Azure Mobile Client自定义身份验证无法访问具有[授权]属性的控制器

    我正在上使用具有自定义授权的Azure Mobile Service客户端 Xamarin.Forms 站台

    登录使用 .LoginAsync("custom", user) 由于返回 MobileServiceUser 具有非null MobileAuthenticationToken 和 UserId 并自动连接 <MobileServiceClient>.CurrentUser 具有该值。

    然而,每当我尝试提出进一步的请求时(登录后立即),我都会得到一个 MobileServiceInvalidOperationException .. (Unauthorized) 当我检查 CurrentUser 价值-它仍然是一样的。

    我是不是错过了什么 MobileServiceClient ? 我的理解是,如果 .CurrentUser 然后,它将在标题中包含它作为 X-ZUMO-AUTH 标题。

    服务器登录: 

    [Route(".auth/login/custom")]
public class AuthController : ApiController
{
    private readonly AppContext _context;

    private readonly string
        _singningKey = Environment.GetEnvironmentVariable("WEBSITE_AUTH_SIGNING_KEY");

    private readonly string
        _audience;

    private readonly string
        _issuer;

    public AuthController()
    {
        _context = new AppContext();

        var website = Environment.GetEnvironmentVariable("WEBSITE_HOSTNAME");
        _audience = $"https://{website}/";
        _issuer = $"https://{website}/";
    }

    public HttpResponseMessage Post([FromBody] LoginUser body)
    {
        if (body?.Username == null || body.Password == null || body.Username.Length == 0 || body.Password.Length == 0)
        {
            return Request.CreateUnauthorizedResponse();
        }

        if (!IsValidUser(body))
        {
            return Request.CreateUnauthorizedResponse();
        }

        var claims = new[] { new Claim(JwtRegisteredClaimNames.Sub, body.Username) };

        var token = AppServiceLoginHandler.CreateToken(claims,
                _singningKey,
                _audience,
                _issuer,
                TimeSpan.FromHours(24));

        return Request.CreateResponse(HttpStatusCode.OK, new LoginResult
        {
            AuthenticationToken = token.RawData,
            User = new LoginResultUser() { UserId = body.Username }
        });
    }

    protected override void Dispose(bool disposing)
    {
        if (disposing)
        {
            _context.Dispose();
        }
        base.Dispose(disposing);
    }

    private bool IsValidUser(LoginUser user)
    {
        .. this works fine
    }
}

public class LoginUser
{
    [JsonProperty("username")]
    public string Username { get; set; }
    [JsonProperty("password")]
    public string Password { get; set; }
}

public class LoginResultUser
{
    [JsonProperty("userId")]
    public string UserId { get; set; }
}

public class LoginResult
{
    [JsonProperty("authenticationToken")]
    public string AuthenticationToken { get; set; }
    [JsonProperty("user")]
    public LoginResultUser User { get; set; }
}

    客户端登录: 

    var database = new MobileServiceClient(BackendApiServerAddress);
var result = await database.LoginAsync("custom", JObject.FromObject(user)); //this sets database.CurrentUser to a MobileServiceUser with MobileAuthenticationToken and UserId and returns the value
await database.SyncContext.PushAsync(); // this fails

    例外情况:

    根据您的描述,您的自定义身份验证可以验证客户端用户并生成 authenticationToken 成功地我建议您检查身份验证/授权设置,并确保设置 请求未通过身份验证时要采取的操作 到 允许请求(无操作) 在Azure移动应用程序的“设置验证/授权”下。此外,我建议您利用 fiddler 调用时捕获网络跟踪 await database.SyncContext.PushAsync() . 此外,还可以使用postman对表控制器模拟请求,如下所示,以缩小此问题: 

    GET https://{your-app-name}.azurewebsites.net/tables/{table-name}
Header x-zumo-auth:{authenticationToken}

    此外,你还可以阅读阿德里安·霍尔的书 Custom Authentication 和 Authentication in the Backend .
