Node.js YouTube API 上传无法转换视频

Question

我正在尝试以编程方式将视频上传到YouTube。我选择使用 Node.js 来完成任务。

我收到XML响应以及HTTP状态代码201，并且我看到视频出现在视频管理器中，但是视频始终显示消息"失败（无法转换视频文件）"。

我可以通过YouTube自己的上传器在他们的页面上上传文件，没有问题。我只需要上传到一个帐户，所以我为该帐户设置了 OAuth2 并存储了刷新令牌。刷新令牌是硬编码的，尽管我用下面的变量替换了它。

刷新

令牌本身是否需要刷新？

我的代码：

var qs = require('querystring'),
https = require('https'),
fs = require('fs');
var p_data = qs.stringify({
client_id: myClientID,
client_secret: myClientSecret,
refresh_token: refreshTokenForAccount,
grant_type: 'refresh_token'
});
var p_options = {
host: 'accounts.google.com',
port: '443',
method: 'POST',
path: '/o/oauth2/token',
headers: {
    'Content-Type': 'application/x-www-form-urlencoded',
    'Content-Length': p_data.length,
    'X-GData-Key': myDeveloperKey
}
};
var file_path = process.argv[1] || "video.mp4";
var json = "";
var p_req = https.request(p_options, function(resp){
resp.setEncoding( 'utf8' );
resp.on('data', function( chunk ){
    json += chunk;
});
resp.on("end", function(){
    debugger;
    var access_token = JSON.parse(json).access_token;
    var title="test upload1",
        description="Second attempt at an API video upload",
        keywords="",
        category="Comedy";
    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"?>' +

        var boundary = Math.random();

        var part = '';

问题出在上传的文件上。这一行：var file_path = process.argv[1] || "video.mp4";应该var file_path = process.argv[2] || "video.mp4";

注意 argv[1] 是正在运行的脚本的绝对路径，argv[2] 是传递给脚本的第一个命令行参数。

当然，YouTube将无法转换"视频"，它根本不是视频，而是正在运行的脚本。
