Question

在我的项目中，我动态地将样式写入HTML文件。我最近从python2迁移到3.现在它抛出了一个错误，如下所示：

代码段：

 html_text = markdown(html_content, output_format='html4')
    css = const.URL_SCHEME + "://" + request_host + '/static/css/pdf.css'
    css = css.replace('\\', "/")
    # HTML File Output
    #print 'Started Html file generated' + const.CRUMBS_TIMESTAMP
    html_file = open(os.getcwd() + const.MEDIA_UPLOADS + uploaded_file_name + '/output/' +
                     uploaded_file + '.html', "wb")
    #print(html_file)
    html_file.write('<style>')
    html_file.write(urllib.request.urlopen(css).read())
    html_file.write('</style>')

错误日志：

Quit the server with CTRL-BREAK.

    html_file.write('<style>')
TypeError: a bytes-like object is required, not 'str'

Answer 1

如何更改

uploaded_file + '.html', "wb")

到

uploaded_file + '.html', "w")

然后你需要转换下面的行

   html_file.write(urllib.request.urlopen(css).read())

到

   html_file.write(urllib.request.urlopen(css).read().decode("utf-8"))

因为目前它是字节

TypeError：需要类似字节的对象，而不是＆＃39; str＆＃39; python3
