如何使用插件

Runtime AI Chatbot Integrator 提供两大主要功能：文本到文本聊天（Text-to-Text chat）和文本到语音转换（Text-to-Speech，TTS）。两项功能遵循相似的工作流程：

注册您的API提供商令牌
配置功能特定设置
发送请求并处理响应

注册提供商令牌

在发送任何请求之前，请使用 RegisterProviderToken 函数注册您的API提供商令牌。

Blueprint
C++

在Blueprint中注册提供商令牌

// Register an OpenAI provider token, as an example
UAIChatbotCredentialsManager::RegisterProviderToken(
    EAIChatbotIntegratorOrgs::OpenAI, 
    TEXT("sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx")
);

文本转文本聊天功能

该插件为每个服务提供商支持两种聊天请求模式：

非流式聊天请求

通过单次调用获取完整响应。

文本转语音 (TTS) 功能

使用领先的 TTS 提供商将文本转换为高质量的语音音频。该插件返回原始音频数据 (TArray<uint8>)，您可以根据项目需求进行处理。

以下示例演示了如何使用 Runtime Audio Importer 插件（参见音频导入文档）进行音频播放处理，但 Runtime AI Chatbot Integrator 设计灵活。插件仅返回原始音频数据，您可以完全自由地根据具体用例进行处理，包括音频播放、保存到文件、进一步音频处理、传输到其他系统、自定义可视化等。

非流式 TTS 请求

非流式 TTS 请求会在整个文本处理完成后一次性返回完整的音频数据。这种方法适用于较短的文本，等待完整音频不会造成问题。

错误处理

发送任何请求时，必须通过回调函数中的 ErrorStatus 检查来处理潜在错误。ErrorStatus 会提供请求过程中可能出现的任何问题信息。

Blueprint
C++

错误处理

// Example of error handling in a request
UAIChatbotIntegratorOpenAI::SendChatRequestNative(
    Settings, 
    FOnOpenAIChatCompletionResponseNative::CreateWeakLambda(
        this, 
        [this](const FString& Response, const FChatbotIntegratorErrorStatus& ErrorStatus)
        {
            if (ErrorStatus.bIsError)
            {
                // Handle the error
                UE_LOG(LogTemp, Error, TEXT("Chat request failed: %s"), *ErrorStatus.ErrorMessage);
            }
            else 
            {
                // Process the successful response
                UE_LOG(LogTemp, Log, TEXT("Received response: %s"), *Response);
            }
        }
    )
);

取消请求

该插件允许您在文本转文本和TTS请求进行中时取消它们。当您需要中断长时间运行的请求或动态改变对话流程时，这个功能会非常有用。

Blueprint
C++

取消请求

// Example of cancelling requests
UAIChatbotIntegratorOpenAI* ChatRequest = UAIChatbotIntegratorOpenAI::SendChatRequestNative(
    ChatSettings, 
    ChatResponseCallback
);

// Cancel the chat request at any time
ChatRequest->Cancel();

// TTS requests can be cancelled similarly
UAIChatbotIntegratorOpenAITTS* TTSRequest = UAIChatbotIntegratorOpenAITTS::SendTTSRequestNative(
    TTSSettings, 
    TTSResponseCallback
);

// Cancel the TTS request
TTSRequest->Cancel();

最佳实践

始终通过检查回调中的 ErrorStatus 来处理潜在错误
注意API速率限制和成本控制
对于长文本或交互式对话使用流式传输模式
考虑取消不再需要的请求以高效管理资源
对较长文本使用流式TTS以降低感知延迟
音频处理方面，Runtime Audio Importer插件提供了便捷解决方案，但您也可以根据项目需求实现自定义处理

故障排除

确认API凭证是否正确
检查网络连接
确保使用TTS功能时，所有音频处理库(如Runtime Audio Importer)已正确安装
处理TTS响应数据时验证是否使用了正确的音频格式
对于流式TTS，确保正确处理音频数据块
