关于python：PyQt4字符编码：’ascii’编解码器不能编码字符


PyQt4 character encoding: 'ascii' codec can't encode character

尝试使用下面的脚本加载一个页面，以便我可以使用执行的javascript访问该页面。我想登录并查看结果页面(https://www.thomsononeim.com/v-hom.asp)，同时执行javascript。在python 2.7中，我得到这个错误：

Traceback (most recent call last):
File"C:/Python27/Sample
Programs/Stupid Test.py", line 22, in

print html UnicodeEncodeError: 'ascii' codec can't encode character
u'\xa9' in position 8273: ordinal not
in range(128)

代码如下：

class Render(QWebPage):
    def __init__(self, url):
        self.app = QApplication(sys.argv)
        QWebPage.__init__(self)
        self.loadFinished.connect(self._loadFinished)
        self.mainFrame().load(QUrl(url))
        self.app.exec_()

    def _loadFinished(self, result):
        self.frame = self.mainFrame()
        self.app.quit()

url = 'https://www.thomsononeim.com/s-log_in.asp'
r = Render(url)
html = r.frame.toHtml()
print(html)

这应该有效：

print(html.toUtf8())
