我正在尝试使用 youtube api 的 v3 上传文件，而不使用 c# 库。我真的不能使用图书馆，因为我正在制作自己的图书馆，允许我使用一些常见的 api（youtube、vimeo、facebook 等）
我已经获得了访问令牌和刷新令牌，这很好。现在我需要使用此处定义的 youtube 可恢复上传来上传文件：
https://developers.google.com/youtube/v3/guides/using_resumable_upload_protocol
但由于某种原因，我的代码返回 401 Unauthorized 错误，但我不明白为什么。这是我创建请求的代码：
private void CreateUploadRequest(SynchronisedAsset asset)
{
var endPoint = api.ApiUrl + "/videos?uploadType=resumable&part=snippet&key=" + api.Tokens.ConsumerKey; // read for the different ways to interact with videos https://developers.google.com/youtube/v3/docs/#Videos
var maxSize = 68719476736; // 64 gig
try
{
var location = CompanyProvider.GetUploadLocation(this.baseUploadDirectory, companyId, FileType.Asset);
var filePath = System.IO.Path.Combine(location, asset.FileName);
using (var data = new FileStream(filePath, FileMode.Open))
{
if (maxSize > data.Length && (asset.MimeType.ToLower().StartsWith("video/") || asset.MimeType.ToLower().Equals("application/octet-stream")))
{
var json = "{ \"snippet\": { \"title\": \"" + asset.FileName + "\", \"description\": \"This is a description of my video\" } }";
var buffer = Encoding.ASCII.GetBytes(json);
var request = WebRequest.Create(endPoint);
request.Headers[HttpRequestHeader.Authorization] = string.Format("Bearer {0}", api.Tokens.AccessToken);
request.Headers["X-Upload-Content-Length"] = data.Length.ToString();
request.Headers["X-Upload-Content-Type"] = asset.MimeType;
request.ContentType = "application/json; charset=UTF-8";
request.ContentLength = buffer.Length;
request.Method = "POST";
using (var stream = request.GetRequestStream())
{
stream.Write(buffer, 0, (int)buffer.Length);
}
var response = request.GetResponse();
}
}
}
catch (Exception ex)
{
eventLog.WriteEntry("Error uploading to youtube.\nEndpoint: " + endPoint + "\n" + ex.ToString(), EventLogEntryType.Error);
}
}
api.ApiUrl 是https://www.googleapis.com/youtube/v3。我不确定是否需要密钥，它没有在文档中显示，但我添加了它以查看是否可以解决我的未经授权的问题。另外，我想如果没有密钥，它怎么知道要上传到哪个帐户？
谁能看到我的代码有什么问题？
任何帮助将不胜感激。

经过一段时间整理后，我现在添加了一些代码，在尝试上传之前检查 youtube 凭据。这是通过以下代码完成的：
public string GetAuthorizeApplicationUrl()
{
var sb = new StringBuilder();
var dictionary = new Dictionary<string, string>
{
{"client_id", Tokens.ConsumerKey},
{"redirect_uri", callbackUrl},
{"response_type", "code"},
{"scope", "https://www.googleapis.com/auth/youtube https://www.googleapis.com/auth/youtube.upload https://www.googleapis.com/auth/youtubepartner"},
{"approval_prompt", "force"},
{"access_type", "offline"},
{"state", ""}
};
sb.Append(requestTokenUrl);
foreach (var parameter in dictionary)
{
var query = (sb.ToString().Contains("?")) ? "&" : "?";
sb.Append(query + parameter.Key + "=" + parameter.Value);
}
return sb.ToString();
}
这段代码负责构建允许我们请求用户访问的 URL。
使用返回到我们返回 URL 的代码，我们称之为这段代码：
public void RequestAccessToken(string code)
{
var dictionary = new Dictionary<string, string>
{
{"code", code},
{"client_id", Tokens.ConsumerKey},
{"client_secret", Tokens.ConsumerSecret},
{"redirect_uri", callbackUrl},
{"grant_type", "authorization_code"}
};
var parameters = NormalizeParameters(dictionary);
var resultString = "";
using (var wc = new WebClient())
{
//wc.Headers[HttpRequestHeader.Host] = "POST";
wc.Headers.Add("Content-Type", "application/x-www-form-urlencoded");
resultString = wc.UploadString(requestAccessTokenUrl, parameters);
}
var json = JObject.Parse(resultString);
Tokens.AccessToken = json["access_token"].ToString();
Tokens.RefreshToken = (json["refresh_token"] != null) ? json["refresh_token"].ToString() : null;
Tokens.Save(companyId);
}
现在因为我们已经将我们的应用程序声明为离线，所以当我们进行任何 api 调用时，我们可以使用以下代码：
public bool CheckAccessToken()
{
try
{
RefreshToken(); // Get and store our new tokens
return true;
}
catch
{
return false;
}
}
private void RefreshToken()
{
var dictionary = new Dictionary<string, string>
{
{"refresh_token", Tokens.RefreshToken},
{"client_id", Tokens.ConsumerKey},
{"client_secret", Tokens.ConsumerSecret},
{"grant_type", "refresh_token"}
};
var parameters = NormalizeParameters(dictionary);
var resultString = "";
using (var wc = new WebClient())
{
//wc.Headers[HttpRequestHeader.Host] = "POST";
wc.Headers.Add("Content-Type", "application/x-www-form-urlencoded");
resultString = wc.UploadString(requestAccessTokenUrl, parameters);
}
var json = JObject.Parse(resultString);
Tokens.AccessToken = json["access_token"].ToString();
Tokens.Save(companyId);
}
在我的 Windows 服务中，我有以下代码：
public void SynchroniseAssets(IEnumerable<SynchronisedAsset> assets)
{
if (api.CheckAccessToken())
{
foreach (var asset in assets)
{
var uploadAssetThread = new Thread(() => CreateUploadRequest(asset));
uploadAssetThread.Start(); // Upload our assets at the same time
}
}
}
如您所见，它调用了上面的原始代码。当我将其解析为 json 时出现的错误是：
{
"error":{
"errors":[
{
"domain":"youtube.header",
"reason":"youtubeSignupRequired",
"message":"Unauthorized",
"locationType":"header",
"location":"Authorization"
}
],
"code":401,
"message":"Unauthorized"
}
}
所以，如果有人能帮我弄清楚这意味着什么，那就太好了。
干杯，
