Thrift 是一種接口描述語言和二進制通訊協議。之前也沒接觸過,最近有個項目須要創建自動化測試,這個項目之間的微服務都是經過 Thrift 進行通訊的,而後寫自動化腳本以前研究了一下。python
須要定義一個xxx.thrift的文件, 來生成各類語言的代碼,生成以後咱們的服務提供者和消費者,都須要把代碼引入,服務端把代碼實現,消費者直接使用API的存根,直接調用。apache
和 http 相比,同屬於應用層,走 tcp 協議。Thrift 優點在於發送一樣的數據,request包 和 response包 要比 http 小不少,在總體性能上要優於 http 。json
環境準備:windows
1.首先使用 thrift 以前須要定義一個 .thrift 格式的文件,好比 test.thrift服務器
service Transmit { string sayMsg(1:string msg); string invoke(1:i32 cmd 2:string token 3:string data) }
而後運行命令:thrift-0.9.3.exe -gen py test.thrift 生成 python 代碼socket
生成以下結構
tcp
2.而後將生成的 python 代碼 和 文件,放到新建的 python 項目中。完成後先運行服務器代碼。ide
