python+flask实现API的方法
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！
