Question

我试图在不带Shell = true的情况下运行subprocess.popen，但无法弄清楚如何格式化列表。它始终会失败，并带有无效的url或403。就像它没有设置cookie或标头一样。

示例网址

我解析网址以获取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一起使用的最终字符串

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

这是我尝试格式化的方法，但似乎无法正确处理。

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：

联接的作用看起来是正确的，但似乎无法正确执行。我确实认为由于特殊字符，我需要对Cookie和url加上双引号。只是希望得到一个输出，而在Shell = True的情况下，直到完成它才得到输出。

Answer 1

User-Agent标头和cookie周围的文字引号看起来可疑。我猜你想要

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。
