From 4771b2ead00ff95120ad9ef8ff3d2ff1754943be Mon Sep 17 00:00:00 2001 From: Tola Leng Date: Sat, 6 Sep 2025 20:42:22 +0700 Subject: [PATCH] feat: Implement Gotify notification service - The Gotify notification functionality has been implemented. The alert configuration channel will now use the `api_token` and `server_url` field for send to the Gotify API endpoint. --- .../service-operation/notification/gotify.go | 357 ++++++++++++++++++ .../service-operation/notification/manager.go | 1 + .../service-operation/notification/types.go | 1 + 3 files changed, 359 insertions(+) create mode 100644 server/service-operation/notification/gotify.go diff --git a/server/service-operation/notification/gotify.go b/server/service-operation/notification/gotify.go new file mode 100644 index 0000000..d63a395 --- /dev/null +++ b/server/service-operation/notification/gotify.go @@ -0,0 +1,357 @@ +package notification + +import ( + "bytes" + "encoding/json" + "fmt" + "net/http" + "strings" +) + +// GotifyService handles Gotify notifications +type GotifyService struct{} + +// NewGotifyService creates a new Gotify notification service +func NewGotifyService() *GotifyService { + return &GotifyService{} +} + +// GotifyPayload represents the payload for Gotify API +type GotifyPayload struct { + Message string `json:"message"` + Title string `json:"title,omitempty"` + Priority int `json:"priority,omitempty"` +} + +// GotifyResponse represents the response from Gotify API +type GotifyResponse struct { + ID int `json:"id"` + AppID int `json:"appid"` + Message string `json:"message"` + Title string `json:"title"` + Priority int `json:"priority"` + Date string `json:"date"` +} + +// SendNotification sends a notification via Gotify +func (gs *GotifyService) SendNotification(config *AlertConfiguration, message string) error { + // fmt.Printf("📱 [GOTIFY] Attempting to send notification...\n") + // fmt.Printf("📱 [GOTIFY] Config - API Token: %s, Server URL: %s, Notify Name: %s\n", + // maskToken(config.APIToken), config.ServerURL, config.NotifyName) + // fmt.Printf("📱 [GOTIFY] Message: %s\n", message) + + if config.APIToken == "" || config.ServerURL == "" { + return fmt.Errorf("Gotify API token and server URL are required") + } + + // Prepare the payload + payload := GotifyPayload{ + Message: message, + Title: config.NotifyName, // Use notify_name as the title + Priority: 5, // Default priority + } + + jsonData, err := json.Marshal(payload) + if err != nil { + // fmt.Printf("❌ [GOTIFY] JSON marshal error: %v\n", err) + return err + } + + // fmt.Printf("📱 [GOTIFY] Payload: %s\n", string(jsonData)) + // fmt.Printf("📱 [GOTIFY] Sending POST request to Gotify API...\n") + + // Construct the Gotify API URL + apiURL := strings.TrimRight(config.ServerURL, "/") + "/message?token=" + config.APIToken + + // Send the request to Gotify API + resp, err := http.Post(apiURL, "application/json", bytes.NewBuffer(jsonData)) + if err != nil { + // fmt.Printf("❌ [GOTIFY] HTTP error: %v\n", err) + return err + } + defer resp.Body.Close() + + // Check status code + if resp.StatusCode < 200 || resp.StatusCode >= 300 { + // fmt.Printf("❌ [GOTIFY] HTTP status error: %d\n", resp.StatusCode) + return fmt.Errorf("Gotify API error: HTTP %d", resp.StatusCode) + } + + // Parse the response + var gotifyResp GotifyResponse + if err := json.NewDecoder(resp.Body).Decode(&gotifyResp); err != nil { + // fmt.Printf("❌ [GOTIFY] Response decode error: %v\n", err) + return err + } + + // fmt.Printf("📱 [GOTIFY] API response: %+v\n", gotifyResp) + + // Check if the message was created successfully + if gotifyResp.ID == 0 { + // fmt.Printf("❌ [GOTIFY] API error: No message ID returned\n") + return fmt.Errorf("Gotify API error: message not created") + } + + // fmt.Printf("✅ [GOTIFY] Message sent successfully!
