node.js - Nodemailer gmail oauth 问题

Question

几个小时前，我能够从我的应用程序发送 gmail。我有一个 refresh_token 和一个 access_token，但当我尝试发送电子邮件时，收到错误:err: Error: Can't create new access token for user。

这似乎是nodemailer的问题，而不是我的google oauth2流程的问题。再说一次，这之前是有效的，所以我不完全确定为什么它现在坏了。如果我没有包含有用的信息，请告诉我，我会更新。

我知道，如果我不提供，nodemailer 会尝试创建它自己的 access_token，但在这里我为它提供了 access_token 和 refresh_token。我尝试排除其中之一，但仍然遇到相同的错误。

这是我的代码:

  const user = req.user;

  const myEmail = user.google.email;
  const refresh_token = user.google.refresh_token;

  const employee = await Employee.findOne({ _id: req.body.employeeId });

  const employeeEmail = employee.email;
  try {
    const oauth2Client = new OAuth2(
      process.env.OAUTH_CLIENT,
      process.env.OAUTH_SECRET,
      process.env.REDIRECT_URI
    );

    oauth2Client.setCredentials({
      refresh_token: refresh_token
    });

    let testResponse = await oauth2Client.getRequestHeaders();

    let access_token = testResponse.Authorization.split(" ")[1];

    const smtpTransport = nodemailer.createTransport({
      service: "gmail",
      tls: {
        rejectUnauthorized: false
      },
      auth: {
        type: "OAuth2",
        user: myEmail,
        clientId: process.env.OAUTH_CLIENT,
        clientSecret: process.env.OAUTH_SECRET,
        refresh_token: refresh_token,
        access_token: access_token
      }
    });

    const mailOptions = {
      from: myEmail,
      to: employeeEmail,
      subject: req.body.emailObj.subject,
      text: req.body.emailObj.message
    };

    await smtpTransport.sendMail(mailOptions, async (err, result) => {
      if (err) {
        return smtpTransport.close();
      }


      employee.response = false;
      await employee.save();

      res.send({ result });
    });
  } catch (err) {
    res.status(400).send(err);
  }
});

这是完整的错误:

我很快就明白了。在 .createTransport 身份验证选项中，我使用蛇形外壳而不是驼形外壳。多么愚蠢。
