ADAL . net Core内核包不支持UserPasswordCredential
本文关键字:不支持 UserPasswordCredential 内核 net Core ADAL | 更新日期: 2023-09-27 18:06:24
In ADAL。净3。UserPasswordCredential是在2.x的UserCredential之上引入的。但相同的UserPasswordCredential不暴露在相同的核包下的。net核心?
UserCredential类只有一个属性UserName
namespace Microsoft.IdentityModel.Clients.ActiveDirectory
{
//
// Summary:
// Credential used for integrated authentication on domain-joined machines.
public class UserCredential
{
//
// Summary:
// Constructor to create user credential. Using this constructor would imply integrated
// authentication with logged in user and it can only be used in domain joined scenarios.
public UserCredential();
//
// Summary:
// Constructor to create credential with client id and secret
//
// Parameters:
// userName:
// Identifier of the user application requests token on behalf.
public UserCredential(string userName);
//
// Summary:
// Gets identifier of the user.
public string UserName { get; }
}
}
由于UserPasswordCredential在。net Core中不可用,UserCredential只需要一个参数username,如何在。net Core中输入用户的密码并实现下面的代码?
authContext.AcquireTokenAsync(WebAPIResourceId, ClientId, userPasswordCredential);
我正在使用ADAL 3.13.4版本,特别是在。net Core 1.0版本
要使用资源所有者密码凭证授予流来获取Azure AD的访问令牌,我们可以使用HttpClient直接调用http请求。这里有一个例子供你参考:
HttpClient client = new HttpClient();
string tokenEndpoint = "https://login.microsoftonline.com/{tenantId}/oauth2/token";
var body = "resource={resourceUrl}&client_id={clientId}&grant_type=password&username={userName}&password={password}";
var stringContent = new StringContent(body, Encoding.UTF8, "application/x-www-form-urlencoded");
var result=await client.PostAsync(tokenEndpoint, stringContent).ContinueWith<string>((response) =>
{
return response.Result.Content.ReadAsStringAsync().Result;
});
JObject jobject = JObject.Parse(result);
var token = jobject["access_token"].Value<string>();
您是正确的,UserPasswordCredential
不能用于。net Core, UserCredential
不再接受用户名和密码。这意味着ADAL v3不支持。net Core上的用户名/密码流。
下面是我一直在做的事情来解决这个问题。我在一个静态方法中复制了相同的行为,用于。net Core,因为UserPasswordCredential类丢失了。这是基于对。net版本中使用UserPasswordCredential类时所发生的情况的跟踪。由于。net DLL似乎被混淆了,这是捕获它所做的事情的最佳尝试。

快进到2020年,使用ADAL 3.19.8,您应该能够使用ClientCredential类进行AAD身份验证。当与D365 CRM web API集成时,它为我工作。我在下面的博文中记录了我的经历。
