将WebApp授权给ADFS以访问Dynamics CRM Web API

Question

我有一个需要与Dynamic CRM 365 Web API交流的Web应用程序。动态CRM在ADFS上被配置为依赖方。 服务器是Windows Server 2016，所有内容都是在内部部署，而不是在Azure上。

我做什么，以获得有效的标记有以下几种：

1）在ADFS去应用程序组，并添加新的服务器应用程序，采取了客户端ID，也为我的Web应用程序客户端机密。

2）在Active Directory中添加新的新用户webAppUser

3）在CRM添加该用户为应用用户与应用程序ID，当我注册了我的网络我刚才得到了客户端ID应用程序到ADFS。还创建了一个新的角色，具有完全权限的实体帐户，并将此角色分配给此应用程序用户

4）我使用下面的代码来检索不记名令牌并将其添加到我的HttpClient授权标头。

public class CrmWebApiClient 
{ 
    private HttpClient _httpClient; 

    public CrmWebApiClient() 
    { 
     _httpClient = new HttpClient(); 
     _httpClient.BaseAddress = new Uri("https://crmbaseaddress.com");    
    } 

    internal async Task Initialize() 
    { 
     try 
     {    
      var authority = "https://adfsServerUrl/adfs/"; 
      var authContext = new AuthenticationContext(authority,false); 
      var credentials = new ClientCredential(clientID,clientSecret); 

      var authResult = await authContext.AcquireTokenAsync("https://crmbaseaddress.com", credentials); 

      _httpClient.DefaultRequestHeaders.Authorization = 
       new AuthenticationHeaderValue("Bearer", authResult.AccessToken); 
     } 
     catch (Exception ex) 
     { 
      var error = ex; 
     } 

    } 

    internal async Task<string> GetValuesAsync() 
    { 
     var result = string.Empty; 
     try 
     { 
      result = await _httpClient.GetStringAsync("api/data/v8.1/accounts"); 
     } 
     catch (Exception ex) 
     { 
      var error = ex; 
     } 

     return result; 
    } 
} 

5）我设法得到一个令牌，但是当我打电话给CRM的Web Api时，我仍然得到401 Unauthorized。

你能帮我吗？我在正确的道路上吗？我应该做更多的事吗？

最后我不得不使用系统的用户和使用的代码，以获得有效令牌发送它的凭证在我的OAuth请求如下：

namespace TestApp.App_Start { 
public class CrmWebApiClient 
{ 
    private HttpClient _httpClient; 

    public CrmWebApiClient() 
    {  
     _httpClient = new HttpClient(); 
     _httpClient.BaseAddress = new Uri("https://crmUrl"); 
     _httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); 
     _httpClient.DefaultRequestHeaders.Add("OData-MaxVersion","4.0"); 
     _httpClient.DefaultRequestHeaders.Add("OData-Version", "4.0"); 
    } 

    internal async Task Initilize() 
    { 
     try 
     { 

      var tokenClient = new HttpClient();    
      var content = new FormUrlEncodedContent(new[] { 
       new KeyValuePair<string,string>("client_id",_clientID), 
       new KeyValuePair<string,string>("client_secret",_clientSecret), 
       new KeyValuePair<string,string>("resource",_urlOfResource), 
       new KeyValuePair<string,string>("username",_usernameOfSystemUser), 
       new KeyValuePair<string,string>("password",_passwordOfSystemUser), 
       new KeyValuePair<string,string>("grant_type","password"), 
      }); 
      var res = tokenClient.PostAsync("https://adfsUrl/adfs/oauth2/token", content); 
      var respo = res.Result.Content.ReadAsStringAsync().Result; 
      var accesstoken = JObject.Parse(respo).GetValue("access_token").ToString(); 

      _httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", accesstoken); 

     } 
     catch (Exception ex) 
     { 
      Trace.WriteLine($"Exception when requesting the bearer token from ADFS: {ex.Message} - {ex.InnerException?.Message}"); 
     } 

    } 

    internal async Task<string> GetAccountsAsync() 
    { 
     var result = string.Empty; 
     try 
     { 
      result = _httpClient.GetStringAsync("/api/data/v8.0/accounts").Result; 

     } 
     catch (Exception ex) 
     { 
      Trace.WriteLine($"Exception when calling the CRM api: {ex.Message} - {ex.InnerException?.Message}"); 
     } 
     return result; 
    } 
} 
} 


// Use the above class like that 
var httpClient = new CrmWebApiClient(); 
httpClient.Initilize().Wait(); 
var result = httpClient.GetAccountsAsync().Result;
