js解压字符串

1. 如何用js压缩字符串长度在用php还原

一个超长字符串有由PHP进行压缩,得到压缩后字符串,再由浏览器的javascript进行解压缩得到原字符串.
有没有这样的插件,或者算法,函数,方法,类等工具，我还是毕竟推荐你去后盾人看看，里面有很多关于php的这类视频，你可以去看看

2. node.js同步怎么解压文件

搜到一个只能解压缩的 https://github.com/nearinfinity/node-unzip
fs.createReadStream('path/to/archive.zip').pipe(unzip.Extract({ path: 'output/path' }));
var readStream = fs.createReadStream('path/to/archive.zip');var writeStream = fstream.Writer('output/path');fs.createReadStream('path/to/archive.zip')
.pipe(unzip.Parse())
.on('entry', function (entry) {
var fileName = entry.path;
var type = entry.type; // 'Directory' or 'File'
var size = entry.size;

//process the entry or pipe it to another stream
...
});
