node.js - Nodemailer gmail oauth问题

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access_token，但是当我尝试发送电子邮件时，出现错误：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。再说一次，这是较早的工作，所以我不完全确定为什么现在坏了。如果我没有提供有用的信息，请告诉我，我会进行更新。

我了解到，如果我不提供它，nodemailer会尝试创建它自己的access_token，但是在这里，我同时为它提供了access_token和refresh_token。我尝试排除一个和另一个，但是仍然出现相同的错误。

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);
  }
});

这是整个错误：

最佳答案

我很快就知道了。在.createTransport auth选项中，我将密钥装在外壳中而不是骆驼式安装。真蠢
