如何在注册过程中将User.Id值添加到Custom.UserId? [英] How can I add User.Id value to Custom.UserId during registration?
问题描述
我将拥有一个预先填充的数据库，该数据库将具有从另一台服务器推送到该数据库的信息.列之一将是UserId，并将与ApplicationUser一对一关系.我正在使用Identity Core来确保安全性.
I will have a prepopulated Database that will have information pushed to it from another server. One of the columns will be UserId and will have a one to one relationship with ApplicationUser. I am using Identity Core for security.
如何在注册过程中收集AspNetUser.Id并将其推送到另一个表EmpProflie.UserId值?
How do I collect the AspNetUser.Id during the registration process and push it to the other table EmpProflie.UserId value?
我认为在OnPostAsync的if(result.Succeeded)期间，应该在发送电子邮件确认后的某处调用以下代码来获取AspNetUser Id的值.
显然是关于var userId的错误
I think during OnPostAsync's if(result.Succeeded) I should be able to get the value of the AspNetUser Id by calling the following code somewhere after the email confirmation is sent.
Error obviously on var userId
var aspUserId = _userManager.Users.Select(e=>e.Id);
var userId = _context.EmpProfile.Add(aspUserId).Entity.UserId;
我不确定如何将该值推送给正在注册的当前用户
这样一来，它就可以派上用场了. _context.EmpProfile.UserId?????
I'm not sure how to push that value to the current user who is registering
so that it's assigned off the bat. _context.EmpProfile.UserId?????
这是完整的方法:
public async Task<IActionResult> OnPostAsync(string returnUrl = null)
{
returnUrl = returnUrl ?? Url.Content("~/");
ExternalLogins = (await _signInManager.GetExternalAuthenticationSchemesAsync()).ToList();
var isInDb =
_context.EmpProfile.Any(e => e.Email.ToLower() == Input.Email.ToLower());
if (ModelState.IsValid && isInDb)
{
var user = new IdentityUser { UserName = Input.Email, Email = Input.Email };
var result = await _userManager.CreateAsync(user, Input.Password);
if (result.Succeeded)
{
_logger.LogInformation("User created a new account with password.");
var code = await _userManager.GenerateEmailConfirmationTokenAsync(user);
code = WebEncoders.Base64UrlEncode(Encoding.UTF8.GetBytes(code));
var callbackUrl = Url.Page(
"/Account/ConfirmEmail",
pageHandler: null,
values: new { area = "Identity", userId = user.Id, code = code, returnUrl = returnUrl },
protocol: Request.Scheme);
await _emailSender.SendEmailAsync(Input.Email, "Confirm your email",
$"Please confirm your account by <a href='{HtmlEncoder.Default.Encode(callbackUrl)}'>clicking here</a>.");
var userId = _userManager.Users.Select(e => e.Id);
var userId = _context.EmpProfile.Add(aspUserId).Entity.UserId; <--- ERROR
if (_userManager.Options.SignIn.RequireConfirmedAccount)
{
return RedirectToPage("RegisterConfirmation", new { email = Input.Email, returnUrl = returnUrl });
}
else
{
await _signInManager.SignInAsync(user, isPersistent: false);
return LocalRedirect(returnUrl);
}
}
foreach (var error in result.Errors)
{
ModelState.AddModelError(string.Empty, error.Description);
}
}
// If we got this far, something failed, redisplay form
return Page();
}
更新
我尝试了以下操作，但是我不确定如何仅设置UserId值.
I have tried the following but I'm not sure how to set just the UserId value.
就像用户@Fei Han在下面建议的那样，我发现如何通过昨晚的stackoverflow来获取aspnet User.Id.
Like user @Fei Han suggested below, I found how to get aspnet User.Id looking through stackoverflow last night.
var aspUserId = user.Id;
if (aspUserId != null)
{
var ownerId = new EmpInfo
{
UserId = aspUserId
};
_context.Update(ownerId);
_context.SaveChanges();
}
但是，当我设置该值时，这将覆盖我所有的现有数据.我 am 可以将UserId设置为正确的值.我只是现在还不知道如何只设置/更新ONE属性而不覆盖其他所有属性.
However, this is overwriting all of my existing data when I set the value. I am getting the UserId to value set properly though. I just can't figure out as of yet how to only set/update the ONE property without overwriting all the others.

如果调试代码，您会发现在创建新的IdentityUser对象时，Id属性被初始化以形成新的GUID字符串值，如下所示.
If you debug the code, you would find that the Id property is initialized to form a new GUID string value while you create a new IdentityUser object, like below.
因此，您可以修改以下代码以获取新用户的ID，然后将其存储或更新到EmpProfile表.
So you can modify the code as below to get new user's Id, then store or update to your EmpProfile table.
public async Task<IActionResult> OnPostAsync(string returnUrl = null)
{
returnUrl = returnUrl ?? Url.Content("~/");
ExternalLogins = (await _signInManager.GetExternalAuthenticationSchemesAsync()).ToList();
if (ModelState.IsValid)
{
var user = new IdentityUser { UserName = Input.Email, Email = Input.Email };
var result = await _userManager.CreateAsync(user, Input.Password);
if (result.Succeeded)
{
//get new registered user's id
var user_id = user.Id;
//store or update with new reger user's id in EmpProfile table
//...

要使用aspUserId更新EmpProfile UserId并保留到数据库，您可以参考以下代码段.
To update EmpProfile UserId with aspUserId and persist to the database, you can refer to the following code snippet.
var Emp = _context.EmpProfile.Where(e => e.Email.ToLower() == Input.Email.ToLower()).FirstOrDefault();
if (ModelState.IsValid && Emp != null)
{
var user = new IdentityUser { UserName = Input.Email, Email = Input.Email };
var result = await _userManager.CreateAsync(user, Input.Password);
if (result.Succeeded)
{
//get new registered user's id
var aspUserId = user.Id;
//store or update with new reger user's id in EmpProfile table
//...
if (aspUserId != null)
{
Emp.UserId = aspUserId;
//By default, queries that return entity types are tracking
//can make changes to those entity instances and have those changes persisted by SaveChanges()
_context.SaveChanges();
}
