oauth-2.0 - Oauth2 Yahoo Gemini API

Question

我在调用 Yahoo Gemini API 以从我的 C# 控制台(桌面)应用程序访问 Yahoo Gemini Advertising 时遇到问题。

以下是我使用的步骤:

1. 在 https://developer.yahoo.com/apps/create/ 上创建已安装的应用程序。这给了我 {Client ID} 和 {Client Secret}。
2. https://api.login.yahoo.com/oauth2/request_auth?client_id={客户端 ID} &redirect_uri=oob&response_type=code&language=zh-cn。这将带我到我登录的雅虎登录屏幕。按同意按钮，下一个屏幕显示七个字母的授权代码(比如 nzbcns9)。我记下这个授权码。

3. 然后我使用以下代码尝试获取访问 token :

   class Program
   {
   static void Main(string[] args)
   {
       string clientId = {Client ID};
       string secret = {Client Secret};
   
       var request = WebRequest.Create(@"https://api.login.yahoo.com/oauth2/get_token");
       request.Method = "POST";
   
       SetBasicAuthHeader(request, clientId, secret);
   
       string postData = "grant_type=authorization_code&redirect_uri=oob&code=nzbcns9";
       ASCIIEncoding encoding = new ASCIIEncoding();
       byte[] byte1 = encoding.GetBytes(postData);
       request.ContentLength = byte1.Length;
       Stream dataStream = request.GetRequestStream();
       dataStream.Write(byte1, 0, byte1.Length);
       dataStream.Close();
   
       request.ContentType = "application/x-www-form-urlencoded";
       var response = request.GetResponse();
       Console.WriteLine(((HttpWebResponse)response).StatusDescription);
   }
   
   static void SetBasicAuthHeader(WebRequest request, String userName, String userPassword)
   {
       string authInfo = userName + ":" + userPassword;
       authInfo = Convert.ToBase64String(Encoding.Default.GetBytes(authInfo));
       request.Headers["Authorization"] = "Basic " + authInfo;
   }
   }
   

然后我得到

Unhandled Exception: System.Net.WebException: The remote server returned an error: (401) Unauthorized. at System.Net.HttpWebRequest.GetResponse().

我做错了什么？

我也尝试使用 Fiddler 发布相同的消息，我明白了

{"error":"invalid_request"}

我试过你的代码，对我有用的是在 Stream dataStream = request.GetRequestStream ();

所以这有效:

    string postData = "grant_type=authorization_code&redirect_uri=oob&code=nzbcns9";
    ASCIIEncoding encoding = new ASCIIEncoding();
    byte[] byte1 = encoding.GetBytes(postData);
    request.ContentLength = byte1.Length;
    request.ContentType = "application/x-www-form-urlencoded";
    Stream dataStream = request.GetRequestStream();
    dataStream.Write(byte1, 0, byte1.Length);
    dataStream.Close();
