1、propertiesParser.js
let readline = require('readline'); let fs = require('fs');
// properties文件路径 let local = 'zh', url = local == 'zh' ? /public/messages_zh.properties' : '/public/messages_en.properties';
// Unicode 码转为中文 let toGB2312 = function(str) { return unescape(str.replace(/\\u/gi, '%u')); }
// properties文件解析 let parseProps = function() { let fRead = fs.createReadStream(url), readlineObj = readline.createInterface({ input: fRead }); readlineObj.on('line', (line) => { var tmp = line.toString(), index = tmp.indexOf('#'); // 拆分key、value if (index != 0) { let strIdx = tmp.indexOf('='), key = tmp.substr(0, strIdx), value = tmp.substr(strIdx + 1); // 将拆分key、value数据存储到node的全局变量global下的local属性 global.local[key] = local == 'zh' ? toGB2312(value) : value; } })
// 文件读取结束 readlineObj.on('close', () => { console.log('readline close... parsed properties!'); }) } module.exports = { parseProps }
网上也有jquery.i18n.properties等方案,感觉引入过多冗余资源,索性手撸一个纯js方法实现解析,希望也能帮到遇到类似问题的人 ^_^ 。
