ASP.NET Core 2 API 调用被重定向 (302)答案

【问题标题】：ASP.NET Core 2 API call is redirected (302)ASP.NET Core 2 API 调用被重定向 (302)
【发布时间】：2017-09-04 11:52:52
【问题描述】：

我正在尝试迁移此项目 https://github.com/asadsahi/AspNetCoreSpa 从.net core 1.1 到 2.0 但是登录成功后出现问题。登录后，我的 GET api 调用 e。 G。到https://localhost:44331/api/profile/test 以重定向（302）结束，我不知道为什么。我收到了一个不记名令牌，看起来不错。

请求头格式：授权：Bearer [token]

[Route("api/[controller]")]
public class ProfileController : BaseController
{
    private readonly UserManager<ApplicationUser> _userManager;
    private readonly ILogger _logger;

    public ProfileController(ILoggerFactory loggerFactory, UserManager<ApplicationUser> userManager)
    {
        _logger = loggerFactory.CreateLogger<ProfileController>();
        _userManager = userManager;
    }

    [HttpGet("test")]
    public async Task<IActionResult> Test()
    {
        return  Json(ModelState.GetModelErrors());
    }
}

我想知道以下行：

用户授权失败：(null)

已经找到这个Authorization failed for user: (null) 但目前还没有答案，我认为这是 .NET Core 1 的问题。

【问题讨论】：

我也有同样的问题。 302 正试图将我带到 ~/Account/Login。然后我得到一个 404，因为该路由不存在。
升级到 asp.net core 2 后我也面临同样的问题
这个问题你解决了吗？

标签： c# asp.net-core asp.net-core-2.0 asp.net-core-identity

【解决方案1】：

当您调用 AddIdentity 时，它会添加 Cookie 身份验证，该身份验证会覆盖您预期的 JWT 不记名身份验证。解决此问题的一种方法是在设置 JWT 身份验证之前移动 AddIdentity 调用。以下是适用于我的代码：

// setup identity
services.AddIdentity<ApplicationUser, ApplicationRole>()
    .AddEntityFrameworkStores<MyMoneyDbContext>()
    .AddDefaultTokenProviders();

// setup Jwt authentication
services.AddAuthentication(options =>
{
    options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
    options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
})
.AddJwtBearer(JwtBearerDefaults.AuthenticationScheme, jwtBearerOptions =>
{
    jwtBearerOptions.TokenValidationParameters = new TokenValidationParameters
    {
        ValidateIssuerSigningKey = true,
        ...

另一种选择是使用 AddIdentityCore，但我从未尝试过。

【讨论】：

酷！！！我在重构期间更改了顺序，并开始发生 302 重定向。
天哪，你拯救了我的一天！谢谢
这是一个简单的修复，应该是答案。

【解决方案2】：

我遇到了同样的问题，为了解决这个问题，我必须在控制器的 Authorize 属性中包含身份验证方案。

在你的情况下：

[Authorize(AuthenticationSchemes = JwtBearerDefaults.AuthenticationScheme)]
[ServiceFilter(typeof(ApiExceptionFilter))]
[ResponseCache(Location = ResponseCacheLocation.None, NoStore = true)]
public class BaseController : Controller
{
    public BaseController()
    {
    }
}

【讨论】：

确实有帮助，但我想知道为什么其他人的所有示例都不需要。

【解决方案3】：

对我来说，它与跨域资源共享 (CORS) 有关。我在 Azure 的应用服务中有一个启用了 CORS 的 API。当我将 API 的调用者添加到允许的来源列表时，302 消失了。

即使我已经在我的 aspnet 核心启动代码中添加了这些来源，我也必须这样做。

【讨论】：

这不是它应该如何工作的权利吗？根据 MSFT，如果我们在 azure app 服务的 cors 部分中没有任何内容，它应该从代码中获取值。我现在也对同一点感到震惊。
