【问题描述】：

我正在使用 PyQt4 使用 QtWebKit 创建自定义浏览器，但我一直在保存浏览器中的书签。有谁知道如何做到这一点？

【参考方案1】：

您对如何完成此操作有点含糊，所以我会说我们想使用从名为 bookmarks_Btn 的 UI 文件导入的按钮。您需要使用pickle 模块。

这是示例代码...

from PyQt4 import QtCore, QtGui, QtWebKit, uic
import pickle

class window(QtGui.QWidget):
    def __init__(self, parent=None):
        super(httpWidget, self).__init__(parent)
        self.ui = uic.loadUi('mybrowser.ui')
        self.ui.setupUi(self)      

    def bookmarksLoad(self):
        print 'Loading bookmarks'
        try:
            bookOpen = open('bookmarks.txt', 'rb')
            bookmarks = pickle.load(bookOpen)
            bookOpen.close()
            print bookmarks # Not necessary, but for example purposes

            # Here you decide how "bookmarks" variable is displayed.

        except:
            bookOpen = open('bookmarks.txt', 'wb')
            bookmarks = 'http://www.***.com'
            bookWrite = pickle.dump(bookmarks, bookOpen)
            bookOpen.close()
            print bookmarks # Not necessary, but for example purposes

            # Here you decide how "bookmarks" variable is displayed.

     QtCore.QObject.connect(self.ui.bookmarks_Btn, QtCore.SIGNAL('clicked()'), self.bookmarksLoad)
    self.ui.show()

def bookmarks():
    url = input 'Enter a URL: '
    bookOpen = open('bookmarks.txt', 'wb')
    bookOpen.write(url)
    bookOpen.close()
    print 'Website bookmarked!'


if __name__ == '__main__':
    app = QtGui.QApplication(sys.argv)
    run = window()
    bookmarks()
    sys.exit(app.exec_())

# You add on here, for example, deleting bookmarks.

但是，如果您希望从地址栏（名为 address）中检索它，请进行以下更改...

# In the bookmarks function...
global url # Add at beginning
# Remove the input line.

# Add at end of __init__ in window class:
url = self.ui.address.text()
global url

这几乎是基础。请注意，我通常使用 Python 3 和 PyQt5 进行编程，所以如果有任何错误，请告诉我:)
