UserManager.CreateAsync Method (TUser, String)没有提及错误。
在 Controller 中,我可以编辑以下内容:
public async Task<ObjectResult> Register(RegisterViewModel model, string returnUrl = null)
{
IDictionary<string, object> value = new Dictionary<string, object>();
value["Success"] = false;
value["ReturnUrl"] = returnUrl;
if (ModelState.IsValid)
{
var user = new ApplicationUser { Id = Guid.NewGuid().ToString(), UserName = model.Email, Email = model.Email };
var result = await _userManager.CreateAsync(user, model.Password);
if (result.Succeeded)
{
await _signInManager.SignInAsync(user, isPersistent: false);
value["Success"] = true;
}
else
{
value["ErrorMessage"] = result.Errors;
}
}
return new ObjectResult(value);
}
在客户中:
$scope.registerForm_submit = function ($event, account) {
$event.preventDefault();
if (registerForm.isValid(account)) {
// registerForm.collectData returns new FormData() which contains
// email, password, confirmpassword, agreement, returnurl...
let formData = registerForm.collectData(account),
xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function () {
if (xhttp.readyState === XMLHttpRequest.DONE) {
let data = JSON.parse(xhttp.responseText);
if (data['Success']) {
window.location = '/'
} else {
if (data['ErrorMessage'][0]['code'] === 'DuplicateUserName') {
let li = angular.element('<li/>').text(`Email ${account['email']} already exists.`);
angular.element('div[data-valmsg-summary=true] ul').html(li);
}
}
}
}
xhttp.open('POST', '/account/register');
xhttp.send(formData);
}
};
我尝试用现有的电子邮件注册新帐户并获得代码:
data['ErrorMessage'][0]['code'] === 'DuplicateUserName'
我的问题:如何检查其他情况?
最佳答案
在https://aspnetidentity.codeplex.com/SourceControl/latest#src/Microsoft.AspNet.Identity.Core/Resources.Designer.cs中找到了ASP.NET Identity中定义的错误代码-我已将它们提取到以下列表中:
ASP.NET Core Identity已定义以下代码:
因此,可能并非所有以前的错误代码都会真正显示在IdentityResult中。我都不用,所以这只是我从浏览可用源代码中学到的东西。买者自负...
似乎应该在某处记录这样的内容...
我喜欢在一个地方定义这种性质的字符串,因此我通常会执行以下操作:
public class IdentityErrorCodes
{
public const string DefaultError = "DefaultError";
public const string ConcurrencyFailure = "ConcurrencyFailure";
public const string PasswordMismatch = "PasswordMismatch";
public const string InvalidToken = "InvalidToken";
public const string LoginAlreadyAssociated = "LoginAlreadyAssociated";
public const string InvalidUserName = "InvalidUserName";
public const string InvalidEmail = "InvalidEmail";
public const string DuplicateUserName = "DuplicateUserName";
public const string DuplicateEmail = "DuplicateEmail";
public const string InvalidRoleName = "InvalidRoleName";
public const string DuplicateRoleName = "DuplicateRoleName";
public const string UserAlreadyHasPassword = "UserAlreadyHasPassword";
public const string UserLockoutNotEnabled = "UserLockoutNotEnabled";
public const string UserAlreadyInRole = "UserAlreadyInRole";
public const string UserNotInRole = "UserNotInRole";
public const string PasswordTooShort = "PasswordTooShort";
public const string PasswordRequiresNonAlphanumeric = "PasswordRequiresNonAlphanumeric";
public const string PasswordRequiresDigit = "PasswordRequiresDigit";
public const string PasswordRequiresLower = "PasswordRequiresLower";
public const string PasswordRequiresUpper = "PasswordRequiresUpper";
public static string[] All = {
DefaultError,
ConcurrencyFailure,
PasswordMismatch,
InvalidToken,
LoginAlreadyAssociated,
InvalidUserName,
InvalidEmail,
DuplicateUserName,
DuplicateEmail,
InvalidRoleName,
DuplicateRoleName,
UserAlreadyHasPassword,
UserLockoutNotEnabled,
UserAlreadyInRole,
UserNotInRole,
PasswordTooShort,
PasswordRequiresNonAlphanumeric,
PasswordRequiresDigit,
PasswordRequiresLower,
PasswordRequiresUpper
};
}
这样可以使您在用作查询的键中保持一致,最后一个字段
All
可以为您提供一个数组,您可以在必要时进行枚举。使用您的代码,您可以执行以下操作:
if(data['ErrorMessage'][0]['code'] == IdentityErrorCodes.DuplicateUserName)
{
}
等等。
