How can I rewrite this CURL multipart/form-data request without using -F?
curl, http, multipartform-data
Solution
Solved:
curl \
-X POST \
-H "Content-Type: multipart/form-data; boundary=----------------------------4ebf00fbcf09" \
--data-binary @test.txt \
http://localhost:3000/test
Where `test.txt` contains the following text, and most importantly has CRLF (\r\n) line endings:
------------------------------4ebf00fbcf09
Content-Disposition: form-data; name="example"
test
------------------------------4ebf00fbcf09--
Notes: it is important to use `--data-binary` instead of plain old `-d` as the former preserves the line endings (which are very important). Also, note that the boundary in the body starts with an extra `--`.
I'm going to repeat it because it's so important, but that request-body file must have CRLF line endings. A multi-platform text editor with good line-ending support is jEdit (how to set the line endings in jEdit).
If you're interested in how I worked this out (debugging with a Ruby on Rails app) and not just the final solution, I wrote up my debugging steps on my blog.
Problem
How can I rewrite the following CURL command, so that it doesn't use the `-F` option, but still generates the exact same HTTP request? i.e. so that it passes the multipart/form-data in the body directly. ``` curl -X POST -F example=test http://localhost:3000/test ```
