【问题描述】：
我创建了一个简单的烧瓶应用程序来显示正在远程服务器上执行的一些图像分析的结果。
另一个应用把图片分析结果放在output.jpg，我想通过访问和地址http://localhost:5005/image_analysis_result来显示
只需参考函数get_image_analysis_result()：
这是简单的 Flask 应用：
from flask import Flask, json, request
import requests
import socket
from datetime import date, datetime
from requests.models import Response
import os
JADE_REMOTE_IP = "10.1.0.8"
JADE_REMOTE_PORT = "7778"
IMAGE_RESULT_PATH = "/root/nana/nana/jade/jade/nana_edge_ai/nana_edge_ai/static/outputs/output.jpg"
def returnPublicIP():
h_name = socket.gethostname()
IP_address = socket.gethostbyname(h_name)
return IP_address
#TODO: the URLs in services JSON need to be auto generated to append UE capabilities
services =[{"id": 1,"type": "image_analysis","url": "http://"+returnPublicIP()+":5000/image_analysis"}]
#TODO: the URLs in services JSON need to be auto generated to append gNodeB capabilities
image_result = [{"result_url":"http://"+JADE_REMOTE_IP+":"+JADE_REMOTE_PORT+"/acc"}]
class MockResponse(Response):
def __init__(self,url='http://example.com', headers={'Content-Type':'text/html; charset=UTF-8'},status_code=200,reason = 'Success', _content = 'Some html goes here',json_ = None,encoding='UTF-8'):
self.url = url
self.headers = headers
if json_ and headers['Content-Type'] == 'application/json':
self._content = json.dumps(json_).encode(encoding)
else:
self._content = _content.encode(encoding)
self.status_code = status_code
self.reason = reason
self.encoding = encoding
api = Flask(__name__)
def get_raw_request(request):
request = request.prepare() if isinstance(request, requests.Request) else request
headers = '\r\n'.join(f'{k}: {v}' for k, v in request.headers.items())
body = '' if request.body is None else request.body.decode() if isinstance(request.body, bytes) else request.body
return f'{request.method} {request.path_url} HTTP/1.1\r\n{headers}\r\n\r\n{body}'
@api.route('/services', methods=['GET'])
def get_services():
return json.dumps(services)
#References: requests API : https://realpython.com/python-requests/
#References: #https://www.w3schools.com/python/ref_requests_response.asp
@api.route('/image_analysis', methods=['POST'])
def get_image_analysis():
headers = {'User-Agent': 'Test'}
#NEED TO SETUP WSIG JADE ADD-ON response = requests.get("http://"+JADE_REMOTE_IP+":"+JADE_REMOTE_PORT+"/acc")
print(response.text)
return response
#JUST LOOK AT THIS FUNCTION
@api.route('/image_analysis_result', methods=['GET'])
def get_image_analysis_result():
headers = {'User-Agent': 'Test'}
#1) result path
path = IMAGE_RESULT_PATH
# Check whether the specified path exists or not
isExist = os.path.exists(path)
if (isExist==True):
content = "<!DOCTYPE html><html><body><h1>sent message</h1><p><image width='100%' height='100%' src='{{url_for('static',filename = 'outputs/output.jpg')}}' ></p></body></html>"
else:
content = "<!DOCTYPE html><html><body><h1>sent message</h1><p>NO RESULT</p></body></html>"
mock_response = MockResponse(
headers={'Content-Type' :'application/html'},
status_code=200,
json_=json,
reason='Success',
_content=content)
return mock_response.content
if __name__ == '__main__':
api.run(host='0.0.0.0',port=5005, debug=True)
结果是一个损坏的img标签？
并且 Flask 服务器日志显示：
* Detected change in '/root/nana/nana/jade/jade/nana_edge_ai/nana_edge_ai/nanaTestFlaskApi.py', reloading
* Restarting with stat
* Debugger is active!
* Debugger PIN: 195-909-187

如何修复图像输出？
