Firebase 电子邮件功能找不到用户

Question

我的网站上有一个联系表单，在发送点击提交后，它会运行一个 firebase 函数来执行请求。我突然遇到的问题是以下错误（取自 firebase 日志）

Error: There is no user record corresponding to the provided identifier.
    at FirebaseAuthError.FirebaseError [as constructor] (/workspace/node_modules/firebase-admin/lib/utils/error.js:42:28)
    at FirebaseAuthError.PrefixedFirebaseError [as constructor] (/workspace/node_modules/firebase-admin/lib/utils/error.js:88:28)
    at new FirebaseAuthError (/workspace/node_modules/firebase-admin/lib/utils/error.js:147:16)
    at /workspace/node_modules/firebase-admin/lib/auth/auth-api-request.js:513:15
    at /workspace/node_modules/firebase-admin/lib/auth/auth-api-request.js:1347:13
    at process._tickCallback (internal/process/next_tick.js:68:7)

负责发送的函数如下：

    sendRequest() {
      this.loading = true
      return new Promise(resolve => {
        const newUrl = `https://us-central1-easymediakit.cloudfunctions.net/contactForm?name=${
          this.form.name
        }&email=${this.form.email}&message=${encodeURI(
          this.form.message
        )}&uid=${this.uid}`
        fetch(`${newUrl}`, {
          withCredentials: true,
          headers: {
            'Content-Type': 'application/json'
          }
        })
          .then(() => {})
          .then(async response => {
            this.loading = false
            this.success = 'Your email has been sent.'
            resolve(response)
          })
      }).catch(error => {
        this.loading = false
        console.log('Send error', error)
      })
    }

它工作正常，我没有对处理电子邮件发送的函数进行任何更改，所以我不确定问题出在哪里，非常感谢任何指导。

更新：

在 index.js 中

const contactFormModule = require('./email/email-contact-form')

exports.contactForm = functions.https.onRequest((req, res) => {
  return contactFormModule.handler(req, res)

联系表格：

const cors = require('cors')({ origin: true })
const domain = 'mg.epkbuilder.com'
const apiKey = 'f27b2755b05f3a366542ea538a00c6a2-d32d817f-dec22e2e'
const mailgun = require('mailgun-js')({ apiKey, domain })
const admin = require('firebase-admin')
const MailComposer = require('nodemailer/lib/mail-composer')

exports.handler = (req, res) => {
  cors(req, res, async () => {
    const uid = req.query.uid
    const name = req.query.name
    const email = req.query.email
    const message = req.query.message

    console.log('uid', uid)

    console.log('message', `${message}`)

    const user = await admin.auth().getUser(uid)

    console.log('user', user)

    const mailOptions = {
      from: `${name} noreply@easymediakit.io`,
      replyTo: `${name} ${email}`,
      to: user.email,
      subject: `Direct message from ${name}`,
      text: `${message}`
    }

    let mail = new MailComposer(mailOptions).compile()

    console.log('mail', mail)

    return mail.build((error, message) => {
      if (error) {
        console.log('Email unsuccessful', error)
        res.status(400).send(error)
      }
      const dataToSend = {
        to: user.email,
        message: message.toString('ascii')
      }
      return mailgun.messages().sendMime(dataToSend, sendError => {
        if (sendError) {
          console.log('Email unsuccessful', error)
          res.status(400).send(error)
        }
        return res.send('Email successfully sent!')
      })
    })
  })
}

错误似乎来自这一行：

const user = await admin.auth().getUser(uid)

该错误表明对于您指定的 uid 值，Firebase 身份验证中不存在任何用户。您可能需要在客户端代码中仔细检查 )}&uid=${this.uid} 中的 this.uid 值。
