using -json_port 8070

[lingogogo]

Thank a lot in advance.

i use -json_port to send the data to website http://localhost:8070
But now i want to transfer the data to my ROS system.
i have some problem for this

#!/usr/bin/python2

import urllib
import json
import ssl
import json
import rospy
from std_msgs.msg import ColorRGBA


ctx = ssl.create_default_context()
ctx.check_hostname = False
ctx.verify_mode = ssl.CERT_NONE

frame_now = 0
#website location
serviceurl = 'http://127.0.0.1:8070'

pub1 = rospy.Publisher('data_from_yolov3' , ColorRGBA , queue_size = 10)


def talker():
    rospy.init_node('get_data_yolo',anonymous = True)
    rate = rospy.Rate(10)

    while not rospy.is_shutdown():
        url = serviceurl
        print('Retrieving', url)

        uh = urllib.urlopen(url)
        data = uh.read().decode()
        print('Retrieved')

        try:
            js = json.loads(data)
           get_data(js)
        except:
            js = None

        if not js or 'status' not in js or js['status'] != 'OK':
             print('==== Failure To Retrieve ====')
             print(data)
 


#functtion
def get_data(distros_dict):
    json_to_variable = []
    global frame_id, class_id,x,y,width,height
    # For every frame.
    for distro in distros_dict:
        filename = distro['filename']
        if len(distro['objects']) != 0:
            # For every detection.
            for obj in range(len(distro['objects'])):
                # Get values.
                frame_id = distro['frame_id']
                frame_now = frame_now + 1
                class_id = distro['objects'][obj]["class_id"]
                x = distro['objects'][obj]["relative_coordinates"]["center_x"]
                y = distro['objects'][obj]["relative_coordinates"]["center_y"]
                width = distro['objects'][obj]["relative_coordinates"]["width"]
                height = distro['objects'][obj]["relative_coordinates"]["height"]
                confidence = distro['objects'][obj]["confidence"]
                # width640
                x = x*1280
                # height480
                y = y*720
                # detect_image real height and width
                width =  width * 1280
                height = height * 720
                # deal with the data
                # And print them.
                #######################
                # publish data
                pub1.publish(x,y,width,height)
                #######################
                print(frame_id, class_id, x, y, width, height, confidence)
              
if __name__ == '__main__' :
try:
talker()
except rospy.ROSInterruptException:
pass
#over

terminal line
Retrieving from 'http://127.0.0.1:8070'

so it cannot open the url.
if anyone can teach me how to solve the problem.
