所以我写了我只能称之为令人敬畏的解剖器。它没有多大作用,但它极大地提高了我的工作效率。
我唯一的问题是我暴露了一些偏好,他们不会坚持通过wireshark关闭/启动。
IE :
先决条件:Lua 脚本必须在插件目录中...
- 打开wireshark,编辑>首选项>协议> http.queryparameters...
- 将 Param1 值设置为“aaa”,单击“确定”。(它会正确影响解剖。)
- 关闭wireshark,重新开始,值又是别的东西。
我的解剖器:
-- Written by Eitam Doodai
-- trivial postdissector example
-- declare some Fields to be read
full_uri_from_request = Field.new("http.request.full_uri")
-- declare our (pseudo) protocol
http_query_params_proto = Proto("http.query_parameters","HTTP Query Parameters Postdissector")
-- create the fields for our "protocol"
query_param1 = ProtoField.string("http.query_parameters.param1","PARAM1")
query_param2 = ProtoField.string("http.query_parameters.param2","PARAM2")
query_param3 = ProtoField.string("http.query_parameters.param3","PARAM3")
-- add the field to the protocol
http_query_params_proto.fields = {query_param1}
http_query_params_proto.fields = {query_param2}
http_query_params_proto.fields = {query_param3}
-- Add prefs
local p1 = http_query_params_proto.prefs
p1.value1 = Pref.string ("Param1 Value", "123", "Param key to extract")
p1.value2 = Pref.string ("Param2 Value", "456", "Param key to extract")
p1.value3 = Pref.string ("Param3 Value", "789", "Param key to extract")
-- create a function to "postdissect" each frame
function http_query_params_proto.dissector(buffer,pinfo,tree)
-- obtain the current values the protocol fields
local full_uri_value = full_uri_from_request()
if full_uri_value then
local value = tostring(full_uri_value)
local subtree = tree:add(http_query_params_proto,"Query Param1")
local subtree = tree:add(http_query_params_proto,"Query Param2")
local subtree = tree:add(http_query_params_proto,"Query Param3")
_, _, query_param1_str = string.find(value,p1.value1 .. "=([^&]+)")
_, _, query_param2_str = string.find(value,p1.value2 .. "=([^&]+)")
_, _, query_param3_str = string.find(value,p1.value3 .. "=([^&]+)")
if query_param1_str then
subtree:add(query_param1,query_param1_str)
end
if query_param2_str then
subtree:add(query_param2,query_param2_str)
end
if query_param3_str then
subtree:add(query_param3,query_param3_str)
end
end
end
-- register our protocol as a postdissector
register_postdissector(http_query_params_proto)
