AttributeError: 'tuple' object 在 Postman 中使用 POST 请求时没有属性 'get'

Question

I'm trying to use request.get_json() to add nodes from JSON data to a set.

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

def connect_node():
    json = request.get_json()
    nodes = json.get('nodes')              
    if nodes is None:
        return "No node", 400 

The snapshot of the Postman POST request

The error I'm getting in Spyder(Python 3.9):

line 178, in connect_node
nodes = json.get(nodes)
AttributeError: 'tuple' object has no attribute 'get' 

Answer 1

I'm assuming your going though the udemy blockchain course, turns out its just a problem with the postman check this out Flask app request.get_json() return (Ellipsis, Ellipsis) instead of json

Answer 2

If you are using python 3.9 and getting this error then Build a virtual environment in anaconda with python 3.6 and use this python interpreter for all Spyder consoles. It worked in my case.
