python - 返回非零退出状态 3 python2.7 子进程 check_output

Question

我已经编写了一些 python 代码来调用执行 curl 命令的子进程，但是我收到错误 Command '['sh', '/tests/curlhttp.sh', 'http://www .bbc.co.uk', '80']' 返回非零退出状态 3 我也尝试通过我的 linux 机器上的终端运行该命令，这似乎没问题。这是我的 python 脚本

def RunCURL(command):
    result = []
    //I get an error when running this
    output = check_output(command.split(" "), stderr=subprocess.STDOUT)
    print output
    # loop through and create a list of lists
    for line in output.splitlines():
        if "=" in line and "time_total" not in line:
            sublist = line.split("=")[0].rstrip().lstrip()
            print sublist + " hello this is curl"
            result.append(sublist)
    return result

这是我要执行的 curl 脚本:

    #!/bin/bash
curl -w '\ncontent_type=%{content_type}\nfilename_effective=%{filename_effective}\nftp_entry_path=%{ftp_entry_path}\nhttp_code=%{http_code}\nhttp_connect=%{http_connect}\nlocal_ip=%{local_ip}\nlocal_port=%{local_port}\nnum_connects=%{num_connects}\nnum_redirects=%{num_redirects}\nredirect_url=%{redirect_url}\nremote_ip=%{remote_ip}\nremote_port=%{remote_port}\nsize_download=%{size_download}\nsize_header=%{size_header}\nsize_request=%{size_request}\nsize_upload=%{size_upload}\nspeed_download=%{speed_download}\nspeed_upload=%{speed_upload}\nssl_verify_result=%{ssl_verify_result}\ntime_appconnect=%{time_appconnect}\ntime_connect=%{time_connect}\ntime_namelookup=%{time_namelookup}\ntime_pretransfer=%{time_pretransfer}\ntime_redirect=%{time_redirect}\ntime_starttransfer=%{time_starttransfer}\ntime_total=%{time_total}\nurl_effective=%{url_effective}\n\n' -o /dev/null -s $1:$2

我从这个博客中获取了这个 curl 脚本，只更改了脚本上的地址字段以接受 url 和端口号:http://blog.kenweiner.com/2014/11/http-request-timings-with-curl.html

这是我在运行从博客本身直接复制到终端的 curl 脚本时得到的结果

content_type=text/html; charset=UTF-8
filename_effective=/dev/null
ftp_entry_path=
http_code=302
http_connect=000
local_ip=10.250.8.99
local_port=60839
num_connects=1
num_redirects=0
redirect_url=https://www.google.co.uk/?gfe_rd=cr&ei=_7gdWOrCLrH38Af1qoKIBw
remote_ip=216.58.204.36
remote_port=443
size_download=262
size_header=258
size_request=78
size_upload=0
speed_download=3535.000
speed_upload=0.000
ssl_verify_result=0
time_appconnect=0.062
time_connect=0.013
time_namelookup=0.001
time_pretransfer=0.062
time_redirect=0.000
time_starttransfer=0.074
time_total=0.074
url_effective=https://www.google.com/

当我把这个脚本放到一个文件中时，我得到了这个

content_type=
filename_effective=/dev/null
ftp_entry_path=
http_code=000
http_connect=000
local_ip=
local_port=0
num_connects=0
num_redirects=0
redirect_url=
remote_ip=
remote_port=0
size_download=0
size_header=0
size_request=0
size_upload=0
speed_download=0.000
speed_upload=0.000
ssl_verify_result=0
time_appconnect=0.000
time_connect=0.000
time_namelookup=0.000
time_pretransfer=0.000
time_redirect=0.000
time_starttransfer=0.000
time_total=0.000
url_effective=https://www.google.com/

查看cUrl error codes看起来 3 表示您的 URL 格式错误。当您在 Python 之外运行它时它是否有效？
