如何使用sanic API返回浮点数（或整数）？

Question

I am creating a simple Sanic REST API but cannot figure out how return numeric data. After looking at the docs , it appears that you can only return json , html , text , etc., but no float or int .

I am following the basic example in the docs, except have switched the return to a float:

from sanic import Sanic
from sanic.response import json

app = Sanic()

@app.route("/")
async def test(request):
    return 1.1

if __name__ == "__main__":
    app.run(host="0.0.0.0", port=8000)

However, it works perfectly if the return statement is return json({"hello": "world"}) . Why can I not return a float? I can return it as return text(1.1) , but then does the client who calls it receive it as a str (as opposed to a float )?

Answer 1

Just JSON your number.

>>> import json
>>> s = json.dumps(543.34)
>>> s
'543.34'
>>> json.loads(s)
543.34

With Sanic:

from sanic import Sanic, response
from sanic.response import json

app = Sanic()

@app.route("/")
async def test(request):
    return response.json(1.1)

if __name__ == "__main__":
    app.run(host="0.0.0.0", port=8000)
