我试图了解 HTTP/2 协议(protocol)压缩数据字段的方式。我在 rfc 中没有找到算法。我知道它是一个二进制协议(protocol)。
我正在寻找一种将二进制协议(protocol)恢复为人类可读内容的方法。我认为它就像写在标题中的gzip,但没有人有我可以查找二进制协议(protocol)引用的来源?

最佳答案
HTTP/2 响应的响应正文被压缩(或不压缩)与使用 HTTP/1 的方式完全相同:Accept-Encoding:
在请求和 Content-Encoding:
在回应中。 HTTP/2 对正文的压缩没有任何新的作用,只有在 HTTP/1 中根本没有压缩的 header 。
