Oauth2 Yahoo Gemini API

Question

我无法通过C＃控制台（桌面）应用程序调用Yahoo Gemini API来访问Yahoo Gemini广告。

下面是步骤我用：

1. 创建于https://developer.yahoo.com/apps/create/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={Client ID} &redirect_uri=oob&response_type=code&language=en-us。这会将我带到我登录的yahoo登录屏幕。按“同意”按钮，下一个屏幕显示七字母​​授权码（例如nzbcns9）。我写下这个授权码。

3. 然后我用下面的代码，试图获得访问令牌：

   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().

我做了什么错？

我也尝试发布使用招相同的消息，我得到

{"error":"invalid_request"}

Answer 1

我想你的代码，什么工作对我来说是放线request.ContentType = "application/x-www-form-urlencoded";前Stream dataStream = request.GetRequestStream();

所以这个工作：

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();

这两种都不适合我，但是它在我改变SetBasicAuthHeader使用ISO-8859-1编码后确实有效：

static void SetBasicAuthHeader(WebRequest request, String userName, String userPassword) 
    { 
     string authInfo = userName + ":" + userPassword; 
     authInfo = Convert.ToBase64String(Encoding.GetEncoding("ISO-8859-1").GetBytes(authInfo)); 
     request.Headers[ "Authorization" ] = "Basic " + authInfo; 
    }
