从自定义 header 中检索访问令牌

Retrieve access token from a customised header

在我的 Web API 中,我想从请求中的 Cookies header 中获取访问令牌,然后对令牌进行验证。目前,IdentityServer3.AccessTokenValidation 包用于验证 Bearer 令牌,它仅从授权 header 中查找令牌。最好我想继续使用相同的不记名令牌验证过程,但是从 Cookies header 获取令牌,用方便的代码听起来可行吗?谢谢

只需实现您自己的 TokenProvider 并将其提供给 AccessTokenValidationMiddleware:

public class MyCustomTokenProvider : IOAuthBearerAuthenticationProvider
{
    public Task RequestToken(OAuthRequestTokenContext context)
    {
        if (context.Token == null)
        {
            //try get from cookie
            var tokenCookie = context.Request.Cookies["myCookieName"];

            if (tokenCookie != null)
            {
                context.Token = tokenCookie;
            }
        }

        return Task.FromResult(0);
    }

    public Task ValidateIdentity(OAuthValidateIdentityContext context)
    {
        throw new NotImplementedException();
    }

    public Task ApplyChallenge(OAuthChallengeContext context)
    {
        throw new NotImplementedException();
    }
}

在你的Startup.cs中:

app.UseIdentityServerBearerTokenAuthentication(new IdentityServerBearerTokenAuthenticationOptions
{
    Authority = "http://myhost",
    RequiredScopes = new[] { "my-scope" },
    TokenProvider = new MyCustomTokenProvider()
});
