我正在使用 Asp.Net 身份。当我想使用电子邮件确认令牌确认新用户时，我系统地遇到无效令牌错误。
这是我的 WebApi 用户控制器：
public class UsersController : ApiController
{
private MyContext _db;
private MyUserManager _userManager;
private MyRoleManager _roleManager;
public UsersController()
{
_db = new MyContext();
_userManager = new MyUserManager(new UserStore<MyUser>(_db));
_roleManager = new MyRoleManager(new RoleStore<IdentityRole>(_db));
}
//New user method
[HttpPost]
public async Task<HttpResponseMessage> Register([FromBody]PostUserModel userModel)
{
//New user code
...
var token = await _userManager.GenerateEmailConfirmationTokenAsync(user.Id);
var message = new IdentityMessage();
message.Body = string.Format("Hi {0} !\r\nFollow this link to set your password : \r\nhttps://www.mywebsite.com/admin/users/{1}/reset?token={2}", user.UserName, user.Id, HttpUtility.UrlEncode(token));

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {

.csrf().disable();
}

我觉得我的 app.module.ts 没问题：我正在导入 HttpClientModule 并且我已经把它放在 @NgModule 导入中，就在 BrowserModule 之后。
@NgModule({
declarations: [AppComponent,DelegationsComponent],
imports: [BrowserModule,
HttpClientModule,
GlobalModule.forRoot(),
AuthenticationModule,
DelegationModule,
routing,
FormsModule,
ReactiveFormsModule,
BrowserAnimationsModule,
ButtonModule, TableModule, DialogModule, …我编写了一个实现IEnumerable的类:
public class MyEnumerable : IEnumerable<MyClass>
{
IEnumerator IEnumerable.GetEnumerator()
{
return this.GetEnumerator();
}
public IEnumerator<MyClass> GetEnumerator()
{
//Enumerate
}
}
我想"覆盖"Where方法.我想做的是:
MyEnumerable myEnumerable = new MyEnumerable();
MyEnumerable myEnumerable2 = myEnumerable.Where(/*some predicate*/);
目前这是不可能的,因为myEnumerable.Where()返回一个IEnumerable.我想要的是myEnumerable.Where()返回一个MyEnumerable.
这有可能吗？
谢谢
