Can the Vue reverse proxy IP connect to the port?

Vue.js is a popular JavaScript framework that uses a reverse proxy (Reverse Proxy) to forward requests to a remote server to solve cross-domain problems. A reverse proxy is a middleware between the client and the backend server. Its function is to hide the true source address of the request sent by the client. In Vue.js, a reverse proxy can complete the following functions: receive client requests, forward requests to the remote server, return server responses, and pass responses to the client.

Reverse proxy usually requires configuring a proxy server address. This address is usually an IP address or a domain name. If you want to use a reverse proxy server in Vue.js, and the server is running on a specific port, then we need to add the port parameter after the proxy server address.

First, in the root directory of the Vue.js project, open the vue.config.js file and add the following configuration:

module.exports = {
devServer: {

proxy: {
  '/api': {
    target: 'http://127.0.0.1:3000',
    changeOrigin: true, // needed for virtual hosted sites
    pathRewrite: {
      '^/api': ''
    }
  }
}

}
}

As shown in the above code, we configured a reverse proxy server whose proxy address is "http://127.0.0.1:3000/api". Among them, "/api" represents the client request that needs to be forwarded, and "http://127.0.0.1:3000" represents the remote server address that needs to be forwarded to. If you want your proxy server to accept requests for a specific port, you can add the port number to the destination address.

For example, if the remote server is running on port 8000, then we can change the target address to "http://127.0.0.1:8000". In this way, Vue.js can successfully forward the client request to the specified remote server.

In general, the reverse proxy function of Vue.js is very powerful and can help us solve the problem of cross-domain requests, thereby simplifying front-end development work. If you need to use a reverse proxy server in Vue.js and need to specify a specific port number, you only need to add the corresponding parameters in the configuration file.
