index.js： 由于显而易见的原因，条带键不完整，但在实际代码中它是。

const express = require('express')
const path = require('path')
var stripe = require('stripe')('sk_live_#');
var bodyParser = require('body-parser');
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({
  extended : true
}));

const PORT = process.env.PORT || 5000

express()
  .use(express.static(path.join(__dirname, 'public')))
  .set('views', path.join(__dirname, 'views'))
  .set('view engine', 'ejs')
  .listen(PORT, () => console.log(`Listening on ${ PORT }`))
  app.post('/ephemeral_keys', (req,res) => {  
var customerId = req.body.customer_id;
var api_version = req.body.api_version;

stripe.ephemeralKeys.create({
customer : customerId},
{stripe_version : api_version}
).then((key) =>{
res.status(200).send(key)
}).catch((err) => {
res.status(500).end()
  });
});

错误：

  

ReferenceError：app未定义

参与你的部分代码：

const express = require('express')
const path = require('path')
var stripe = require('stripe')('sk_live_#');
var bodyParser = require('body-parser');
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({
  extended : true
}));

您在哪里实例化变量应用程序？

您在宣布之前使用它。

可能你会想把它声明为：

const app = express();

您的代码应如下所示：

const express = require('express')
const path = require('path')
var stripe = require('stripe')('sk_live_#');
var bodyParser = require('body-parser');
const app = express();
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({
  extended : true
}));
