1.环境安装：
1.安装pyQt5 pip3 install pyQt5
2.安装设计器 pip3 install pyQt5-tools (英文版的) 我是用的是自己Windows上安装的qt-unified软件
3.qt-unified安装，下载地址 https://www.qt.io/
2.qt-unified软件设计界面
新建项目—>Qt—>From
根据左边菜单栏上的控件直接拖到窗口上布局 设计如下界面：
保存文件，命令行切换到保存的.ui文件目录执行如下命令将.ui文件转化py文件
pyuic5 -o mainwindow.py mainwindow.ui
其中，-o 后的参数为输出文件的名称 -o 后第二个参数即为生成的ui文件的名称，报错请注意环境变量
这个时候运行会报错，所以还需要配置几个步骤。
from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtWidgets import QFileDialog,QMessageBox
import sys
if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)
MainWindow = QtWidgets.QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(MainWindow)
MainWindow.show()
sys.exit(app.exec_())
然后成功运行，弹出界面。
这个时候，我们要把按钮和输入框的改造下，使其能够交互起来。
-
QPushButton的信号槽连接：self.choose_file.clicked.connect(self.open_file)，传入的是点击后执行的方法。
-
获取QLineEdit里面的文本：self.cookie_edit.text()。
-
将文案输出到QTextBrowser组件中显示：self.message_show.append('爬取全部文章成功\n')。
-
判断复选框是否选中self.only_name.isChecked()，返回的是true/false。
运行中我发现，每次执行的时候，QTextBrowser组件中的文案，不能像print()方法一样，一行一行的输出，每次都是要等到全部执行完后，一次性输出。这个不符合我设计QTextBrowser组件的初衷。于是我又去问了问怎么样才能让QTextBrowser组件中的文案一行一行的输出。
最终多方尝试后，解决了这个问题，就是加入这句代码QApplication.processEvents()，可以将这句代码放入循环中，就能做到界面的实时刷新了。
在复杂操作的过程中频繁调用QApplication.processEvents()。这个函数告诉Qt处理所有那些还没有被处理的各类事件，然后将控制权返还给调用者。
实际上QApplication.exec()就是一个不停调用processEvents()函数的while循环。
