Question


const express = require("express");
const bodyParser = require("body-parser");
const https = require("https");

const app = express();
app.use(express.static(__dirname+"/public"));
app.use(bodyParser.urlencoded({extended:true}));

app.get("/", function(req,res){
    res.sendFile(__dirname+"/signup.html");
});

app.post("/", function(req,res){
    const firstName = req.body.fName;
    const  lastName = req.body.lName;
    const email = req.body.email;
    const data = {
        members:[
            {
                email_address:email,
                status:"subscribed",
                merge_fields:{
                    FNAME:firstName,
                    LNAME:lastName
                }

            }
        ]
    };

    const jsonData = JSON.stringify(data);
    const url = "https://us19.api.mailchimp.com/3.0/lists/listkey";
    const options= {
        method:"POST",
        auth:"username23:apikey-us45"
    }

   const request =  https.request(url, options, function(resonse){
       if(resonse.statusCode === 200){
           res.sendFile(__dirname+"/success.html");
       }
       else{
           res.sendFile(__dirname+"/failure.html")
       }
        resonse.on("data",function(data){
            console.log(JSON.parse(data));
        });
     });

     request.write(jsonData);
     request.end();

});

app.post("/failure",function(req,res){
    res.redirect("/");
});

app.listen(process.env.PORT || 3000, function(){
       console.log("Server running on port 3000")

});

此代码在本地运行良好，但在部署到heroku之后；什么时候我单击我的提交按钮，以便我的app.js可以处理我的数据并使用mailchimp api向mailchimp发送请求...它一直显示浏览器和heroku日志上的“内部服务器错误”报告了此情况。
