该插件将序列化的块跟踪数据存储到文件系统中，以便稍后通过HTTP RPC请求检索。
当将诸如区块浏览器和交易所等应用程序与EOSIO区块链集成时，用户可能需要区块链处理的action的完整副本，包括那些从执行智能合约和scheduled transacton产生的操作.
参见：
Trace Api Plugin | EOSIO Developer Docs
测试版本：image: eosio/eosio:release_2.2.x
trace配置
plugin=eosio::trace_api_plugin
trace-dir=traces
#trace-rpc-abi=eosio=abis/eosio.abi
trace-rpc-abi=eosio.token=abis/eosio.token.abi
trace-rpc-abi选项指定合约，以及合约abi文件的目录与文件名。如果指定了某个合约的abi，则再返回的action中会包含params（humanbeing readable）。
--trace-rpc-abi arg ABIs used when decoding trace RPC
responses.
There must be at least one ABI
specified OR the flag trace-no-abis
must be used.
ABIs are specified as "Key=Value" pairs
in the form <account-name>=<abi-def>
Where <abi-def> can be:
an absolute path to a file
containing a valid JSON-encoded ABI
a relative path from `data-dir` to a
file containing a valid JSON-encoded
ABI
