Execute curl command within a Python script

Question

I am trying to execute a curl command within a python script   If I do it in the terminal  it looks like this   curl -X POST -d     nw src    10 0 0 1 32    nw dst    10 0 0 2 32    nw proto    ICMP    actions    ALLOW    priority    10    http   localhost 8080 firewall rules 0000000000000001   I ve seen recommendations to use pycurl  but I couldn t figure out how to apply it to mine   I tried using   subprocess call        curl        -X        POST        -d       flow x       http   localhost 8080 firewall rules 0000000000000001       and it works  but is there a better way

Try with subprocess  CurlUrl  curl  https   www example com   -H  Connection  keep-alive  -H  Cache-            Control  max-age 0  -H  Origin  https   www example com  -H  Accept-Encoding             gzip  deflate  br  -H  Cookie  SESSID ABCDEF  --data-binary  Pathfinder  --            compressed    Use getstatusoutput to store the results  status  output   subprocess getstatusoutput CurlUrl

Rephrasing one of the answers in this post  instead of using cmd split    Try to use    import shlex  args   shlex split cmd    Then feed args to subprocess Popen   Check this doc for more info  https   docs python org 2 library subprocess html popen-constructor

You could use urllib as  roippi said   import urllib2 data      nw src    10 0 0 1 32    nw dst    10 0 0 2 32    nw proto    ICMP    actions    ALLOW    priority    10    url    http   localhost 8080 firewall rules 0000000000000001  req   urllib2 Request url  data    Content-Type    application json    f   urllib2 urlopen req  for x in f      print x  f close

Don t  I know  that s the  quot answer quot  nobody wants  But if something s worth doing  it s worth doing right  right  This seeming like a good idea probably stems from a fairly wide misconception that shell commands such as curl are anything other than programs themselves  So what you re asking is  quot how do I run this other program  from within my program  just to make a measly little web request  quot   That s crazy  there s got to be a better way right  Uxio s answer works  sure  But it hardly looks very Pythonic  does it  That s a lot of work just for one little request  Python s supposed to be about flying  Anyone writing that is probably wishing they just call d curl    it works  but is there a better way   Yes  there is a better way  Requests  HTTP for Humans  Things shouldn   t be this way  Not in Python   Let s GET this page  import requests res   requests get  https   stackoverflow com questions 26000336    That s it  really  You then have the raw res text  or res json   output  the res headers  etc  You can see the docs  linked above  for details of setting all the options  since I imagine OP has moved on by now  and you - the reader now - likely need different ones  But  for example  it s as simple as  url        http   example tld  payload      key     val    headers      res   requests post url  data payload  headers headers   You can even use a nice Python dict to supply the query string in a GET request with params     Simple and elegant  Keep calm  and fly on

You can use below code snippet import shlex import subprocess import json  def call curl curl       args   shlex split curl      process   subprocess Popen args  shell False  stdout subprocess PIPE  stderr subprocess PIPE      stdout  stderr   process communicate       return json loads stdout decode  utf-8      if   name         main         curl      curl - X     POST - d        quot nw src quot    quot 10 0 0 1 32 quot    quot nw dst quot    quot 10 0 0 2 32 quot    quot nw proto quot    quot ICMP quot    quot actions quot    quot ALLOW quot    quot priority quot    quot 10 quot        http     localhost  8080   firewall   rules   0000000000000001         output   call curl curl      print output

If you are not tweaking the curl command too much you can also go and call the curl command directly  import shlex cmd      curl -X POST -d     nw src    10 0 0 1 32    nw dst    10 0 0 2 32    nw proto    ICMP    actions    ALLOW    priority    10    http   localhost 8080 firewall rules 0000000000000001    args   shlex split cmd  process   subprocess Popen args  shell False  stdout subprocess PIPE  stderr subprocess PIPE  stdout  stderr   process communicate
