使用烧瓶服务器获得 Covid 疫苗

在本文中，我们将使用 Flask Server 构建 Covid 疫苗可用性检查器。

我们都知道，整个世界都在遭受疫情病毒的折磨，唯一能帮助我们摆脱这种局面的就是大规模疫苗接种。但正如我们所知，由于该国人口众多，在我们附近地区很难找到疫苗。因此，现在技术进入了我们的视野，我们将建立自己的 covid 疫苗可用性检查器，它可以发现我们附近地区的疫苗可用性。

我们将使用一些 python 库来查找疫苗的可用性，并使用烧瓶服务器显示它们。将来，您也可以将其部署在实时服务器上。首先，我们必须使用下面的命令安装 python Flask 包:

pip install flask

安装 python 烧瓶包后，打开 Pycharm 或任何 IDE(最好是 Visual Studio 代码)并创建一个新项目。之后制作一个主 python 文件 app.py 和两个名为模板的文件夹，另一个是静态(文件夹名称必须和写的一样)。

下面是代表项目目录结构的图片。

分步实施

步骤 1: 在第一步中，我们必须导入 python 库，我们将在项目中进一步使用这些库。另外，制作一个 Flask 服务器的应用程序。

计算机编程语言

from flask import Flask,request,session,render_template
import requests,time
from datetime import datetime,timedeltaapp = Flask(__name__)

步骤 2: 添加路由来处理客户端请求。

@app.route('/')
def home():# rendering the homepage of projectreturn render_template("index.html")@app.route('/CheckSlot')
def check():# for checking the slot available or not# fetching pin codes from flaskpin = request.args.get("pincode")# fetching age from flaskage = request.args.get("age")data = list()# finding the slotresult = findSlot(age, pin, data)if(result == 0):return render_template("noavailable.html")return render_template("slot.html", data=data)

**第三步:**这是我们项目的主要步骤，找到疫苗的可用性(findslot()函数，将做以下事情):

首先从 python 的 DateTime 库中获取年龄、pin 和查找日期等参数。
从 cowin 官方网站上删除数据，如疫苗剂量、疫苗接种中心、可用性、疫苗类型和价格等。
将所有数据存储在 python 列表中。

def findSlot(age,pin,data):flag = 'y'num_days =  2actual = datetime.today()list_format = [actual + timedelta(days=i) for i in range(num_days)]actual_dates = [i.strftime("%d-%m-%Y") for i in list_format]while True:counter = 0for given_date in actual_dates:# cowin website Api for fetching the dataURL = "https://cdn-api.co-vin.in/api/v2/appointment/sessions/public/calendarByPin?pincode={}&date={}".format(pin, given_date)header = {'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.76 Safari/537.36'}# Get the results in json format.result = requests.get(URL,headers = header)if(result.ok):response_json = result.json()if(response_json["centers"]):# Checking if centres available or notif(flag.lower() == 'y'):for center in response_json["centers"]:# For Storing all the centre and all parametersfor session in center["sessions"]:# Fetching the availability in particular sessiondatas = list()# Adding the pincode of area in listdatas.append(pin)# Adding the dates available in listdatas.append(given_date)# Adding the centre name in listdatas.append(center["name"])# Adding the block name in listdatas.append(center["block_name"])# Adding the vaccine cost type whether it is# free or chargable.datas.append(center["fee_type"])# Adding the available capacity or amount of # doses in listdatas.append(session["available_capacity"])if(session["vaccine"]!=''):datas.append(session["vaccine"])counter =counter + 1# Add the data of particular centre in data list.if(session["available_capacity"]>0):data.append(datas)else:print("No response")if counter == 0:return 0return 1

下面是 app.py 的完整实现

from flask import Flask,request,session,render_template
import requests,time
from datetime import datetime,timedeltaapp = Flask(__name__)@app.route('/')
def home():return render_template("index.html")@app.route('/CheckSlot')
def check():# fetching pin codes from flaskpin = request.args.get("pincode")# fetching age from flaskage = request.args.get("age")data = list()# finding the slotresult = findSlot(age,pin,data)if(result == 0):return render_template("noavailable.html") return render_template("slot.html",data = data)def findSlot(age,pin,data):flag = 'y'num_days =  2actual = datetime.today()list_format = [actual + timedelta(days=i) for i in range(num_days)]actual_dates = [i.strftime("%d-%m-%Y") for i in list_format]# print(actual_dates)while True:counter = 0for given_date in actual_dates:# cowin website Api for fetching the dataURL = "https://cdn-api.co-vin.in/api/v2/appointment/sessions/public/calendarByPin?pincode={}&date={}".format(pin, given_date)header = {'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.76 Safari/537.36'}# Get the results in json format.result = requests.get(URL,headers = header)if(result.ok):response_json = result.json()if(response_json["centers"]):# Checking if centres available or notif(flag.lower() == 'y'):for center in response_json["centers"]:# For Storing all the centre and all parametersfor session in center["sessions"]:# Fetching the availability in particular sessiondatas = list()# Adding the pincode of area in listdatas.append(pin)# Adding the dates available in listdatas.append(given_date)# Adding the centre name in listdatas.append(center["name"])# Adding the block name in listdatas.append(center["block_name"])# Adding the vaccine cost type whether it is# free or chargable.datas.append(center["fee_type"])# Adding the available capacity or amount of # doses in listdatas.append(session["available_capacity"])if(session["vaccine"]!=''):datas.append(session["vaccine"])counter =counter + 1# Add the data of particular centre in data list.if(session["available_capacity"]>0):data.append(datas)else:print("No response")if counter == 0:return 0return 1if __name__ == "__main__":app.run()

步骤 4: 现在在模板文件夹中制作三个文件。

index.html: 显示项目主页，用于输入年龄和 pin 码。
slot.html: 在页面上显示数据。
不可用. html: 如果疫苗在任何中心都找不到，那么-没有可用页面。

index.html 码
