我将尝试创建Jwt令牌授权。为此，我有一个包含以下代码的发行者部分:
public override Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
{
context.OwinContext.Response.Headers.Add("Access-Control-Allow-Origin", new[] {"*"});
Users user;
using (var db = new UserStore())
{
user = Task.Run(()=> db.FindUser(context.UserName, context.Password, context.ClientId)).Result;
}
if (user == null)
{
context.SetError("invalid_grant", "The user name or password is incorrect");
return Task.FromResult<object>(null);
}
var identity = new ClaimsIdentity("JWT");
identity.AddClaim(new Claim(ClaimTypes.Name, user.Email));
identity.AddClaim(new Claim("sub", context.UserName));
identity.AddClaim(new Claim(ClaimTypes.Role, user.Roles.Name));
var props = new AuthenticationProperties(new Dictionary<string, string>
{
{
"audience", context.ClientId ?? string.Empty
}
});
var ticket = new AuthenticationTicket(identity, props);
context.Validated(ticket);
return Task.FromResult<object>(null);
}
还有一个“资源”部分，应该接受令牌：
public void ConfigureOAuth(IAppBuilder app)
{
var issuer = SiteGlobal.Issuer;
var audience = SiteGlobal.Audience;
var secret = TextEncodings.Base64Url.Decode(SiteGlobal.Secret);
app.UseJwtBearerAuthentication(
new JwtBearerAuthenticationOptions
{
AuthenticationMode = AuthenticationMode.Active,
AllowedAudiences = new[] { audience },
IssuerSecurityTokenProviders = new IIssuerSecurityTokenProvider[]
{
new SymmetricKeyIssuerSecurityTokenProvider(issuer, secret)
}
});
}
据我所见，发行的令牌是有效的（我在jwt.io上进行了验证），因此问题出在别处。当我在Postman中发送带有
[Authorize]属性保护的控制器调用时，它总是返回401代码。请问如何解决这个问题？附注：这是我实现自定义Jwt格式的方式：
public string Protect(AuthenticationTicket data)
{
if (data == null)
{
throw new ArgumentNullException("data");
}
string audienceId = data.Properties.Dictionary.ContainsKey(AudiencePropertyKey) ? data.Properties.Dictionary[AudiencePropertyKey] : null;
if (string.IsNullOrWhiteSpace(audienceId)) throw new InvalidOperationException("AuthenticationTicket.Properties does not include audience");
Audience audience;
using (var store = new AudienceStore())
{
audience = Task.Run(()=> store.FindAudience(audienceId)).Result;
}
var symmetricKeyAsBase64 = audience.Base64Secret;
var signingKey = new InMemorySymmetricSecurityKey(Encoding.UTF8.GetBytes(symmetricKeyAsBase64));
var signingCredentials = new SigningCredentials(signingKey, SecurityAlgorithms.HmacSha256Signature, SecurityAlgorithms.Sha256Digest);
var issued = data.Properties.IssuedUtc;
var expires = data.Properties.ExpiresUtc;
var token = new JwtSecurityToken(_issuer, audienceId, data.Identity.Claims, issued.Value.UtcDateTime, expires.Value.UtcDateTime, signingCredentials);
var handler = new JwtSecurityTokenHandler();
var jwt = handler.WriteToken(token);
return jwt;
}
PS：很抱歉，但我忘记解释了“issuer”代码的部分，它是独立的应用程序，而“audience”是受保护的Web API。这是两个不同的应用程序独立运行。
jwt没有经验，只有通过URL进行REST查询的经验，其中需要请求头Authorization: Basic <加密的用户名：密码>，如果出现任何错误（密码/名称/语法），它会向我抛出401。 - TatranskymedvedAuthorization: Bearer <jwt>格式。 - cchamberlain
