无法读取未定义 express js 的属性“已安装”

Question

我无法使用 Express js 或 google sheet api 找到此问题的示例。我正在运行一个接收 POST 请求的快速应用程序，然后将其传递给使用 oAuth2 的函数，然后将数据作为附加行发送到谷歌表

当我调用 updateSheet() 时出现以下错误

UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'installed' of undefined
    at resolve (C:\Users\luther\Desktop\Pantree\index.js:50:69)
    at new Promise (<anonymous>)
    at authorize (C:\Users\luther\Desktop\Pantree\index.js:49:10)
    at updateSheet (C:\Users\luther\Desktop\Pantree\index.js:91:28)

我不知道为什么在发布时会出现此错误，因为该错误是在我的 authorize() 调用中引发的，该调用在从工作表中获取初始数据时完美运行。

我已更新 google sheet API 范围以允许读取和写入，如下所示。 我在我的资源对象中使用虚拟数据来排除正文解析器的问题，所以目前我从我的帖子请求中所做的只是调用 updateSheet() 没有参数

const SCOPES = ['https://www.googleapis.com/auth/spreadsheets'];
const TOKEN_PATH = 'token.json';


// Load client secrets from a local file.
fs.readFile('client_secret.json', (err, content) => {
  if (err) return console.log('Error loading client secret file:', err);
  // Authorize a client with credentials, then call the Google Sheets API.
  authorize(JSON.parse(content), grabSheetData);
});

/**
 * Create an OAuth2 client with the given credentials, and then execute the
 * given callback function.
 * @param {Object} credentials The authorization client credentials.
 * @param {function} callback The callback to call with the authorized client.
 */
function authorize(credentials) {
  return new Promise(resolve => {  // Added
    const { client_secret, client_id, redirect_uris } = credentials.installed;
    const oAuth2Client = new google.auth.OAuth2(client_id, client_secret, redirect_uris[0]);

    // Check if we have previously stored a token.
    fs.readFile(TOKEN_PATH, (err, token) => {
      if (err) return getNewToken(oAuth2Client, e => resolve(e)); 
      oAuth2Client.setCredentials(JSON.parse(token));
      resolve(oAuth2Client); 
    });
  });
}


/* GET SHEET DATA */
async function grabSheetData () {
  var data = {
    payload: ''
  }
  const authClient = await authorize(creds);  
  const request = {
    spreadsheetId: 'xxxxxxxxxxxxxxxxxxxx', 
    range: 'A1:C',
    valueRenderOption: "FORMATTED_VALUE",  
    dateTimeRenderOption: "SERIAL_NUMBER",  
    auth: authClient, 
  }

  try {
    const response = (await sheets.spreadsheets.values.get(request)).data;

    console.log(JSON.stringify(response, null, 2));
    data.payload=response
  } catch (err) {
    console.error(err);
  }
  return data
};


/* WRITE TO SHEET */
async function updateSheet () {
  const authClient = await authorize();
  const request = {
    spreadsheetId: 'xxxxxxxxxxxxxxxx', 
    range: 'A7:C7', 
    valueInputOption: 'RAW', 
    insertDataOption: 'INSERT_ROWS',
    resource: {
      item: 'dummyname',
      dateLogged:'dummydate',
      expires:'dummy expire'
    },

    auth: authClient,
  };

  try {
    const response = (await sheets.spreadsheets.values.append(request)).data;

    console.log(JSON.stringify(response, null, 2));
  } catch (err) {
    console.error(err);
  }
}

我的 app.post

app.post('/api/updateSheet', (req,res)=>{
    updateSheet()
});

我忘记在 updateSheets() 调用中将凭据传递给我的授权调用

async function updateSheet () {
  const authClient = await authorize(creds); //PASS CREDS HERE
  const request = {
    spreadsheetId: '1VTiTgPvMvLlOVBhBfoMGrshfMMJJMMzoA6GesheWMPg', 
    range: 'A7:C7', 
    valueInputOption: 'RAW', 
    insertDataOption: 'INSERT_ROWS',
    resource: {
      item: 'dummyname',
      dateLogged:'dummydate',
      expires:'dummy expire'
    },

    auth: authClient,
  };

  try {
    const response = (await sheets.spreadsheets.values.append(request)).data;
    // TODO: Change code below to process the `response` object:
    console.log(JSON.stringify(response, null, 2));
  } catch (err) {
    console.error(err);
  }
}
