对于 Blob，前端开发中可能比较少遇到；数据库中可使用 Blob 概念，例如 Mysql 存储二进制数据的类型就是 Blob，也就是说图片可存储于数据库中，以二进制格式存储 利用

2.3 Serialization:type to format conversion If an object can be represented in multiple possible output formats, serializers SHOULD use the format which represents the data in the smallest number of bytes. 2.4 Deserialization: format to type conversion 三、为什么MessagePack比json序列化使用的字节流更少...

Blob 提供 API 来重置大多数状态,以避免不得不释放并重新创建状态。 本示例利用了这一点,尽可能重用通道和请求状态,并且仅在超过某些阈值时创建或销毁状态。 可以在 CChannelManager 中找到与通道管理相关的代码。 主消息处理循环位于 CRequest 中。 该类包含异步 Sapphire 消息处理循环所需的独立于应用程序的状态...
