1try {
2 await bosClient.headBucket(bucketName);
3} catch (bosResponse) {
4 // If the bucket does not exist, 404 will be returned, which needs to be judged in the exception
5 if (bosResponse.statusCode = 404) {
6 logger.info("this bucket is not exist");
7 } else {
8 logger.error(`errCode: ${bosResponse.error.code}`)
9 logger.error(`requestId: ${bosResponse.error.requestId}`)
10 logger.error(`errMessage: ${bosResponse.error.message}`)
