Pyqt5+designer+python 实现个性签名小软件

最终效果图如上所示

第一步

先在designer画好软件效果布局

保存为qianming2.ui 然后在vscode里转成Ui_qianming2.py文件

        self.textEdit.setObjectName("textEdit")
        self.pushButton = QtWidgets.QPushButton(self.centralwidget)
        self.pushButton.setGeometry(QtCore.QRect(30, 100, 141, 51))
        self.pushButton.setObjectName("pushButton")
        self.label = QtWidgets.QLabel(self.centralwidget)
        self.label.setGeometry(QtCore.QRect(30, 190, 661, 201))
        self.label.setText("")

        self.comboBox.setGeometry(QtCore.QRect(450, 30, 141, 51))
        self.comboBox.setLayoutDirection(QtCore.Qt.LeftToRight)

        MainWindow.setStatusBar(self.statusbar)

        self.retranslateUi(MainWindow)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)

    def retranslateUi(self, MainWindow):
        _translate = QtCore.QCoreApplication.translate

        self.comboBox.setItemText(5, _translate("MainWindow", "商务签"))
        self.comboBox.setItemText(6, _translate("MainWindow", "可爱签"))

第二步

编写代码：

import sys
from PyQt5.QtWidgets import QApplication, QMainWindow,QMessageBox  
from PyQt5.QtGui import *
from PyQt5 import QtWidgets 
import Ui_qianming2
from functools import partial
import requests
from bs4 import BeautifulSoup

#这里是消息提示弹出框的主要代码
class MyWindow(QtWidgets.QWidget):  
    def __init__(self):  
        super().__init__()  
    #消息提示框
    def msg(self):  
        QMessageBox.warning(self,"提示框","输入框不能留空")
        # QMessageBox.question(self,"消息框标题","这是一条问答。")
        # QMessageBox.information(self,"消息框标题","这是一条消息。")



#主要处理函数
def convert(ui):
    text = ui.comboBox.currentText()#返回选中项的文本内容
    if text == '个性签':
        font = 'jfcs.ttf'
    elif text == '连笔签':
        font = 'qmt.ttf'
    elif text == '潇洒签':
        font = 'bzcs.ttf'
    elif text == '草体签':
        font = 'lfc.ttf'        
    elif text == '合文签':
        font = 'haku.ttf'
    elif text == '商务签':
        font = 'zql.ttf'
    else:
        font = 'yqk.ttf'


    start_url = 'http://www.uustv.com/'
    name = ui.textEdit.toPlainText()
    if name == '':
        myw = MyWindow()
        myw.msg()
        return
    else:
        name = ui.textEdit.toPlainText()
    data = {
        'word': name,
        'sizes': '60',
        'fonts': font,
        'fontcolor': '#000000'
    }
    result = requests.post(start_url, data=data)
    result.encoding='utf-8'
    html = result.text
    soup = BeautifulSoup(html,'html.parser') 
    img_url = soup.find('div', class_="tu").find('img')['src']
    Urls = start_url + img_url
    res = requests.get(Urls)
    #引用网络图片地址
    img = QImage.fromData(res.content)
    ui.label.setPixmap(QPixmap.fromImage(img))
    '''
    #已用本地图片地址代码
    pic=res.content
    with open('{}'.format(img_url.split('/')[-1]), 'wb') as f:
        f.write(pic)
    ui.label.setPixmap(QPixmap(img_url.split('/')[-1]))
    '''


if __name__ == '__main__':
    app = QApplication(sys.argv)
    MainWindow = QMainWindow()
    ui = Ui_qianming2.Ui_MainWindow()
    ui.setupUi(MainWindow)
    MainWindow.show()
    ui.pushButton.clicked.connect(partial(convert, ui))
    ui.comboBox.activated.connect(partial(convert, ui))
    sys.exit(app.exec_())
