我正在开发一个 ASP.NET Core 2.2 网站,用户需要在其中登录然后使用它。
将AccountController在我的网站调用另一个ASP.NET核心的WebAPI(带[AllowAnonymous]属性),以得到用户名和密码令牌的JWT。
除了AccountController网站内的所有控制器都将具有[Authorize("Bearer")]检查用户是否已获得授权的属性。
我的 WebApi 也会有其他需要 的控制器[Authorize("Bearer")],因此在发出 http 请求时将从网站传递 JWT 令牌。在WebApi项目中查看下面配置的Startup.cs>ConfigureServices()方法文件:
services.AddAuthentication(options =>
{
options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
}).AddJwtBearer(options =>
{
options.SaveToken = true;
options.TokenValidationParameters = new TokenValidationParameters
{
ValidateIssuerSigningKey = true,
ValidIssuer = "ZZZZ",
ValidAudience = "ZZZZ",
IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(secretKey))
};
});
services.AddAuthorization(auth =>
{
auth.AddPolicy("Bearer", new AuthorizationPolicyBuilder()
.AddAuthenticationSchemes(JwtBearerDefaults.AuthenticationScheme)
.RequireAuthenticatedUser().Build());
});

和Configure()方法:

ASP.NET Core WebApi - 生成 JWT 令牌:
JWTToken jwt = new JWTToken();
jwt.Token = "";
jwt.Expires = DateTime.UtcNow.AddMinutes(90);
var claims = new[]
{
new Claim(ClaimTypes.UserData, UserId)
};
var key = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(privateSecretKey));
var creds = new SigningCredentials(key, SecurityAlgorithms.HmacSha256);
var token = new JwtSecurityToken(
issuer: "ZZZ",
audience: "ZZZ",
claims: claims,
expires: jwt.Expires,
signingCredentials: creds);
var tokenStr = new JwtSecurityTokenHandler().WriteToken(token);
jwt.Token = tokenStr;
return jwt;

我已经完成了生成令牌并返回 JWT 令牌的 WebApi 方法。但是我如何处理该令牌以便身份验证/授权在我的 ASP.NET Core 网站中工作。
[HttpPost]
public async Task<IActionResult> Login(LoginModel model)
{
var httpClient = _httpClientFactory.CreateClient(ConstantNames.WebApi);
var response = await httpClient.PostAsJsonAsync($"{ApiArea}/authenticate", model);
if (response.IsSuccessStatusCode)
{
var jwtToken = await response.Content.ReadAsAsync<JWTToken>();
/* --> WHAT DO I DO HERE? <-- */
}
else
{
ModelState.AddModelError("Password", "Invalid password");
model.Password = "";
return View(model);
}
return RedirectToAction("Index", "Home");
}

因此,为了使事情变得复杂,我的项目概述如下:
ASP.NET Core 网站- 具有登录页面和其他控制器,对数据表和表单进行 ajax 调用,必须经过授权 ASP.NET Core WebApi - 生成 JWT 令牌,并具有其他必须经过授权的 api 调用的方法
我如何告诉网站,如果用户未获得授权,则转到我的/Account/Login页面?
这个过程是否正确,如果不是,我是否仍然需要添加身份并为网站以不同的方式执行此操作?
如果您的 ASP.NET Core 网站和 ASP.NET Web API 是两个不同的网站:
Authorization : Bearer {access_token}. 或者注册一个OnMessageReceived处理程序,如果你想通过 cookie/querystring 发送它我不确定您的身份验证如何。
假设您选择对 ASP.NET Core 网站使用 cookie,请确保您已设置 LoginPath = "/Account/Login";
// the Startup::ConfigureServices of your ASP.NET Core Website
services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
.AddCookie(o => {
o.LoginPath = "/Account/Login";
});

然后按照Camilo Terevinto 的建议,您需要让用户登录:
[HttpPost]
public async Task<IActionResult> Login(LoginModel model)
{
var httpClient = _httpClientFactory.CreateClient(ConstantNames.WebApi);
var response = await httpClient.PostAsJsonAsync($"{ApiArea}/authenticate", model);
if (response.IsSuccessStatusCode)
{
var jwtToken = await response.Content.ReadAsAsync<JWTToken>();
var username = ...
var others = ...
var claims = new List<Claim>
{
new Claim(ClaimTypes.Name, username),
// add other claims as you want ...
};
var iden= new ClaimsIdentity( claims, CookieAuthenticationDefaults.AuthenticationScheme);
var principal = new ClaimsPrincipal(iden);
await HttpContext.SignInAsync( CookieAuthenticationDefaults.AuthenticationScheme, principal);
return Redirect("/")
}
else
{
ModelState.AddModelError("Password", "Invalid password");
model.Password = "";
return View(model);
}
return RedirectToAction("Index", "Home");
}
