TypeError：需要一個類似字節的對象，而不是'str'python3

Question

在我的項目中，我正在將樣式動態地寫入HTML文件。 我最近從python2遷移到了3。現在它拋出了錯誤，如下日志所示：

代碼段：

 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>')

錯誤日志：

Quit the server with CTRL-BREAK.

TypeError: a bytes-like object is required, not 'str'

Answer 1

如何改變你的

uploaded_file + '.html', "wb")

至

uploaded_file + '.html', "w")

然后您需要在下面轉換行

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

至

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

因為當前它是字節類型
