发送HTML表单数据到python Flask

Question

I have a form in one my html files, the code for which is:

<form name="myForm" action="demo_form.asp" onsubmit="return validateForm()" method="post">
Mechanical Turk ID: <input type="text" name="turkID">
</form>

and my python looks like :

@app.route("/upload", methods=['POST', 'GET'])
def upload():
    img = request.files['webcam']
    try:
        text = request.form["turkID"]
    except Exception as inst:
       print type(inst)     # the exception instance
       print inst.args      # arguments stored in .args
       print inst      
    filename = secure_filename(img.filename)
    img.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))
    return "good"

it keeps failing the try part and the output of the exception is:

 <class 'werkzeug.exceptions.BadRequestKeyError'>
('turkID',)
400: Bad Request

I've tried request.form, request.POST.get, request.POST, and cgi, but none are working.

Your HTML is not compatible with the Python code you have provided. You may want to replace demo_form.asp in the action with /upload/ . You are also not sending any file to the field webcam .
