【问题描述】：
我无法自动检索 Youtube 视频。这是代码。问题是最后一部分。 download = urllib.request.urlopen(download_url).read()
# Youtube video download script
# 10n1z3d[at]w[dot]cn
import urllib.request
import sys
print("\n--------------------------")
print (" Youtube Video Downloader")
print ("--------------------------\n")
try:
video_url = sys.argv[1]
except:
video_url = input('[+] Enter video URL: ')
print("[+] Connecting...")
try:
if(video_url.endswith('&feature=related')):
video_id = video_url.split('www.youtube.com/watch?v=')[1].split('&feature=related')[0]
elif(video_url.endswith('&feature=dir')):
video_id = video_url.split('www.youtube.com/watch?v=')[1].split('&feature=dir')[0]
elif(video_url.endswith('&feature=fvst')):
video_id = video_url.split('www.youtube.com/watch?v=')[1].split('&feature=fvst')[0]
elif(video_url.endswith('&feature=channel_page')):
video_id = video_url.split('www.youtube.com/watch?v=')[1].split('&feature=channel_page')[0]
else:
video_id = video_url.split('www.youtube.com/watch?v=')[1]
except:
print("[-] Invalid URL.")
exit(1)
print("[+] Parsing token...")
try:
url = str(urllib.request.urlopen('http://www.youtube.com/get_video_info?&video_id=' + video_id).read())
token_value = url.split('video_id='+video_id+'&token=')[1].split('&thumbnail_url')[0]
download_url = "http://www.youtube.com/get_video?video_id=" + video_id + "&t=" + token_value + "&fmt=18"
except:
url = str(urllib.request.urlopen('www.youtube.com/watch?v=' + video_id))
exit(1)
v_url=str(urllib.request.urlopen('http://'+video_url).read())
video_title = v_url.split('"rv.2.title": "')[1].split('", "rv.4.rating"')[0]
if '"' in video_title:
video_title = video_title.replace('"','"')
elif '&' in video_title:
video_title = video_title.replace('&','&')
print("[+] Downloading " + '"' + video_title + '"...')
try:
print(download_url)
file = open(video_title + '.mp4', 'wb')
download = urllib.request.urlopen(download_url).read()
print(download)
for line in download:
file.write(line)
file.close()
except:
print("[-] Error downloading. Quitting.")
exit(1)
print("\n[+] Done. The video is saved to the current working directory(cwd).\n")
有一条错误消息：（感谢 Wooble）

【问题讨论】：
-
你真的认为你可以抓住 Youtube 流并将其保存为 mp4 文件吗？尤其是尝试通过二进制流
for line in download看起来很有趣。 -
Tim，首先这不是我的代码，我只是为 python3k 修改了它。其次，如果我在浏览器中输入网址，我可以将其保存为 mp4。你看起来很聪明，那你建议我怎么做？
-
错误似乎在这里。那是服务器给你的错误。这是“禁止的”。
-
没错，但如果我在浏览器中手动输入网址，它可以工作，我可以下载它。
-
你能把这个程序的整个输出贴出来吗？我对打印语句输出的内容感兴趣。
