STEP 1: Read the configuration settings from environment variables.
openAIAPIKey := os.Getenv("AZURE_OPENAI_API_KEY")
if openAIAPIKey == "" {
openAIAPIKey = "<insert your OpenAI API key here>"
}
openAIEndpoint := os.Getenv("AZURE_OPENAI_ENDPOINT")
if openAIEndpoint == "" {
openAIEndpoint = "<insert your OpenAI endpoint here>"
}
openAIChatDeploymentName := os.Getenv("AZURE_OPENAI_CHAT_DEPLOYMENT")
if openAIChatDeploymentName == "" {
openAIChatDeploymentName = "<insert your OpenAI chat deployment name here>"
}
openAISystemPrompt := os.Getenv("AZURE_OPENAI_SYSTEM_PROMPT")
if openAISystemPrompt == "" {
openAISystemPrompt = "You are a helpful AI assistant."
}
STEP 2: Validate the environment variables.
if openAIEndpoint == "" || openAIAPIKey == "" || openAIChatDeploymentName == "" || openAISystemPrompt == "" {
fmt.Println("Please set the environment variables.")
os.Exit(1)
}
STEP 3: Initialize the helper class with the configuration settings.
chat, err := NewOpenAIChatCompletionsExample(openAIEndpoint, openAIAPIKey, openAIChatDeploymentName, openAISystemPrompt)
if err != nil {
log.Fatalf("ERROR: %s", err)
}
STEP 4: Obtain user input, use the helper class to get the assistant's response, and display responses as they are received.
for {
fmt.Print("User: ")
input, _ := getUserInput()
if input == "exit" || input == "" {
break
}
response, err := chat.GetChatCompletions(input)
if err != nil {
log.Fatalf("ERROR: %s", err)
}
fmt.Printf("Assistant: %s\n\n", response)
}

STEP 1: Create the client and initialize chat message history with a system message.
client, err := azopenai.NewClientWithKeyCredential(openAIEndpoint, keyCredential, nil)
if err != nil {
return nil, err
}
messages := []azopenai.ChatRequestMessageClassification{
&azopenai.ChatRequestSystemMessage{
Content: &openAISystemPrompt,
},
}
STEP 2: When the user provides input, add the user message to the chat message history.
func (chat *OpenAIChatCompletionsExample) GetChatCompletions(userPrompt string) (string, error) {
chat.options.Messages = append(chat.options.Messages, &azopenai.ChatRequestUserMessage{Content: azopenai.NewChatRequestUserMessageContent(userPrompt)})
STEP 3: Send the chat message history to the OpenAI Chat API and process the response.
resp, err := chat.client.GetChatCompletions(context.TODO(), *chat.options, nil)
if err != nil {
return "", err
}
STEP 4: Add the assistant's response to the chat message history and return the response.
