Read and write json files to server with flask

I need a json file on the server to store some data, but it won't be too big to need a database. So I try to read the file, and after I finish using it I will need to overwrite the data to keep update. I tried like this:

@app.route("/json")
def readwrite():
    SITE_ROOT = os.path.realpath(os.path.dirname(__file__))
    json_url = os.path.join(SITE_ROOT,'static', 'test.json')
    token = open(json_url)
    return token

But I get a 404 error on those. I'm not sure how I can read out those data and further rewrite. Please help if you see any problem in my code. Thanks!

You are returning the file handle via HTTP to the client. Get the json data and send that.

stored_json = token.readlines()
token.close()
return stored_json
