Abnormal image detection is used to identify whether an image contains suspicious files other than the image itself, such as MPEG-TS files. If an image file containing suspicious content is detected, you may process the image file to prevent your storage space from being misused by illicit image hosting services. This article describes how to perform abnormal image detection using the TOS Go SDK.
Precautions
- The size of the original image for detection must not exceed 20MB.
- Abnormal image detection is supported only for files in JPG, JPEG, PNG, BMP, GIF, and pure TS video stream file formats.
- The abnormal image detection function is billed based on the number of processing instances. For detailed information, please refer to Data Processing Fees.
Sample Code
The following code demonstrates how to detect abnormal images.
package main
import (
"context"
"encoding/json"
"fmt"
"github.com/volcengine/ve-tos-golang-sdk/v2/tos"
"io/ioutil"
)
type ImageInspectResponse struct {
PicSize int `json:"picSize"`
PicType string `json:"picType"`
Suspicious bool `json:"suspicious"`
SuspiciousBeginByte int `json:"suspiciousBeginByte"`
SuspiciousEndByte int `json:"suspiciousEndByte"`
SuspiciousSize int `json:"suspiciousSize"`
SuspiciousType string `json:"suspiciousType"`
}
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 ***"
imageKey = "image.png"
ctx = context.Background()
)
client, err := tos.NewClientV2(endpoint, tos.WithRegion(region), tos.WithCredentials(tos.NewStaticCredentials(accessKey, secretKey)))
checkErr(err)
style := "image/inspect"
out, err := client.GetObjectV2(ctx, &tos.GetObjectV2Input{Bucket: bucketName, Key: imageKey, Process: style})
checkErr(err)
defer out.Content.Close()
fmt.Println("ContentType:", out.ContentType)
info, err := ioutil.ReadAll(out.Content)
checkErr(err)
imageInspect := &ImageInspectResponse{}
err = json.Unmarshal(info, imageInspect)
checkErr(err)
fmt.Println("picSize:", imageInspect.PicSize, " picType:", imageInspect.PicType, " suspicious:", imageInspect.Suspicious)
}
