Question

我希望Google api这样显示我的业务：

import flask
import main_function as mf
from flask_cors import CORS,cross_origin

app = flask.Flask(__name__)
CORS(app)
app.config["DEBUG"] = True


@app.route('/api/v1.0/second_page/<ticker>/<doc_type>/<selection>',methods=['GET'])
def get_aggregated_past_data_for_selection(ticker,selection,doc_type):
    num_iter = 0
    new_ticker_flag = True

    if ticker and doc_type and selection:
        final_value_dict = mf.combine_past_data(ticker,doc_type,selection,num_iter,new_ticker_flag,calling_from='api')
        response = flask.jsonify(final_value_dict)
        response.headers.add('Access-Control-Allow-Origin', 'http://localhost:4200')
        return response

    else:
        return flask.jsonify({"Error": “Some fields missing. Please try againr."})

if __name__ == '__main__':
    app.run(host='0.0.0.0')

Access to XMLHttpRequest at 'http://192.168.1.14:5000/api/v1.0/second_page/AAPL/10-K/24_2_5' from origin 'http://localhost:4200' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

为什么Google API不显示我在Google上设置的业务？
