I created the vue.config.js file
in the root directory and made related settings
module.exports = {
productionSourceMap: false,
devServer: {

// 
proxy: {
  "/v1": {
    target: "http://192.168.31.131:8080/", // 
    ws: true, // websockets
    changOrigin: true, 
    pathRequiresRewrite: {
      "^/v1": "/"
    }
  }
}

}
}
