* failing test * failing test but needs real butterfly server running..need to fix that...also worked out ive broken tracing...yey * brought in butterfly source code so i can work out how to write acceptance tests for this... * fixed the bug but still need to fix tracing * tracing working again across services but need to make tracing hook into new Ocelot middleware as it still uses asp.net middleware * removed butterfly libs brought in for testing

Authentication
|
|
==============
|
|
|
|
In order to authenticate ReRoutes and subsequently use any of Ocelot's claims based features such as authorisation or modifying the request with values from the token. Users must register authentication services in their Startup.cs as usual but they provide a scheme (authentication provider key) with each registration e.g.
|
|
|
|
.. code-block:: csharp
|
|
|
|
public void ConfigureServices(IServiceCollection services)
|
|
{
|
|
var authenticationProviderKey = "TestKey";
|
|
|
|
services.AddAuthentication()
|
|
.AddJwtBearer(authenticationProviderKey, x =>
|
|
{
|
|
});
|
|
}
|
|
|
|
|
|
In this example TestKey is the scheme that this provider has been registered with.
|
|
We then map this to a ReRoute in the configuration e.g.
|
|
|
|
.. code-block:: json
|
|
|
|
"ReRoutes": [{
|
|
"DownstreamHostAndPorts": [
|
|
{
|
|
"Host": "localhost",
|
|
"Port": 51876,
|
|
}
|
|
],
|
|
"DownstreamPathTemplate": "/",
|
|
"UpstreamPathTemplate": "/",
|
|
"UpstreamHttpMethod": ["Post"],
|
|
"ReRouteIsCaseSensitive": false,
|
|
"DownstreamScheme": "http",
|
|
"AuthenticationOptions": {
|
|
"AuthenticationProviderKey": "TestKey",
|
|
"AllowedScopes": []
|
|
}
|
|
}]
|
|
|
|
When Ocelot runs it will look at this ReRoutes AuthenticationOptions.AuthenticationProviderKey
|
|
and check that there is an Authentication provider registered with the given key. If there isn't then Ocelot
|
|
will not start up, if there is then the ReRoute will use that provider when it executes.
|
|
|
|
If a ReRoute is authenticated Ocelot will invoke whatever scheme is associated with it while executing the authentication middleware. If the request fails authentication Ocelot returns a http status code 401.
|
|
|
|
JWT Tokens
|
|
^^^^^^^^^^
|
|
|
|
If you want to authenticate using JWT tokens maybe from a provider like Auth0 you can register your authentication middleware as normal e.g.
|
|
|
|
.. code-block:: csharp
|
|
|
|
public void ConfigureServices(IServiceCollection services)
|
|
{
|
|
var authenticationProviderKey = "TestKey";
|
|
|
|
services.AddAuthentication()
|
|
.AddJwtBearer(authenticationProviderKey, x =>
|
|
{
|
|
x.Authority = "test";
|
|
x.Audience = "test";
|
|
});
|
|
|
|
services.AddOcelot();
|
|
}
|
|
|
|
Then map the authentication provider key to a ReRoute in your configuration e.g.
|
|
|
|
.. code-block:: json
|
|
|
|
"ReRoutes": [{
|
|
"DownstreamHostAndPorts": [
|
|
{
|
|
"Host": "localhost",
|
|
"Port": 51876,
|
|
}
|
|
],
|
|
"DownstreamPathTemplate": "/",
|
|
"UpstreamPathTemplate": "/",
|
|
"UpstreamHttpMethod": ["Post"],
|
|
"ReRouteIsCaseSensitive": false,
|
|
"DownstreamScheme": "http",
|
|
"AuthenticationOptions": {
|
|
"AuthenticationProviderKey": "TestKey",
|
|
"AllowedScopes": []
|
|
}
|
|
}]
|
|
|
|
|
|
|
|
Identity Server Bearer Tokens
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
In order to use IdentityServer bearer tokens register your IdentityServer services as usual in ConfigureServices with a scheme (key). If you don't understand how to do this please consul the IdentityServer documentation.
|
|
|
|
.. code-block:: csharp
|
|
|
|
public void ConfigureServices(IServiceCollection services)
|
|
{
|
|
var authenticationProviderKey = "TestKey";
|
|
var options = o =>
|
|
{
|
|
o.Authority = "https://whereyouridentityserverlives.com";
|
|
o.ApiName = "api";
|
|
o.SupportedTokens = SupportedTokens.Both;
|
|
o.ApiSecret = "secret";
|
|
};
|
|
|
|
services.AddAuthentication()
|
|
.AddIdentityServerAuthentication(authenticationProviderKey, options);
|
|
|
|
services.AddOcelot();
|
|
}
|
|
|
|
Then map the authentication provider key to a ReRoute in your configuration e.g.
|
|
|
|
.. code-block:: json
|
|
|
|
"ReRoutes": [{
|
|
"DownstreamHostAndPorts": [
|
|
{
|
|
"Host": "localhost",
|
|
"Port": 51876,
|
|
}
|
|
],
|
|
"DownstreamPathTemplate": "/",
|
|
"UpstreamPathTemplate": "/",
|
|
"UpstreamHttpMethod": ["Post"],
|
|
"ReRouteIsCaseSensitive": false,
|
|
"DownstreamScheme": "http",
|
|
"AuthenticationOptions": {
|
|
"AuthenticationProviderKey": "TestKey",
|
|
"AllowedScopes": []
|
|
}
|
|
}]
|
|
|
|
Allowed Scopes
|
|
^^^^^^^^^^^^^
|
|
|
|
If you add scopes to AllowedScopes Ocelot will get all the user claims (from the token) of the type scope and make sure that the user has all of the scopes in the list.
|
|
|
|
This is a way to restrict access to a ReRoute on a per scope basis. |
