURL}>Sign in with Slack</a>

我已经在谷歌云平台的api上设置了

alluser

到

Cloud Functions Admin

。

const passport = require('passport')

app.use(passport.initialize())
