// 记录请求信息 Console.WriteLine($Sending request to: {ctx.Url}); // 调用基类方法继续处理 return await base.SendRequestAsync(request, ctx); } } // 使用自定义处理器 var client new CopilotClient(); var session await client.CreateSessionAsync( new SessionConfig { RequestHandler new CustomRequestHandler() } );Python示例代码class CustomRequestHandler(CopilotRequestHandler): async def send_request(self, request: httpx.Request, ctx: CopilotRequestContext) - httpx.Response: # 修改请求URL if api.openai.com in str(request.url): request.url request.url.copy_with(hostmy-proxy.com) # 添加认证头 request.headers[Authorization] fBearer {MY_API_KEY} # 调用父类方法 return await super().send_request(request, ctx) # 使用自定义处理器 client CopilotClient() session await client.create_session( request_handlerCustomRequestHandler() )️ 高级用例和最佳实践1. 实现请求代理通过请求处理器你可以将AI请求路由到不同的后端服务public class LoadBalancingRequestHandler : CopilotRequestHandler { private readonly Liststring _endpoints new() { https://ai-service-1.example.com, https://ai-service-2.example.com }; protected override async TaskHttpResponseMessage SendRequestAsync( HttpRequestMessage request, CopilotRequestContext ctx) { // 负载均衡逻辑 var selectedEndpoint _endpoints[DateTime.Now.Second % _endpoints.Count]; var newUrl new Uri(selectedEndpoint request.RequestUri.PathAndQuery); request.RequestUri newUrl; return await base.SendRequestAsync(request, ctx); } }2. 添加请求监控和日志class MonitoringRequestHandler(CopilotRequestHandler): def __init__(self): self.metrics {} async def send_request(self, request: httpx.Request, ctx: CopilotRequestContext) - httpx.Response: start_time time.time() try: response await super().send_request(request, ctx) duration time.time() - start_time # 记录性能指标 self._record_metrics(ctx.url, duration, response.status_code) return response except Exception as e: self._record_error(ctx.url, str(e)) raise def _record_metrics(self, url, duration, status_code): # 实现指标记录逻辑 pass3. 实现请求重试机制public class RetryRequestHandler : CopilotRequestHandler { private readonly int _maxRetries 3; protected override async TaskHttpResponseMessage SendRequestAsync( HttpRequestMessage request, CopilotRequestContext ctx) { for (int i 0; i _maxRetries; i) { try { return await base.SendRequestAsync(request, ctx); } catch (HttpRequestException ex) when (i _maxRetries - 1) { // 等待后重试 await Task.Delay(100 * (int)Math.Pow(2, i)); continue; } } throw new InvalidOperationException(Max retries exceeded); } } 请求处理器的性能优化技巧连接池管理对于高并发场景合理管理HTTP连接池至关重要class OptimizedRequestHandler(CopilotRequestHandler): def __init__(self): # 创建自定义HTTP客户端优化连接池 limits httpx.Limits( max_connections100, max_keepalive_connections20, keepalive_expiry30.0 ) self._client httpx.AsyncClient( limitslimits, timeouthttpx.Timeout(30.0) ) async def send_request(self, request: httpx.Request, ctx: CopilotRequestContext) - httpx.Response: # 使用优化的客户端 return await self._client.send(request, streamTrue) async def __aexit__(self, exc_type, exc_val, exc_tb): await self._client.aclose()响应流式处理对于大模型响应使用流式处理避免内存溢出private static async Task StreamResponseAsync( HttpResponseMessage response, LlmInferenceExchange exchange) { await exchange.StartResponseAsync( (int)response.StatusCode, response.ReasonPhrase, HeadersToMultiMap(response)).ConfigureAwait(false); var ct exchange.Context.CancellationToken; using var stream await response.Content.ReadAsStreamAsync(ct).ConfigureAwait(false); var