bash - CURL inside script is not working as expected for VCD api's -


i trying curl vcloud director api. works fine when tried terminal, fails when tried inside bash script variable substitution.

this script not working:

token=" valid token" url="vcdurl" auth_header=\"x-vcloud-authorization:${token}\" curl -i -k -h "accept:application/*+xml;version=1.5" -h "${auth_header}" -x $url/api/vdc/7f252c90-eb3b-43c4-a5ef-458e5bf22c0e > test.txt echo `cat text.txt`  error :http/1.1 400 bad request connection: close

the following works fine:

curl -i -k -h "accept:application/*+xml;version=1.5" -h "x-vcloud-authorization: valid token" -x https://vcdurl/api

spent couple of days figure out stuck here.

token=" valid token" url="https://vcdurl" auth_header=x-vcloud-authorization:${token}  curl -i -k -x \   -h "accept:application/*+xml;version=1.5" \   -h "${auth_header}" \   "$url/api/vdc/7f252c90-eb3b-43c4-a5ef-458e5bf22c0e" \   | tee test.txt

note that:

  • a leading https:// has been added url variable's definition, bring parity working manually entered command.
  • we're quoting expansion of $url. (also, note change lower-case; see posix conventions environment variable names -- since shell variables share namespace environment variables, honoring these conventions avoids collisions environment variables having meaning system or shell).
  • we're no longer injecting literal quotes auth_header. (unlike syntactic quotes, parsed shell, literal quotes treated data, , passed through curl).
  • the (very buggy) echo $(cat test.txt) gone. (a sane way write cat test.txt, way; said, echo "$(cat test.txt)" remove worst of undesired behaviors; printf '%s\n' "$(<test.txt)" better, avoiding need either subshell or external utility [as cat not built shell itself, , has overhead invoke]).
