此代码在我的本地计算机上运行良好，
flask.app的代码段
from flask import Flask
from flask_cors import CORS
app = Flask(__name__)
CORS(app, resources={r"/*": {"origins": "*"}})
@app.route("/", methods=['POST','GET'])
def hello():
return "Hello World!"
if __name__ == "__main__":
app.run(host="0.0.0.0", port=1025,debug = True)
