时隔一个月，使用PyQt5开发了一款浏览器，不但能满足日常网页浏览，还支持一些辅助功能，例如：截图、收藏网址、查看浏览历史、主题颜色设置…来吧~
一．准备工作
1.PyQt5
pyqt5是一套Python绑定Digia QT5应用的框架。它可用于Python 2和3。本教程使用Python 3。Qt库是最强大的GUI库之一。pyqt5的官方网站
https://doc.qt.io/qtforpython-5/。
pyqt5做为Python的一个模块，它有620多个类和6000个函数和方法。这是一个跨平台的工具包，它可以运行在所有主要的操作系统，包括UNIX，Windows，Mac OS。pyqt5是双重许可。开发者可以在GPL和商业许可之间进行选择。安装：
pip install PyQt5
PyQt5官方文档：
https://doc.qt.io/qtforpython-5
2.Qwebengineview
pyqt5 已经抛弃 QtWebKit和QtWebKitWidgets，而使用最新的QtWebEngineWidgets。QtWebEngineWidgets，是基于chrome浏览器内核引擎的。安装：
pip install PyQtWebEngine
QWebEngineView官方文档：
https://doc.qt.io/qtforpython-5/PySide2/QtWebEngineWidgets/QWebEngineView.html
3.PyQt5-tools
PyQt5-tools里面包含了一系列QT开发的GUI工具，能有效减少代码量。
在PyQt中编写UI界面可以直接通过代码来实现，也可以通过Qt Designer来完成。Qt Designer的设计符合MVC的架构，其实现了视图和逻辑的分离，从而实现了开发的便捷。Qt Designer中的操作方式十分灵活，其通过拖拽的方式放置控件可以随时查看控件效果。Qt Designer生成的.ui文件（实质上是XML格式的文件）也可以通过pyuic5工具转换成.py文件。
Qt Designer随PyQt5-tools包一起安装，其安装路径在 “Python安装路径\Lib\site-packages\pyqt5-tools”下。
若要启动Qt Designer可以直接到上述目录下，双击designer.exe打开Qt Designer；或将上述路径加入环境变量，在命令行输入designer打开；或在PyCharm中将其配置为外部工具打开。
二．功能展示
1.主页
浏览器启动后，会自动打开设定好的网页。
2.我的收藏
通过读取本地指定txt文件，显示收藏的链接。
3.浏览历史
此界面记录所有本次浏览历史记录。
4.网页截图
通过调用自带的API实现网页截图。
5.收藏
点击收藏，将网页收藏到我的收藏。
6.复制链接
复制当前浏览器网页链接地址到剪切板。
7.网页放大/缩小
通过点击工具栏按钮和设置中的组合栏对浏览器网页进行缩放操作，同时显示当前浏览器放大比例。
8.设置-基本
在基本设置中可以设置主页、搜索引擎、网页缩放比例。
9.设置-个性
在个性设置中，可以设置主题颜色、UA、语言等。
10.设置-隐私
在隐私设置中，可以清理浏览历史记录、cookie、设置文件下载路径、截图保存路径
三．界面设计
1.主窗口设计
2.设置窗口设计
1.设置-基本
2.设置-个性
3.设置-隐私
3.整体QSS设计
使用QSS，设置浏览器整体颜色风格，设置控件边框颜色、边框角度等视觉展示效果，首次启动默认使用此颜色作为主题颜色。

</RCC>五．总结
本次使用PyQt5制作了一款浏览器，基本实现了一般浏览器的功能，不过还是存在一些不足，例如：
1.所有网页跳转均在主窗口中进行，不支持多页显示和操作
2.不支持视频播放
3.设置里面的部分内容没有实现，比如：语言切换
4.网页收藏格式过于简单，只是文本文件操作，可以使用html格式，便于规范
在此，提出我的解决问题方案：
1.PyQt5中使用QTabwidget标签页，网页跳转时，创建新的标签页。可参考：
python PyQt QtWebEngine实现本窗口跳转+ 新窗口跳转
2.重新编译QtWebEngine。可参考：
解决QtWebEngine无法播放H5中的mp4
3.使用QtLinguist，逐个翻译。可参考：
PyQt5 pycharm配置(2)语言家QtLinguist
4.这个简单，使用Python自带的字符串处理函数，将title放在a标签里，将链接地址放在href中，最后存为.html格式
程序打包好放在了百度云中（密码：8888），欢迎各位使用、测试。思路、代码方面有什么不足欢迎各位大佬指正、批评！能点个赞给我个鼓励吗？
六．附录：开发记录
2021-10-10
1.设计UI界面，用浏览器填充整个窗口，设计菜单栏、工具栏
2.绑定浏览器事件以及对应函数（1）urlChanged：->show_jump_url(url) 展示“加载”进度条、将URL显示在输入框中（2）loadProgress：->show_load_progress(progress) 显示加载进度，设置窗口标题（3）loadFinished:->change_history_state() 改变“前进”，“后退”按钮状态（4）iconChanged：->lambda icon:self.setWindowIcon(icon) 设置窗口图标2021-10-18
1.输入时，判断输入类型，根据输入类型改变按钮标题为“转到”或“搜索” textEdited：->judge_input(text)
2.尝试调用X度搜索建议，但是界面会闪退2021-10-19
1.历史记录URL、title，绑定双击事件、清理缓存
2.收藏记录2021-10-21
QSS整体主题皮肤设置2021-10-23
