README
Generate REST API and OpenAPI documentation for your Flask project.
**Flask OpenAPI3** is a web API framework based on **Flask**. It uses **Pydantic** to verify data and automatic
generation of interaction documentation.
The key features are:
- **Easy to code:** Easy to use and easy to learn
- **Standard document specification:** Based on [OpenAPI Specification](https://spec.openapis.org/oas/v3.1.0)
- **Interactive OpenAPI documentation:** [Swagger](https://github.com/swagger-api/swagger-ui), [Redoc](https://github.com/Redocly/redoc), [RapiDoc](https://github.com/rapi-doc/RapiDoc), [RapiPdf](https://mrin9.github.io/RapiPdf/), [Scalar](https://github.com/scalar/scalar), [Elements](https://github.com/stoplightio/elements)
- **Data validation:** Fast data verification based on [Pydantic](https://github.com/pydantic/pydantic)
## Requirements
Python 3.8+
flask-openapi3 is dependent on the following libraries:
- [Flask](https://github.com/pallets/flask) for the web app.
- [Pydantic](https://github.com/pydantic/pydantic) for the data validation.
## Installation
```bash
pip install -U flask-openapi3[swagger]
```
or
```bash
conda install -c conda-forge flask-openapi3[swagger]
```
Optional dependencies
- [python-email-validator](https://github.com/JoshData/python-email-validator) supports email verification.
- [python-dotenv](https://github.com/theskumar/python-dotenv#readme) enables support
for [Environment Variables From dotenv](https://flask.palletsprojects.com/en/latest/cli/#dotenv) when running `flask`
commands.
- [pyyaml](https://github.com/yaml/pyyaml) is used to output the OpenAPI document in yaml format.
- [asgiref](https://github.com/django/asgiref) allows views to be defined with `async def` and use `await`.
- [flask-openapi3-plugins](https://github.com/luolingchun/flask-openapi3-plugins) Provide OpenAPI UI for flask-openapi3.
To install these dependencies with flask-openapi3:
```bash
pip install flask-openapi3[yaml]
# or
pip install flask-openapi3[async]
# or
pip install flask-openapi3[dotenv]
# or
pip install flask-openapi3[email]
# or all
pip install flask-openapi3[yaml,async,dotenv,email]
# or manually
pip install pyyaml asgiref python-dotenv email-validator
# OpenAPI UI plugins
pip install -U flask-openapi3[swagger,redoc,rapidoc,rapipdf,scalar,elements]
```
## A Simple Example
Here's a simple example, further go to the [Example](https://luolingchun.github.io/flask-openapi3/latest/Example/).
```python
from pydantic import BaseModel
from flask_openapi3 import Info, Tag
from flask_openapi3 import OpenAPI
info = Info(title="book API", version="1.0.0")
app = OpenAPI(__name__, info=info)
book_tag = Tag(name="book", description="Some Book")
class BookQuery(BaseModel):
age: int
author: str
@app.get("/book", summary="get books", tags=[book_tag])
def get_book(query: BookQuery):
"""
to get all books
"""
return {
"code": 0,
"message": "ok",
"data": [
{"bid": 1, "age": query.age, "author": query.author},
{"bid": 2, "age": query.age, "author": query.author}
]
}
if __name__ == "__main__":
app.run(debug=True)
```
Class-based API View Example
```python
from typing import Optional
from pydantic import BaseModel, Field
from flask_openapi3 import OpenAPI, Tag, Info, APIView
info = Info(title='book API', version='1.0.0')
app = OpenAPI(__name__, info=info)
api_view = APIView(url_prefix="/api/v1", view_tags=[Tag(name="book")])
class BookPath(BaseModel):
id: int = Field(..., description="book ID")
class BookQuery(BaseModel):
age: Optional[int] = Field(None, description='Age')
class BookBody(BaseModel):
age: Optional[int] = Field(..., ge=2, le=4, description='Age')
author: str = Field(None, min_length=2, max_length=4, description='Author')
@api_view.route("/book")
class BookListAPIView:
a = 1
@api_view.doc(summary="get book list")
def get(self, query: BookQuery):
print(self.a)
return query.model_dump_json()
@api_view.doc(summary="create book")
def post(self, body: BookBody):
"""description for a created book"""
return body.model_dump_json()
@api_view.route("/book/")
class BookAPIView:
@api_view.doc(summary="get book")
def get(self, path: BookPath):
print(path)
return "get"
@api_view.doc(summary="update book")
def put(self, path: BookPath):
print(path)
return "put"
@api_view.doc(summary="delete book", deprecated=True)
def delete(self, path: BookPath):
print(path)
return "delete"
app.register_api_view(api_view)
if __name__ == "__main__":
app.run(debug=True)
```
