Error using API with Post

Frappe Framework
#1

Hello,

Trying to use API to send a record, using POST, and I got these error:

URL: http://localhost:8000/api/resource/Cidade
It’s correct, because if I run this url, I get all record from my database…

Using this:

JSON:

{"data":[
    {"descricao":"ALTO ALEGRE DOS PARECIS","id_conflex":10}
    ]
}

Debugging I saw this:

The json value isn’t in correct position? I think the correct is on form_dict.data not in form_dict

#2

Try checking with a standard DocType like ToDo

#3

@fellipeh
I hope this will help you

data = {
   "descricao": "ALTO ALEGRE DOS PARECIS",
   "id_conflex": 10
} 

url = "http://localhost:8000/api/resource/Cidade"

res = requests.post(url= url, data='data='+json.dumps(data), headers={'Content-type': 'application/json'})

@saurabh6790

same error here, any other idea?

@rmehta

Same error using ToDo… I use in these way:

 1 import json
  2 import requests
  3 data = {
  4        "description": "ALTO ALEGRE DOS PARECIS",
  5
  6 }
  7
  8 url = "http://localhost:8000/api/resource/ToDo"
  9
 10 res = requests.post(url= url, data='data='+json.dumps(data), headers={'Content-type': 'application/json'})

Show me these:

@fellipeh use this:

data = {
   "descricao": "ALTO ALEGRE DOS PARECIS",
   "id_conflex": 10
} 

url = "http://localhost:8000/api/resource/Cidade"

res = requests.post(url= url, data={"data": json.dumps(data)}, headers={'Content-type': 'application/json'})
#6

Same error.

I try using frappe_client, and works!

But if I try to using Delphi, or other POST app, like postman… doesn’t work.

I need to work with delphi, any tips?

#7

I found a solution.

I need to pass data, as Parameter…

on Delphi use this:

RestRequest.AddParameter('data', JSON);

Do not use RestRequest.Params!!!

Cheers
