This document outlines the authentication model for the OpenAPI plugin. + +## The `AuthenticateRequestAsyncCallback` delegate + +`AuthenticateRequestAsyncCallback` is a delegate type that serves as a callback function for adding authentication information to HTTP requests sent by the OpenAPI plugin. + +```csharp +public delegate Task AuthenticateRequestAsyncCallback(HttpRequestMessage request); +``` + +Developers may optionally provide an implementation of this delegate when importing an OpenAPI plugin to the Kernel. +The delegate is then passed through to the `RestApiOperationRunner`, which is responsible for building the HTTP payload and sending the request for each REST API operation. +Before the API request is sent, the delegate is executed with the HTTP request message as the parameter, allowing the request message to be updated with any necessary authentication information. + +This pattern was designed to be flexible enough to support a wide variety of authentication frameworks. + +## Authentication Providers example + +### BasicAuthenticationProvider + +This class implements the HTTP "basic" authentication scheme. The constructor accepts a `Func` which defines how to retrieve the user's credentials. +When the `AuthenticateRequestAsync` method is called, it retrieves the credentials, encodes them as a UTF-8 encoded Base64 string, and adds them to the `HttpRequestMessage`'s authorization header. + +The following code demonstrates how to use this provider: + +```csharp +var basicAuthProvider = new BasicAuthenticationProvider(() => +{ + // JIRA API expects credentials in the format "email:apikey" + return Task.FromResult( + Env.Var("MY_EMAIL_ADDRESS") + ":" + Env.Var("JIRA_API_KEY") + ); +}); +var plugin = kernel.ImportOpenApiPluginFromResource(PluginResourceNames.Jira, new OpenApiFunctionExecutionParameters { AuthCallback = basicAuthProvider.AuthenticateRequestAsync } ); +``` + +### BearerAuthenticationProvider + +This class implements the HTTP "bearer" authentication scheme. The constructor accepts a `Func` which defines how to retrieve the bearer token. +When the `AuthenticateRequestAsync` method is called, it retrieves the token and adds it to the `HttpRequestMessage`'s authorization header. + +The following code demonstrates how to use this provider: + +```csharp +var bearerAuthProvider = new BearerAuthenticationProvider(() => +{ + return Task.FromResult(Env.Var("AZURE_KEYVAULT_TOKEN")); +}); +var plugin = kernel.ImportOpenApiPluginFromResource(PluginResourceNames.AzureKeyVault, new OpenApiFunctionExecutionParameters { AuthCallback = bearerAuthProvider.AuthenticateRequestAsync } ) +``` + +### InteractiveMsalAuthenticationProvider + +This class uses the [Microsoft Authentication Library (MSAL)](https://learn.microsoft.com/en-us/azure/active-directory/develop/msal-overview)'s .NET library to authenticate the user and acquire an OAuth token. +It follows the interactive [authorization code flow](https://learn.microsoft.com/en-us/azure/active-directory/develop/v2-oauth2-auth-code-flow), requiring the user to sign in with a Microsoft or Azure identity. +This is particularly useful for authenticating requests to the Microsoft Graph or Azure APIs. + +Once the token is acquired, it is added to the HTTP authentication header via the `AuthenticateRequestAsync` method, which is inherited from `BearerAuthenticationProvider`. + +To construct this provider, the caller must specify: + +- _Client ID_ - identifier of the calling application. This is acquired by [registering your application with the Microsoft Identity platform](https://learn.microsoft.com/en-us/azure/active-directory/develop/quickstart-register-app). +- _Tenant ID_ - identifier of the target service tenant, or "common" +- _Scopes_ - permissions being requested +- _Redirect URI_ - for redirecting the user back to the application. (When running locally, this is typically http://localhost.) + +```csharp +var msalAuthProvider = new InteractiveMsalAuthenticationProvider( + Env.Var("AZURE_KEYVAULT_CLIENTID"), // clientId + Env.Var("AZURE_KEYVAULT_TENANTID"), // tenantId + new string[] { ".default" }, // scopes + new Uri("http://localhost") // redirectUri +); +var plugin = kernel.ImportOpenApiPluginFromResource(PluginResourceNames.AzureKeyVault, new OpenApiFunctionExecutionParameters { AuthCallback = msalAuthProvider.AuthenticateRequestAsync } ) +``` diff --git a/dotnet/samples/AgentSyntaxExamples/RepoUtils/ObjectExtensions.cs b/dotnet/samples/AgentSyntaxExamples/RepoUtils/ObjectExtensions.cs new file mode 100644 index 000000000000..144074f96116 --- /dev/null +++ b/dotnet/samples/AgentSyntaxExamples/RepoUtils/ObjectExtensions.cs @@ -0,0 +1,15 @@ +// Copyright (c) Microsoft.

