request流形式下载文件,文件保存不完整
使用request模块,下载服务器上的文件,使用stream的方式下载,如果先pause下,过段时间在resume,最后下载下来的文件 不完整,服务器上的文件是正常的
代码如下所示:
'use strict';
const request = require('request');
const timeout = 1000 * 60 * 3;
const fs = require('fs');
const path = require('path');
const sss = path.join(__dirname, '123123213.dmg');
const url = 'http://p2oryw9jc.bkt.clouddn.com/charles-proxy-4.1.4.dmg';
let inStream = request.get(url);
inStream.pause();
inStream.pipe(fs.createWriteStream(sss));
setTimeout(() => {
inStream.resume()
}, timeout)
请问这是原因造成的呢,谢谢大家了

我没有尝试过类似的事情,但是是否可以监听一下response事件或者error时间,打印一下? 类似: inStream .on(‘response’, function(response) { console.log(response); }) .on(‘error’, function(err) { console.log(err); });
data 事件 会接受到部分数据
error 事件
{ Error: read ECONNRESET
at exports._errnoException (util.js:1022:11)
at TCP.onread (net.js:610:25) code: 'ECONNRESET', errno: 'ECONNRESET', syscall: 'read' }
我感觉貌似是请求断开了 response 事件

inStream.on(‘error’, () => console.log(error)), read timeout 在 linux 中一般都是 20 〜 120s,出现这个问题一般都是服务端主动断开了, 应该就是在120s那个点左右,你可以把 timeout 设置小点, 或者服务端 timeout 设置大点
@guo-q @mosaic101 @JacksonTian 谢谢各位的回答了 现在的业务场景是服务器端需要做文件打包下载,然后文件都是保存在云存储上的,然后我这里选择的解决方案是 jszip + request
jszip添加stream
zip.file(‘name’, request.get(item.downLoadUrl));
然后现在遇到问题的是如果有多个文件的话,会添加多个file,就像上面的形式,但是我研究了下jszip的源码,貌似如果对多个文件的话,是先把stream放在一个数组里面的,然后依次执行,其它的stream会先pause,等前一个执行完成后,下一个stream会resume,这样会出现上面的问题。 下面是我的一个测试代码
'use strict';
const JSZip = require('jszip');
const request = require('request');
const fs = require('fs');
const path = require('path');
const sss = path.join(__dirname, 'me.zip');
const resultArr = [
{
fileName: 'charles-proxy-4.1.4.dmg',
downLoadUrl: 'http://p2oryw9jc.bkt.clouddn.com/charles-proxy-4.1.4.dmg'
},
{
fileName: 'googlechrome_mac_59.0.3071.109.dmg',
downLoadUrl: 'http://p2oryw9jc.bkt.clouddn.com/googlechrome_mac_59.0.3071.109.dmg'
}
];
const zip = new JSZip();
resultArr.map(item => {
let inStream = request.get(item.downLoadUrl);
let name = item.fileName;
let length = 0;
inStream
.on('response', function (response) {
console.error(name + '--content-type--', response.headers); // 'image/png'
})
.on('data', function (data) {
length += data.length;
})
.on('error', function (e) {
console.error(name + '---error---->', e);
})
.on('end', function () {
console.error(name + '---end---- length:'+ length);
});
zip.file(item.fileName, inStream);
});
const stream = zip.generateNodeStream({type: 'nodebuffer', streamFiles: true});
stream.pipe(fs.createWriteStream(sss));
stream
.on('data', function (data, metadata) {
})
.on('error', function (e) {
console.error('---error-----', e);
})
.on('end', function () {
console.error('---end-----');
});
```
不知道大家有什么其它的解决方案吗
