Heroku部署的应用程序没有发送正确的响应，而如果我使用Heroku本地网站在本地运行Heroku，我会得到正确的响应

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`));

软件包.json

"nodemon": "^2.0.7",
"validator": "^13.5.2"
},"engines": {

}
}

现在我正在尝试使用本地heroku运行节点，使用heroku本地web

: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 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/

同时点击poster api req获得正确的响应

本地运行时的api请求

但当我点击已部署heroku应用程序的请求时，Getting error部署的Heroku应用

我看到了部署的heroku控制台上运行的内容，它似乎很好

网站上的控制台heroku

不确定问题出在哪里。请有人帮忙解决这个

最终解决了这个问题。

我通过https://发送请求，这不支持

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