Python中使用BaseHTTPServer编写简易HTTP服务器,Response有时缺少头部,求大佬指点!
就是一个很简单的 HTTP 服务器,响应任意 GET 请求,返回一个文件
服务端用 clumsy 模拟乱序环境,乱序 10%
然后在客户端抓包发现有时候服务端的 Response 没有 HTTP 头,不知道为什么……
是 python 有 bug 还是我写的代码有问题?求大佬指点
有头部的流
GET /122879/122879.bat HTTP/1.1
Host: 200.200.89.77:8832
User-Agent: python-requests/2.18.4
Accept-Encoding: gzip, deflate
Accept: */*
Connection: keep-alive
HTTP/1.0 200 OK
Server: BaseHTTP/0.6 Python/3.7.0

说明没走到 set header 逻辑里,需要打日志了
散了散了,Wireshark 有 bug,导致乱序包重组失败,实际是有 HTTP 头的
首先别怀疑编程语言有 bug
我太相信 wireshark 了
我总以为这么历史悠久的软件怎么会有 BUG 呢?
他还真有
