#Python 🐍 – Webserver App to receive binay content and save this as a file locally

Hi !

The title of the post is enough to describe the next piece of code:

Webserver App to receive binay content and save this as a file locally

Here it is.

from flask import Flask, request, jsonify
app = Flask(__name__)
imgCounter = 0
@app.route("/save", methods=["POST"])
def save_file():
# log a line
print("save file requested")
# get the byte array from the request body
bodyByteArray = request.get_data()
# increment the counter
global imgCounter
imgCounter += 1
# define image name using the counter
imgName = "img" + str(imgCounter) + ".jpg"
# save bodyByteArray to disk
with open(imgName, "wb") as f:
f.write(bodyByteArray)
return jsonify({'msg': 'success', 'file name': [imgName]})
if __name__ == "__main__":
app.run(host="127.0.0.1", port=5000, debug=True)

And, while we perform some posts to the http endpoint, we can start to see the local files in the same folder of the python file.

save files locally

Happy coding!
