代码出错了？该怎么办？

Posted 2023-05-15

url = 'https://music.163.com/discover/toplist?id='
a = input('请输入榜单的ID：')
部分代码如下：
a_url = a+url
base_url = 'https://music.163.com/song/media/outer/url?id='
# a = input('请输入歌单的ID：')
file = "C:/Users/Administrator/pycharmProjects/pythonProject1/网易云音乐/" # 保存音乐的文件路径,最后加斜杠
headers = 'user-agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (Khtml, like Gecko) Chrome/86.0.4240.198 Safari/537.36'
# b_url = "https://link.hhtjim.com/163/"
x = requests.session()
list_url = requests.get(a_url, headers=headers).content
xy = BeautifulSoup(list_url, features="lxml")
main = xy.find('ul', 'class': 'f-hide')
ls = main.find_all('a')
for music in ls:
song_id = str(music['href']).replace('/song?id=', '')
w_url = "https://music.163.com/song?id=" + song_id
song_url = base_url + song_id + ".mp3"
# 获取歌曲
song = requests.get(song_url).content
结果：Traceback (most recent call last):

部分代码找问题让我很为难啊，这里应该是你的url拼接的网址有问题，你可以打印出入id后完整网址，把这个网址输入浏览器看看有没有问题。
url = 'https://music.163.com/discover/toplist?id='
a = input('请输入榜单的ID：')
部分代码如下：
a_url = a+url 这里拼接后确定没有问题？
base_url = 'https://music.163.com/song/media/outer/url?id='
# a = input('请输入歌单的ID：') 参考技术A 按f12调试

求助，win10下MDK5编译例程出错，怎么解决

参考技术A 1.检查电脑是否存在病毒，请使用百度卫士进行木马查杀。
2.系统文件损坏或丢失，盗版系统或Ghost版本系统，很容易出现该问题。建议：使用完整版或正版系统。
3.安装的软件与系统或其它软件发生冲突，找到发生冲突的软件，卸载它。如果更新下载补丁不是该软件的错误补丁，也会引起软件异常，解决办法：卸载该软件，重新下载重新安装试试。顺便检查开机启动项，把没必要启动的启动项禁止开机启动。
4.如果检查上面的都没问题，可以试试下面的方法。
