通过MQTT或HTTP交换的最轻量，最有效的消息有效载荷格式是什么? [英] Which is the most lightweight and efficient message payload format to exchange over MQTT or HTTP?

问题描述

我正在从事一个项目，该项目需要在现场的边缘设备与服务器之间交换数据.由于这是一个复杂的体系结构，包含许多组件，因此在处理资源受限的设备时，对每个组件进行全面评估并使其优化和轻量化非常重要.

I am been working on a project where it is required to exchange data between the edge device on field and the server. As this is a complex architecture and contains a lot of components it is important that each and every component be evaluated thoroughly and make it optimized and lightweight as we are dealing with resource constrained device.

我大部分已经看到使用JSON作为消息有效负载.我只想知道有没有比JSON更轻巧和优化的更好的选择?

I have mostly seen the use of JSON for message payload. I just want to know are there any better options available than JSON which is more lightweight and optimized?

PS:重量轻意味着更少的计算能力，优化意味着更少的传输过程中数据损坏的可能性.

PS : Lightweight meaning less computing power, optimized meaning less chances of data corruption over transmission.

推荐答案

您总是可以自己滚动，但是除了适用于AWS IoT，Azure，Google IoT等的云专有方案外，我们还注意到这些非JSON基于:

You could always roll your own, but besides the cloud-proprietary schemes for AWS IoT, Azure, Google IoT, etc, we are aware of these non-JSON-based:

它们中的任何一个是否更轻便取决于您的确切要求.

Whether any of them is more light-weight depends on your EXACT requirements.
