Perhaps you just need to set the 'Access-Control-Allow-Origin' header?
Something like this might work:
# Import necessary files
import serial
from twisted.web.resource import Resource
# Setup Arduino at correct speed
try:
arduino = serial.Serial('/dev/ttyACM0', 9600)
except:
arduino = serial.Serial('/dev/ttyACM1', 9600)
class MoveServo(Resource):
isLeaf = True
permitted_origins = ('http://192.168.1.122:9000',)
def render_GET(self,request):
if origin in (self.permitted_origins):
request.setHeader('Access-Control-Allow-Origin', origin)
try:
# Send value over serial to the Arduino
arduino.write(request.args['value'][0])
return 'Success'
except:
return 'Failure'
resource = MoveServo()
