Running Curl command in python

Question

I'm running the following curl command in CGI script in python using os.system call as below:

os.system('curl -u username:password -X PUT example.com/data/data1.txt -T /diskless/desktop/file.txt\r\n')

Getting the below error when I run the CGI script:

'!rl: Can't open '/diskless/desktop/file.txt') curl: try 'curl --help' or 'curl --manual' for more information.

Any suggestions please?

do you specifically require curl or can you not use other python libraries to handle http requests for you (like python requests for example) — mrkzq

I want to upload a file from my local directory to the http path that I specify. This will be executed in python CGI. Can you give me a sample code — Krish

look at the error - Can't open '/diskless/desktop/file.txt'. do you have permissions on the file you are trying to upload? — mrkzq

Yes, I have. It's the problem with '\r\n' at the end of the command. This '\r\n' is required if you are executing it in a CGI script; otherwise you would get a malformed header error. — Krish

you can use subprocess

import subprocess
command = 'curl -u username:password -X PUT example.com/data/data1.txt -T /diskless/desktop/file.txt\r\n'
p = subprocess.Popen(command, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
out, err = p.communicate()

@lliyan Markov- Any idea on why os.systme() is getting failed if I use '\r\n' at the end of the command. Also, your subprocess.POPEN is getting the following error : p = subprocess.POPEN(command, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE) AttributeError: 'module' object has no attribute 'POPEN'

Sorry, lliyan. There's no error now. But, I don;t see file getting uploaded.

do you actually need to have \r\n at the end of that command?

If we are executing curl command in CGI script using os.system, it's required, otherwise you would get a malformed header error.

try that: command = curl -X POST -d @/diskless/desktop/file.txt http://username:[email protected]/uploadlink/
