I have jar file when executed will print out the output on the terminal, Im not sure how can i pass the jar file output as a json file.
The code below just print the jar file output on the terminal
subprocess.Popen(['java', '-jar', '/home/myfolder/collect.jar'])
I'm thinking of below but no idea to start with...
with open('collect.json', 'w') as fp:
xxxxxxxxxxx
Hope someone could advise further. Thank you.
This should do the trick. If you look at the subprocess documentation you can see that check_output runs a command with arguments and return its output as a byte string.
import multiprocessing as mp
import subprocess
command = "java -jar /home/myfolder/collect.jar"
def runCommand(q):
commandOutput = subprocess.check_output(command.split()).decode("utf-8")
q.put(commandOutput)
q = mp.Queue()
commandProcess = mp.Process(target=runCommand, args=(q, ))
commandProcess.start()
output = q.get()
print(output)
with open('collect.json', w) as fp:
fp.write(output)
Didn't run the code, but should work.
You can try something like this
with open('collect.json','w') as fp :
subprocess.Popen('java -jar .//home/myfolder/collect.jar',stdout=fp).wait()
for further information, see this question How to get the output from .jar execution in python codes?
I hope this helped.
