Question

我在诺德创建了一个简单的亚特兰大,并在一个以安普顿图为基地的EC2级案例中将其部署。我还在我的EC2上安装了 no。我曾试图从PPOSTMAN发出一份PPOST申请,并附上JSON档案。我的APICS将从收到的POST申请中提取所需数据,并将储存在Mongo Atlas服务器上。我复制了我的私人IP地址,在POSTMAN使用。我可以听到的是,会议时间已经很短。

我只需要能够向我的欧共体2级法院发出一份《特别行动计划》要求。

我的服务器代码如下:

const http = require( http ); const app=require( ./app.js );
const port=process.env.PORT || 3001;
const server=http.createServer(app);
server.listen(port);

这是我的ur式:

https://ec2-xxxx-xxxx-xxxx-xxxx.us-east-2.compute.amazonaws.com:3001/products

为此,我发现PPOSTMAN的错误:

rror: 请求书已送达。

当我尝试一种不同的格式xx.xxxxxx.xxxx/3001/products时, 我有不同的错误:

Error:link ECONNREFUSED。

我认为,我的格式有些错误,我不相信。

Answer 1

3. 您的EC2 能够接收来自互联网的吉大港山区的申请:

The EC2 instance needs to be in a public subnet

The EC2 needs a public IP address

The Security Group associated with the EC2 instance should permit Inbound traffic on port 80 from a source of 0.0.0.0/0 (or, for testing purposes, just the public IP address associated with your own computer -- use https://icanhazip.com/)

如果它仍然不工作,则试图与EC2案例连接,并填写curl localhost,以证实网络服务器正在运行。

Answer 2

Here s my server code-

const http://www.un.org。

const port=process.env.PORT || 3001;

const server=http.createServer(app);

服务器。

this is my url format- https://ec2-xxxx-xxxx-xxxx-xxxx.us-east-2.compute.amazonaws.com:3001/products. For this, I get this error on POSTMAN- Error: Request timed out. And when I try a different format-xxxx.xxxx.xxxx.xxxx/3001/products, I get a different error-Error: connect ECONNREFUSED. I think there s something wrong with my format, I am not sure.
