wireshark的基本使用，过滤请求，过滤数据，追踪数据

dump出来文件

wireshark 过滤条件

http.request and http contains "/api/serve/predict"

frame contains "输入数据中缺少以下变量"

frame contains ""code":500"

(frame contains ":500") && (json.path_with_value == " 400: 发生错误")

#成功抓取

sudo tcpdump -i any -A -s 0 -l 'tcp port 8080' | grep --line-buffered -E "(POST|GET|HTTP/|Cookie:|Set-Cookie:|/api/torchserve/predict)"

sudo tcpdump -i any -A -s 0 -l 'tcp port 8080' | grep --line-buffered -E "(POST|GET|HTTP/|Cookie:|Set-Cookie:|TE1111B)"

sudo tcpdump -i any -A -s 0 -l 'tcp port 8080' | grep --line-buffered -E "(POST|GET|HTTP/|Cookie:|Set-Cookie:|TE1111B|HTTP/1.1 200)"

筛选出来后右键-追踪流-HTTP-stream 就可以看到http的请求参数和返回参数了
