错误：由文件index.js定义的Node.js模块应该导出名为xxxx的函数

Question

你好，开发社区。我正在尝试调试firebase函数，并尝试使用一些教程，但没有成功...

我尝试过（https://medium.com/@mwebler/debugging-firebase-functions-with-vs-code-3afab528bb36）（https://medium.com/@david_mccoy/build-and-debug-firebase-functions-in-vscode-73efb76166cf）

我的目的是与Google联系。

functions / index.js

const { google } = require('googleapis');
const oauthUserCredential = require('./oauthUserCredential.json')
const OAuth2 = google.auth.OAuth2

const key = require('./serviceAccountKey.json')
const jwt = new google.auth.JWT(key.client_email, null, key.private_key, 'https://www.googleapis.com/auth/contacts')

exports.getGoogleContacts = functions.https.onCall(async (data, context) => {

  const requestingUser = data.requestingUser
  console.log('getGoogleContacts-requestingUser', requestingUser)


  const oauth2Client = new google.auth.OAuth2(
    'client_id',
    'client_secret',
    'http://localhost:5000/xxx-xxx/us-central1/OAuthCallbackUrl'
  );


  const contacts = google.people({
    version: 'v1',
    auth: oauth2Client,
  });

  console.log('contacts ?', contacts)

    (async () => {
      const { data: groups } = await contacts.people.get({
        resourceName: 'contactGroups',
      });
      console.log('Contact Groups:\n', groups);

    })()


  jwt.authorize((err, response) => {
    console.log('inside authorize')
    if (err) {
      console.error(err);
      response.end();
      return;
    }

    // Make an authorized request to list contacts.
    contacts.people.connections.list({
      auth: authClient,
      resourceName: 'people/me'
    }, function (err, resp) {
      if (err) {
        console.error(err);
        response.end();
        return;
      }

      console.log("Success");
      console.log(resp);
      response.send(resp);
    });

  });

  // this is another approach I´ve tried, but it´s also not working

  const oAuth2Client = new OAuth2(
    oauthUserCredential.web.client_id,
    oauthUserCredential.web.client_secret,
    oauthUserCredential.web.redirect_uris,
)

oAuth2Client.setCredentials({
    refresh_token: oauthUserCredential.refresh_token
})
return new Promise((resolve, reject) => {
    console.log('[INSIDE PEOPLE CONNECTIONS]')
    contacts.people.connections.list({
        auth: oauth2Client //authetication object generated in step-3
    }, function (err, response) {
        if (err) {
            console.log('contacts.people.connections error')
            console.log(err)
            reject(new Error(err))
        } else if (response) {
            console.log('contacts.people.connections response')
            console.log(response)
            resolve(response)
        }
    });
})
    .then(result => { return { found: result } })
    .catch(err => { return { error: err } })


})

我尝试了几种不同的方法并遵循了不同的教程（Using Google People API with Cloud Functions for Firebase）（https://flaviocopes.com/google-api-authentication/）（https://medium.com/@smccartney09/integrating-firebase-cloud-functions-with-google-calendar-api-9a5ac042e869）（https://cloud.google.com/community/tutorials/cloud-functions-oauth-gmail）

但是他们都没有清楚显示我如何获取我的联系人列表。通过遵循本教程，我可以使用客户端代码（https://labs.magnet.me/nerds/2015/05/11/importing-google-contacts-with-javascript.html）但是我认为将暴露在客户端的client_id，client_secret和apiKey放在安全位置会是一个安全问题...

我也在提交教程请求，以使其非常清楚如何使用Firebase函数从Google帐户获取联系人列表。

您收到的错误是因为云函数无法找到名为xxxx的函数来执行，因为您尚未在index.js文件中定义任何名为xxxx的函数。

您的云函数要执行的名称，根据错误消息是xxxx，但是您在index.js中调用的函数是getGoogleContacts。请确保这些名称相同，例如将getGoogleContacts更改为xxxx或将要执行的函数更改为getGoogleContacts
