我正在为Node.js使用SendGrid Web API。
我在客户端触发的方法中有以下代码。
// using SendGrid's v3 Node.js Library
// https://github.com/sendgrid/sendgrid-nodejs
const sgMail = require('@sendgrid/mail');
sgMail.setApiKey(process.env.SENDGRID_API_KEY);
const msg = {
to: '[email protected]',
from: '[email protected]',
subject: 'Sending with SendGrid is Fun',
text: 'and easy to do anywhere, even with Node.js',
html: '<strong>and easy to do anywhere, even with Node.js</strong>',
};
sgMail.send(msg);
当我触发发送方法时,我得到一个奇怪的错误(下面) - 不确定为什么会发生这种情况。希望有一些想法。
谢谢!!
错误:

首先,通过将API_KEY放在客户端,您将显示它,并且应该保密。
创建一个新文件server/smtp.js
。通过将它放在server/
目录中,Meteor只将其放在服务器端,从客户端看不到此代码:
Meteor.startup(function () {
process.env.MAIL_URL = 'smtp://username:[email protected]:587';
});
将电子邮件包添加到meteor。在命令行上:
meteor add email
创建一个文件server/methods.js
以添加一些服务器端方法:
Meteor.methods({
sendmail(to) {
// for security reasons, you should validate the 'to' argument
// but let's forget that for now.
Email.send({
from: "[email protected]",
to: to
subject: "Awesome",
text: "It worked"
});
}
});
每当您想要发送电子邮件时,在客户端调用此方法并将其传递给必要的参数:
Meteor.call('sendmail', ‘[email protected]’, (err, res) => {
if (err) {
alert(err);
} else {
// success!
}
});
希望能帮助到你。
