如何从AWS Lambda调用Google API(通过Pulumi部署)

我有一个受Google OAuth保护的简单Web应用程序。因此,用户必须使用她的自定义域Google帐户登录。 Google会以令牌进行响应,应用程序可以使用令牌。它包含用户电子邮件,姓名等...

在无服务器后端上是AWS Lambda,后者又称为Google API。该网站将Google令牌发送到AWS,然后将其发送到标头Authentication: Bearer ${token}中的Google API。

问题是,Google API始终返回错误“无效的凭据”

我确保令牌的范围包含对给定API的访问权,因此我认为它应该可以工作。 我想念什么?

PS:AWS Infra的部署是通过Pulumi脚本实现的。

示例代码

const payload = JSON.stringify({ ... some object ... });

const options = {
        host: 'www.googleapis.com',
        path: '/admin/directory/v1/users',
        method: 'POST',
        headers: {
            'Content-Type': 'application/json',
            'Content-Length': payload.length.toString(),
            // Token is obtained from browser, but used in context of AWS lambda
            'Authorization': `Bearer ${token.token_id}`
        }
    };

return new Promise(function (resolve, reject) {
    try {
        let body = new Array<Buffer>();
        const request = https.request(options, function (res: any) {

            if (res.statusCode != 200) {
                reject(res.statusCode);
            }

            res.on('data', (data: any) => {                
            body.push(data);
            // It seems that the 'request.on('end') is never fired
            // I receive the data in the first batch, and that's it
            resolve(data.toString());
            });
        });

        request.on('end', () => {
            console.error('Request ended');
            // at this point, `body` has the entire request body stored in it as a string
            let result = Buffer.concat(body).toString();
            resolve(result);
        });

        request.on('error', async (err: Error) => {
        console.error('Errooooorrrr request failed');
        reject(err);
        });

        // Write the payload to the body of the request
        if (payload) {
            request.write(payload);
        };

        request.end();
    }
    catch (e) {
        console.log('Something unexpected', e);
    }
});
