1.webpack4的版本写法

class AddPrefixPlugin {
  apply(compiler) {
    compiler.hooks.compilation.tap('AddPrefixPlugin', (compilation) => {
      HtmlWebpackPlugin.getHooks(compilation).beforeEmit.tapAsync(
        'AddPrefixPlugin',
        (data, cb) => {
          // 使用正则表达式替换所有包含 /static/file/ 的路径
          data.html = data.html.replace(/\/static\/file\//g, '/zhgdxmf/static/file/');
          cb(null, data);
        }
      );
    });
    compiler.hooks.emit.tapAsync('AddPrefixPlugin', (compilation, callback) => {
      // 遍历所有输出的资源文件，替换其中的 /static/file/ 路径
      Object.keys(compilation.assets).forEach((assetName) => {
        if (assetName.endsWith('.js') || assetName.endsWith('.html')) {
          let content = compilation.assets[assetName].source();
          content = content.replace(/\/static\/file\//g, '/zhgdxmf/static/file/');
          compilation.assets[assetName] = {
            source: () => content,
            size: () => content.length
          };
        }
      });
      callback();
    });
  }
}

module.exports = AddPrefixPlugin;

webpack 2 的版本

function AddPrefixPlugin(options) {
  this.options = options || {};
}

AddPrefixPlugin.prototype.apply = function(compiler) {
  compiler.plugin('compilation', (compilation) => {
    compilation.plugin('html-webpack-plugin-before-html-processing', (htmlPluginData, callback) => {
      // 使用正则表达式替换所有包含 /static/file/ 的路径
      htmlPluginData.html = htmlPluginData.html.replace(/\/static\/file\//g, '/zhgdxmf/static/file/');
      callback(null, htmlPluginData);
    });

    compilation.plugin('optimize-assets', (assets, callback) => {
      // 遍历所有输出文件，替换其中的 /static/file/ 路径
      Object.keys(assets).forEach((assetName) => {
        if (assetName.endsWith('.js') || assetName.endsWith('.html')) {
          let content = assets[assetName].source();
          content = content.replace(/\/static\/file\//g, '/zhgdxmf/static/file/');
          assets[assetName] = {
            source: () => content,
            size: () => content.length
          };
        }
      });
      callback();
    });
  });
};

module.exports = AddPrefixPlugin;
