Swig 不关心/了解扩展。你可以尝试写一个custom loader为你做这件事。只需复制文件系统加载程序并让它检查给定的路径是否不包含扩展名，如果包含，则使用默认值。

var fs = require('fs'),
  path = require('path');

module.exports = function (basepath, encoding) {
  var ret = {};

  encoding = encoding || 'utf8';
  basepath = (basepath) ? path.normalize(basepath) : null;

  ret.resolve = function (to, from) {
    if (basepath) {
      from = basepath;
    } else {
      from = (from) ? path.dirname(from) : process.cwd();
    }
    return path.resolve(from, to);
  };

  ret.load = function (identifier, cb) {
    if (!fs || (cb && !fs.readFile) || !fs.readFileSync) {
      throw new Error('Unable to find file ' + identifier + ' because there is no filesystem to read from.');
    }

    // Start of added code...
    var extension = path.extname(identifier);

    if (!extension) {
      // Set this to whatever you want as a default
      // If the extension exists, like 'foo.xml', it won't add the '.html'
      identifier += '.html';
    }
    // End of added code

    identifier = ret.resolve(identifier);

    if (cb) {
      fs.readFile(identifier, encoding, cb);
      return;
    }
    return fs.readFileSync(identifier, encoding);
  };

  return ret;
};
