crypto是nodejs自带模块，无需安装，直接使用即可。
以下代码执行完会计算出hash值并输出 config.json 文件，
const crypto = require('crypto');
const fs = require('fs');
let computedHex = () => {
let rs = fs.createReadStream('./' + zipName);
let hash = crypto.createHash('md5');
let hex
rs.on('data', hash.update.bind(hash));
rs.on('end', function() {
hex = hash.digest('hex')
console.log('hex is ' + hex);
output(hex);
});
}
let output = (hex) => {
let arr = [];
let json = {
"name": "flyme.5.0_uc_h5.zip",
"md5": hex,
"lastmodify": new Date().getTime()
};
arr.push(json);
fs.writeFile('./config.json', JSON.stringify(arr), function(err) {
if (err) throw err;
console.log('saved config.json successfully');
});
}
zipper.zip("output/release", function(error, zipped) {
if (!error) {
zipped.compress(); // compress before exporting
var buff = zipped.memory(); // get the zipped file as a Buffer
// or save the zipped file to disk
zipped.save("./" + zipName, function(error) {
if (!error) {
console.log("Ziped files successfully !");
computedHex();
}
});
} else {
console.log(error)
}
});
