popen流链接的列表格式

Question

我试图在没有Shell=true的情况下运行Shell=true，但不知道如何格式化我的列表。对于无效的url或403，它总是会失败。就像它没有设置曲奇或标题一样。

示例url

https://vodus-i-video-xxx.xxx.net/vodus/1d9cfcbc-8469-4c9f-b44a-6412091b733d/NoADs_IND_SEA_720_pre1.ism/QualityLevels(4740905)/Manifest(video,format=m3u8-aapl-v3,audiotrack=aac_UND_2_127,filter=chromecast)?hdnea=st=1535729260~exp=1535729440~acl=/*~hmac=977cba9e480bcdb7b89033488f37679b4a6906f8f7a981a055b88a0802012c71&hdcore=2.11.3|Connection=keep-alive&User-Agent=Firefox|Connection=keep-alive&User-Agent=Firefox

我解析url以获得cookie:：

"hdnea=st=1535729260~exp=1535729440~acl=/*~hmac=977cba9e480bcdb7b89033488f37679b4a6906f8f7a981a055b88a0802012c71&hdcore=2.11.3;path=/; domain=livemain-i-video-xxx.xxx.net;86400s"

将与Shell=true一起工作的最终字符串

streamlink --player-external-http --player-external-http-port 10000 --http-header "User-Agent=Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:61.0) Gecko/20100101 Firefox/61.0" --http-cookie "hdnea=st=1535729260~exp=1535729440~acl=/*~hmac=977cba9e480bcdb7b89033488f37679b4a6906f8f7a981a055b88a0802012c71&hdcore=2.11.3;path=/; domain=livemain-i-video-xxx.xxx.net;86400s" "hlsvariant://https://vodus-i-video-xxx.xxx.net/vodus/1d9cfcbc-8469-4c9f-b44a-6412091b733d/NoADs_IND_SEA_720_pre1.ism/QualityLevels(4740905)/Manifest(video,format=m3u8-aapl-v3,audiotrack=aac_UND_2_127,filter=chromecast)?hdnea=st=1535729260~exp=1535729440~acl=/*~hmac=977cba9e480bcdb7b89033488f37679b4a6906f8f7a981a055b88a0802012c71&hdcore=2.11.3|Connection=keep-alive&User-Agent=Firefox|Connection=keep-alive&User-Agent=Firefox" best

这就是我试图格式化的方式，但似乎不能正确地完成它。

stream_url="https://vodus-i-video-nfl.akamaized.net/vodus/1d9cfcbc-8469-4c9f-b44a-6412091b733d/NoADs_IND_SEA_720_pre1.ism/QualityLevels(4740905)/Manifest(video,format=m3u8-aapl-v3,audiotrack=aac_UND_2_127,filter=chromecast)?hdnea=st=1535729260~exp=1535729440~acl=/*~hmac=977cba9e480bcdb7b89033488f37679b4a6906f8f7a981a055b88a0802012c71&hdcore=2.11.3|Connection=keep-alive&User-Agent=Firefox|Connection=keep-alive&User-Agent=Firefox"
urlsplit = stream_url.split('?')
getcookie = urlsplit[1].split('|')
cookie = getcookie[0] 
cmd = [
"streamlink",
"--player-external-http",
"--player-external-http-port", 
"%s" %(port),
"--http-header",
"\"User-Agent=Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:61.0) Gecko/20100101 Firefox/61.0\"",
"--http-cookie",
"\"%s" %(cookie) + ";path=/;domain=livemain-i-video-nfl.akamaized.net;86400s\"",
"%s" %(streamtest),   
"best"
]
    logger.info("Running cmd: %s" % " ".join(cmd))
    proc = subprocess.Popen(cmd, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
    output, err = proc.communicate()
    logging.info(output)

我得到的输出是：

信息:root:Running: streamlink -player-外部-player-外部-http-port 15000 --http-header "User-Agent=Mozilla/5.0 (Windows 10.0；Win64；x64；rv:61.0) Gecko/20100101 Firefox/61.0“-http-cookie- 信息:根:cli流链接正在以root的形式运行！注意!cli为Unable ://https://livemain-i-video-xxx.xxx.net/ch16/7fd8a3f6-5dee-4ed1-b23f-7398684ff5bd/7fd8a3f6-5dee-4ed1-b23f-7398684ff5bd.ism/QualityLevels(2200000)/Manifest(video,format=m3u8-aapl-v3,audiotrack=audio,filter=chromecast-live)错误找到匹配的插件hls :无法打开https://livemain-i-video-xxx.xxx.net/ch16/7fd8a3f6-5dee-4ed1-b23f-7398684ff5bd/7fd8a3f6-5dee-4ed1-b23f-7398684ff5bd.ism/QualityLevels(2200000)/Manifest(video,format=m3u8-aapl-v3,audiotrack=audio,filter=chromecast-live) (403个客户端错误: URL：https://livemain-i-video-xxx.xxx.net/ch16/7fd8a3f6-5dee-4ed1-b23f-7398684ff5bd/7fd8a3f6-5dee-4ed1-b23f-7398684ff5bd.ism/QualityLevels(2200000)/Manifest(video,format=m3u8-aapl-v3,audiotrack=audio,filter=chromecast-live)被禁止)

连接看起来是正确的，但似乎不太正确。我确实认为我需要双引号的曲奇和url，因为特殊的字符。我只是希望得到一个输出，而在Shell=True中，直到输出完成后才会得到输出。

Answer 1

用户代理头和cookie周围的文字引号看起来可疑。我猜你想

cmd = [
    "streamlink",
    "--player-external-http",
    "--player-external-http-port", 
    str(port),
    "--http-header",
    "User-Agent=Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:61.0) Gecko/20100101 Firefox/61.0",
    "--http-cookie",
    "%s;path=/;domain=livemain-i-video-nfl.akamaized.net;86400s"%(cookie),
    streamtest,
    "best"
]

还请注意，我们如何避免使用%字符串格式将某些内容转换为已经是字符串的字符串。
