Azure AD B2C 更新用户登录名导致错误

Question

当我尝试更新 SignInNames 的列表时，出现错误： Resource <EMAIL ADDRESS> does not exist or one of its queried reference-property objects are not present.

var currentUser = await GetUserByUserNameAsync(userId); // this gets the user
var signinNames = currentUser.SignInNames.ToList();
signinNames.Add(new SignInName
{
   Type = "emailAddress",
   Value = newEmailaddress
});
var data = new B2CChangeEmailAddressData()
{
    SignInNames = signinNames
};
var response = await _graphApi.SendAsync(new HttpMethod("PATCH"), $"users/{userId}", null, data);

然后 returns 错误。 我使用可比较的代码来更新密码，效果很好。我是不是忽略了什么？

Answer 1

所以，我所做的是：

• 我通过登录名（电子邮件地址）找到了用户
• 我尝试使用登录名编辑用户

第一个是可能的，但第二个不是。我不得不使用 ObjectId 更新用户。所以代码应该是：

var currentUser = await GetUserByUserNameAsync(userId);
var path = $"users/{currentUser.ObjectId}";
var signinNames = new List<SignInName>();
signinNames.Add(new SignInName
{
     Type = "emailAddress",
     Value = newEmailaddress
});
var data = new B2CChangeEmailAddressData()
{
     SignInNames = signinNames
};

var response = await _graphApi.SendAsync(new HttpMethod("PATCH"), path, null, data);
