NodeJsプロジェクトのIPアドレスとポートを修正します.

プロジェクト下のconfigディレクトリのindex.jsのファイルを修正します.オンラインで見たソリューションを参照してください.https://segmentfault.com/q/1010000012132756?sort=created
修正箇所は://Varous Dev Server settings host:‘192.168.0.100’、/can be overwritten byprocess.env.HOST port:8080、
このうち、Ipが'0.0.00'であれば、デフォルトはローカルネットワークのIPであっても良いし、本機のIPであっても良いです.
自分のindex.jsファイルの内容は以下の通りです.
