一个简化的Webpack插件示例，用于自动上传sourceMap文件到服务器
这个插件会在每次编译后寻找sourceMap文件，并将其上传到指定的服务器。这个例子假设服务器支持HTTPS，并且上传是通过POST请求实现的。根据实际情况，可能需要调整上传逻辑。

const fs = require('fs');
const path = require('path');
const https = require('https');
 
class AutoUploadSourceMapPlugin {
  constructor(options) {
    this.options = options;
  }
 
  apply(compiler) {
    compiler.hooks.afterEmit.tapAsync('AutoUploadSourceMapPlugin', (compilation, callback) => {
      const assetNames = Object.keys(compilation.assets);
      const sourceMapAssetName = assetNames.find((name) => /\.map$/.test(name));
 
      if (!sourceMapAssetName) {
        callback();
        return;
      }
 
      const sourceMapPath = path.join(compilation.options.output.path, sourceMapAssetName);
      const sourceMapContent = fs.readFileSync(sourceMapPath, 'utf-8');
 
      const uploadOptions = {
        hostname: this.options.hostname,
        port: this.options.port,
        path: this.options.path,
        method: 'POST',
        headers: {
          'Content-Type': 'application/json',
          'Content-Length': sourceMapContent.length
        }
      };
 
      const req = https.request(uploadOptions, (res) => {
        if (res.statusCode < 200 || res.statusCode >= 300) {
          console.error(`Upload failed with status code: ${res.statusCode}`);
        } else {
          console.log('SourceMap uploaded successfully');
        }
        callback();
      });
 
      req.on('error', (e) => {
        console.error(`Upload error: ${e.message}`);
        callback();
      });
 
      req.write(sourceMapContent);
      req.end();
    });
  }
}
 
module.exports = AutoUploadSourceMapPlugin;

使用这个插件的方法是在webpack配置文件中如下配置：

const AutoUploadSourceMapPlugin = require('./AutoUploadSourceMapPlugin');
 
module.exports = {
  // ... 其他webpack配置
  plugins: [
    new AutoUploadSourceMapPlugin({
      hostname: 'your-server.com',
      port: 443,
      path: '/path/to/upload/sourceMap'
    })
  ]
};
