Postman, Python and passing images and metadata to a web service

Question

this is a two-part question: I have seen individual pieces discussed, but can\'t seem to get the recommended suggestions to work together. I want to create a web service to

Answer 1

Make sure `request.files['Image'] contains the image you are sending and follow http://flask.pocoo.org/docs/1.0/patterns/fileuploads/ to save the file to your file system. Something like

file = request.files['Image']
file.save('./test_image.jpg')

might do what you want, while you will have to work out the details of how the file should be named and where it should be placed.

Answer 2

Pardon the almost blog post. I am posting this because while you can find partial answers in various places, I haven't run across a complete post anywhere, which would have saved me a ton of time. The problem is you need both sides to the story in order to verify either.

So I want to send a request using Postman to a Python/Flask web service. It has to have an image along with some metadata.

Here are the settings for Postman (URL, Headers):

And Body:

Now on to the web service. Here is a bare bones service which will take the request, print the metadata and save the file:

from flask import Flask, request

app = Flask(__name__)        

# POST - just get the image and metadata
@app.route('/RequestImageWithMetadata', methods=['POST'])
def post():
    request_data = request.form['some_text']
    print(request_data)
    imagefile = request.files.get('imagefile', '')
    imagefile.save('D:/temp/test_image.jpg')
    return "OK", 200

app.run(port=5000)

Enjoy!
