FastAPI: how to read body as any valid json?

由 ◇◆丶佛笑我妖孽 提交于 2021-02-18 14:00:47
问题 Sorry, not proficient in Python. I haven't found the docs for that use case. How can I get the request body, ensure its a valid Json ( any valid json , including numbers, string, booleans and nulls, not only objects and arrays) and get the actual Json. Using pydantic forces the Json to have a specific structure. 回答1: You can find nearly everything inside the Request object You are able to get request body with request.body() from fastapi import Request, FastAPI @app.post("/dummypath") async

How to add a custom decorator to a FastAPI route?

由 拈花ヽ惹草 提交于 2021-02-10 05:21:26
问题 I want to add an auth_required decorator to my endpoints. ( Please consider that this question is about decorators, not middleware ) So a simple decorator looks like this: def auth_required(func): def wrapper(*args, **kwargs): if user_ctx.get() is None: raise HTTPException(...) return func(*args, **kwargs) return wrapper So there are 2 usages: @auth_required @router.post(...) or @router.post(...) @auth_required The first way doesn't work because router.post creates a router that saved into

Python FastAPI Async Variable Sharing

由 爱⌒轻易说出口 提交于 2021-02-07 10:10:30
问题 If I had the below code, how would the variable service affect the asynchronous nature of the endpoints? Will the variable be shared? Or will it be locked when in use, thus blocking other endpoints from accessing it until the current one is done? I ask the above assuming that Service instances are stateless, i.e. it would be equivalent if I created an instance of Service in each endpoint. I am reluctant to do that because I don't know which is more time consuming, instantiating and destroying
