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。