This document outlines the authentication model for the OpenAPI plugin. - -## The `AuthenticateRequestAsyncCallback` delegate - -`AuthenticateRequestAsyncCallback` is a delegate type that serves as a callback function for adding authentication information to HTTP requests sent by the OpenAPI plugin. - -```csharp -public delegate Task AuthenticateRequestAsyncCallback(HttpRequestMessage request); ``` -Developers may optionally provide an implementation of this delegate when importing an OpenAPI plugin to the Kernel. -The delegate is then passed through to the `RestApiOperationRunner`, which is responsible for building the HTTP payload and sending the request for each REST API operation. -Before the API request is sent, the delegate is executed with the HTTP request message as the parameter, allowing the request message to be updated with any necessary authentication information. - -This pattern was designed to be flexible enough to support a wide variety of authentication frameworks. - -## Authentication Providers example - -### BasicAuthenticationProvider - -This class implements the HTTP "basic" authentication scheme. The constructor accepts a `Func` which defines how to retrieve the user's credentials. -When the `AuthenticateRequestAsync` method is called, it retrieves the credentials, encodes them as a UTF-8 encoded Base64 string, and adds them to the `HttpRequestMessage`'s authorization header. - -The following code demonstrates how to use this provider: - -```csharp -var basicAuthProvider = new BasicAuthenticationProvider(() => -{ - // JIRA API expects credentials in the format "email:apikey" - return Task.FromResult( - Env.Var("MY_EMAIL_ADDRESS") + ":" + Env.Var("JIRA_API_KEY") - ); -}); -var plugin = kernel.ImportOpenApiPluginFromResource(PluginResourceNames.Jira, new OpenApiFunctionExecutionParameters { AuthCallback = basicAuthProvider.AuthenticateRequestAsync } ); -``` - -### BearerAuthenticationProvider - -This class implements the HTTP "bearer" authentication scheme. The constructor accepts a `Func` which defines how to retrieve the bearer token. -When the `AuthenticateRequestAsync` method is called, it retrieves the token and adds it to the `HttpRequestMessage`'s authorization header. - -The following code demonstrates how to use this provider: - -```csharp -var bearerAuthProvider = new BearerAuthenticationProvider(() => -{ - return Task.FromResult(Env.Var("AZURE_KEYVAULT_TOKEN")); -}); -var plugin = kernel.ImportOpenApiPluginFromResource(PluginResourceNames.AzureKeyVault, new OpenApiFunctionExecutionParameters { AuthCallback = bearerAuthProvider.AuthenticateRequestAsync } ) -``` - -### InteractiveMsalAuthenticationProvider - -This class uses the [Microsoft Authentication Library (MSAL)](https://learn.microsoft.com/en-us/azure/active-directory/develop/msal-overview)'s .NET library to authenticate the user and acquire an OAuth token. -It follows the interactive [authorization code flow](https://learn.microsoft.com/en-us/azure/active-directory/develop/v2-oauth2-auth-code-flow), requiring the user to sign in with a Microsoft or Azure identity. -This is particularly useful for authenticating requests to the Microsoft Graph or Azure APIs. - -Once the token is acquired, it is added to the HTTP authentication header via the `AuthenticateRequestAsync` method, which is inherited from `BearerAuthenticationProvider`. - -To construct this provider, the caller must specify: - -- _Client ID_ - identifier of the calling application. This is acquired by [registering your application with the Microsoft Identity platform](https://learn.microsoft.com/en-us/azure/active-directory/develop/quickstart-register-app). -- _Tenant ID_ - identifier of the target service tenant, or "common" -- _Scopes_ - permissions being requested -- _Redirect URI_ - for redirecting the user back to the application. (When running locally, this is typically http://localhost.) - -```csharp -var msalAuthProvider = new InteractiveMsalAuthenticationProvider( - Env.Var("AZURE_KEYVAULT_CLIENTID"), // clientId - Env.Var("AZURE_KEYVAULT_TENANTID"), // tenantId - new string[] { ".default" }, // scopes - new Uri("http://localhost") // redirectUri -); -var plugin = kernel.ImportOpenApiPluginFromResource(PluginResourceNames.AzureKeyVault, new OpenApiFunctionExecutionParameters { AuthCallback = msalAuthProvider.AuthenticateRequestAsync } ) -``` From d58e416e535a420561368050d4bf42b50f1c70ba Mon Sep 17 00:00:00 2001 From: Chris Rickman Date: Sat, 30 Mar 2024 21:38:39 -0700 Subject: [PATCH 004/174] Build --- dotnet/src/Agents/Framework/AgentChannel.cs | 4 ++-- dotnet/src/Agents/Framework/AgentNexus.cs | 2 +- dotnet/src/Agents/Framework/Internal/BroadcastQueue.cs | 8 ++++---- dotnet/src/Agents/Framework/LocalChannel.cs | 4 ++-- 4 files changed, 9 insertions(+), 9 deletions(-) diff --git a/dotnet/src/Agents/Framework/AgentChannel.cs b/dotnet/src/Agents/Framework/AgentChannel.cs index 066e192d9e26..beb0f32bda1f 100644 --- a/dotnet/src/Agents/Framework/AgentChannel.cs +++ b/dotnet/src/Agents/Framework/AgentChannel.cs @@ -12,11 +12,11 @@ namespace Microsoft.SemanticKernel.Agents; public abstract class AgentChannel { /// - /// Recieve the converation messages.
