节点上websocket服务器的connect ECONNREFUSED::1:3000错误

webpack node.js javascript

whitebear · 技术社区 · 2 年前

我正在用wscat测试我的本地服务器。

% wscat -c ws://localhost:3000
error: connect ECONNREFUSED ::1:3000
> %

以某种方式 Connection is refused.

然而 curl localhost:3000 作品

$curl localhost:3000
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Error</title>
</head>
<body>
<pre>Cannot GET /</pre>
</body>
</html>

我的服务器如下所示。

const path = require('path');
const { merge } = require('webpack-merge');
const BundleTracker = require('webpack-bundle-tracker');

const entries = {}
for (const fileName of require('fs').readdirSync(path.resolve(__dirname, 'static', 'entries'))) {
  entries[fileName.split('.')[0]] = `./static/entries/${fileName}`
}

const baseConfig = {
  entry: entries,  
  output: {
    filename: 'js/[name].[hash].bundle.js',
    path: path.resolve(__dirname, 'dist'),
  },
  optimization: {
    splitChunks: {
      cacheGroups: {
        commons: {
          test: /[\\/]node_modules[\\/]/,
          chunks: 'initial', 
          name: 'vendor',
        },
      },
    },
  },
  
  module: {
    rules: [
      {
        test: /\.css$/,
        use: ['style-loader', 'css-loader'],
      },
    ],
  },
  plugins: [
    // â è¿½å  â
    new BundleTracker({
      path: __dirname,
      filename: 'webpack-stats.json',
    }),
  ]
};

const devConfig = merge(baseConfig, {
  mode: 'development',
  output: {
    // Django ãèªã¿ã«æ¥ã(dev)
    publicPath: 'http://localhost:3000/static/',
  },
  devServer: {
    port: 3000,
    hot: true,
    host: '0.0.0.0',
    //watchOptions: {
    //  ignored: /node_modules/
    //},
    headers: {
        "Access-Control-Allow-Origin": "*"
    },
  },

});

const productConfig = merge(baseConfig, {
  mode: 'production',
  output: {
    publicPath: '/static/'
  }
})

module.exports = (env, options) => {
  return options.mode === 'production' ? productConfig : devConfig
}

然后我用这个命令启动了服务器。

看起来像 http://localhost:3000 效果很好,但是 ws://localhost:3000 不起作用。

我应该在哪里检查websocket服务器?

我该怎么解决这个问题?
