Error in using EXEC filter for curl

Hi All,

We have a scenario where through curl we are getting some output, when tried the curl command directly we are getting the output.

curl --location --request POST 'https://demo.cloud.ie/api/v2/analytics/conversations/aggregates/query'
 --header 'Authorization: Bearer Ejd22Vdsfergvvsdrgar' --header 'Cont
ent-Type: application/json'  --data '{  "interval": "2021-08-09T18:30:00.000Z/2021-08-10T18:30:00.000Z",  "metrics": [ "nOffered", "tAn
swered", "tAbandon" ] } '

And this is the output

{"results":[{"group":{"mediaType":"chat"},"data":[{"interval":"2021-08-09T18:30:00.000Z/2021-08-10T18:30:00.000Z","metrics":[{"metric":
"nOffered","stats":{"count":5}},{"metric":"tAnswered","stats":{"max":8500505,"min":2966,"count":5,"sum":17101288}}]}]},{"group":{"media
Type":"email"},"data":[{"interval":"2021-08-09T18:30:00.000Z/2021-08-10T18:30:00.000Z","metrics":[{"metric":"nOffered","stats":{"count"
:8}},{"metric":"tAnswered","stats":{"max":7619543,"min":6446,"count":8,"sum":11067681}}]}]},{"group":{"mediaType":"voice"},"data":[{"in
terval":"2021-08-09T18:30:00.000Z/2021-08-10T18:30:00.000Z","metrics":[{"metric":"nOffered","stats":{"count":30}},{"metric":"tAbandon",
"stats":{"max":143658,"min":1460,"count":15,"sum":457995}},{"metric":"tAnswered","stats":{"max":40646,"min":3107,"count":14,"sum":14216
0}}]}]}]}

When i try putting the same into logstash using exec filter i am getting error, here is my logstash input filter

input {
    exec {
command => " curl --location --request POST 'https://demo.cloud.ie/api/v2/analytics/conversations/aggregates/query'
 --header 'Authorization: Bearer Ejd22Vdsfergvvsdrgar' --header 'Cont
ent-Type: application/json'  --data '{  "interval": "2021-08-09T18:30:00.000Z/2021-08-10T18:30:00.000Z",  "metrics": [ "nOffered", "tAn
swered", "tAbandon" ] } ' "
schedule => "* * * * *"
}
}

While running this i am getting error like below

Any advice, where i'm going wrong?

Hi,

You have to escape all double quotes of the command.

Hi @Cad

We tried but our source system is not accepting the query without double quotes.

{"message":"The request could not be understood by the server due to malformed syntax.","code":"bad.request","status":400,"contextId":"

Any way where we can keep the double quotes and run the curl in logstash?

Thanks
Gautham

On this previous topic https://discuss.elastic.co/t/logstash-http-poller-body-escape-double-and-single-quotation-marks/282039/2?u=cad someone suggest to use unicode. It's on a different plugin but you should give a try. The unicode for quotes is \u0022

Cad.

@Cad Tried it, but no luck :frowning:

Thanks

According to this source the following code should work.

' curl --location --request POST "https://demo.cloud.ie/api/v2/analytics/conversations/aggregates/query" --header "Authorization: Bearer Ejd22Vdsfergvvsdrgar" --header "Content-Type: application/json"  --data "{ \"interval\": \"2021-08-09T18:30:00.000Z/2021-08-10T18:30:00.000Z\",  \"metrics\": [ \"nOffered\", \"tAnswered\", \"tAbandon\" ] } " '
