Sending text file content as curl parameter from cmd, how to do?

Question

cmd/bat

There is a file.txt with content, this content needs to be passed as a parameter to the curl post request, how to do it?

It should turn out something like this, but I can’t figure out how to read the contents of the file into a parameter, or how to equate the parameter to the cmd variable
curl --data-binary "param1=A¶m2=B&text=Here is the content of the txt file" https:// example.com

Answer 1

Get into a variable using SET /Pand redirecting the input stream, or using FOR /F.
