我正在尝试使用microsoft-graph-client获取电子邮件列表。我获得了refresh_token并配置了App + secret。我的应用程序具有Mail.Read权限
我的代码：

const { Client } = require('@microsoft/microsoft-graph-client');
const dotenv = require('dotenv');

dotenv.config();

const clientId = process.env.OUTLOOK_CLIENT_ID;
const clientSecret = process.env.OUTLOOK_SECRET;
const tenantId = process.env.OUTLOOK_TENANT_ID;
const refreshToken = process.env.OUTLOOK_REFRESH_TOKEN;

async function getAccessToken() {
    try {
        const url = `https://login.microsoftonline.com/${tenantId}/oauth2/v2.0/token`;
        const params = new URLSearchParams();
        params.append('grant_type', 'refresh_token');
        params.append('client_id', clientId);
        params.append('client_secret', clientSecret);
        params.append('refresh_token', refreshToken);
        params.append('scope', 'https://graph.microsoft.com/.default');

        const response = await fetch(url, {
            method: 'POST',
            body: params,
        });
        // console.log(response)

        const data = await response.json();
        return data.access_token;
    } catch (error) {
        console.log(error)
    }
}

async function getNewEmails(accessToken) {
    try {
        const client = Client.init({
            authProvider: (done) => {
                done(null, accessToken);
            },
        });

        const response = await client.api("/me/messages").top(10).get()

        return response.value;
    } catch (error) {
        console.log(error)
    }
}

(async () => {
    try {
        const accessToken = await getAccessToken();
        const newEmails = await getNewEmails(accessToken);
        console.log(newEmails);
    } catch (error) {
        console.log(error)
    }
})();

字符串
我在调用“await client.API（“/me/messages”）.top（10）.get（）”函数时得到一个错误
错误代码：

}

型
我从“getToken（）”检查了access_token，它没有“undefined”，我得到了一切权利（我认为）。所以我的主要问题是获得电子邮件。我知道401意味着“未经授权”，但我不知道如何修复它。
