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)

from PyQt5 import QtCore, QtGui, QtWidgets
from Event import EventClass
class Ui_MainWindow(object):
 def setupUi(self, MainWindow):
 event=EventClass()
 MainWindow.setObjectName("MainWindow")
 MainWindow.resize(793, 604)
 MainWindow.setStyleSheet("font: 10pt \"Microsoft YaHei UI\";")
 self.centralwidget = QtWidgets.QWidget(MainWindow)
 self.centralwidget.setObjectName("centralwidget")
 self.widget = QtWidgets.QWidget(self.centralwidget)
 self.widget.setGeometry(QtCore.QRect(0, 0, 791, 43))
 self.widget.setObjectName("widget")
 self.horizontalLayout = QtWidgets.QHBoxLayout(self.widget)
 self.horizontalLayout.setSizeConstraint(QtWidgets.QLayout.SetNoConstraint)
 self.horizontalLayout.setContentsMargins(10, 1, 1, 3)
 self.horizontalLayout.setSpacing(15)
 self.horizontalLayout.setObjectName("horizontalLayout")
 self.label = QtWidgets.QLabel(self.widget)
 self.label.setObjectName("label")
 self.horizontalLayout.addWidget(self.label)
 self.lineEdit = QtWidgets.QLineEdit(self.widget)
 self.lineEdit.setMaximumSize(QtCore.QSize(742, 16777215))

 self.pushButton.setObjectName("pushButton")
 self.horizontalLayout.addWidget(self.pushButton)
 self.scrollArea = QtWidgets.QScrollArea(self.centralwidget)
 self.scrollArea.setGeometry(QtCore.QRect(0, 40, 791, 561))
 self.scrollArea.setWidgetResizable(True)
 self.scrollArea.setObjectName("scrollArea")
 self.scrollAreaWidgetContents = QtWidgets.QWidget()
 self.scrollAreaWidgetContents.setGeometry(QtCore.QRect(0, 0, 789, 559))
 self.scrollAreaWidgetContents.setObjectName("scrollAreaWidgetContents")
 self.tableWidget = QtWidgets.QTableWidget(self.scrollAreaWidgetContents)

 sizePolicy.setHorizontalStretch(0)

 sizePolicy.setHeightForWidth(self.tableWidget.sizePolicy().hasHeightForWidth())
 self.tableWidget.setSizePolicy(sizePolicy)
 self.tableWidget.setBaseSize(QtCore.QSize(0, 0))

 self.line.setToolTipDuration(0)
 self.line.setLineWidth(1)
 self.line.setFrameShape(QtWidgets.QFrame.HLine)
 self.line.setFrameShadow(QtWidgets.QFrame.Sunken)
 self.line.setObjectName("line")
 self.scrollArea.setWidget(self.scrollAreaWidgetContents)
 MainWindow.setCentralWidget(self.centralwidget)

 self.retranslateUi(MainWindow)
 self.pushButton.clicked.connect(lambda :event.search(self.tableWidget, self.lineEdit.text(), self.lineEdit_2.text(), self.dateEdit.date().toPyDate()))
 QtCore.QMetaObject.connectSlotsByName(MainWindow)

 def retranslateUi(self, MainWindow):
 _translate = QtCore.QCoreApplication.translate
 MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
 self.label.setText(_translate("MainWindow", "From"))
 self.label_2.setText(_translate("MainWindow", "To"))

 item = self.tableWidget.horizontalHeaderItem(0)
 item.setText(_translate("MainWindow", "车次"))

 item.setText(_translate("MainWindow", "硬卧"))
 item = self.tableWidget.horizontalHeaderItem(4)
 item.setText(_translate("MainWindow", "硬座"))


if __name__ == "__main__":
 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"
 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".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

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持。
