cannot add extra info from Query

[rainbow2019s]

WTForm can add helper info custom desc,but I can not find in Query,Path and Body

[Mause]

What extra info are you referring to?

[rainbow2019s]

@app.get('/api') #/api?limit=100
async def admin(
limit:int=Query(...,ge=1,le=10,description='参数错误')
):
return {'limit':limit}

@app.exception_handler(RequestValidationError)
async def validation_exception_handler(request, exc):
# print(type(exc.errors()))
return JSONResponse(
status_code=400,
content={
'code':'10001',
'message':exc.errors()[0]['msg'],
'data':{}}
)

I want to get description in exception_handler to replace default msg
