python - How do you serve a dynamically downloaded image to a browser using flask? -

-

i'm working ip camera. can use url such 1 grab static image off camera:

http://username:password@ip_of_camera:port/streaming/channels/1/picture

what want have python/flask download image url when client loads page, , embed image page using img tag.

if have template looks this:

<html>     <head>         <title>test</title>     </head>     <body>         <img src="{{ image }}">     </body> </html>

how replace {{ image }} downloaded image?

would use urllib/requests download image flask's static folder, replace {{ image }} {{ url_for('static', filename="temp_image.png") }}, , delete image static folder when page loads? download someplace else instead (other static folder)? or there other way keeps image in memory?

ps. know it's possible replace {{ image }} url directly, reveals username/password/ip/port of camera client.

i add masking route on flask fetches , serves image directly. lets domain.com/image/user1/cam1

your server typically make http request camera , once receives response, can straight serve response object appropriate mimetype.

in case, image fetched camera resides in ram.

@app.route('image/<userid>/<camid>') def fun(userid,camid):     #  fetch picture appropriate cam     pic = requests.get('http://'+         'username:password'+ # dynamically replace user id / password/ auth         '@ip_of_camera:port'+ #dynamically replace port / ip         '/streaming/channels/1/picture')      # processing of pic here..      return response(pic,mimetype="image/png")

however, if image needs served on , on again, might wanna cache it. in case, pick closer approach.

if want stream camera images, whole different ballgame.
