使用 Node.js 从私有存储库下载 zip 版本

Question

我正在尝试从私人存储库下载 zip 版本，我尝试了很多解决方案，但似乎都不起作用。

这是我的代码：

function Download(url, path, options) {
updateHeader(options.stageTitles.Downloading)
let received_bytes = 0;
let total_bytes = 0;

// eslint-disable-next-line
console.log('-----------------')
// eslint-disable-next-line
console.log(url, path)
console.log('-----------------')

var req = request(
    {
        method: 'GET',
        uri: url,
        headers: {
            Authorization: `token ${options.gitRepoToken}`,
            'Accept': 'application/octet-stream',
            'User-Agent': 'request module',
        },
        //encoding: null
    }
);

// eslint-disable-next-line
console.log(req)

var out = fs.createWriteStream(path);
req.pipe(out);

req.on('response', data => {
    // eslint-disable-next-line
    console.log(data.headers, data)
    total_bytes = parseInt(data.headers['content-length']);
});

req.on('data', chunk => {
    received_bytes += chunk.length;
    showProgress(received_bytes, total_bytes);
});

req.on('end', () => {
    Install(options)
});}

url 变量等于：https: //github.com/SolberLight/PRIVATE_REPO_NAME/releases/download/1.0/MY_ZIP_NAME.zip

看起来我总是得到 9 字节的内容大小并带有“未找到”响应，所以我猜测我的标头不正确？

感谢您的帮助 ！

编辑 1：取得了一些进展，但现在看来斑点的大小不正确

 (async () => {
    //get latest release
    var response = await axios.get(
        `https://api.github.com/repos/${repoWithOwner}/releases/latest`,
        {
            headers: authHeaders,
        }
    );
    var assets = response.data.assets;
    for (var i = 0; i < assets.length; i++) {
        console.log(assets[i].url);
        response = await axios({
            method: "get",
            url: assets[i].url,
            responseType: "blob",
            headers: {
                //Accept: "application/octet-stream",
                ...authHeaders,
            },
        });
        // eslint-disable-next-line
        console.log(response.data, path)

        let reader = new FileReader()
        reader.onload = function() {
            if (reader.readyState == 2) {
                var buffer = new Buffer(reader.result)
                console.log(`Saving ${JSON.stringify({ fileName: 'myfile.zip', size: response.data.size })}`)
                outputFile(path, buffer, err => {
                    if (err) {
                        // eslint-disable-next-line
                        console.log(err.message)
                    } else {
                        // eslint-disable-next-line
                        console.log(path)
                    }
                })
            }
        }
        reader.readAsArrayBuffer(response.data)
    }
})();

您可以使用此处记录的下载存储库存档 (zip) 端点

\n

考虑以下因素：

\n

\n

• 您将对 /repos/{owner}/{repo}/zipball/{ref} 执行 GET 请求

  \n
\n

• 第一个请求将发送重定向（302响应），您需要正确遵循重定向，在这种情况下，由于您使用的是axios，因此您需要手动处理它。响应将包含您将在以下请求中使用的zipball_url 。

  \n
\n

• 由于您正在下载私人存储库版本，因此请考虑这些链接是临时的，并会在五分钟后过期。

  \n
\n

• 第一个请求接受用户或安装令牌（如果您将 API 作为 GitHub 应用程序使用）。在此处详细了解 GitHub 应用程序和 GitHub OAuth 应用程序之间的区别

  \n
\n

• 如果您使用的是 GitHub OAuth 应用程序，请确保您具有存储库范围，对于 GitHub 应用程序，请确保您具有内容权限
