No matter what I do I keep getting AttributeError: 'str' object has no attribute 'read'

Question

No matter what I do I keep getting AttributeError: 'str' object has no attribute 'read'. I think it has to do with my variable ajax_data, so I made some attempts to try to fix it. Here are some attempts I have made to solve this error:

ajax_data = json.load(request.data.read().decode('utf-8')) 
ajax_data = json.loads(request.data.read().decode('utf-8'))
ajax_data = json.loads(request.data.read())
ajax_data = json.load(request.data.read())
ajax_data = json.load(request.data.decode())
ajax_data = json.loads(request.data.decode())

Here is my code:

@portfolio_app.route('/postContactForm', methods=['POST'])
def postContactForm():
    #Gets the data sent from frontend  
    ajax_data = json.load(request.data.decode()) 
    print(ajax_data)

    # Connect to DB
    db = connectToDB()

    #Choose collection name
    contact_data = db.contact_data
    print(contact_data)

    #Inserts data into database
    contact_data.insert_one(ajax_data)

    #Returns data to ajax
    return jsonify({'Success it worked'})

Please include the full error traceback – Hymns For Disco Feb 08 '20 at 14:08 — Hymns For Disco, Feb 08 '20 at 14:08
Could you print out `type(request.data)`? – Dan Getz Feb 08 '20 at 14:30 — Dan Getz, Feb 08 '20 at 14:30

You should change this:

request.data.read()

into this:

request.data

request.data is already a string, there's no point "reading" it.

trying to answer the question in the comments. instead of ajax_data = json.load(request.data) you should use something like this:

try :
    ajax_data = json.loads(request.data)  # notice: loadS here
except :
    print( 'Invalid JSON data', request.data )

Hey thank you for your response. I just tried it ( ajax_data = json.load(request.data)) and I got AttributeError: 'bytes' object has no attribute 'read' still – kvothe Feb 08 '20 at 14:13
@kvothe you should have tried `loadS` with "S" on the end. (lowercase 's') – lenik Feb 08 '20 at 14:15
Ya I tired that too and got TypeError: Object of type set is not JSON serializable – kvothe Feb 08 '20 at 14:18
@kvothe well, print is out (`print request.data`) and see if it's JSON, then? – lenik Feb 08 '20 at 14:25
I am sorry I am very new to programming could you please explain in more detail what you are asking me to do. Once again thank you for your help!!!! – kvothe Feb 08 '20 at 14:29
@kvothe see the edited answer – lenik Feb 08 '20 at 14:31
I got this error raise TypeError(f'Object of type {o.__class__.__name__} ' TypeError: Object of type set is not JSON serializable. – kvothe Feb 08 '20 at 14:38
request.get_json() should be used instead – OneCricketeer Feb 08 '20 at 14:42
