To upload an image in GraphQL in Flask, you can follow these steps:
- Install the required packages: Make sure you have Flask and Flask-GraphQL installed. If not, you can install them using pip:
1 2 |
pip install Flask pip install Flask-GraphQL |
- Set up a Flask app with GraphQL: Create a Flask app and set up a GraphQL schema using something like Graphene or Flask-GraphQL. Here's an example of setting up a Flask app with Graphene:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 |
from flask import Flask
from graphene import Schema, ObjectType, Field, String
app = Flask(__name__)
class Query(ObjectType):
hello = String(name=String(default_value="stranger"))
def resolve_hello(self, info, name):
return f"Hello, {name}!"
schema = Schema(query=Query)
@app.route("/graphql", methods=["POST"])
def graphql():
data = request.json
query = data["query"]
result = schema.execute(query)
return result.to_dict()
if __name__ == "__main__":
app.run()
|
- Upload image using GraphQL mutation: You can define a GraphQL mutation that accepts an image as input and saves it to a file or database. Here's an example of how you can define a mutation to upload an image in Graphene:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 |
from graphene import Mutation, InputObjectType, Field, String
class FileUploadInput(InputObjectType):
file = String()
class UploadFile(Mutation):
class Arguments:
file = FileUploadInput(required=True)
ok = Boolean()
def mutate(root, info, file):
# save the file to disk or database
return UploadFile(ok=True)
class Mutation(ObjectType):
upload_file = UploadFile.Field()
schema = Schema(query=Query, mutation=Mutation)
|
- Test the file upload mutation: You can test the file upload mutation by sending a GraphQL query with the file input. Here's an example of how you can test the mutation using a GraphQL client like Postman:
1 2 3 |
{
"query": "mutation { uploadFile(file: { file: 'path/to/image.jpg' }) { ok } }"
}
|
By following these steps, you should be able to upload an image in GraphQL in Flask.
