前言
現在微服務很流行，很多的語言都有自己的rpc框架，在同一框架內的微服務之間通信很方便，筆者工作時用到的框架是hyperf，自帶jsonrpc、grpc組件，grpc用起來略感繁瑣，調試起來也不方便，因此選用jsonrpc-http，損失些許通信成本在可接受範圍之內，能用postman調試實在是太方便了。
隨着業務和團隊的不斷髮展，開始有多語言開發需求，我們的另一個項目是用go搭建的，hyperf與go之間也打算用jsonrpc，go自帶jsonrpc包，但是是jsonrpc1.0的，與hyperf不兼容，經過努力，找到一個jsonrpc2.0的包（go-jsonrpc），與hyperf完美兼容。
