Qt+python+爬虫

爬虫API腾讯疫情接口QT显示

自己一个做的一个小东西，很多部分不太完善，不喜勿喷！
如果大神有小建议和指点的话，欢迎欢迎欢迎!!!

原理介绍

1. 通过request请求，获得数据用Json解析数据，对数据提取，将这个写成一个py文件留出用于QT文件的接口。
2. 用pyqt_tool制作qt界面并生成py文件。
3. 将两个结合到一块，最后用pyinstaller打包生成exe文件

代码展示

1. accquiredata.py模块
用于抓取API接口，并对于数据处理的包

class accquire(object):
    d = {}
    f = {}
    date_list = []  # 日期
    confirm_list = []  # 确诊
    suspect_list = []  # 疑似
    dead_list = []  # 死亡
    heal_list = []  # 治愈

    def __init__(self):
        self.catch_distribution()
        # self.catch_daily()
    def catch_distribution(self):
        """抓取行政区域确诊分布数据"""

        url = 'https://view.inews.qq.com/g2/getOnsInfo?name=disease_h5&callback=&_=%d'%int(time.time()*1000)
        data = json.loads(requests.get(url=url).json()['data'])
        # print(data.keys())
        self.d = data['areaTree'][0]['children']
        self.f = [item['name'] for item in self.d]

    def catch_daily(self):
        """抓取每日确诊和死亡数据"""

        url = 'https://view.inews.qq.com/g2/getOnsInfo?name=wuwei_ww_cn_day_counts&callback=&_=%d'%int(time.time()*1000)
        data = json.loads(requests.get(url=url).json()['data'])
        data.sort(key=lambda x:x['date'])


        for item in data:
            month, day = item['date'].split('/')
            self.date_list.append(datetime.strptime('2020-%s-%s'%(month, day), '%Y-%m-%d'))
            self.confirm_list.append(int(item['confirm']))
            self.suspect_list.append(int(item['suspect']))
            self.dead_list.append(int(item['dead']))
            self.heal_list.append(int(item['heal']))
    def Find_Data(self,name):
        na = name.split(',')
        c = self.f.index(na[0])
        data = {}
        data[na[0]] = self.d[c]['total']['confirm']
        for item in self.d[c]['children']:
            if item['name'] not in data:
                data[item['name']]={'today':item['today'],'total':item['total']}
#                data.update({item['name']:item['total']['confirm']})
        return data[na[0]],data[na[1]]['total']['confirm'],data[na[1]]['total']['suspect']
    def plot_daily(self):
        """绘制每日确诊和死亡数据"""

        self.catch_daily() # 获取数据

2. PyQT_Form.py模块
用于创建qt界面

class Ui_Form(object):
    def setupUi(self, Form):
        Form.setObjectName("Form")
        Form.resize(1083, 784)
        palette = QtGui.QPalette()
        brush = QtGui.QBrush(QtGui.QColor(85, 0, 255))
        brush.setStyle(QtCore.Qt.SolidPattern)
        palette.setBrush(QtGui.QPalette.Active, QtGui.QPalette.Button, brush)
        brush = QtGui.QBrush(QtGui.QColor(85, 0, 255))
        brush.setStyle(QtCore.Qt.SolidPattern)
        palette.setBrush(QtGui.QPalette.Inactive, QtGui.QPalette.Button, brush)
        brush = QtGui.QBrush(QtGui.QColor(85, 0, 255))
        brush.setStyle(QtCore.Qt.SolidPattern)
        palette.setBrush(QtGui.QPalette.Disabled, QtGui.QPalette.Button, brush)
        Form.setPalette(palette)
        self.pushButton = QtWidgets.QPushButton(Form)
        self.pushButton.setGeometry(QtCore.QRect(230, 100, 91, 31))
        self.pushButton.setObjectName("pushButton")
        self.city = QtWidgets.QLineEdit(Form)
        self.city.setEnabled(True)
        self.city.setGeometry(QtCore.QRect(160, 150, 211, 31))
        self.city.setText("")
        self.city.setClearButtonEnabled(False)
        self.city.setObjectName("city")
        self.lineEdit_2 = QtWidgets.QLineEdit(Form)
        self.lineEdit_2.setGeometry(QtCore.QRect(510, 150, 331, 51))
        self.lineEdit_2.setPlaceholderText("")
        self.lineEdit_2.setObjectName("lineEdit_2")
        self.lineEdit_1 = QtWidgets.QLineEdit(Form)
        self.lineEdit_1.setGeometry(QtCore.QRect(510, 70, 331, 51))
        self.lineEdit_1.setPlaceholderText("")
        self.lineEdit_1.setObjectName("lineEdit_1")
        self.lineEdit_4 = QtWidgets.QLineEdit(Form)
        self.lineEdit_4.setGeometry(QtCore.QRect(510, 230, 331, 51))
        self.lineEdit_4.setPlaceholderText("")
        self.lineEdit_4.setObjectName("lineEdit_4")
        self.pushButton_2 = QtWidgets.QPushButton(Form)
        self.pushButton_2.setGeometry(QtCore.QRect(200, 300, 93, 28))
        self.pushButton_2.setObjectName("pushButton_2")
        self.gridLayoutWidget = QtWidgets.QWidget(Form)
        self.gridLayoutWidget.setGeometry(QtCore.QRect(150, 340, 701, 351))
        self.gridLayoutWidget.setObjectName("gridLayoutWidget")
        self.gridLayout = QtWidgets.QGridLayout(self.gridLayoutWidget)
        self.gridLayout.setContentsMargins(0, 0, 0, 0)
        self.gridLayout.setObjectName("gridLayout")

