本文为大家分享了python+flask实现api的具体方法,供大家参考,具体内容如下
flask 框架
#-*-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 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)
python+flask创建api: 获取post请求传递的json数据
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:
from requests import post if __name__ == '__main__': path='"f:/nb_org_data/86574fg01/2013/1029/0008/86574fg01201310290008.img"' ret = post('http://localhost:50055/analyze/',json={'path':path}) print(ret.text)
将api封装为win32服务
import win32serviceutil import win32service import win32event import win32timezone from flask import flask,abort,jsonify,make_response,request import threading app = flask(__name__) _one_day_in_seconds = 60 * 60 * 24 @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'] def thread_target(): app.run(port='50055', debug=true) class grpcwin32client(win32serviceutil.serviceframework): _svc_name_ = 'grpcwin32client' _svc_display_name_ = 'nuctech grpc client' _svc_description_ = 'wiscan grpc client' def __init__(self, args): win32serviceutil.serviceframework.__init__(self, args) self.hwaitstop = win32event.createevent(none, 0, 0, none) #self.logger = self._getlogger() self.run = true def svcdorun(self): th = threading.thread(target=thread_target) th.start() try: while self.run: time.sleep(_one_day_in_seconds) except keyboardinterrupt: pass pass def svcstop(self): self.reportservicestatus(win32service.service_stop_pending) win32event.setevent(self.hwaitstop) self.run = false if __name__ == '__main__': import sys import servicemanager if len(sys.argv) == 1: try: evtsrc_dll = os.path.abspath(servicemanager.__file__) servicemanager.preparetohostsingle(grpcwin32client) servicemanager.initialize('grpcwin32client', evtsrc_dll) servicemanager.startservicectrldispatcher() except win32service.error as details: import winerror if details == winerror.error_failed_service_controller_connect: win32serviceutil.usage() else: win32serviceutil.handlecommandline(grpcwin32client)
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!
