python request iugu returns status 400

Question

I’m testing the api of yugu. to generate boletus payments and I’m having problems returning json because there is no error in Dictionary items that is sent to the API (in php it would be an array)

the code is as follows::

from flask import Flask, Response, jsonify
import requests
from requests.auth import HTTPBasicAuth
import json

app = Flask(__name__)

@app.route("/")

def index():
    dados = {
        'method':'bank_slip',
        'email':'[email protected]',
        'items[]':[
            {'description':'Item Um', 'quantity':1, 'price_cents': 100000},
            {'description':'Item Dois', 'quantity':1, 'price_cents': 200000}
        ]
    } 

url = 'https://api.iugu.com/v1/charge' 
user = '002f38a6d40b0275fc08aaac503a775b'
headers = {'content-type': 'application/json'}

r = requests.post(url, auth=HTTPBasicAuth(user, ''), headers = headers, params = json.dumps(dados))

return jsonify(
    resposta = [
        r.json(),
        {
            'status': r.status_code,
            'cabecalho': r.headers['Content-Type'],
            'params': dados,
            'text': r.content,
            'url': r.url
        }
    ])

app.debug = True
app.use_reloader=True
app.run()

The answer:

{
  "resposta": [
    {
      "errors": "token n\u00e3o \u00e9 v\u00e1lido"
    }, 
    {
      "cabecalho": "application/json; charset=utf-8", 
      "params": {
        "email": "[email protected]", 
        "items[]": [
          {
            "description": "Item Um", 
            "price_cents": 100000, 
            "quantity": 1
          }, 
          {
            "description": "Item Dois", 
            "price_cents": 200000, 
            "quantity": 1
          }
        ], 
        "method": "bank_slip"
      }, 
      "status": 400, 
      "text": "{\"errors\":\"token n\\u00e3o \\u00e9 v\\u00e1lido\"}", 
      "url": "https://api.iugu.com/v1/charge?%7B%22email%22:%20%[email protected]%22,%20%22items[]%22:%20[%7B%22price_cents%22:%20100000,%20%22description%22:%20%22Item%20Um%22,%20%22quantity%22:%201%7D,%20%7B%22price_cents%22:%20200000,%20%22description%22:%20%22Item%20Dois%22,%20%22quantity%22:%201%7D],%20%22method%22:%20%22bank_slip%22,%20%22format%22:%20%22json%22%7D"
    }
  ]
}

If I try to use as in the example of the site that looks like this:

'items[][description]':'Item Um', 
'items[][quantity]':'1', 
'items[][price_cents]':'100000', 

the answer returns correctly, but it is not possible to add more than one item because it only considers the second insertion. Is there another way to send data or am I doing something wrong?

Answer 1

Resolved issue

I got a tip from the yugu. to verify the data that is sent via Curl, is the postcatcher.in. There it was possible to create a session and direct the url of my application to the url that is in the brownser after starting on this site. With this it is possible to monitor in real time, in the body tab, whether the data was sent or not among other header observations and other information (I found it very cool)

With this site I saw that it was not sent or items or anything that I wanted it to be and it helped me to see that the requests line was wrong.

Instead of using params the right one was to use date.

It all worked out.
