	// Ensure it's a POST request
	if r.Method != http.MethodPost {
		http.Error(w, "Method not allowed", http.StatusMethodNotAllowed)
		return
	}

	// Read the request body
	body, err := ioutil.ReadAll(r.Body)
	if err != nil {
		http.Error(w, "Error reading request body", http.StatusInternalServerError)
		return
	}

	// Unmarshal the callback event
	var event callback.Event
	err = json.Unmarshal(body, &event)
	if err != nil {
		http.Error(w, "Error unmarshalling callback event", http.StatusBadRequest)
		return
	}

	// Process the event based on its type
	sfmt.Printf("Received callback event: %+v\n", event)

	s// Example: Respond to text messages
	if event.Type == "text" {
		textEvent, ok := event.Data.(callback.TextEvent)
		if ok {
			fmt.Printf("Received text message from %s: %s\n", textEvent.Sender, textEvent.Content)
			// TODO: Implement your response logic here
		}
	}

	// Respond with success
	w.WriteHeader(http.StatusOK)
}

func main() {
	http.HandleFunc("/callback", handleCallback)
	fmt.Println("Starting callback server on :8080")
	
	err := http.ListenAndServe(":8080", nil)
	if err != nil {

### Handle Incoming Messages in Go

Source: https://github.com/vimsucks/wxwork-bot-go/blob/master/README.md

This code example shows how to set up a message handler for incoming messages in a WeChat Work bot built with Go. It defines a function that will be called whenever the bot receives a message, allowing for custom processing and responses.

```go
package main

import (
	"fmt"
	"github.com/wxwork/wxwork-go/sdk"

func main() {
	// ... (bot initialization as shown in the previous example)

	// Register a message handler
	bot.RegisterHandler(event.NewMessageHandler(handleMessage))

	fmt.Println("Message handler registered.")

	// Start the bot to listen for messages
	// bot.Start() // This would typically be called to run the bot
}

func handleMessage(msg *event.Message) {
	fmt.Printf("Received message: Type=%s, Content=%s\n", msg.MsgType, msg.Content)

	// Process the message and send a response if needed
	// For example, echo the message back:
	// response := &event.Message{
	// 	ToUser: msg.FromUser,
	// 	MsgType: "text",
	// 	Content: "You said: " + msg.Content,
	// }
	// bot.Send(response)
}

)

func main() {
	// Replace with your actual bot token
	botToken := "YOUR_BOT_TOKEN"
	wxbot := bot.NewBot(botToken)

	// Upload a voice file to get a media ID
	// Replace "path/to/your/voice.amr" with the actual file path
	mediaID, err := wxbot.UploadMedia("path/to/your/voice.amr", bot.MediaTypeVoice)
	if err != nil {
		log.Fatalf("Failed to upload voice: %v\n", err)
	}

	// Create a new voice message using the media ID
	// To: The recipient's UserID or PartyID or TagID
	oUser := "USERID1"

	voiceMessage := bot.NewVoiceMessage(toUser, mediaID)

	// Send the message
	err = wxbot.SendMessage(voiceMessage)
	if err != nil {
		log.Fatalf("Failed to send voice message: %v\n", err)

### Get WeChat Work Bot Access Token in Go

Source: https://github.com/vimsucks/wxwork-bot-go/blob/master/README.md

This Go function is responsible for obtaining an access token from the WeChat Work API. It makes an HTTP GET request to the token endpoint, likely using a CorpID and Secret, and parses the response to extract the token.

```go
func (b *Bot) GetAccessToken() (string, error) {
	url := fmt.Sprintf("%s/gettoken?corpid=%s&corpsecret=%s", b.BaseURL, b.CorpID, b.CorpSecret)

	resp, err := http.Get(url)
	if err != nil {
		return "", fmt.Errorf("failed to get access token: %w", err)
	}

	defer resp.Body.Close()

	var tokenResponse struct {
		AccessToken string `json:"access_token"`
		ExpiresIn   int    `json:"expires_in"`
		ErrCode     int    `json:"errcode"`
		ErrMsg      string `json:"errmsg"`
	}

	if err := json.NewDecoder(resp.Body).Decode(&tokenResponse); err != nil {
		return "", fmt.Errorf("failed to decode token response: %w", err)
	}

	if tokenResponse.ErrCode != 0 {
		return "", fmt.Errorf("failed to get access token: %s (errcode: %d)", tokenResponse.ErrMsg, tokenResponse.ErrCode)
	}

	return tokenResponse.AccessToken, nil
}
```

		// Process the message and potentially send a reply
		reply := bot.NewTextMessage(msg.FromUserName, "Received your message!")
		botClient.Send(reply)
	})

	// Start the bot server to listen for incoming webhook events
	log.Fatal(botClient.Start(":8080"))
}
```

)

func main() {
	// Replace with your actual bot token
	botToken := "YOUR_BOT_TOKEN"
	wxbot := bot.NewBot(botToken)

	// Create a new text message for a group chat
	// To: The Group Chat ID (e.g., "wrk_xxxxxxxxxxxx")
	// Content: The text content of the message
	toGroupChatID := "wrk_xxxxxxxxxxxx"
	messageContent := "Hello group members!"

	textMessage := bot.NewTextMessage(toGroupChatID, messageContent)

	// Send the message
	err := wxbot.SendMessage(textMessage)
	if err != nil {
		log.Fatalf("Failed to send message to group chat: %v\n", err)
	}

	log.Println("Message sent to group chat successfully!")
}

### Go WeChat Work Bot Image Message Sending

Source: https://github.com/vimsucks/wxwork-bot-go/blob/master/README.md

This snippet demonstrates how to send an image message using the wxwork-bot-go library. It requires the image to be uploaded first to get a media ID.

```Go
package main

import (
	"log"

	"github.com/wxwork-bot-go/pkg/bot"
)

func main() {
	// Replace with your actual bot token
	botToken := "YOUR_BOT_TOKEN"
	wxbot := bot.NewBot(botToken)

	// Upload an image file to get a media ID
	// Replace "path/to/your/image.png" with the actual file path
	mediaID, err := wxbot.UploadMedia("path/to/your/image.png", bot.MediaTypeImage)
	if err != nil {
		log.Fatalf("Failed to upload image: %v\n", err)
	}

	// Create a new image message using the media ID
	// To: The recipient's UserID or PartyID or TagID
	toUser := "USERID1"

	imageMessage := bot.NewImageMessage(toUser, mediaID)

	// Send the message
	err = wxbot.SendMessage(imageMessage)
	if err != nil {
		log.Fatalf("Failed to send image message: %v\n", err)

	bot.SendText("user_id_123", "Hello from the bot!")

	// Send an image message (requires media ID)
	// Assuming you have a media ID for an uploaded image
	bot.SendImage("user_id_123", "media_id_abc")

	// Send a file message (requires media ID and filename)
	bot.SendFile("user_id_123", "media_id_xyz", "document.pdf")

	// Send a message to a group chat
	bot.SendText("group_chat_id_456", "This is a message to the group.")
}

```
