请使用delphi语言写一段使用chatGPT的代码。

很抱歉，我是一个自然语言生成模型，无法编写Delphi代码。但是，您可以使用Delphi编写一个调用ChatGPT API的程序，实现与ChatGPT的交互。以下是一个简单的示例：

uses
  WinInet;

function GetResponseFromChatGPT(query: string): string;
const
  API_URL = 'https://api.openai.com/v1/engines/davinci-codex/completions';
  API_KEY = 'your_api_key_here';
var
  hInternet, hConnect, hRequest: HInternet;
  postdata, response: string;
  buffer: array[0..2047] of Char;
  bytesread: DWORD;
begin
  // Construct the API request payload
  postdata := '{"prompt": "' + query + '", "temperature": 0.5, "max_tokens": 50}';
  
  // Open the Internet connection
  hInternet := InternetOpen('ChatGPT', INTERNET_OPEN_TYPE_PRECONFIG, nil, nil, 0);
  if not Assigned(hInternet) then
    raise Exception.Create('Failed to open Internet connection');
  
  // Connect to the API server
  hConnect := InternetConnect(hInternet, 'api.openai.com', INTERNET_DEFAULT_HTTPS_PORT,
    nil, nil, INTERNET_SERVICE_HTTP, 0, 0);
  if not Assigned(hConnect) then
    raise Exception.Create('Failed to connect to API server');
  
  // Send the API request
  hRequest := HttpOpenRequest(hConnect, 'POST', PChar(API_URL), nil, nil, nil,
    INTERNET_FLAG_SECURE or INTERNET_FLAG_IGNORE_CERT_CN_INVALID or INTERNET_FLAG_IGNORE_CERT_DATE_INVALID, 0);
  if not Assigned(hRequest) then
    raise Exception.Create('Failed to send API request');
  
  if not HttpSendRequest(hRequest, nil, 0, PChar(postdata), Length(postdata)) then
    raise Exception.Create('Failed to send API request');
  
  // Read the API response
  response := '';
  repeat
    InternetReadFile(hRequest, @buffer, SizeOf(buffer), bytesread);
    if bytesread > 0 then
      response := response + Copy(buffer, 1, bytesread);
  until bytesread = 0;
  
  // Close the Internet connection
  InternetCloseHandle(hRequest);
  InternetCloseHandle(hConnect);
  InternetCloseHandle(hInternet);
  
  // Return the API response
  Result := response;
end;

这段代码将发送一个包含查询的API请求，并返回ChatGPT返回的响应。请注意，您需要替换`your_api_key_here`为您的OpenAI API密钥。此外，请确保在使用此代码之前已安装WinInet模块。
