我是 Node.js 的新手，我正在尝试使用 Gmail API 创建一个邮箱，除了在电子邮件中上传附件外，一切正常。我找到了 Java、Python 和 C# 的示例，但我找不到任何关于它的节点文档。任何提示将不胜感激。

这是我的代码：

function makeBody(to, from, subject, message) {
    var str = ["Content-Type: multipart/mixed; charset=\"UTF-8\"\n",
        "MIME-Version: 1.0\n",
        "Content-Transfer-Encoding: 7bit\n",
        "to: ", to, "\n",
        "from: ", from, "\n",
        "subject: ", subject, "\n\n",
        message,
        file
    ].join('');

    var encodedMail = new Buffer(str).toString("base64").replace(/\+/g, '-').replace(/\//g, '_');

    return encodedMail;
}

function sendMessage(auth) {
    var raw = makeBody(tap, 'me', response.subject, response.content, response.files);
    gmail.users.messages.send({
        auth: auth,
        userId: 'me',
        resource: {
            raw: raw
        }
    }, function (err, response) {
        if (err) …

我有这个简单的脚本，我在 webRTC 文档中找到了我尝试运行它，但似乎我错过了一些东西

const leftVideo = document.getElementById('leftVideo');
const rightVideo = document.getElementById('rightVideo');

leftVideo.addEventListener('canplay', () => {
const stream = leftVideo.captureStream();
rightVideo.srcObject = stream;
});

我在检查流捕获时收到此错误 Uncaught DOMException: Failed to execute 'captureStream' on 'HTMLMediaElement': 无法从 HTMLVideoElement.leftVideo.addEventListener 处的跨源数据元素捕获这是我的 index.html

<video id="leftVideo" playsinline controls loop muted>
    <source src="test1.webm" type="video/webm"/>
    <p>This browser does not support the video element.</p>
</video>

<video id="rightVideo" playsinline autoplay></video>
