Semantic Kernel/C#：接入智谱AI的两种方式

news 2025/11/27 13:25:01

Semantie Kernel中对话请求默认是发送到OpenAI去的：

其他与OpenAI对话请求接口兼任的模型平台，一般只需要修改host即可，如下所示：

 default:uriBuilder = new UriBuilder(request.RequestUri){// 这里是你要修改的 URLScheme = "https",Host = host,Path = "v1/chat/completions",};request.RequestUri = uriBuilder.Uri;break;

但是智谱AI的对话接口地址如下：

在python中这样就可以用，但SemanticKernel中好像还没有base_url的设置。

有两种方式可以实现。

一种是想和之前其他模型用相同的方式，把智普平台作为一种特殊的方式处理。

在appsettings.json中添加一个Platform字段，请求接口完全兼容OpenAI的可以不写：

创建Kernel是这样的：

 var builder = Kernel.CreateBuilder().AddOpenAIChatCompletion(modelId: OpenAIOption.ChatModel,apiKey: OpenAIOption.Key,httpClient: new HttpClient(handler));
_kernel = builder.Build();

然后在OpenAIHttpClientHandler为智谱平台做一下不同的处理：

public class OpenAIHttpClientHandler : HttpClientHandler
{protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken){UriBuilder uriBuilder;string url = OpenAIOption.Endpoint;string platform = OpenAIOption.Platform;Uri uri = new Uri(url);string host = uri.Host;switch (request.RequestUri?.LocalPath){case "/v1/chat/completions":switch(platform){case "ZhiPu":uriBuilder = new UriBuilder(request.RequestUri){// 这里是你要修改的 URLScheme = "https",Host = host,Path = "api/paas/v4/chat/completions",};request.RequestUri = uriBuilder.Uri;break;default:uriBuilder = new UriBuilder(request.RequestUri){// 这里是你要修改的 URLScheme = "https",Host = host,Path = "v1/chat/completions",};request.RequestUri = uriBuilder.Uri;break;}break;}HttpResponseMessage response = await base.SendAsync(request, cancellationToken);return response;}
}
