Heroku 部署的应用程序没有发送正确的响应，而如果我在本地运行 heroku 使用 heroku 本地 Z2567A5EC9705EB7AC2C984033 得到正确的响应

Question

我正在尝试将 node+express+mongo 部署到 heroku 中。

index.js

const PORT = process.env.PORT || 3200;

const CONNECTION_URL =
  "mongodb+srv://aarthi:C<password>@cluster0.prt4u.mongodb.net/BookMyShow?retryWrites=true&w=majority";

mongoose
  .connect(CONNECTION_URL, { useNewUrlParser: true, useUnifiedTopology: true })
  .then(() =>
    app.listen(PORT, () =>
      console.log(
        `Server Running on Port:https://immense-sands-26614.herokuapp.com/`
      )
    )
  )
  .catch((error) => console.log(`${error} did not connect`));

package.json

{
  "name": "hackathon_server",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "type": "module",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start": "nodemon index.js"
  },
  "keywords": [
    "example",
    "heroku"
  ],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "cors": "^2.8.5",
    "express": "^4.17.1",
    "mongodb": "^3.6.6",
    "mongoose": "^5.12.3",
    "nodemon": "^2.0.7",
    "validator": "^13.5.2"
  },"engines": {
    "node": "14.15.1"
  }
}

现在我正在尝试使用本地 heroku 使用 heroku 本地 web 运行节点

:47:13 pm web.1 |  [nodemon] 2.0.7
4:47:13 pm web.1 |  [nodemon] to restart at any time, enter `rs`
4:47:13 pm web.1 |  [nodemon] watching path(s): *.*
4:47:13 pm web.1 |  [nodemon] watching extensions: js,mjs,json
4:47:13 pm web.1 |  [nodemon] starting `node index.js`
4:47:17 pm web.1 |  (node:33016) DeprecationWarning: collection.ensureIndex is deprecated. Use createIndexes instead.
4:47:17 pm web.1 |  (Use `node --trace-deprecation ...` to show where the warning was created)
4:47:17 pm web.1 |  Server Running on Port:https://immense-sands-26614.herokuapp.com/

同时击中 postman api req 得到正确响应

本地运行时的 api req

但是当我点击部署的 heroku 应用程序的请求时，出现错误Deployed Heroku 应用程序

我看到部署的 heroku 的控制台上正在运行什么，看起来不错

web heroku 上的控制台

不确定是什么问题。 有人请帮忙解决这个问题

Answer 1

终于弄清楚了问题所在。

我通过不支持的 https:// 发送请求

将我的请求 url 更改为 http://... http://immense-sands-26614.herokuapp.com/api/movies
