未定义NodeJS Google Cloud功能请求

Question

I'm trying to write some NodeJS for a google cloud function to process stripe. I'm pretty new to this and trying to follow various tutorials.

I currently get the following error:

 Detailed stack trace: ReferenceError: request is not defined

I don't really understand since request I thought is part of express package. This is my entire code. It's designed to take a token from the form and create a charge. Even looking at the stripe tutorial they don't separately define request.

var app = require('express')();
var http = require('http').Server(app);
var stripe = require('stripe')(
  "sk_);
var bodyParser = require('body-parser');

app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());

//get token from body
const token = request.body.stripeToken;

//initiate a one-off charge for a customer
exports.chargeCustomer = app.get("/", function      chargeCustomer (req,res){
stripe.charges.create({
source: token,
currency: 'usd',
amount:999
 },function(err, charge) {
  if(err) {
  return res.send(JSON.stringify(err));
  }
  res.send(JSON.stringify(charge));
  });
  });

I'm not sure what tutorial you followed, so can't point to that. What's missing from your code is the first request to the tokens endpoint that creates the card token, which is needed for the subsequent charges call.

var stripe = require("stripe")("sk_test_XXXXXXX"); // your test key

stripe.tokens.create({
  card: {
    number: '4242424242424242',
    exp_month: 12,
    exp_year: 2020,
    cvc: '123'
  }
}, function(err, token) {
  // asynchronously called
});

The result of this will return a JSON object, and you will need the id of that object. The ID is a string starts with tok_ , ie tok_0EDyAkDOjEFp8g5k9NxTrm2k
