这应该是全网首篇，c#调用Betalgo.OpenAI.GPT3库，实现简单的gpt连贯对话

网上找了半天完整版的调用Betalgo.OpenAI.GPT3的方法，但都不够完整，研究了一下源库的属性和方法，参考python的openai库的调用方法，我找到了以下方法实现完整对话：

static async Task Main(string[] args)

{

Console.WriteLine("****************************");

OpenAIService openAIService = GetService();

ChatCompletionCreateResponse completionResult = new ChatCompletionCreateResponse();

ChatCompletionCreateRequest cr = new ChatCompletionCreateRequest

{

Messages = new List

{

//ChatMessage.FromSystem("You are a helpful assistant."),

//ChatMessage.FromUser("Who won the world series in 2020?"),

//ChatMessage.FromAssistant("The Los Angeles Dodgers won the World Series in 2020."),

ChatMessage.FromUser(Console.ReadLine())

},

Model = Models.ChatGpt3_5Turbo,

MaxTokens = 1000//optional

};

await GetResult(openAIService, completionResult, cr);//注意，这里使用异步，我们下文再说

//Task.WaitAll(Task.Delay(1000));

}

//这里定义一个异步方法，因为原库的openAIService.ChatCompletion.CreateCompletion()是一个异步方法，我在原库的GitHub社区看到有人建议在方法名后面加一个async强调异步，看来不少人中招了，把它当同步方法用，哈哈哈。

private static async Task GetResult(OpenAIService openAIService, ChatCompletionCreateResponse completionResult, ChatCompletionCreateRequest cr)

{

try

{

completionResult = await openAIService.ChatCompletion.CreateCompletion(cr);

}

catch (Exception e)

{

Console.WriteLine(e);

}

if (completionResult.Successful)

{

Console.WriteLine(completionResult.Choices.First().Message.Content);

cr.Messages.Add(ChatMessage.FromUser(Console.ReadLine()));

await GetResult(openAIService, completionResult,cr);//维持现有会话不变，继续问答

}

}

public static OpenAIService GetService()

{

var handler = new HttpClientHandler()//这里使用了代理

{

Proxy = new WebProxy("192.168.1.67", 1082),

UseProxy = true

};

var client = new HttpClient(handler);

var openAiService = new OpenAIService(new OpenAiOptions()

{

ApiKey = "sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxk", /*哦对了，我这里只是简单的设置了一下apikey,建议采用依赖注入，这样更安全*/

}, client);

return openAiService;

}

}
