问题描述
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。
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,next) => {
res.send('API Status: Running');
});
app.post('/api/email',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
});
});
});
解决方法
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
,
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');
