Semantie Kernel中对话请求默认是发送到OpenAI去的

其他与OpenAI对话请求接口兼容的模型平台，一般只需要修改host即可，path不需要修改，可以通过HttpClientHandler修改

接入智普AI

但是智谱AI的对话接口地址是api/paas/v4/chat/completions,和OpenAI不同，所以需要修改host和path

安装Nuget：

<PackageReference Include="Microsoft.SemanticKernel" Version="1.25.0" />

代码：

var builder = Kernel.CreateBuilder();
var httpClient = new HttpClient(new OpenAIHttpClientHandler());

builder = builder.AddOpenAIChatCompletion(modelId: "glm-4",
    apiKey: "xxxxxxx", httpClient: httpClient);

var kernel = builder.Build();
var chatCompletionService = kernel.GetRequiredService<IChatCompletionService>();

var history = new ChatHistory();
string? userInput;
do
{
    // Collect user input
    Console.Write("User > ");
    userInput = Console.ReadLine();

    // Add user input
    history.AddUserMessage(userInput);

    // Get the response from the AI
    var result = await chatCompletionService.GetChatMessageContentAsync(history, kernel: kernel);

    // Print the results
    Console.WriteLine("Assistant > " + result);

    // Add the message from the agent to the chat history
    history.AddMessage(result.Role, result.Content ?? string.Empty);
} while (userInput is not null);

使用HttpClientHandler修改host和path

public class OpenAIHttpClientHandler : HttpClientHandler
{
    protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
    {
        switch (request.RequestUri?.LocalPath)
        {
            case "/v1/chat/completions":
                var uriBuilder = new UriBuilder(request.RequestUri)
                {
                    Scheme = "https",
                    Host = "open.bigmodel.cn",
                    Path = "api/paas/v4/chat/completions",//其他与OpenAI对话请求接口兼容的模型平台，一般只需要修改host即可，不需要修改path
                };
                request.RequestUri = uriBuilder.Uri;
                break;
        }

        HttpResponseMessage response = await base.SendAsync(request, cancellationToken);

        return response;
    }
}
