How can I upload files in Postman?

Question

I want to pass images through POST method in POSTMAN but I get None type response in the line request.files['image']

I have tried a number of different things but I am not able to solve the problem.

from flask import Flask,jsonify
from flask import request
import face_recognition
import json

app = Flask(__name__)

@app.route('/')
def index():
   return ''


@app.route('/valid_faces', methods=['POST'])


def POST():
    if request.method == 'POST':

    # getting the images url from the request
    print('....')
    name1 = request.files['file'] if request.files.get('file') else None
    print('....')
    print (name1)        # name2 = request.form.get('name2')

    # map the url to the ones in the folder images
    firstImage = name1


    # loading the image inside a variable
    firstImage = face_recognition.load_image_file(firstImage)




    result=face_recognition.face_locations(firstImage)


    if result:
        # x={'valid_faces':True}
        # return jsonify(x)
        return "True"
    else:
        # x={'valid_faces':False}
        # return jsonify(x)
        return "False"


if __name__ == "__main__":
    app.run(debug=True)

Answer 1

In my case Postman set empty first value for FileStorage object in request.files . You can check this using:

print(str(request.files))

And in case of empty index instead

file = request.files['file']

try to use

file = request.files['']

Answer 2

In Postman, do the following:

• Set the method to POST
• Set the body type to form-data
• Establish Key/Value pairs for input. Set the value for the Key to "file"
• Mouse over the Key field and choose Text or File from the drop-down menu
• Click Send to process the request
