Twisted SSH curl "'CreateProcess', 'The system cannot find the file specified."

I've used twisted to make an SSH server similar to the one shown here. I attempted to add curl functionality to it like so:

class CurlProcessProtocol(protocol.ProcessProtocol):
    def connectionMade(self):
        self.transport.closeStdin()

def do_curl(self, *args):
    "Sets up a download"
    curlProcess = CurlProcessProtocol()
    args = tuple(['curl'])+args
    reactor.spawnProcess(curlProcess, 'curl', args)

I have the files necessary for curl to run in the same directory as my program. When I connect to the SSH server and attempt a curl command, I get the following error: Error: (2, 'CreateProcess', 'The system cannot find the file specified.') I tried appending os.getcwd()+ before 'curl' to no avail.

Solution

  • Alright, so I needed to be more specific. Here is a working do_curl. I had to add a "\" after getcwd() and a ".exe" after curl.

    def do_curl(self, *args):
    "Sets up a download"
    curlProcess = CurlProcessProtocol()
    args = tuple([os.getcwd()+'\curl.exe'])+args
    reactor.spawnProcess(curlProcess, os.getcwd()+'\curl.exe', args)
