The nginx.Parser does not support fields or contexts in the format of Lua Scripts currently. You can consider first to separate Lua Scripts into script files and set a parser.Key for it. The sample configuration is as follows:

...
location /test/ {

        set_by_lua_block_file ../block.lua;
...

At present, I am reconstructing the Heimdallr-reborn project. After completion, I will consider allowing Bifrost to support custom format fields or contexts such as Lua Scripts; Or if you have a better solution, you are welcome to submit a PR.
