node.js - Nodejs 应用程序中未定义请求

Question

我只是想将数据发送到 Stripe 来处理客户。但请求没有定义？这怎么可能？

错误:

13:52:17 web.1 |/Users/admin/herokutest/app/routes.js:139

13:52:17 web.1 | var stripeToken = req.body.stripeToken;

13:52:17 web.1 | ReferenceError:未定义请求

App.js 文件:

var stripeToken = req.body.stripeToken;

function subscribeUser(token, res){
    stripe.customers.create({
        card: stripeToken,
        plan: 'standard',
        email: 'test@test.test'
    }, function(err, customer) {
        if (err) {
            res.send({ok: false, message: 'Uh oh. there was a problem processing your card (error: ' + JSON.stringify(err) + ')'});
        } else {
            res.send({ok: true, message: 'Perfect, you have been subscribed to a plan'}),
            res.render('subscribe', { title: 'Congratulations!' })
        }
    });
}

app.post('/getstarted3', function (req, res) {
  subscribeUser();
  res.render('subscribe', { title: 'Welcome' }); // load the index.jade file    
});

行 var stripeToken = req.body.stripeToken; 不在正确的范围内，您将其置于请求处理程序之外。

此外，您没有向 subscribeUser() 传递任何参数，并且您尝试多次响应同一请求。我猜你想要这样的东西:

function subscribeUser(token, res){
    stripe.customers.create({
        card: token,
        plan: 'standard',
        email: 'test@test.test'
    }, function(err, customer) {
        if (err) {
            res.send({ok: false, message: 'Uh oh. there was a problem processing your card (error: ' + JSON.stringify(err) + ')'});
        } else {
            res.send({ok: true, message: 'Perfect, you have been subscribed to a plan'}),

            // you can't respond to a request twice, it's one or the other ...
            //res.render('subscribe', { title: 'Congratulations!' })
        }
    });
}

app.post('/getstarted3', function (req, res) {
  subscribeUser(req.body.stripeToken, res);

  // you can't respond multiple times to the same request
  //res.render('subscribe', { title: 'Welcome' }); // load the index.jade file    
});
