Is there a way to get the size of a
curl
request programmatically?E.g. if I do
curl 'http://www.example.com/url' \ -H 'Cookie: cookie=cookiedata;' \ -H 'X-CSRFToken: csrffake' \ --data 'example=moredata \ --compressed
I want to know how big my sent request is?
Answer
Ok after some man curl
digging, I think I’ve found out the answer, though I’m not 100% sure about it’s validity:
-w, --write-out <format> Defines what to display on stdout after a completed and successful operation. [...] The variables present in the output format will be substituted by the value or text that curl thinks fit, as described below. All variables are specified as %{variable_name} and to output a normal % you just write them as %%. [...] size_request The total amount of bytes that were sent in the HTTP request. size_upload The total amount of bytes that were uploaded.
That means adding a -w '%{size_request} %{size_upload}'
and then adding the resulting numbers in the output after the request will give you the request size in total.
