我正在尝试从公开的Google表格中访问数据。该工作表具有对任何人的只读访问权限。我正在使用official Node.js client。我使用服务帐户来验证请求,因为我使用相同的服务帐户访问另一张无法公开的工作表。
代码运行正常,但是一旦我将Node.js客户端更新到最新版本,它就开始给我带来奇怪的错误。我已经为错误创建了一个缩小的示例,这里是代码 -
/*eslint-disable no-console */
const { promisify } = require('util');
const GoogleAuth = require('google-auth-library');
const { google } = require('googleapis');
const googleAuth = new GoogleAuth();
const sheets = google.sheets('v4');
sheets.spreadsheets.values.getAsync = promisify(sheets.spreadsheets.values.get);
async function authorizeWithServiceAccount(serviceAccountKey, scopes) {
try {
let authClient = await authorize(serviceAccountKey, scopes);
return authClient;
} catch (err) {
console.error(err);
throw err;
}
}
function authorize(credentials, scopes) {
return new Promise((resolve, reject) => {
googleAuth.fromJSON(credentials, (err, client) => {
if (err) {
console.error(err);
reject(err);
return;
}
client.scopes = scopes;
client.authorize((err, result) => {
if (err) {
console.error(err);
reject(err);
return;
}
console.log(result, true);
resolve(client);
});
});
});
}
async function getData(auth, spreadsheetId, range) {
try {
return sheets.spreadsheets.values.getAsync({
auth: auth,
spreadsheetId: spreadsheetId,
range: range
});
} catch (e) {
console.error(e);
throw e;
}
}
const serviceAccountJson = require('../configs/keys/service_account'); //The service account json key
const spreadsheetId = 'SPREADSHEET_ID'; // Id of the sheet I am trying to access
const apiKey = 'THE_API_KEY'; //Any API key generated on Google's API console
const range = 'A:M';
async function init() {
let authClient = await authorizeWithServiceAccount(serviceAccountJson, [
'https://www.googleapis.com/auth/spreadsheets.readonly'
]);
return getData(authClient, spreadsheetId, range); //This doesn't work and throw error
// return getData(apiKey, spreadsheetId, range); //This does work and return all the data.
}
init()
.then(result => {
console.log('Received Data');
console.log(result.data);
})
.catch(e => console.error(e));
因此,如果我使用API密钥而不是服务帐户作为auth参数,我会按预期获得正确的数据。但是,只要我使用服务帐户,result.data
就会变为undefined
,然后我就会收到此错误。

我之前使用googleapis库版本25.x并且当时服务帐户auth正在运行,但是一旦我将其更新为28.x,它就会停止工作。
有没有办法在28.x googleapis node.js客户端中使用服务帐户而不是API密钥?我不能降级它,因为我使用的是需要最新版本的其他Google API。

好的,我再次看了documentation,他们在一个地方about how to do it提到了它。我以前使用像这样的google-auth库 -
const GoogleAuth = require('google-auth-library');
const googleAuth = new GoogleAuth();
在前面的文档中提到过。我想在表格API的文档中,无法记住。但他们现在正在使用googleapis包和工作表API支持auth。因此我所要做的就是切换到使用auth。所以这就是我现在获得authClient的方式,并且它正在进行测试。
const { google } = require('googleapis');
const authClient = await google.auth.getClient({
credentials: credentials,
scopes: scopes
});
现在,我正在使用最新的googleapis package / Node.js client获取正确的数据。
所以问题是我如何获得authClient。较旧的方式似乎与最新的客户端不兼容。

理论:sheets.values.get做得很奇怪,promisify
无效。
可能的解决方法:
手动promisify
getData
async function getData(auth, spreadsheetId, range) {
return new Promise((resolve, reject) => {
sheets.spreadsheets.values.get({
auth: auth,
spreadsheetId: spreadsheetId,
range: range
}, (error, result) => {
if (error) {
return reject(error);
}
resolve(result);
});
});
}
