指定bucket 初始化Bucket类
@note SDK会自动获取bucket的信息,包括读取权限等并进行缓存
如需在后台修改了bucket信息请重新初始化Client
@param bucket_name [String] bucket名称
如果在初始化时的配置中设置了default_bucket则该字段可以为空,会获取默认的bucket
@return [COS::Bucket]
@raise [ClientError] 未指定bucket @raise [ServerError] bucket不存在
# File lib/cos/client.rb, line 48 def bucket(bucket_name = nil) unless @cache_buckets[bucket_name] # 缓存bucket对象 @cache_buckets[bucket_name] = Bucket.new(self, bucket_name) end @cache_buckets[bucket_name] end
