条纹：必须提供来源或客户

Question

我正在尝试将Stripe集成到我的购物车项目中。我无法提交结帐表格。我不断收到此错误消息：“必须提供来源或客户。”
我没有正确设置我的Stripe帐户，或者我的JavaScript中缺少某些参数。我已经花了几个小时解决这个问题，但仍然无法解决。

这来自Stripe的日志：
解析的请求POST正文

{
  "amount": "21000",
  "currency": "usd",
  "description": "Test Charge"
}

反应体

{
  "error": {
    "type": "invalid_request_error",
    "message": "Must provide source or customer."
  }
}

这是我的app.js

var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var expressHbs = require('express-handlebars');
var mongoose = require('mongoose');
var session = require('express-session');
var passport = require('passport');
var flash = require('connect-flash');
var validator = require('express-validator');
var MongoStore = require('connect-mongo')(session);

var routes = require('./routes/index');
var userRoutes = require('./routes/user');

var app = express();

mongoose.connect('localhost:27017/shopping');
require('./config/passport');

// view engine setup
app.engine('.hbs', expressHbs({defaultLayout: 'layout', extname: '.hbs'}));
app.set('view engine', '.hbs');

// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.use(validator());
app.use(cookieParser());
app.use(session({
    secret: 'mysupersecret', 
    resave: false, 
    saveUninitialized: false,
    store: new MongoStore({ mongooseConnection: mongoose.connection }),
    cookie: { maxAge: 180 * 60 * 1000 }
}));
app.use(flash());
app.use(passport.initialize());
app.use(passport.session());
app.use(express.static(path.join(__dirname, 'public')));

app.use(function(req, res, next){
    res.locals.login = req.isAuthenticated();
    res.locals.session = req.session;
    next();
});

app.use('/user', userRoutes);
app.use('/', routes);

// catch 404 and forward to error handler
app.use(function(req, res, next) {
  var err = new Error('Not Found');
  err.status = 404;
  next(err);
});

// error handler
app.use(function(err, req, res, next) {
  // set locals, only providing error in development
  res.locals.message = err.message;
  res.locals.error = req.app.get('env') === 'development' ? err : {};

  // render the error page
  res.status(err.status || 500);
  res.render('error');
});

module.exports = app;

这是我的index.js：

var express = require('express');
var router = express.Router();
var Cart = require('../models/cart');

var Product = require('../models/product');

/* GET home page. */
router.get('/', function(req, res, next) {
    var successMsg = req.flash('success')[0];
    Product.find(function(err, docs) {
        var productChunks = [];
        var chunkSize = 3;
        for (var i = 0; i < docs.length; i += chunkSize) {
            productChunks.push(docs.slice(i, i + chunkSize));
        }
        res.render('shop/index', { title: 'Shopping Cart', products: productChunks, successMsg: successMsg, noMessages: !successMsg});
    });
});

router.get('/add-to-cart/:id', function(req, res, next) {
    var productId = req.params.id;
    var cart = new Cart(req.session.cart ? req.session.cart : {});

    Product.findById(productId, function(err, product){
        if (err) {
            return res.redirect('/');
        }
        cart.add(product, product.id);
        req.session.cart = cart;
        console.log(req.session.cart);
        res.redirect('/');
    });
});

router.get('/shopping-cart', function(req, res, next) {
    if (!req.session.cart) {
        return res.render('shop/shopping-cart', {products: null});
    }
    var cart = new Cart(req.session.cart);
    res.render('shop/shopping-cart', {products: cart.generateArray(), totalPrice: cart.totalPrice});
});

router.get('/checkout', function(req, res, next) {
    if (!req.session.cart) {
        return res.redirect('/shopping-cart');
    }
    var cart = new Cart(req.session.cart);
    var errMsg = req.flash('error')[0];
    res.render('shop/checkout', {total: cart.totalPrice, errMsg: errMsg, noError: !errMsg});
});

router.post('/checkout', function(req, res, next) {
    if (!req.session.cart) {
        return res.redirect('/shopping-cart');
    }
    var cart = new Cart(req.session.cart);
    var stripe = require("stripe")(
      "**hidden**"
    );

    stripe.charges.create({
      amount: cart.totalPrice * 100,
      currency: "usd",
      source: req.body.stripeToken,
      description: "Test Charge"
    }, function(err, charge) {
        if (err) {
            req.flash('error', err.message);
            return res.redirect('/checkout');
        }
        req.flash('success', 'Successfully bought product!');
        req.cart = null;
        res.redirect('/');
    });
});

module.exports = router;

这是我的checkout.js：

Stripe.setPublishableKey('**hidden**');

var $form = $('checkout-form');

$form.submit(function(event) {
    $('#charge-errors').addClass('hidden');
    $form.find('button').prop('disabled', true);
    Stripe.card.createToken({
      number: $('#card-number').val(),
      cvc: $('#card-cvc').val(),
      exp_month: $('#card-expiry-month').val(),
      exp_year: $('#card-expiry-year').val(),
      name: $('#card-name').val()
    }, stripeResponseHandler);
    return false;
});

function stripeResponseHandler(status, response) {
    if (response.error) { // Problem!

    // Show the errors on the form
    $('#charge-errors').text(response.error.message);
    $('#charge-errors').removeClass('hidden');
    $form.find('button').prop('disabled', false); // Re-enable submission

  } else { // Token was created!

    // Get the token ID:
    var token = response.id;

    // Insert the token into the form so it gets submitted to the server:
    $form.append($('<input type="hidden" name="stripeToken" />').val(token));

    // Submit the form:
    $form.get(0).submit();
  }
};

这是我的结帐表格（.hbs）：

Answer 1

Stripe的付款流程分为两个步骤：

1. 在客户端，您可以使用Checkout或Elements在前端代码中收集并标记客户的付款信息，然后将生成的令牌发送到后端服务器。

2. 在服务器端，在后端代码中，您可以在API请求中使用令牌，例如创建费用或客户。

您共享的代码是第一步。但是，您提到的错误消息：

必须提供来源或客户。

发生在第二步。当您发送不带或参数的费用创建请求时，Stripe的API返回此错误。sourcecustomer

您需要检查服务器端代码以找出问题所在。您还可以在仪表板中查看集成发送的所有请求的日志：https
