使用

1. 在ConfigureService方法中添加依赖注入

public void ConfigureServices(IServiceCollection services, IConfiguration config){
    //....
    
    // Ensure HttpContext injected. It will be accessed in Chat service.
    services.AddHttpContextAccessor();

    // inject image storage provider
    services.AddTransient<IImageStorageProvider, LocalImageStorageProvider>();
    // inject chat data provider
    // for baidu chat caching
    services.AddTransient<IChatDataProvider<ChatMessageBase, string>, ChatDataProvider<ChatMessageBase, string>>();
    // for chatgpt
    services.AddTransient<IChatDataProvider<OpenAIChatMessage, List<OpenAIMessageContent>>, ChatDataProvider<OpenAIChatMessage, List<OpenAIMessageContent>>>();
    
    // inject service
    services.AddChatGPT(config);
    services.AddWenxinworkshop(config);
    services.AddErnieVilg(config);

    //...
}

2. Have fun!
