PyQt5+requests实现车票查询工具
作者:__师寇__ 时间:2023-11-01 02:12:25
PyQt5+requests实现一个车票查询工具,供大家参考,具体内容如下
结构图
效果图
思路
1、search(QPushButton)点击信号(clicked)连接到自定义的槽函数(event.search)
2、槽函数(event.search)接收四个参数:QTableWidget对象的引用、两个QLabel中的内容(站台名称)、QDateEdit格式化日期
3、槽函数(event.search)调用爬虫类(TrainService)获取车次信息,添加到QTableWidget对象中。
代码
1、ui.py(ui界面)
# -*- coding: utf-8 -*-
# Form implementation generated from reading ui file 'E:\Python\Qt\ui_0.ui'
#
# Created by: PyQt5 UI code generator 5.11.2
#
# WARNING! All changes made in this file will be lost!
from PyQt5 import QtCore, QtGui, QtWidgets

self.horizontalLayout.setContentsMargins(10, 1, 1, 3)

self.label = QtWidgets.QLabel(self.widget)

self.scrollArea = QtWidgets.QScrollArea(self.centralwidget)
self.scrollArea.setGeometry(QtCore.QRect(0, 40, 791, 561))
self.scrollArea.setWidgetResizable(True)
self.scrollArea.setObjectName("scrollArea")

import sys
app = QtWidgets.QApplication(sys.argv)
MainWindow = QtWidgets.QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(MainWindow)
MainWindow.show()
sys.exit(app.exec_())
2、EventClass.py(自定义槽函数类)
#coding:u8
import time
from PyQt5.QtWidgets import QTableWidgetItem
from TrainService import TrainService
class EventClass(object):
def __init__(self):
self.trainService=TrainService()
pass
def search(self, table, From="北京", To="上海", Date=time.strftime("%Y-%m-%d", time.localtime())):
print("【{}】 form {} to {}".format(Date, From, To))
train_list=self.trainService.crawlTrainMess(From, To, Date)
print(table)
table.setRowCount(len(train_list))
for row, item in enumerate(train_list):
for col, i in enumerate(item):
if i is "":
i="0"
table.setItem(row, col, QTableWidgetItem(i))
pass
3、TrainService.py(爬虫类)
#coding_url:u8
import requests
import json
class TrainService(object):
def __init__(self):
with open("code.json", 'r') as file:
code=eval(file.read())
self.code=code
self.code_url="https://kyfw.12306.cn/otn/resources/js/framework/station_name.js?station_version=1.9002"
self.headers={"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.7 Safari/537.36"}
def crawlTrainMess(self,from_station,to_station,train_date):
self.url="https://kyfw.12306.cn/otn/leftTicket/queryZ?leftTicketDTO.train_date={}&leftTicketDTO.from_station={}&leftTicketDTO.to_station={}&purpose_codes=ADULT".format(train_date,self.code[from_station],self.code[to_station])
response=requests.get(self.url,headers=self.headers)
train_json=json.loads(response.text)
results=train_json['data']['result']
train_list=[]
for i in results:
temp=i.split('|')
train_list.append([temp[3], temp[8], temp[9], temp[25], temp[26]])
#print(train_list)
return train_list
def crawlCodeMess(self):
response=requests.get(self.code_url,headers=self.headers)
station_list=response.text.split('@')[1 :]
code={}
for i in station_list:
temp=i.split('|')
code[temp[1]]=temp[2]
#print(code)
with open("code.json", 'w') as file:
file.write(str(code))
if __name__=="__main__":
ts=TrainService()
ts.crawlCodeMess()
需要先跑 TrainService.py 获取到站点对应的代码信息code.json
然后在执行 ui.py
