Question

我正在尝试使用Node.js中的请求模块，使用来自bitcoinaverage.com的API来获取比特币的当前价格。当我在localhost：3000上启动它时，我得到了页面并且HTML运行正常。我的页面有时可以工作，并且可以为我提供数据，但是大多数情况下服务器会崩溃。有时它可以工作，我不知道我的错误是什么。注意：未启用代理。

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

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

app.get("/", function (req, res) {

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

    request("https://apiv2.bitcoinaverage.com/indices/global/ticker/BTCUSD", function (error,
        response, body) {
        var data = JSON.parse(body);
        var price = data.last;
        var priceAverage = data.averages.week;
        res.send("<h1>The price of a Bitcoin now is " + price + "</h1>");
        console.log(price);
        console.log(priceAverage);
        console.log(response.statusCode);
    });
});

控制台向我显示以下内容：
