错误处理

异常处理

在调用相关的方法之后，都有一个返回值，而其有一个判断是否执行成功的方法：IsSuccess(), 如果执行成功，那么返回true，反之false 如果失败，那么可以通过下面代码打印出错信息：

std::cout << "DeleteObject error: " << delete_object_outcome.GetError().GetExceptionName() << " " << delete_object_outcome.GetError().GetMessage() << std::endl;

示例代码

Aws::S3::Model::DeleteObjectRequest object_request;
object_request.WithBucket(bucketName).WithKey(objectName);
auto delete_object_outcome = s3Client.DeleteObject(object_request);
if (delete_object_outcome.IsSuccess())
{
    std::cout << "Done!" << std::endl;
}
else
{
    std::cout << "DeleteObject error: " <<
    delete_object_outcome.GetError().GetExceptionName() << " " <<
    delete_object_outcome.GetError().GetMessage() << std::endl;
}
