If you wish to monitor resource changes in TOS in real time, you can configure event notification rules using the Go SDK.
Precautions
- Only the bucket Owner can create event notification services.
- Setting up event notifications requires reliance on function services. You must first create and publish a function service in Volcengine. For detailed instructions, refer to Create Function and Publish Function.
Configure Event Notifications
The following code is used to configure event notification rules for the bucket.
package main
import (
"context"
"fmt"
"github.com/volcengine/ve-tos-golang-sdk/v2/tos"
)
func checkErr(err error) {
if err != nil {
if serverErr, ok := err.(*tos.TosServerError); ok {
fmt.Println("Error:", serverErr.Error())
fmt.Println("Request ID:", serverErr.RequestID)
fmt.Println("Response Status Code:", serverErr.StatusCode)
fmt.Println("Response Header:", serverErr.Header)
fmt.Println("Response Err Code:", serverErr.Code)
fmt.Println("Response Err Msg:", serverErr.Message)
} else {
fmt.Println("Error:", err)
}
panic(err)
}
}
func main() {
var (
accessKey = os.Getenv("TOS_ACCESS_KEY")
secretKey = os.Getenv("TOS_SECRET_KEY")
endpoint = "https://tos-cn-beijing.volces.com"
region = "cn-beijing"
bucketName = "*** Provide your bucket name ***"
ctx = context.Background()
)
client, err := tos.NewClientV2(endpoint, tos.WithRegion(region), tos.WithCredentials(tos.NewStaticCredentials(accessKey, secretKey)))
checkErr(err)
input := &tos.PutBucketNotificationInput{Bucket: bucketName,
CloudFunctionConfigurations: []tos.CloudFunctionConfiguration{
{
ID: "TestNotification",
Events: []string{"tos:ObjectCreated:Put"},
Filter: tos.Filter{Key: tos.FilterKey{Rules: []tos.FilterRule{{
Name: "prefix",
Value: "test-",
}, {
Name: "suffix",
Value: "-ci",
}}}},
CloudFunction: "Provide the ID of your cloud function",
},
}}
out, err := client.PutBucketNotification(ctx, input)
checkErr(err)
fmt.Println("Request ID:", out.RequestID)
}
Get Event Notifications
The following code is used to retrieve the event notification rules of a bucket.
package main
import (
"context"
"fmt"
"github.com/volcengine/ve-tos-golang-sdk/v2/tos"
)
func checkErr(err error) {
if err != nil {
if serverErr, ok := err.(*tos.TosServerError); ok {
fmt.Println("Error:", serverErr.Error())
fmt.Println("Request ID:", serverErr.RequestID)
fmt.Println("Response Status Code:", serverErr.StatusCode)
fmt.Println("Response Header:", serverErr.Header)
fmt.Println("Response Err Code:", serverErr.Code)
fmt.Println("Response Err Msg:", serverErr.Message)
} else {
fmt.Println("Error:", err)
}
panic(err)
}
}
func main() {
var (
accessKey = os.Getenv("TOS_ACCESS_KEY")
secretKey = os.Getenv("TOS_SECRET_KEY")
endpoint = "https://tos-cn-beijing.volces.com"
region = "cn-beijing"
bucketName = "*** Provide your bucket name ***"
ctx = context.Background()
)
client, err := tos.NewClientV2(endpoint, tos.WithRegion(region), tos.WithCredentials(tos.NewStaticCredentials(accessKey, secretKey)))
checkErr(err)
out, err := client.GetBucketNotification(ctx, &tos.GetBucketNotificationInput{Bucket: bucketName})
checkErr(err)
fmt.Println("Request ID:", out.RequestID)
for _, conf := range out.CloudFunctionConfigurations {
fmt.Println("Cloud Function Configuration ID:", conf.ID)
fmt.Println("Cloud Function Configuration Events", conf.Events)
fmt.Println("Cloud Function Configuration Filter", conf.Filter)
fmt.Println("Cloud Function Configuration CloudFunction", conf.CloudFunction)
}
}