        self.retranslateUi(Form)
        self.pushButton.clicked.connect(Form.pushButton_click)
        self.pushButton_2.clicked.connect(Form.plot_click)
        QtCore.QMetaObject.connectSlotsByName(Form)

    def retranslateUi(self, Form):
        _translate = QtCore.QCoreApplication.translate
        Form.setWindowTitle(_translate("Form", "Form"))
        self.pushButton.setText(_translate("Form", "确定"))
        self.city.setPlaceholderText(_translate("Form", "请输入城市（如 陕西,西安）"))
        self.lineEdit_2.setText(_translate("Form", "省总数目:   "))
        self.lineEdit_1.setText(_translate("Form", "确诊数目:   "))
        self.lineEdit_4.setText(_translate("Form", "疑似病例:   "))
        self.pushButton_2.setText(_translate("Form", "走势"))

3. main.py
最后是主程序啦，用于把上述两个程序结合到一块就是主程序啦

class MyPyQT_Form(QtWidgets.QWidget,Ui_Form,accquire):
    def __init__(self):
        super(MyPyQT_Form,self).__init__()
        self.setupUi(self)
        # pg.setConfigOption('background', 'w')
        self.pw = pg.PlotWidget(title = "病毒人数曲线")
        self.pw.enableMouse()
        self.pw.setLabel(axis = "left", text = "/people")
        self.pw.setLabel(axis = "bottom",text = "time")
        self.pw.addLegend()
        # self.pw.setLable(axis="left", text="/people")
        self.gridLayout.addWidget(self.pw)
        # self.catch_daily()
        self.catch_distribution()
    def pushButton_click(self):
        self.a = self.city.text()
        b,q,f= self.Find_Data(self.a)
        q = "确诊数目:  "+str(q)
        b = "省总数目:  "+str(b)
        f = "疑似病例:  "+str(f)
        self.lineEdit_1.setText(q)
        self.lineEdit_2.setText(b)
        self.lineEdit_4.setText(f)
        return
    def plot_click(self):
        self.plot()
        return
    def plot(self):
         self.plot_daily()

         self.pw.plot(self.confirm_list,pen=(255,0,0), name="identify")
         self.pw.plot(self.suspect_list, pen=(0,255,0), name="suspect")
         self.pw.plot(self.dead_list, pen=(0,25,255), name="dead")
         self.pw.plot(self.heal_list, pen=(175,0,255), name="deal")
    def paintEvent(self, event):# set background_img
        painter = QPainter(self)
        painter.drawRect(self.rect())
        pixmap = QPixmap("./img/encourage.jpg")
        painter.drawPixmap(self.rect(), pixmap)

if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
    my_pyqt_form = MyPyQT_Form()
    my_pyqt_form.paintEngine()
    my_pyqt_form.show()
    sys.exit(app.exec_())

界面展示

功能说明
1.可以查询全国的地区的情况
tip:输入“，”的时候需要以英文的形式，如：陕西,西安
2.可以看清楚从病毒传染开始到现在的走势
