在Linux系统下进行编译。
Linux系统安装PyQt5
sudo apt-get install python3-pyqt5
打开网页：
import webbrowser
webbrowser.open('http://www.baidu.com/')
用pyqt5打开网页：
import sys
from PyQt5.QtCore import QUrl
from PyQt5.QtWidgets import QApplication
from PyQt5.QtWebEngineWidgets import QWebEnginePage, QWebEngineView
app = QApplication(sys.argv)
browser = QWebEngineView()
browser.load(QUrl("http://www.baidu.com/"))
browser.show()
app.exec_()
简单界面的浏览器：
from PyQt5.QtWidgets import QApplication, QWidget, QPushButton ,QDesktopWidget ,QLabel ,QGridLayout
import webbrowser ,sys
class Ui_MainWindow(QWidget):
item_name = "PyQt打开外部链接"
def __init__(self):
super().__init__()
self.initUI()
def initUI(self):
self.tips_1 = QLabel("网站：http://www.baidu.com/");
self.tips_1.setOpenExternalLinks(True)
self.btn_webbrowser = QPushButton('webbrowser效果', self)
self.btn_webbrowser.clicked.connect(self.btn_webbrowser_Clicked)
grid = QGridLayout()
grid.setSpacing(10)
grid.addWidget(self.btn_webbrowser, 1, 0)
grid.addWidget(self.tips_1, 2, 0)
self.setLayout(grid)
self.resize(250, 150)
self.setMinimumSize(266, 304);
self.setMaximumSize(266, 304);
self.center()
self.setWindowTitle(self.item_name)
self.show()
def btn_webbrowser_Clicked(self):
webbrowser.open('http://www.baidu.com/')
def center(self):
qr = self.frameGeometry()
cp = QDesktopWidget().availableGeometry().center()
qr.moveCenter(cp)
self.move(qr.topLeft())
if __name__ == "__main__":
app = QApplication(sys.argv)
a = Ui_MainWindow()
sys.exit(app.exec_())
有登录界面的浏览器：
注意：下面代码中的jl.png文件和需要编译的.py文件放在同一个文件夹下。
该浏览器需要注册账号，输入登录密码，方能跳转到百度网页。
