要求文件为字符串

如果是针对（少数）特定扩展名的，则可以添加自己的

require.extensions

var fs = require('fs');require.extensions['.txt'] = function (module, filename) {    module.exports = fs.readFileSync(filename, 'utf8');};var words = require("./words.txt");console.log(typeof words); // string

否则，您可以

fs.readFile

require.resolve

var fs = require('fs');function readModuleFile(path, callback) {    try {        var filename = require.resolve(path);        fs.readFile(filename, 'utf8', callback);    } catch (e) {        callback(e);    }}readModuleFile('./words.txt', function (err, words) {    console.log(words);});
