This is a GraphQL client for Python.
Plays nicely with graphene, graphql-core, graphql-js and any other GraphQL implementation compatible with the spec.
GQL architecture is inspired by React-Relay and Apollo-Client.
$ pip install gql
The example below shows how you can execute queries against a local schema.
from gql import gql, Client
from .someSchema import SampleSchema
client = Client(schema=SampleSchema)
query = gql('''
{
hello
}
''')
client.execute(query)If you want to add additional headers when executing the query, you can specify these in a transport object:
from gql import Client
from gql.transport.requests import RequestsHTTPTransport
from .someSchema import SampleSchema
client = Client(transport=RequestsHTTPTransport(
url='/graphql', headers={'Authorization': 'token'}), schema=SampleSchema)To execute against a graphQL API. (We get the schema by using introspection).
from gql import gql, Client
from gql.transport.requests import RequestsHTTPTransport
sample_transport=RequestsHTTPTransport(
url='https://countries.trevorblades.com/',
use_json=True,
headers={
"Content-type": "application/json",
},
verify=False
)
client = Client(
retries=3,
transport=sample_transport,
fetch_schema_from_transport=True,
)
query = gql('''
query getContinents {
continents {
code
name
}
}
''')
client.execute(query)If you have a local schema stored as a schema.graphql file, you can do:
from graphql import build_ast_schema, parse
from gql import gql, Client
with open('path/to/schema.graphql') as source:
document = parse(source.read())
schema = build_ast_schema(document)
client = Client(schema=schema)
query = gql('''
{
hello
}
''')
client.execute(query)See CONTRIBUTING.md
