Question

我正在为我的网站创建一个联系表单，并且试图为SendGrid设置环境变量，但是它不起作用。

我尝试过setx SENDGRID_API_KEY 'SG.myAPIKey'，但是当我去运行代码时，它会给我消息`API密钥不是以“ SG。”开头。

如果有帮助，我有以下代码。

谢谢！

App.js

const express = require('express'); //Needed to launch server.
const bodyParser = require('body-parser');
const cors = require('cors'); //Needed to disable sendgrid security.
const sendGrid = require('@sendGrid/mail'); //Access SendGrid library to send emails.

sendGrid.setApiKey(process.env.SENDGRID_API_KEY);

//sendGrid.setApiKey('SG.myAPIKey');
const app = express(); //Alias from the express function.

app.use(bodyParser.json());

app.use(cors());

app.listen(4000, '0.0.0.0');

app.use((req, res, next) => {
    res.setHeader('Access-Control-Allow-Origin', '*');
    res.setHeader('Access-Control-Allow-Methods', 'GET, POST, PUT, PATCH, DELETE');
    res.setHeader('Access-Control-Allow-Headers', 'Content-Type, Authorization');
    next();
});

app.get('/api', (req, res, next) => {
    res.send('API Status: Running');
});

app.post('/api/email', (req, res, next) => {
    console.log(req.body);
    const msg = {
        to: 'dyzhang@gatech.edu',
        from: req.body.email,
        subject: req.body.subject,
        text: req.body.message
    }
    sendGrid.send(msg)
        .then(result => {
            res.status(200).json({
                success: true
            });
        })
        .catch(err => {
            console.log('error: ', err);
            res.status(401).json({
                success: false
            });
        });
});

Answer 1

首先在后端代码结构中创建一个.env文件在里面声明SENDGRID_API_KEY ='YOUR API KEY' 这样，您将可以通过以下方式使用Sendgrid api密钥：

process.env.SENDGRID_API_KEY

Answer 2

按照@jarivak的建议，您需要创建一个.env文件并使用process.env.SENDGRID_API_KEY，但这是推荐的方法。如果您希望将其用于测试目的，只需更改此行

sendGrid.setApiKey(process.env.SENDGRID_API_KEY);

到

sendGrid.setApiKey('YOUR API KEY');

SendGrid：设置环境变量不起作用
