后端：
def test(request):
import os
import time
t = time.time()
logfilename = time.strftime(‘%Y%m%d%H%M%S‘) + ‘.log‘
# print logfilename
# status, out = os.system("/tmp/sss.sh + ‘ ‘ + ‘test‘>/tmp/%s" % logfilename)
# out = os.system("/tmp/sss.sh ‘test‘>/tmp/%s" % logfilename)
logfilepath = ‘/tmp/%s‘ % logfilename
t = threading.Thread(target=shell_os, args=(logfilename,))
t.setDaemon(True)
t.start()
f = file(‘/tmp/20160903083315.log‘, ‘r+‘)
# time.sleep(10)
# out = f.readline()
# pos = f.tell()
# print out
# f.close()
# return HttpResponse(out)
return render_to_response(‘myajax.html‘, {‘title‘: logfilepath, ‘output‘: ‘test‘,})
import os
def shell_os(logfilename):
out = os.system("/tmp/sss.sh ‘test‘>/tmp/%s" % logfilename)
return out
def myajax(request):
# print request.method
if request.method == ‘POST‘:
print request.method
print request
filepath = request.POST.get(‘filepath‘)
print filepath
pos = request.POST.get(‘pos‘)
print pos
f = file(filepath, ‘r+‘)
print ‘-------------‘
f.seek(int(pos))
print ‘-------------‘
out = f.readline()
pos = f.tell()
f.close()
print ‘==========out‘, out, pos
ret = {‘out‘: out, ‘posh‘: pos}
return HttpResponse(json.dumps(ret))
else:
return HttpResponse(‘GET‘)
