c# - 使用 UCWA api 并在尝试通过代码 C# 连接时出现错误

Question

我正在使用 UCWA api 创建 Lync session URL，但我在某个步骤中遇到错误，

它与 LYNC 有关，因此试图弄清楚如何解决。我的代码是

string url_00   = ucwaMsRtcOAuth;   
var authDic_00  = new Dictionary<string, string>();  

authDic_00.Add("grant_type", "password");  
authDic_00.Add("username", String.Format("{0}\\{1}", ucwaAdDomain, ucwaAdUser));  
authDic_00.Add("password", ucwaAdPassword);  

httpClient.DefaultRequestHeaders.Remove("Accept");  
httpClient.DefaultRequestHeaders.Add("Accept", "application/vnd.microsoft.com.ucwa+xml");  

var res_00 = await httpClient.PostAsync(url_00, new FormUrlEncodedContent(authDic_00));  

string res_00_request   = res_00.RequestMessage.ToString();  
string res_00_headers   = res_00.Headers.ToString();  
string res_00_status    = res_00.StatusCode.ToString();  
var res_00_content      = await res_00.Content.ReadAsStringAsync();  

最后 4 个变量的输出为

res_00.RequestMessage

Method: POST, RequestUri: 'https://lynceu1webint.MYCOMPANYNAME.com/WebTicket/oauthtoken', 
Version: 1.1, Content: System.Net.Http.FormUrlEncodedContent, Headers:
{
  Accept: application/vnd.microsoft.com.ucwa+xml
  Content-Type: application/x-www-form-urlencoded
  Content-Length: 72
}

res_00.标题

BadRequest

res_00.Content

{"error":"invalid_grant"}

Answer 1

您看到该错误响应有几个潜在原因:

• 不正确的域\用户名组合
• 密码不正确
• 授权字符串不正确

如果您打算将域和密码与密码 grant_type 一起使用，请确保您的授权字符串类似于:

grant_type=password&domain\username&password=*******

如果这仍然不起作用，您可能需要提供用于将该用户登录到桌面版 Skype for Business 的 SIP/帐户。这个授权字符串看起来像:

grant_type=password&username@domain.com&password=*******
