我使用谷歌云功能通过Nodemailer发送电子邮件，邮件通过Oauth2进行身份验证。它似乎没有任何问题，电子邮件被发送，也显示在我的gmail帐户的发送电子邮件中，但实际上它们从未到达我的其他电子邮件地址。。。有人知道为什么吗？
这是我的代码
const mailTransport = nodemailer.createTransport({
name: "gmail.com",
host: "smtp.gmail.com",
port: 465,
secure: true,
auth: {
type: "OAuth2",
user: gmailEmail,
pass: gmailPassword,
clientId: clientid,
clientSecret: clientsecret,
refreshToken: clientrefreshtoken,
accessToken: clientaccesstoken,
expires: 3599,
},
});
exports.submit = functions.https.onRequest((req, res) => {
const corsMiddleware = cors(corsOptions);
corsMiddleware(req, res, () => {
if (req.method !== "POST") {
return;
}
const mailOptions = {
from: req.body.email,
replyTo: req.body.email,
to: "myemail@gmx.at",
subject: `Absender: ${req.body.email}`,
html: req.body.message,
};
mailTransport.sendMail(mailOptions);
res.status(200).send({isEmailSend: true});
});
});
提前感谢
更新！不知怎么的，我收到一些电子邮件真的很晚了，但不是所有的。更像是十分之一，我的收件箱里也有这个：

所以经过两天的尝试，我认为问题与我的代码无关。。。。gmx服务器似乎有问题，也许我在黑名单上？我不知道，帐户实际上是新的。。。永远不要从我的域发送到我的私人电子邮件工作。
这可能不是问题的原因，但您应该等待异步sendMail()执行完成后再发送响应。如果你不这样做，你就向云功能平台表明，它可以清理运行云功能的实例，而无需等待异步任务完成。
exports.submit = functions.https.onRequest((req, res) => {
const corsMiddleware = cors(corsOptions);
corsMiddleware(req, res, () => {
if (req.method !== "POST") {
return;
}
const mailOptions = {
from: req.body.email,
replyTo: req.body.email,
to: "myemail@gmx.at",
subject: `Absender: ${req.body.email}`,
html: req.body.message,
};
mailTransport.sendMail(mailOptions)
.then(() => {
res.status(200).send({isEmailSend: true});
})
});
});
