发送请求后显示{ server: { port: undefined, host: undefined } }

这个问题可能是由于您的服务器代码没有正确地设置端口和主机导致的。您可以将代码中的端口和主机设置为明确的值，例如：

const app = require('express')();
const server = require('http').createServer(app);

const PORT = 3000;
const HOST = 'localhost';

server.listen(PORT, HOST, () => {
  console.log(`Server listening on ${HOST}:${PORT}`);
});

在这个例子中，我们明确设置了端口号为3000，主机为localhost。您可以根据您的需要更改这些值，并确保它们与您在Postman中使用的值相匹配。

另外，请确保您的服务器代码正确解析POST请求的请求体数据，并将其用于后续的逻辑处理。如果您仍然遇到问题，请提供更多上下文和代码，以便我更好地帮助您解决问题。

The list of servers that constitute the quorum must be in format. OAserverid=port1,port2 OBserverid=host,host,host ocserverid=host:port, host:port Odserverid=host:port:port

The list of servers that constitute the quorum must be in the following format:

serverid=host:port:port

where `serverid` is a unique identifier for each server in the quorum, `host` is the host name or IP address of the server, and `port:port` specifies the client port and election port for the server.

For example:

server1=192.168.1.1:2888:3888
server2=192.168.1.2:2888:3888
server3=192.168.1.3:2888:3888

This specifies a quorum of three servers with IDs `server1`, `server2`, and `server3`, each with their own IP address and port numbers for client and election communication.

docker: Invalid hostPort:

The "Invalid hostPort" error in Docker usually indicates that you have specified an invalid port number when trying to map a host port to a container port.

To fix this error, make sure that the host port number you are specifying is not already in use by another process, and that it falls within the valid range of port numbers (typically 1-65535). Also, ensure that you are using the correct syntax for specifying the port mapping in your Docker command or compose file.

For example, if you want to map host port 8080 to container port 80, you would use the following syntax:

docker run -p 8080:80 my_image

If you still encounter issues, try running your Docker command with the `--verbose` flag to see more detailed error messages and troubleshoot further.
