问题描述

使用以下代码，我尝试通过 直接上传上传视频 youtube.我已经有了访问令牌 (auth_key).我很确定我发送的帖子数据不正确...

Using the following code I'm tring to upload a video youtube via direct upload. I already have the access token (auth_key). I'm pretty sure I'm sending the post data incorrectly...

function upload(auth_key, devKey, callback){

    fs.readFile('test.mp4', function(err, movie){

        var boundary = randomString();

        var xml =
            '<?xml version="1.0"?>' +
            '<entry xmlns="http://www.w3.org/2005/Atom" xmlns:media="http://search.yahoo.com/mrss/" xmlns:yt="http://gdata.youtube.com/schemas/2007">' +
            '<media:group>' + 
            '<media:title type="plain">Bad Wedding Toast</media:title>' +
            '<media:description type="plain">I gave a bad toast at my friends wedding.</media:description>' +
            '<media:category scheme="http://gdata.youtube.com/schemas/2007/categories.cat">People</media:category>' +
            '<media:keywords>toast, wedding</media:keywords>' + 
            '</media:group>' + 
            '</entry>'
        ;

        var post_data = 
            '--' + boundary + '\n' +
            'Content-Type: application/atom+xml; charset=UTF-8' + '\n' +
            xml + '\n' +
            '--' + boundary + '\n' +
            'Content-Type: video/mp4' + '\n' +
            'Content-Transfer-Encoding: binary' + '\n' +
            movie + '\n' +
            '--' + boundary + '--' + '\n'
        ;   

        var options = {
          host: 'uploads.gdata.youtube.com',
          port: 443,
          path: '/feeds/api/users/default/uploads',
          method: 'POST',
            headers: {
                'Authorization:': 'GoogleLogin auth=' + auth_key,
                'GData-Version': '2',
                'X-GData-Key': 'key=' + devKey,
                'Slug': 'test.mp4',
                'Content-Type': 'multipart/related; boundary="' + boundary + '"',
                'Content-Length': post_data.length,
                'Connection': 'close'
            }
        }

        var req = https.request(options, function(res) {
            var response = '';
          res.on('data', function(chunk) {
                response += chunk;
          });
            res.on('end', function(){
                callback(response);
            });
        });

        if(post_data){
            req.write(post_data);
        }

        req.end();

        req.on('error', function(e) {
          console.error(e);
        });

    });

}

是否因无效请求"而失败?

Is failing with "Invalid Request"?

推荐答案

您的代码中有一些错误，html 请求的语法缺少\r\n".您还应该使用 http 库和端口 80.您的 Authorization 标头无效，末尾不应包含:".而且我认为您添加数据和计算内容长度的方式也会把事情搞砸.

You have some errors in your code, the syntax of the html request is missing "\r\n". You should also use the http library and port 80. Your Authorization header is invalid, it should not contain an ":" at the end. And I think the way your are adding the data and calculating the content length also messes things up.

我已使用以下代码成功将视频上传到 youtube:

I've successfully uploaded videos to youtube with the following code:

var file_reader = fs.createReadStream(file_path, {encoding: 'binary'});
var file_contents = '';
file_reader.on('data', function(data)
{
    file_contents += data;
});
file_reader.on('end', function()
{
    var xml =
        '<?xml version="1.0"?>' +
        '<entry xmlns="http://www.w3.org/2005/Atom" xmlns:media="http://search.yahoo.com/mrss/" xmlns:yt="http://gdata.youtube.com/schemas/2007">' +
        '   <media:group>' + 
        '       <media:title type="plain">' + title + '</media:title>' +
        '       <media:description type="plain">' + description + '</media:description>' +
        '       <media:category scheme="http://gdata.youtube.com/schemas/2007/categories.cat">' + category + '</media:category>' +
        '       <media:keywords>' + keywords + '</media:keywords>' + 
        '   </media:group>' + 
        '</entry>';

    var boundary = Math.random();
    var post_data = [];
    var part = '';

    part = "--" + boundary + "\r\nContent-Type: application/atom+xml; charset=UTF-8\r\n\r\n" + xml + "\r\n";
    post_data.push(new Buffer(part, "utf8"));

    part = "--" + boundary + "\r\nContent-Type: video/mp4\r\nContent-Transfer-Encoding: binary\r\n\r\n";
    post_data.push(new Buffer(part, 'ascii'));
    post_data.push(new Buffer(file_contents, 'binary'));
    post_data.push(new Buffer("\r\n--" + boundary + "--"), 'ascii');

    var post_length = 0;
    for(var i = 0; i < post_data.length; i++)
    {
        post_length += post_data[i].length;
    }

    var options = {
      host: 'uploads.gdata.youtube.com',
      port: 80,
      path: '/feeds/api/users/default/uploads?alt=json',
      method: 'POST',
        headers: {
            'Authorization': 'GoogleLogin auth=' + auth_key,
            'GData-Version': '2',
            'X-GData-Key': 'key=' + exports.developer_key,
            'Slug': 'video.mp4',
            'Content-Type': 'multipart/related; boundary="' + boundary + '"',
            'Content-Length': post_length,
            'Connection': 'close'
        }
    }

    var req = http.request(options, function(res)
    {
        res.setEncoding('utf8');

        var response = '';
        res.on('data', function(chunk)
        {
            response += chunk;
        });
        res.on('end', function()
        {
            console.log(response);
            response = JSON.parse(response);

            callback(response);
        });
    });

    for (var i = 0; i < post_data.length; i++)
    {
        req.write(post_data[i]);
    }

    req.on('error', function(e) {
      console.error(e);
    });

    req.end();
});
