# Simple cURL wrapper to manage nicely error handling:
|
|
#
|
|
# * In case of success, just read body from stdout
|
|
# * In case of HTTP error (status >= 400), first stderr contains "HTTP status: XXX", then body
|
|
# * In case of other error, just print cURL error on stderr
|
|
#
|
|
# This function requires a temporary file. It's created under ${TEMP_DIR} if defined and not empty.
|
|
# Otherwise, it relies on `mktemp` defaults.
