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:
csharp
default:
uriBuilder = new UriBuilder(request.RequestUri)
{
// 这里是你要修改的 URL
Scheme = "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:
csharp
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:
csharp
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 URL
Scheme = "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 URL
Scheme = "https",
Host = host,
Path = "v1/chat/completions",
};
request.RequestUri = uriBuilder.Uri;
break;
}
break;
}
HttpResponseMessage response = await base.SendAsync(request, cancellationToken);
return response;
}
}
尝试是否成功:
另一种方式更加简单,只需要在appsettings.json中这样写:
使用这种方式创建Kernel即可:
尝试是否成功:
在AvaloniaChat中为了和其他平台保持统一的使用方式,我选择第一种方式。