buffer new byte[16 * 1024]; int read; while ((read await stream.ReadAsync(buffer.AsMemory(), ct).ConfigureAwait(false)) 0) { await exchange.WriteResponseAsync( new ReadOnlyMemorybyte(buffer, 0, read) ).ConfigureAwait(false); } await exchange.EndResponseAsync().ConfigureAwait(false); } 安全性和认证处理自定义认证方案请求处理器让你能够实现复杂的认证逻辑class SecureRequestHandler(CopilotRequestHandler): def __init__(self, auth_provider): self.auth_provider auth_provider async def send_request(self, request: httpx.Request, ctx: CopilotRequestContext) - httpx.Response: # 获取动态令牌 token await self.auth_provider.get_token() # 添加认证头 request.headers[Authorization] fBearer {token} # 添加额外的安全头 request.headers[X-Request-ID] ctx.request_id request.headers[X-Session-ID] ctx.session_id or return await super().send_request(request, ctx)请求验证和过滤public class ValidationRequestHandler : CopilotRequestHandler { protected override async TaskHttpResponseMessage SendRequestAsync( HttpRequestMessage request, CopilotRequestContext ctx) { // 验证请求URL if (!IsAllowedUrl(ctx.Url)) { throw new UnauthorizedAccessException($URL not allowed: {ctx.Url}); } // 检查请求头 if (ContainsSensitiveData(ctx.Headers)) { // 清理敏感信息 request.Headers.Remove(Authorization); } return await base.SendRequestAsync(request, ctx); } private bool IsAllowedUrl(string url) { // 实现URL白名单逻辑 return url.StartsWith(https://api.openai.com/) || url.StartsWith(https://api.anthropic.com/); } } 错误处理和故障恢复优雅的错误处理class ResilientRequestHandler(CopilotRequestHandler): async def send_request(self, request: httpx.Request, ctx: CopilotRequestContext) - httpx.Response: try: return await super().send_request(request, ctx) except httpx.TimeoutException: # 超时处理 return self._create_timeout_response() except httpx.HTTPStatusError as e: # HTTP错误处理 if e.response.status_code 429: # 速率限制 - 实现退避策略 await asyncio.sleep(1) return await super().send_request(request, ctx) raise def _create_timeout_response(self): # 创建自定义超时响应 return httpx.Response( 504, headers{Content-Type: application/json}, contentb{error: Request timeout} ) 监控和可观测性集成集成OpenTelemetrypublic class TelemetryRequestHandler : CopilotRequestHandler { private readonly Tracer _tracer; public TelemetryRequestHandler(Tracer tracer) { _tracer tracer; } protected override async TaskHttpResponseMessage SendRequestAsync( HttpRequestMessage request, CopilotRequestContext ctx) { using var span _tracer.StartActiveSpan(copilot.request); span.SetAttribute(request.id, ctx.RequestId); span.SetAttribute(request.url, ctx.Url); span.SetAttribute(session.id, ctx.SessionId); try { var response await base.SendRequestAsync(request, ctx); span.SetAttribute(response.status, (int)response.StatusCode); return response; } catch (Exception ex) { span.RecordException(ex); span.SetStatus(Status.Error); throw; } } } 总结GitHub Copilot SDK请求处理器是一个强大的工具它为开发者提供了对AI请求的完全控制能力。通过合理使用请求处理器你可以实现自定义路由逻辑️ - 将请求导向不同的AI服务提供商增强安全性 - 添加认证、验证和过滤逻辑优化性能⚡ - 实现连接池、缓存和重试机制集成监控 - 添加指标收集和分布式追踪处理错误 - 实现优雅的故障恢复策略无论你是构建企业级AI应用还是需要特殊定制的AI集成场景GitHub Copilot SDK的请求处理器都能为你提供必要的灵活性和控制力。通过深入理解和使用这个核心组件你可以构建出更加可靠、高效和安全的AI驱动应用。记住请求处理器是GitHub Copilot SDK架构中的关键组件它连接了你的应用程序和强大的AI能力让你能够以编程方式控制整个AI请求生命周期。开始探索这个强大的功能为你的应用添加智能化的AI能力吧✨【免费下载链接】copilot-sdkMulti-platform SDK for integrating GitHub Copilot Agent into apps and services项目地址: https://gitcode.com/GitHub_Trending/co/copilot-sdk创作声明：本文部分内容由AI辅助生成（AIGC），仅供参考
