Dynamics crm CrmServiceClient始终返回空的组织服务

我有以下代码连接到Dynamics 365 Online组织。它在

orgService.Execute（new WhoAmIRequest（））上引发空引用异常和错误日志位于代码下方。我已经在两台使用不同控制台应用程序的机器上尝试过了。我已经尝试了8.2和8.0 SDK DLL。如果我使用
CrmConnection
和7.x SDK DLL重写这个，一切都会正常工作。我可以使用相同的凭据浏览到组织（剪切和粘贴以确保没有输入错误）

连接字符串格式取自以下示例：

使用Office 365的命名帐户


基本代码

var connectionString=@“Url=https://ORGNAME.crm.dynamics.com；用户名=username@ORGNAME.onmicrosoft.com；Password=43JF##$j#@Ha；Authype=Office365；“；
var client=新的CrmServiceClient（connectionString）；
var orgService=（IOOrganizationService）client.OrganizationWebProxyClient？？client.OrganizationServiceProxy；
Execute（new WhoAmIRequest（））；

错误日志输出：

您是否尝试过将参数直接传递给CrmServiceClient而不是连接字符串

我可以使用以下方法成功连接到Dynamics365

public CrmServiceClient(string crmUserId, SecureString crmPassword, string crmRegion, string orgName, bool useUniqueInstance = false, bool useSsl = false, OrganizationDetail orgDetail = null, bool isOffice365 = false);

我是这样申请的

var pwd = ConvertToSecureString("userpassword");
CrmServiceClient client = new CrmServiceClient("user@mail.com", pwd, "NorthAmerica", "orgname", isOffice365: true);

下面是将密码转换为安全字符串的方法

private System.Security.SecureString ConvertToSecureString(string password)
{
    if (password == null)
        throw new ArgumentNullException("missing pwd");

    var securePassword = new System.Security.SecureString();
    foreach (char c in password)
        securePassword.AppendChar(c);

    securePassword.MakeReadOnly();
    return securePassword;
 }

根据微软的最新建议，我们不应该使用“AuthType=Office365”


我们可以使用应用程序帐户（客户端ID和密钥）生成令牌和访问Dynamics CRM组织服务。但是如果您想使用用户ID&PWD，那么就使用（AuthType=OAuth）

示例代码：

字符串连接string=“AuthType=OAuth；Url=”https://******.crm.dynamics.com'；用户名=””；密码=””；AppId=51f81489-12ee-4a9e-aaae-a2591f45987d；重定向URI=app://58145B91-0C36-4500-8554-080854F2AC97；LoginPrompt=Never”

ServicePointManager.SecurityProtocol=SecurityProtocolType.Tls12

CrmServiceClient CrmServiceClient=新的CrmServiceClient（connectionString）；
WhoAmIResponse WhoAmIResponse=crmServiceClient.Execute（new WhoAmIRequest（））为WhoAmIResponse

注意：在尝试使用Azure函数时，我遇到以下错误：

从身份验证上下文请求令牌时出错需要非空权限
出现一个或多个错误。=>发送请求时出错。=>基础连接已关闭：发送时发生意外错误。=>无法从传输连接读取数据：远程主机强制关闭了现有连接。=>从身份验证上下文请求令牌的远程hostERROR强制关闭了现有连接
CurrentAccessToken='crmServiceClient.CurrentAccessToken'引发了类型为'System.NullReferenceException'的异常
只需使用一行代码即可轻松解决这些问题：ServicePointManager.SecurityProtocol=SecurityProtocolType.Tls12

请让我知道你是否面临任何其他问题

我出错了

Unable to login to Dynamics CRM, Error was :                    
Data[0] = "The provided uri did not return any Service Endpoints!   

我在尝试使用AuthType=ClientSecret的连接字符串连接到Dynamics时收到此错误。之前，我使用用户名和密码以及表单的连接字符串成功连接

"Url={dynamicsConnectionString};Username={username};Password={password};AuthType=Office365;"

连接字符串已更改为具有以下格式：

"AuthType=ClientSecret;RequireNewInstance=false;Url={CrmDynamicsPrivatePrimaryConnection};ClientId={CrmDynamicsPrivateClientId};ClientSecret={CrmDynamicsPrivateClientSecret};LoginPrompt=Never;"

出现此错误是因为我使用的是过期版本的Microsoft.CrmSdk.XrmTooling.CoreSassembly

。我使用的是版本

9.0.2.27

，根据一份网络报告，连接ClientSecret需要版本

9.1.0.13

。我使用NuGet更新到版本

9.1.0.68

，动态连接工作正常。

该方法当然有效，谢谢发布。它仍然无法解决SDK中记录的连接字符串方法无法工作的原因。我想弄清楚我是做错了什么，还是一个bug。在我的真实应用程序中，问题变成了我更喜欢从配置文件中获取连接字符串，因为这样就不必知道我正在建立什么类型的连接并传递正确的参数。我在

连接字符串中有一个类型。应该是authtype，我有authtype。这就是说，你的回答实际上让我明白了这一点，值得称赞-将身份验证类型声明为显式参数有助于消除此问题。很高兴你找到了根本原因：）。。顺便说一句，这是一种很难在一开始就注意到的打字错误。这对我来说是“ServicePointManager.SecurityProtocol=SecurityProtocolType.Tls12；”。谢谢
