Pass array in curl Post call in Shell script-CodePudding

I am trying to do a curl call in my shell script where i want to pass the result of sql in data.

Please assume I have result stored in array as liveCalculators

curl_response=`curl -k -X POST "https://myapiurl" -H "accept: */*" -H "Content-Type: application/json" -d "{ \"keys\": [], \"calcs\": ${liveCalculators[@]}}" -w ";%{http_code}"`

I get Bad Request as error

Please suggest what can be done to fix it.

Like this :

(you need to deal how to populate calcs array before)

curl -k -X POST "https://myapiurl" \ 
    -H "accept: */*" \
    -H "Content-Type: application/json" \
    -w ";%{http_code}" \
    -d "@/dev/stdin" <<EOF
{ "keys": [], "calcs": [] }
EOF

Id liveCalculators is a shell array, not sure it works as-is. Tell us

CodePudding user response：

Your array output is not encapsulated as a valid JSON, so how about this:

curl_response=$(curl -k -X POST "https://myapiurl" -H "accept: */*" -H "Content-Type: application/json" -d "{ \"keys\": [], \"calcs\": \"${liveCalculators[@]}\" }" -w ";%{http_code}")

In addition, the output of the array liveCalculators is a BASH list, and you might need to do some parsing and search/replace, to convert it to a valid JSON list..
