python 错误 "quote_from_bytes() expected bytes"

Question

所以我有这个代码片段，每当我尝试执行它时都会返回错误。

下面是代码，它应该根据灵活数量的字符串参数进行谷歌图片搜索。

@bot.command()
async def randomimage(*args):
    """Displays a random image of said thing"""
    q = ''

    for arg in enumerate(args):
      q += urllib.parse.quote(arg) + '+'

    f = urllib2.urlopen('http://ajax.googleapis.com/ajax/services/search/images?q=' + q + '&v=1.0&rsz=large&start=1')
    data = json.load(f)
    f.close()

然而，当我尝试执行它时出现此错误:

Traceback (most recent call last):  
File "Python36\lib\site-packages\discord\ext\commands\core.py", line 50, in wrapped
    ret = yield from coro(*args, **kwargs)

File "bot.py", line 39, in randomimage
    q += urllib.parse.quote(arg) + '+'
  File "parse.py", line 775, in quote
    return quote_from_bytes(string, safe)
  File "parse.py", line 800, in quote_from_bytes
    raise TypeError("quote_from_bytes() expected bytes")
TypeError: quote_from_bytes() expected bytes

任何帮助将不胜感激

Answer 1

args 是字符串列表吗？如果是这样，您应该将它们转换为字节，以便 urllib.parse.quote 正常工作。

将 q += urllib.parse.quote(arg) + '+' 更改为 q += urllib.parse.quote(arg.encode('utf-8')) + '+' 或 q += urllib.parse.quote(bytes(arg)) + '+'
