#-*-coding:utf-8-*- #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 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) |

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！
