curl¶

download to current folder¶

-O keep remote filename

curl -O https://dev.com/api/hello.cpp

Sending a request with HEAD method (-I) to see the redirected url

curl -LI https://dev.com/api/hello.cpp

Sometimes downloadd file has 0 size. Need to tell curl to follow HTTP redirection by using -L/--location

curl -LO https://dev.com/api/hello.cpp

curl 'https://my.api/hello?id=1&name=dev' -H 'Accept: text/csv'
curl 'https://my.api/hello?id=1&name=dev' -H 'Accept: text/csv' -o my.csv
curl `https://my.api/hello -H "X-Custom-Header: value" -H "Content-Type: application/json"

post with header¶

curl -k -X POST https://dev.com/api/hello -H 'Content-Type: application/json' -d '{ "date": "2021-11-01", "value": 12 }'
