c# - ASP.Net Core MVC - 部分 View 的 Auth 上下文不同？

Question

我有一个生成 2 个局部 View 的模型。

• 一个局部 View 包含一个用于更改用户名的表单
• 另一个包含用于更改密码的表单

这两种形式都返回到 UserController 中的 POST 方法。每个部分，独立工作正常。但是，如果我更改用户名然后尝试更改密码，则 Auth Context 包含旧用户名并且我会遇到错误。

逻辑有点像这样......

更改用户名

Controller

public async Task<ActionResult> ChangeUsername(ChangeUsernameViewModel model) {
    string oldUsername = model.OldUsername;
    string newUsername = model.NewUsername;

    User user = await this.UserService.GetUserById(this.Authorization.UserId);

    if (user != null)
    {
        // Update username in DB
        User user = await this.UserService.ChangeUsername(user, newUsername);

        // Update cookie
        this._owinContext.Authentication.SignIn(this.Authorization.ToClaimsIdentity());

        // Update ViewModel
        model.OldUsername = newUsername;
        model.NewUsername = string.Empty();
    }

    return View(model);
}

服务

public async Task<User> ChangeUsername(User user, string newUsername) {
    // Blah blah blah... Code to update user with new username
    // and save changes to DB which is then followed by:

    // Change claim in Auth Context
    this._authorization.RemoveValue(MyClaimType.Username);
    this._authorization.AddValue(MyClaimType.Username, newUsername);

    // At this point, I can see that the Auth Context
    // has been updated with the new username.

    return user;
}

更改密码

Controller

public async Task<ActionResult> ChangePassword(ChangePasswordViewModel model) {
    string oldPassword = model.oldPassword;
    string newPassword = model.newPassword;

    User user = await UserService.GetUserByLogin(this.Authorization.Username, oldPassword);

    // this is where the failure occurs, so I won't 
    // bother writing out the rest.

    // this.Authorization.Username is equal to "oldUsername" 
    // that we saw in the ChangeUsername method.
}

服务中的 this._authorization 不会传回到 this.Authorization Controller 吗？this.Authorization 是否出于某种原因对于每个局部 View 都不同？

清除/重置/注销用户 session ，使用用户或数据库提供的新数据重新加载 session 数据信息
