Apache-Thrift:带Javascript客户端的Python服务器

thrift python javascript

graille · 技术社区 · 6 年前

为了了解节俭是如何运作的,我从一个小测试项目开始。所以,我想使用一个带有基于浏览器的javascript客户端的python服务器。

服务器输出:

127.0.0.1 - - [04/Dec/2018 17:04:34] code 501, message Unsupported method ('OPTIONS')
127.0.0.1 - - [04/Dec/2018 17:04:34] "OPTIONS / HTTP/1.1" 501 -
