软件界面ui

ui设计

用的是PyQt5，先用Qt Designer设计界面，拖动组件改属性即可，注意objectName一定要改，保持良好的习惯。

主程序调用ui:

将ui文件转化成py文件Ui_weatherQuery.py，在这个文件里绑定事件，然后在主程序里面调用界面就可。

ui事件绑定业务函数：

在Ui_weatherQuery.py文件里，

self.queryBtn.clicked.connect(Dialog.queryWeather)
self.clearBtn.clicked.connect(Dialog.clearText)
self.pushButton.clicked.connect(Dialog.sendEmail)
主程序里与ui的交互
class MainDialog(QDialog):
    def __init__(self, parent=None):
        super(QDialog, self).__init__(parent)
        self.ui = Ui_weatherQuery.Ui_Dialog()
        self.ui.setupUi(self)

    def queryWeather(self):
        city_name = self.ui.txtCityName.text()
        self.res = query_weather(city_name=city_name)
        self.ui.txtQueryRes.setText(self.res)

    def clearText(self):
        self.ui.txtQueryRes.clear()
        self.ui.txtCityName.clear()

    def sendEmail(self):
        email_send.go(msg=self.res, subject_msg='天气预报')
        pass
显示界面模板框架
from PyQt5.QtWidgets import QApplication, QDial, QDialog

if __name__ == '__main__':
    myApp = QApplication(sys.argv)
    myDlg = MainDialog()
    myDlg.show()

    sys.exit(myApp.exec_())

调用api

api有免费的，申请就完事了。

用request包发送请求，返回的json解析一下就可。

def query_weather(city_name="武汉", record=True):
    appid = "29467327"
    appsecret = "27kJLhNF"
    # 请求地址&信息
    url = u"https://www.tianqiapi.com/free/week?appid={}&appsecret={}&city={}".format(
        appid, appsecret, city_name)
    # 发送请求得到返回结果
    r = requests.get(url)
    # 格式化显示json
    res = json.dumps(r.json(), indent=4, ensure_ascii=False)
    if record:
        with open("res.txt", 'w')as f:
            f.write(res)
    return res

邮件发送部分

# email负责邮件内容
