```aiohttp-apispec``` key features:
- ```docs``` and ```request_schema``` decorators
to add swagger spec support out of the box;
- ```validation_middleware``` middleware to enable validating
with marshmallow schemas from those decorators;
- **SwaggerUI** support.
- *New from version 2.0* - ```match_info_schema```, ```querystring_schema```,
```form_schema```, ```json_schema```, ```headers_schema``` and ```cookies_schema```
decorators for specific request parts validation.
Look [here](#more-decorators) for more info.
```aiohttp-apispec``` api is fully inspired by ```flask-apispec``` library
**Version 3.0.1 with apispec>=6.6.0 is available now** (`pip install aiohttp-apispec-acapy==3.0.1`).

## Install
```
pip install aiohttp-apispec
```
## Quickstart
*Also you can read [blog post](https://dmax.blog/how_to_easily_build_modern_web_apis_with_python_and_aiohttp) about quickstart with aiohttp-apispec*
```Python
from aiohttp_apispec import (
docs,
request_schema,
setup_aiohttp_apispec,
)
from aiohttp import web
from marshmallow import Schema, fields
class RequestSchema(Schema):
id = fields.Int()
name = fields.Str(description="name")
@docs(
tags=["mytag"],
summary="Test method summary",
description="Test method description",
)
@request_schema(RequestSchema(strict=True))
async def index(request):
return web.json_response({"msg": "done", "data": {}})
app = web.Application()
app.router.add_post("/v1/test", index)
# init docs with all parameters, usual for ApiSpec
setup_aiohttp_apispec(
app=app,
title="My Documentation",
version="v1",
url="/api/docs/swagger.json",
swagger_path="/api/docs",
)
# Now we can find spec on 'http://localhost:8080/api/docs/swagger.json'
# and docs on 'http://localhost:8080/api/docs'
web.run_app(app)
```
Class based views are also supported:
```python
class TheView(web.View):
@docs(
tags=["mytag"],
summary="View method summary",
description="View method description",
)
@request_schema(RequestSchema(strict=True))
@response_schema(ResponseSchema(), 200)
def delete(self):
return web.json_response(
{"msg": "done", "data": {"name": self.request["data"]["name"]}}
)
app.router.add_view("/v1/view", TheView)
```
As alternative you can add responses info to `docs` decorator, which is more compact way.
And it allows you not to use schemas for responses documentation:
```python
@docs(
tags=["mytag"],
summary="Test method summary",
description="Test method description",
responses={
200: {
"schema": ResponseSchema,
"description": "Success response",
}, # regular response
404: {"description": "Not found"}, # responses without schema
422: {"description": "Validation error"},
},
)
@request_schema(RequestSchema(strict=True))
async def index(request):
return web.json_response({"msg": "done", "data": {}})
```
## Adding validation middleware
```Python
from aiohttp_apispec import validation_middleware
...
app.middlewares.append(validation_middleware)
```
Now you can access all validated data in route from ```request['data']``` like so:
```Python
@docs(
tags=["mytag"],
summary="Test method summary",
description="Test method description",
)
@request_schema(RequestSchema(strict=True))
@response_schema(ResponseSchema, 200)
async def index(request):
uid = request["data"]["id"]
name = request["data"]["name"]
return web.json_response(
{"msg": "done", "data": {"info": f"name - {name}, id - {uid}"}}
)
```
You can change ``Request``'s ``'data'`` param to another with ``request_data_name`` argument of
``setup_aiohttp_apispec`` function:
```python
setup_aiohttp_apispec(
app=app,
request_data_name="validated_data",
)
...
@request_schema(RequestSchema(strict=True))
async def index(request):
uid = request["validated_data"]["id"]
...
```
Also you can do it for specific view using ```put_into```
parameter (beginning from version 2.0):
```python
@request_schema(RequestSchema(strict=True), put_into="validated_data")
async def index(request):
uid = request["validated_data"]["id"]
...
```
## More decorators
Starting from version 2.0 you can use shortenings for documenting and validating
specific request parts like cookies, headers etc using those decorators:
| Decorator name | Default put_into param |
|:----------|:-----------------|
| match_info_schema | match_info |
| querystring_schema | querystring |
| form_schema | form |
| json_schema | json |
| headers_schema | headers |
| cookies_schema | cookies |
And example:
```python
@docs(
tags=["users"],
summary="Create new user",
description="Add new user to our toy database",
responses={
200: {"description": "Ok. User created", "schema": OkResponse},
401: {"description": "Unauthorized"},
422: {"description": "Validation error"},
500: {"description": "Server error"},
},
)
@headers_schema(AuthHeaders) # <- schema for headers validation
@json_schema(UserMeta) # <- schema for json body validation
@querystring_schema(UserParams) # <- schema for querystring params validation
async def create_user(request: web.Request):
headers = request["headers"] # <- validated headers!
json_data = request["json"] # <- validated json!
query_params = request["querystring"] # <- validated querystring!
...
```
## Custom error handling
If you want to catch validation errors by yourself you
could use `error_callback` parameter and create your custom error handler. Note that
it can be one of coroutine or callable and it should
have interface exactly like in examples below:
```python
from marshmallow import ValidationError, Schema
from aiohttp import web
from typing import Optional, Mapping, NoReturn
def my_error_handler(
error: ValidationError,
req: web.Request,
schema: Schema,
error_status_code: Optional[int] = None,
error_headers: Optional[Mapping[str, str]] = None,
) -> NoReturn:
raise web.HTTPBadRequest(
body=json.dumps(error.messages),
headers=error_headers,
content_type="application/json",
)
setup_aiohttp_apispec(app, error_callback=my_error_handler)
```
Also you can create your own exceptions and create
regular Request in middleware like so:
```python
class MyException(Exception):
def __init__(self, message):
self.message = message
# It can be coroutine as well:
async def my_error_handler(
error, req, schema, error_status_code, error_headers
):
await req.app["db"].do_smth() # So you can use some async stuff
raise MyException({"errors": error.messages, "text": "Oops"})
# This middleware will handle your own exceptions:
@web.middleware
async def intercept_error(request, handler):
try:
return await handler(request)
except MyException as e:
return web.json_response(e.message, status=400)
setup_aiohttp_apispec(app, error_callback=my_error_handler)
# Do not forget to add your own middleware before validation_middleware
app.middlewares.extend([intercept_error, validation_middleware])
```
## Build swagger web client
#### 3.X SwaggerUI version
Just add `swagger_path` parameter to `setup_aiohttp_apispec` function.
For example:
```python
setup_aiohttp_apispec(app, swagger_path="/docs")
```
Then go to `/docs` and see awesome SwaggerUI
#### 2.X SwaggerUI version
If you prefer older version you can use
[aiohttp_swagger](https://github.com/cr0hn/aiohttp-swagger) library.
`aiohttp-apispec` adds `swagger_dict` parameter to aiohttp web application
after initialization (with `setup_aiohttp_apispec` function).
So you can use it easily like:
```Python
from aiohttp_apispec import setup_aiohttp_apispec
from aiohttp_swagger import setup_swagger
def create_app(app):
setup_aiohttp_apispec(app)
async def swagger(app):
setup_swagger(
app=app, swagger_url="/api/doc", swagger_info=app["swagger_dict"]
)
app.on_startup.append(swagger)
# now we can access swagger client on '/api/doc' url
...
return app
```
