protobufs 格式的原始解码器 [英] raw decoder for protobufs format

问题描述

我想找到一种方法将二进制 protobuf 消息转换为包含数据的人类可读描述，而无需使用 .proto 文件.

I'd like to find a way to convert a binary protobuf message into a human readable description of the contained data, without using the .proto files.

背景是我有一个 .proto 消息，它被 Android 上的解析器拒绝，但不完全清楚原因.我可以手动浏览消息，但它相当乏味.

The background is that I have a .proto message that it being rejected by the parser on Android, but it's not entirely clear why. I could go through the message by hand, but it's rather tedious.

我尝试了 protoc --decode_raw，但它只是给出错误无法解析输入.".我在谷歌上搜索希望/期望有人会做一个很好的网络实用程序，可以做到这一点，但没有发现任何明显的东西.

I tried protoc --decode_raw, but it just gives the error "Failed to parse input.". I google hoping/expecting someone would have done a nice web utility that might do this, but haven't found anything obvious.

我只是希望得到一些输出，如:

I'm just hoping to get some output like:

field 1: varint: 128
field 4: string: "foo"

欢迎任何指向正确方向的指针！

Any pointers in the right direction would be most welcome!

推荐答案

你可以尝试通过wireshark插件强制它，或者你可以借用一些实现的阅读器"部分(我知道我将如何做到这一点例如，在 C# 中，但我怀疑这就是您的意思).

You could try forcing it through the wireshark plugin, or you could probably borrow the "reader" part of some of the implementations (I know how I would do this in C#, for example, but I doubt that is what you meant).

但是，要小心 - 协议缓冲区中的字符串并不真正意味着字符串" - 它可能是:

However, be cautious - string in protocol buffers doesn't really mean "string" - it could be:

• 一个 UTF-8 字符串
• 原始 BLOB 的任意数据
• 子消息
• 一个打包"的数组
• (可能是我忘记的其他东西)
