如何在 nodejs 和 SendGrid 中发送电子邮件确认？

Question

我有一个 NodeJs 和 ReactJs 项目，用户可以在其中注册并且在用户注册后他们将收到一封电子邮件以确认他们的帐户。

所以现在当我注册时，电子邮件运行良好。但它适用于我这样设置的电子邮件。

function sendMail() {
  const msg = {
    to: "someoneemail@gmail.com", 
    from: "myemail@gmail.com", 
    subject: "a subject",
    text: "some text herer",
    html: "<strong>and easy to do anywhere, even with Node.js</strong>",
  };
  sgMail
    .send(msg)
    .then(() => {
      console.log("Email sent");
    })
    .catch((error) => {
      console.error(error);
    });
}

module.exports = { sendMail };

我需要删除这个 to: "someoneemail@gmail.com" a*

nd 而不是设置用户电子邮件，即在此注册的用户系统
而不是 text: 我必须发送令牌 .

所以这是注册部分：

router.post("/register", async (req, res) => {
  const { fullName, emailAddress, password } = req.body;
  const user = await Users.findOne({
    where: {
      [Op.and]: [{ fullName: fullName }, { emailAddress: emailAddress }],
    },
  });

  if (user) {
    res.status(400).send({
      error: `some message.`,
    });
  } else {
    bcrypt
      .hash(password, 10)
      .then((hash) => {
        return {
          fullName: fullName,
          emailAddress: emailAddress,
          password: hash,
          isVerified: false,
        };
      })
      .then((user) => {
        const token = TokenGenerator.generate();
        const creator = Verifications.belongsTo(Users, { as: "user" });
        return Verifications.create(
          {
            token,
            user: user,
          },
          {
            include: [creator],
          }
        );
      })
      .then((verification) => {
        console.log("verification", verification);
        sendMail();
      })
      .then(() => res.json("User, Successmessage "));
  }
});

但代码不在同一个文件中。

只需将您需要的参数添加到sendMail函数中即可：

function sendMail(user, token) {
  const msg = {
    to: user.emailAddress, 
    from: "myemail@gmail.com", 
    subject: "Sending with SendGrid is Fun",
    text: token,
    html: `<strong>${token}</strong>`,
  };
  sgMail
    .send(msg)
    .then(() => {
      console.log("Email sent");
    })
    .catch((error) => {
      console.error(error);
    });
}

同样在promise中注入需要的参数：

 .then(async (user) => {
        const token = TokenGenerator.generate();
        const creator = Verifications.belongsTo(Users, { as: "user" });
        await Verifications.create(
          {
            token,
            user: user,
          },
          {
            include: [creator],
          }
        );
        return {user, token};
      })
      .then(({user, token}) => {
        sendMail(user, token);
      })
      .then(() => res.json("User, Successmessage "));
