公众号获取临时素材为什么会出现乱码？

# TODO: 获取临时素材 get (疑问?主要是返回结果乱码问题)
def get_media_id(request):
    publicName = request.POST.get('publicName', None)
    media_id = request.POST.get("media_id", None)
    url = 'https://api.weixin.qq.com/cgi-bin/media/get?'
    params = {
        "access_token": get_token(**{"publicName": publicName}),  # 获取token
        "media_id": media_id,
    }
    res = requests.get(url, params=params)
    return HttpResponse(res.text)
