GraphQL
GraphQL 既是一种用于 API 的查询语言也是一个满足你数据查询的运行时。 GraphQL 对你的 API 中的数据提供了一套易于理解的完整描述，使得客户端能够准确地获得它需要的数据，而且没有任何冗余，也让 API 更容易地随着时间推移而演进，还能用于构建强大的开发者工具。
Python
Query
Python
import graphene
class Query(graphene.ObjectType):
hello = graphene.String(name=graphene.String(default_value="World"))
def resolve_hello(self, info, name):
return 'Hello ' + name
schema = graphene.Schema(query=Query)
result = schema.execute('{ hello }')
print(result.data['hello']) # "Hello World"
Mutation
Python
import graphene
class CreatePerson(graphene.Mutation):
class Arguments:
name = graphene.String()
ok = graphene.Boolean()
person = graphene.Field(lambda: Person)
def mutate(root, info, name):
person = Person(name=name)
ok = True
return CreatePerson(person=person, ok=ok)
