I’m writing a script (for $NEW_PROJECT) which, due to my inability to figure out how to compile a certain key library on Dreamhost, runs SSH to a remote box (with public/private keys and a limitation on what that key can *actually* achieve) to perform an off-box process of some data.
After it’s all done, I am using curl to call the API of the project like this:
curl --fail -F "file=@`pwd`/file" -F "other=form" -F "options=are_set" http://user:password@server/api/function
Because I’m making a few calls against the API, I wrote a function like this:
function callAPI() {
API=$1
if [ "$2" != "" ]
then
API=$API/$2
fi
if [ "$3" != "" ]
then
API=$API/$3
fi
if [ "${OPTION}" != "" ]
then
FORM="${OPTION}"
else
FORM=""
fi
if [ $DEBUG == "1" ]
then
echo "curl --fail ${FORM} http://${USER}:**********@${SITE}/api/${API}"
fi
eval `curl --fail ${FORM} http://${USER}:${PASS}@${SITE}/api/${API} 2>/dev/null`
}
and then call it like this:
OPTION="-F \"file=@filename\" -F \"value=one\" -F \"value=two\""
callAPI function
For all the rest of my API calls (those which ask for data, rather than supply it, these calls work *fine*, but as soon as I tell it to post a form containing a file, it throws this error:
curl: (26) failed creating form post data
I did some digging around, and found that this means that the script can’t read from the file. The debug line, when run outside of the script processed the command perfectly, so what’s going on?
To be honest, in the end, I just copied the command into the body of the code, and I’m praying that I can figure out why I can’t compile this library on Dreamhost, before I need to work out why running that curl line doesn’t work from inside a function.
