【问题描述】：

我的要求是将我的数据库记录同步到 Dynamic 365 并对用户进行身份验证。

我正在尝试使用此代码，但它没有帮助我，请帮助我连接并解决它

string api = "https://ujwl.api.crm8.dynamics.com/api/data/v9.0";

AuthenticationParameters ap = AuthenticationParameters.CreateFromResourceUrlAsync(new Uri(api)).Result;

var creds = new ClientCredential("xxx", "xxx");


AuthenticationContext authContext = new AuthenticationContext(ap.Authority);

var token = authContext.AcquireTokenAsync(ap.Resource, creds).Result.AccessToken;

using (HttpClient httpClient = new HttpClient())
{
httpClient.Timeout = new TimeSpan(0, 2, 0);
httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);

HttpResponseMessage response = await httpClient.GetAsync("https://ujwl.api.crm8.dynamics.com/api/data/v9.0/accounts?$top=2");
}

我无法验证用户身份，也无法从服务器获取数据。这种方法是否正确，或者我需要采用不同的方法。

这是我通过挖掘 Microsoft Docs 得到的上述问题的解决方案

string resource = "https://ujwl.crm8.dynamics.com/";
string clientId = "aaaa1111-xxxx-yyyy-zzzz-2222bbbbc692";
string redirectUrl = "https://localhost:44345/";

AuthenticationContext authContext = new AuthenticationContext("https://login.windows.net/common", false);
AuthenticationResult result = authContext.AcquireToken(resource, clientId, new Uri(redirectUrl));
HttpResponseMessage response = null;
using (HttpClient httpClient = new HttpClient())
{
    ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls;
    httpClient.Timeout = new TimeSpan(0, 2, 0);
    httpClient.BaseAddress = new Uri("https://ujwl.crm8.dynamics.com/");
    httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", result.AccessToken);

    response = await httpClient.GetAsync("https://ujwl.api.crm8.dynamics.com/api/data/v9.0/contacts");
}

【解决方案2】：

我只在本地完成，所以我可能是错的......但在我看来你可以/应该使用 MS c# API。命名空间为Microsoft.Xrm.Sdk，可以在MS页面下载。

请注意，以下代码是部分代码，对于内部部署，可能在线会有不同的连接字符串/参数。

        private IOrganizationService _orgService = null;

        public CrmHelper(string serverHost, int port, string orgName, bool usarSSL, string dominio, string usuario, string password, bool claims)
        {
            /* Nomenclatura usando CLAIMS
 * ServiceUri=https://[server:puerto]/[NombreOrganizacion];
 * AuthType=IFD;
 * Domain=[Dominio];
 * UserName=[Dominio]\[usuario];
 * Password=[Password];
 * LoginPrompt=Never;
 * Organization=[NombreOrganizacion] */

            /* Nomenclatura sin usar CLAIMS: 
 * Url=http://[direccionIP]/[NombreOrganizacion]; 
 * Domain=[Dominio]; 
 * Username=[usuario]; 
 * Password=[Password]; 
 * authtype=AD 
             */
            string formato = claims ? @"ServiceUri={0}://{1}{2}/{3};AuthType=IFD;Domain={4};UserName={4}\{5};Password={6};LoginPrompt=Never;Organization={3}" : @"Url={0}://{1}{2}/{3}; Domain={4}; Username={5}; Password={6}; authtype=AD";
            string connectionString = string.Format(formato, (usarSSL) ? "https" : "http", serverHost, (port == 80) ? "" : ":" + port.ToString(), orgName, dominio, usuario, password);
            CrmServiceClient conn = new Xrm.Tooling.Connector.CrmServiceClient(connectionString);

            // Cast the proxy client to the IOrganizationService interface.
            _orgService = (IOrganizationService)conn.OrganizationWebProxyClient != null ? (IOrganizationService)conn.OrganizationWebProxyClient : (IOrganizationService)conn.OrganizationServiceProxy;

            if (_orgService == null || !conn.IsReady)
            {
                throw new ArgumentException("No se ha podido conectar al CRM con los parametros facilitados");
            }
        }
