Firebase 函数：参数"data"的值不是有效的 Firestore 文档

Question

我正试图用下面的代码来学习oAuth2的消防船教程。

所有功能都已正确初始化，但当我试图通过twitter授权应用程序时，出现了此错误消息。错误消息如下。

⚠函数：错误：参数"的值；数据"；不是有效的Firestore文档。不能使用"；未定义的"；作为Firestore值(在字段"accessToken"中找到(。如果要忽略未定义的值，请启用ignoreUndefinedProperties。

代码如下：

const functions = require('firebase-functions')
const admin = require('firebase-admin')
admin.initializeApp()
// Database reference
const dbRef = admin.firestore().doc('tokens/demo')
const TwitterApi = require('twitter-api-v2').default
const twitterClient = new TwitterApi({
clientId: 'aabbcc',
clientSecret: 'aabbcc',
})
const callbackURL =
'http://127.0.0.1:5001/primussoft-74a49/us-central1/callback'
// STEP 1 - Auth URL
exports.auth = functions.https.onRequest(async (request, response) => {
const { url, codeVerifier, state } = twitterClient.generateOAuth2AuthLink(
callbackURL,
{ scope: ['tweet.read', 'tweet.write', 'users.read', 'offline.access'] }
)
// store verifier
await dbRef.set({ codeVerifier, state })
response.redirect(url)
})
// STEP 2 - Verify callback code, store access_token
exports.callback = functions.https.onRequest(async (request, response) => {
const { state, code } = request.query
const dbSnapshot = await dbRef.get()
const { codeVerifier, state: storedState } = dbSnapshot.data()
if (state !== storedState) {
return response.status(400).send('Stored tokens do not match!')
}
const {
client: loggedClient,
accessToken,
refreshToken,
} = twitterClient.loginWithOAuth2({
code,
codeVerifier,
redirectUri: callbackURL,
})
await dbRef.set({ accessToken, refreshToken })
const { data } = loggedClient.v2.me() // start using the client if you want
response.send(data)
})
// STEP 3 - Refresh tokens and post tweets
exports.tweet = functions.https.onRequest(async (request, response) => {
const { refreshToken } = dbRef.get().data()
const {
client: refreshedClient,
accessToken,
refreshToken: newRefreshToken,
} = twitterClient.refreshOAuth2Token(refreshToken)
await dbRef.set({ accessToken, refreshToken: newRefreshToken })
//   const { data } = await refreshedClient.v2.tweet(
//     nextTweet.data.choices[0].text
//   )
const { dataone } = { id: 'testid', text: 'a tweet from me' }
response.send(dataone)
})
exports.tweet = functions.https.onRequest((request, response) => {})

如有任何帮助，我们将不胜感激。

Answer 1

refreshOAuth2Token方法也返回一个promise。尝试添加await，如下所示：

const {
client: refreshedClient,
accessToken,
refreshToken: newRefreshToken,
} = await twitterClient.refreshOAuth2Token(refreshToken)
