nodejs 解压文件，当文件名为中文名时会出现乱码

一开始我是使用compressing 去解压的，后面一直出现乱码，于是换了个解压的包 yauzl 

具体实现步骤：

1. 安装

   npm install yauzl

   2. 封装了个解压文件方法

function unzip(zipFileName, outputDir){
        const yauzl = require('yauzl')
    return new Promise((resolve, reject) => {
        if (!fs.existsSync(outputDir)) {
            fs.mkdirSync(outputDir, { recursive: true });
        }
        
        yauzl.open(zipFileName, {lazyEntries: true}, function(err, zipfile) {
            if (err) reject(err);
            else {
                zipfile.readEntry();
                zipfile.on("entry", function(entry) {
                    if (/\/$/.test(entry.fileName)) {
                        var dir = path.join(outputDir, entry.fileName);
                        if (!fs.existsSync(dir)) {
                            fs.mkdirSync(dir, { recursive: true });
                        }
                        zipfile.readEntry();
                    } else {
                        zipfile.openReadStream(entry, function(err, readStream) {
                            if (err) reject(err);
                            else {
                                var fileName = path.join(outputDir, entry.fileName);
                                readStream.pipe(fs.createWriteStream(fileName));
                                readStream.on("end", function() {
                                    zipfile.readEntry();
                                });
                            }
                        });
                   }
               }).on("close",function(){
                 resolve("解压完成");
               });
            }
        });
    });
}

  3. 调用

 unzip(zipPath, outputPath).then(msg => console.log(msg)).catch(err => console.error(err));  // zipPath 是要解压的文件路径   outputPath是要输出的目录

     使用以上方法即可解决乱码问题
