Flask Restful服务简单实现

　　官网：http://flask.pocoo.org/docs/1.0/quickstart/#routing

　　1、安装

　　　　windows下：pip3 install Flask

　　2、简单代码：

from flask import Flask,jsonify,make_response,request,make_response,abort
import weData
import os
# Flask初始化参数尽量使用你的包名，这个初始化方式是官方推荐的，官方解释：http://flask.pocoo.org/docs/0.12/api/#flask.Flask
app = Flask(__name__)

@app.route('/getBiz', methods=['GET','POST'])
def get_tasks():
    logPath = os.path.join(os.getcwd(), "log")
    obj = weData.weData(logPath)
    dict1 ={}
    # postman调用方式
    keyword = request.args.get('keyword')
    if not keyword:
        # 程序调用方式
        keyword = request.json['keyword']
    dict1['biz']=obj.catchBiz(keyword)
    print(dict1)
    return jsonify(dict1)

@app.errorhandler(404)
def not_found(error):
    return make_response(jsonify({'error': 'Not found'}), 404)

if __name__ == "__main__":
    app.run(host="0.0.0.0", port=8000,debug=False)

python调用方式

from urllib import request
import requests
import json
#
# import ssl
# ssl._create_default_https_context = ssl._create_unverified_context

class test:
    def __init__(self):
        pass

    def getBiz(self,keyword):
        data_json = {"keyword": keyword}
        headers = {'Content-type': 'application/json'}
        url = 'http://11.21.41.21:8000/getBiz'
        # post调用方式
        response = requests.post(url, json=data_json, headers=headers)
        # get调用方式
        # response = requests.get(url, json=data_json, headers=headers)
        dict1 = json.loads(response.text)
        biz = dict1.get("biz")
        print(keyword, ":", biz)



if __name__=="__main__":

    obj = test()
    obj.getBiz("支付宝")

from gevent.pywsgi import WSGIServer
from flask import Flask

app = Flask(__name__)
# CORS(app,  resources={r"/*": {"origins": "*"}})
PORT = 8087

@app.route('/index',methods=['GET'])
def index():
    return "Hello World!"

if __name__ == '__main__':
    #windows环境
    http_server = WSGIServer(('0.0.0.0', PORT), app)
    #linux环境
    http_server = WSGIServer(('', PORT), app)
    http_server.serve_forever()
