如何在wireshark Lua脚本中显示UTF-8数据

Question

我一直试图用UTF-8来表示日语解码中的二进制，但仍然没有找到正确的方法。这是密码。

vps_proto = Proto("vps", "VPS Packet")
Name_F = ProtoField.string("Name", "Name")
vps_proto.fields = {Name_F}

function RequestAccountPayloadParse(decoded_buf, pinfo, subtree)
    local PayloadNameRange = decoded_buf(0, 20)
    local PayloadName = PayloadNameRange:string(ENC_UTF_8)

    local payloadPacTree = subtree:add(decoded_buf(), pinfo, subtree)
    payloadPacTree:set_text("Payload")

    payloadPacTree:set_text:add(Name_F, PayloadNameRange, PayloadName)
end

“wireshark”中的结果显示，没有如下所示的适当的日语字符，

Payload
    Name: \350\213\227\...

这应该是

Payload
    Name: 山田太郎...

你能找出那个问题吗？谢谢。

Answer 1

试着替换这些行：

Name_F = ProtoField.string("Name", "Name")

local PayloadName = PayloadNameRange:string(ENC_UTF_8)

有了这些：

Name_F = ProtoField.string("vps.Name", "Name", base.UNICODE)

local PayloadName = PayloadNameRange:raw()
