CURL error "URL using bad/illegal format or missing URL" when trying to pass variable as a part of URL

Question

When I'm trying to execute script below and getting error: "curl: (3) URL using bad/illegal format or missing URL"

#!/bin/bash

stage="develop"
branch="branch_name"

getDefinition=$(curl -u [email protected]:password -X GET "https://dev.azure.com/organization/project/_apis/build/definitions?api-version=5.1")

for def in $(echo "$getDefinition" | jq '.value[] | select (.path=="\\Some_path\\'$stage'") | .id'); do
  getBuildInfo=$(curl -u [email protected]:password -X GET "https://dev.azure.com/organization/project/_apis/build/definitions/${def}\?api-version=5.1")
        # echo $def
        body=$(echo "${getBuildInfo}" | jq '.repository.defaultBranch = "refs/heads/release/'"${branch}"'"' | jq '.options[].inputs.branchFilters = "[\"+refs/heads/release/'"${branch}"'\"]"' | jq '.triggers[].branchFilters[] = "+refs/heads/release/'"${branch}"'"')
        echo ${body} > data.json    
done

It happens when I'm trying to pass variable ${def} into a line:

curl -u [email protected]:password -X GET "https://dev.azure.com/organization/project/_apis/build/definitions/${def}\?api-version=5.1"

But when I declare an array, curl works as expected. Example:

declare -a def
def=(1 2 3 4)

curl -u [email protected]:password -X GET "https://dev.azure.com/organization/project/_apis/build/definitions/${def}\?api-version=5.1"

Could you please suggest how can I pass variable into URL properly?

Answer 1

Do you need to call curl for 4 times? If so.

for def in 1 2 3 4; do curl -u [email protected]:password -X GET "https://dev.azure.com/organization/project/_apis/build/definitions/${def}\?api-version=5.1"; done
