)

func main() {
	// Create an OSSClient instance.
	client, err := oss.New("<yourEndpoint>", "<yourAccessKeyId>", "<yourAccessKeySecret>")
	if err ! = nil {
		fmt.Println("Error:", err)
		os.Exit(-1)
	}

	// Obtain the bucket.
	bucket, err := client.Bucket("<yourBucketName>")
	if err ! = nil {
		fmt.Println("Error:", err)
		os.Exit(-1)
	}

	// Determine whether the specified object exists.
	isExist, err := bucket.IsObjectExist("<yourObjectName>")
	if err ! = nil {
		fmt.Println("Error:", err)
		os.Exit(-1)
	}
	fmt.Println("Exist:", isExist)
}
