Question

此宁静的客户端调用在“ test_rest.py”中定义的函数“ return_result”。

test_rest.py：

print("how may times this is called?")

def return_result(sentence):
    print(sentence)

我以这种方式提出了请求：

http://127.0.0.1:4000/sentence=hello

然后是我的rest.py

from flask import Flask, make_response
from flask_restful import Resource, Api

from test_rest import return_result

app = Flask(__name__)
api = Api(app)

class HelloWorld(Resource):
    def get(self, sentence):
        print("sentence:{}".format(sentence))
        c = return_result(sentence)
        print("result:{}".format(c))
        r = make_response(str(c))
        r.mimetype = 'application/json'
        return r

api.add_resource(HelloWorld, '/<string:sentence>')

if __name__ == '__main__':
    app.run(debug=True, host='127.0.0.1', port=5000)

控制台上的输出消息是：

 how may times this is called?
* Serving Flask app "rest" (lazy loading)
 * Environment: production
   WARNING: Do not use the development server in a production environment.
   Use a production WSGI server instead.
 * Debug mode: on
 * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
 * Restarting with stat
how may times this is called?
 * Debugger is active!
 * Debugger PIN: 289-783-459

如您所见，当我在浏览器中发出请求时，“调用了多少次”生成了两次？

这是为什么，以及如何纠正此宁静的服务功能？原因是当前的静态服务方式在我的程序中引起了问题。

为什么我的宁静客户两次调用库？
