Я пытаюсь отправить изображение на виртуальную машину Azure и получить сообщение. Код сервера:
from flask import Flask, request, Response
import jsonpickle
import numpy as np
import cv2
# Initialize the Flask application
app = Flask(__name__)
# route http posts to this method
@app.route('/api/test', methods=['POST'])
def test():
r = request
# convert string of image data to uint8
nparr = np.fromstring(r.data, np.uint8)
# decode image
img = cv2.imdecode(nparr, cv2.IMREAD_COLOR)
# build a response dict to send back to client
response = {'message': 'image received. size={}x{}'.format(img.shape[1], img.shape[0])
}
# encode response using jsonpickle
response_pickled = jsonpickle.encode(response)
return Response(response=response_pickled, status=200, mimetype="application/json")
# start flask app
app.run(host="0.0.0.0", port=5000)
Код клиента:
from __future__ import print_function
import requests
import json
import cv2
addr="http://azure_vm_ip:5000/"
test_url = addr + '/api/test'
# prepare headers for http request
content_type = 'image/jpeg'
headers = {'content-type': content_type}
img = cv2.imread('image.jpg')
# encode image as jpeg
_, img_encoded = cv2.imencode('.jpg', img)
# send http request with image and receive response
response = requests.post(test_url, data=img_encoded.tostring(), headers=headers)
# decode response
print(json.loads(response.text))
# expected output: {u'message': u'image received. size=124x124'}
Я получаю эту ошибку: ConnectionError: ('Connection aborted.', ConnectionResetError(10054, 'An existing connection was forcibly closed by the remote host', None, 10054, None))
Я могу запустить тот же код на своем локальном хосте и работает хорошо. Но это не работает на ВМ. Что я делаю не так?
