python curl 执行带参数的命令

Question

我需要执行以下命令

curl -v -H 'X-Auth-User: myaccount:me' -H 'X-Auth-Key: secretpassword' http://localhost:8080/auth/v1.0/

当我从终端运行它时，它运行良好。并给我如下结果

* About to connect() to localhost port 8080 (#0)
*   Trying ::1...
* Connection refused
*   Trying 127.0.0.1...
* Connected to localhost (127.0.0.1) port 8080 (#0)
> GET /auth/v1.0/ HTTP/1.1
> User-Agent: curl/7.29.0
> Host: localhost:8080
> Accept: */*
> X-Auth-User: myaccount:me
> X-Auth-Key: secretpassword
> 
< HTTP/1.1 200 OK
< X-Storage-Url: http://localhost:8080/v1/AUTH_myaccount
< X-Auth-Token: AUTH_tk8bf07349d36041339450f0b46a2adc39
< Content-Type: text/html; charset=UTF-8

* Connection #0 to host localhost left intact

但我需要从 python 运行它。我通过以下方式使用了 subprocess.call 和 subprocess.popen

import subprocess
subprocess.call(["curl", "-v -H 'X-Auth-User: myaccount:me' -H 'X-Auth-Key: secretpassword' http://localhost:8080/auth/v1.0/"], shell=False)

但是我遇到了以下错误

curl: option -v -H 'X-Auth-User: myaccount:me' -H 'X-Auth-Key: secretpassword' http://localhost:8080/auth/v1.0/: is unknown
curl: try 'curl --help' or 'curl --manual' for more information

使用打开

result = subprocess.Popen(["curl", "-v -H 'X-Auth-User: myaccount:me' -H 'X-Auth-Key: secretpassword' http://localhost:8080/auth/v1.0/"])
print(result)

并为此得到错误

curl: option -v -H 'X-Auth-User: myaccount:me' -H 'X-Auth-Key: secretpassword' http://localhost:8080/auth/v1.0/: is unknown
curl: try 'curl --help' or 'curl --manual' for more information
<subprocess.Popen object at 0x7fd003d82cd0>

如何解决这个问题？？？

由于call需要传递一个命令行参数数组，你可以自己拆分命令行，这样调用:

subprocess.call([
    "curl", "-v", "-H", "X-Auth-User: myaccount:me", "-H", 
    "X-Auth-Key: secretpassword", "http://localhost:8080/auth/v1.0/"
], shell=False)
