Oauth2 YouTube "error" ： "invalid_request"

Question

我不明白此功能获得我的authkey有什么问题？我只会收到称为" Invalid_request"的错误，有人有任何想法吗？似乎它不了解我的要求吗？

//innk

public partial class OAuth : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
string _clientID = HttpUtility.UrlEncode("***********");
        string _clientSecret = HttpUtility.UrlEncode("******");
        string _redirectUri = "urn:ietf:wg:oauth:2.0:oob";
        string _code = HttpUtility.UrlEncode("token");
        string url = "code=" + _code + "&client_id=" + _clientID + "&client_secret=" + _clientSecret + "&redirect_uri=" + _redirectUri + "&grant_type=urn:ietf:params:oauth:grant-type:jwt-bearer";
        TcpClient client = new TcpClient("accounts.google.com", 443);
        Stream netStream = client.GetStream();
        SslStream sslStream = new SslStream(netStream);
        sslStream.AuthenticateAsClient("accounts.google.com");
        {
            byte[] contentAsBytes = Encoding.ASCII.GetBytes(url.ToString());
            StringBuilder msg = new StringBuilder();
            msg.AppendLine("POST /o/oauth2/token HTTP/1.1");
            msg.AppendLine("Host: accounts.google.com");
            msg.AppendLine("Content-Type: application/x-www-form-urlencoded");
            msg.AppendLine("Content-Length: " + contentAsBytes.Length.ToString());
            msg.AppendLine("");
            Debug.WriteLine("Request");
            Debug.WriteLine(msg.ToString());
            Debug.WriteLine(url.ToString());
            byte[] headerAsBytes = Encoding.ASCII.GetBytes(msg.ToString());
            sslStream.Write(headerAsBytes);
            sslStream.Write(contentAsBytes);
        }
        Debug.WriteLine("Response");
        StreamReader reader = new StreamReader(sslStream);
        while (true)
        {  // Print the response line by line to the debug stream for inspection.
            string line = reader.ReadLine();
            if (line == null)
                break;
            Debug.WriteLine(line);
        }
    }
}

我强烈建议您使用.NET开发并希望访问YouTube API的任何人使用官方客户端库。

如果您不希望将客户端库用于所有操作，至少，我建议您使用它为您处理OAuth 2，然后使用它在请求的Authorization标题中生成的令牌你滚动自己。
