我想从我的 GitLab 存储库下载（而不是克隆）存档，但我收到此错误

不正确的标头检查 (Zlib._handle.onerror)

这是我的功能：

var fs = require('fs');
var url = require('url');
var https = require('https');
var path = require('path');
var targz = require('tar.gz');

function downloadFile(source, destination, name) {
    var options = {
        host: url.parse(source).host,
        port: 443,
        path: url.parse(source).pathname
    };

    var file = fs.createWriteStream(destination + path.sep + name);

    https.get(options, function(res) {
        res.on('data', function(data) {
            file.write(data);
        }).on('end', function() {
            file.end();
            console.log('File ' + name + ' downloaded to ' + destination);

            targz().extract(destination + '/' + name, destination)
                .then(function(){
                    console.log('Job done!');
                })
                .catch(function(err){
                    console.log('Something is wrong ', err.stack);
                });
        });
    });
}

下载的文件类型为 tar.gz。我尝试设置一些标题但不成功。源参数就像：https ://gitlab.com/api/v3/projects/:ID/repository/archive?token=XXYYZZ

请问有什么帮助吗？

问题是模块未正确下载您的文件https，导致模块提取错误tar.gz。

您可以使用与withrequest协调的模块将提取直接通过管道传输到目标文件夹：tar.gzcreateWriteStream

var request = require('request');
var targz = require('tar.gz');

function downloadFile(source, destination, cb) {
    var read = request.get(source);
    var write = targz().createWriteStream(destination);

    read.pipe(write);

    write.on('finish', function() {
        cb(null);
    });

    write.on('error', function(err) {
        cb(err);
    });
}

var source = "https://gitlab.com/api/v3/projects/:ID/repository/archive?token=XXYYZZ";
var destination = "/home/user/some/dir";

downloadFile(source, destination, function(err) {
    if (err) {
        console.log('Something is wrong ', err.stack);
    } else {
        console.log('Job done!');
    }
});

请注意，finish要调度事件，您需要以下版本1.0.2（tar.gz请参阅此问题）：

npm install tar.gz@1.0.2
