Examples

Let's see a Starlette example app:

"""OpenAPI2(Swagger) with Starlette
"""
from starlette.applications import Starlette
from starlette.requests import Request
from starlette.responses import JSONResponse
from starlette.endpoints import HTTPEndpoint
from uvicorn import run
from openapi_spec_validator import validate_v2_spec
from starlette.testclient import TestClient

from apiman.starlette import Extension


app = Starlette()
openapi = Extension(template="./examples/docs/cat_template.yml")
openapi.init_app(app)


# define data
CATS = {
    1: {"id": 1, "name": "DangDang", "age": 2},
    2: {"id": 2, "name": "DingDing", "age": 1},
}
# add schema definition
openapi.add_schema(
    "Cat",
    {
        "properties": {
            "id": {"description": "global unique", "type": "integer"},
            "name": {"type": "string"},
            "age": {"type": "integer"},
        },
        "type": "object",
    },
)


# define routes and schema(in doc string)
@app.route("/cat/")
class Cat(HTTPEndpoint):
    """

    def get(self, req: Request):
        return JSONResponse(CATS[int(req.path_params["id"])])

    def delete(self, req: Request):

        """
        cat = CATS.pop(int(req.path_params["id"]))
        return JSONResponse(cat)


# define doc by yaml or json file
@app.route("/cats/", methods=["GET"])
@openapi.from_file("./examples/docs/cats_get.yml")
def list_cats(req: Request):
    return JSONResponse(list(CATS.values()))


@app.route("/cats/", methods=["POST"])
@openapi.from_file("./examples/docs/cats_post.json")
async def list_cats(req: Request):
    cat = await req.json()
    CATS[cat["id"]] = cat
    return JSONResponse(cat)


if __name__ == "__main__":
    run(app)

Then we can get swagger web page at http://localhost:8000/apiman/swagger/: WebPage

See examples/ for more examples

How it works

  • Provide a base class("OpenApi") to handle api specification's collection
  • Provide extentions to extract api specification and register http endpoints to show UI web page and specification
