POST data from Python script to Flask

Question

I am trying to send data from a python script to flask endpoint. I have tried many things but I don't understand where I am going wrong. Please let me know if you have a solution or any reference that can help me.

Thanks in advance

This is the Flask code which gets json data:

@app.route('/ramp-DynDB-DQ-PostTableItem', methods=['POST' , 'GET'])
def PostDQTableItem():
    data = request.get_json()
    print(data)

This is the Python Script that Posts data:

 import requests

newHeaders = {'Content-type': 'application/json', 'Accept': 'text/plain'}
response = requests.post('http://blabla:5000/ramp-DynDB-DQ-PostTableItem',
                        data={"Key": "key", "Path": "path"},
                        headers=newHeaders)

Status code:

correct me if I am wrong , I am guessing this is the JSON data={"Key": "key", "Path": "path"} — Rakesh Kumar

No, it's not. It's a regular Python dict. And requests will take that dict and transform it into the standard format for HTTP POSTs, which looks like this: Key=key&Path=path. You have two options: a) Change your client code so that it sends JSON. b) Change your server code so that it also accepts standard POST requests. — Tomalak

Can You give me example brother, I am okay to change both client or server code — Rakesh Kumar

There are many examples, have a look around. The standard format for HTTP POST requests is called application/x-www-form-urlencoded, the JSON format is called application/json. With these keywords you should find plenty of examples for both flask and requests. — Tomalak

Converting Dict to JSON format worked for me:

import requests, json

data = {"Key": "key", 
        "Path": "path"
        }

json_object = json.dumps(data, indent = 4)   
print(json_object) 
newHeaders = {'Content-type': 'application/json', 'Accept': 'text/plain'}
res = requests.get('http://blabla/ramp-DynDB-DQ-PostTableItem')
response = requests.post('http://blabla/ramp-DynDB-DQ-PostTableItem',
                        data=json_object,
                        headers=newHeaders)
print(response.text)

You don't need to do all that requests has a json attribute: requests.post('http://blahblah/etc', json=data) would do the same as the above code. requests.readthedocs.io/en/master/user/quickstart/…

I tried that Doobeh, for some reason it said json is not recognized
