How to upload file via flask rest-api?

Question

Flask

I'm using the standard file upload feature from the Flask documentation

@app.route('/', methods=['GET', 'POST'])
def index():
    if request.method == 'POST':
        if 'file' not in request.files:
            flash('No file part')
            return redirect(request.url)
        file = request.files['file']
        if file.filename == '':
            flash('NO selected file')
            return redirect(request.url)
        print(file.filename)
        if not allowed_file(file.filename):
            flash("Only JPG file is used")
            return redirect(request.url)
        if file and allowed_file(file.filename):
            filename = secure_filename(file.filename)
            file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))
            img = (os.path.join(app.config['UPLOAD_FOLDER'], filename))
            _, count = performDetect(imagePath=img)
            return redirect(url_for("result", count=count))
    return render_template("index.html")

If you use a browser as a client, then everything works. Now I'm testing uploading via Postman, and when sending I get No file part

Why is this happening? Is it even possible to use this way of uploading files in rest api?

in key add the name of the field, in your case: file
