#graphql #webdev #programming #tutorial

Make a GraphQL query request

curl 'https://countries.trevorblades.com/' \

-X POST \

-H 'content-type: application/json' \

--data '{

"query": "{ continents { code name } }"

}'

Make a mutation request

curl 'https://graphql-api-url' \

-X POST \

-H 'content-type: application/json' \

--data '{

"query":"mutation { createUser(name: \"John Doe\") }"

}'

Pass additional headers

If you need to pass authorization in a header, add another -H argument:

curl 'https://countries.trevorblades.com/' \
  -X POST \
  -H 'Authorization: Token xxxxx' \
  -H 'content-type: application/json' \
  --data '{
    "query": "{ continents { code name } }"
  }'

Printing response headers

If you want to see response headers, add -D - (dump headers to stdout):

curl 'https://countries.trevorblades.com/' \
  -X POST \
  -D - \
  -H 'content-type: application/json' \
  --data '{
    "query": "{ continents { code name } }"
  }'

Pretty printing response JSON

If you want to pretty print the output JSON, add | python -m json.tool in the end of the curl call.

curl 'https://countries.trevorblades.com/' \
  -X POST \
  -H 'content-type: application/json' \
  --data '{
    "query": "{ continents { code name } }"
  }' | python -m json.tool
