step

1. sync first and second root path

curl -H "Content-Type: application/json" -X POST -d '{"token":"Y2xhc3Nub3Rmb3VuZC5jb20uY24="}' "http://127.0.0.1:8000/getroots"
##For deep directories, special handling is required,such as:
curl -H "Content-Type: application/json" -X POST -d '{"token":"Y2xhc3Nub3Rmb3VuZC5jb20uY24=","root":"https://repo1.maven.org/maven2/com/google/apis/"}' "http://127.0.0.1:8000/getdeeproot"

2. sync all jar path

curl -H "Content-Type: application/json" -X POST -d '{"token":"Y2xhc3Nub3Rmb3VuZC5jb20uY24="}' "http://127.0.0.1:8000/getalljars"

3. download lasteast jar and parse classes

curl -H "Content-Type: application/json" -X POST -d '{"headwords": "a,b,d,e,f,g,h,i","token":"Y2xhc3Nub3Rmb3VuZC5jb20uY24="}' "http://127.0.0.1:8000/parseclasses"
