#pip install flask
#pip install flask-restful
from flask import flask
app = flask(__name__)
@app.route('/')
def index():
return "hello world!"
if __name__ == '__main__':
app.run(debug=true)

pycharm运行该程序后，在浏览器输入http://127.0.0.1:5000/，即可看到一个网页：
flask + flask_restful创建一个简单的应用程序:

from flask_restful import resource,api
app = flask(__name__)
api = api(app)
class helloworld(resource):
def get(self):
return {"hello":"world"}
api.add_resource(helloworld,'/')
if __name__ == '__main__':
app.run(debug=true)

from flask import flask,abort,jsonify,make_response,request
app = flask(__name__)
@app.route('/analyze/' ,methods=['post'])
def call_wiscan_analyze():
if not request.json or not 'path' in request.json:
abort(400)
path = request.json['path']
if __name__ == '__main__':
app.run(port='50055',debug=true)

请求：

ret = post('http://localhost:50055/analyze/',json={'path':path})
print(ret.text)

将api封装为win32服务

注意：
启动一个线程运行app.run()，否则安装完win32服务，启动服务后，无法停止服务，因为app内部循环没有结束！
