How to Post Json Data With Python Requests

How to POST JSON data with Python Requests?

Starting with Requests version 2.4.2, you can use the json= parameter (which takes a dictionary) instead of data= (which takes a string) in the call:

>>> import requests
>>> r = requests.post('http://httpbin.org/post', json={"key": "value"})
>>> r.status_code
200
>>> r.json()
{'args': {},
 'data': '{"key": "value"}',
 'files': {},
 'form': {},
 'headers': {'Accept': '*/*',
             'Accept-Encoding': 'gzip, deflate',
             'Connection': 'close',
             'Content-Length': '16',
             'Content-Type': 'application/json',
             'Host': 'httpbin.org',
             'User-Agent': 'python-requests/2.4.3 CPython/3.4.0',
             'X-Request-Id': 'xx-xx-xx'},
 'json': {'key': 'value'},
 'origin': 'x.x.x.x',
 'url': 'http://httpbin.org/post'}

How to POST JSON with data payload and header with Python Requests?

Looks like you need to expand the payload to include more (all) of the parameters (including the cookies, specifically the ASP.NET_SessionId).

import requests

import warnings
warnings.filterwarnings("ignore")

term=24
amount=5000

url = 'https://simuladores.bancomontepio.pt/ITSCredit.External/Calculator/ITSCredit.Calculator.UI.External/gateway/Calculator/api/Calculator/Calculate?hash=-1359629931'

headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/81.0.4044.122 Safari/537.36',
'Accept-Language': 'pt-PT,pt;q=0.9,en-US;q=0.8,en;q=0.7',
'Cookie':'ASP.NET_SessionId=fhkyn1vn5knlw3uhdnh50nii;'}


payload = {
    "CCRDCalculateInput":{},
    "MultifunctionsCalculateInput":{},
    "Device":{
        "Browser":"chrome",
        "BrowserVersion":"96.0.4664.110",
        "Device":"Desktop",
        "Os":"windows",
        "OsVersion":"windows-10",
        "UserAgent":"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/96.0.4664.110 Safari/537.36"},
    "IsCustomer":'true',
    "Amount":amount,
    "Term":term,
    "ConditionCode":"26B1129900X-01-I-129900-F",
    "CreditDestinationCode":"129900",
    "ProductCode":"26B1129900X",
    "FinancedExpenses":'false',
    "FrequencyTrancheCode":'null',
    "GoalCode":"C006",
    "GoalDescription":"PROJETOS PESSOAIS",
    "FrequencyTypeCode":"M",
    "FamilyCode":"CP",
    "Proponents":[{
        "Position":'1',
        "Birthday":"1992-03-10T13:03:24.000Z",
        "State":'true',
        "EntityType":{
            "ID":'1',
            "CompanyID":'1',
            "Code":"P",
            "Description":"Proponente",
            "Value":'null',
            "ValueString":'null',
            "State":'true',
            "Imported":'null'},
        "ExpenseCodes":[
            "009"]}],
    "Counterparts":'0',
    "OptionalExpenses":[{
        "Code":"009",
        "Factor":'1'}],
    "ResidualValue":'0',
    "InterestOnly":'0',
    "Deferment":'0'}

jsonData = requests.post(url, headers=headers, json=payload, verify=False).json()
results = jsonData['Result']

mtic = results['MTIC']
installment = results['PeriodInstallment'][0]['Installment']
taeg = results['TAEG']
tan = results['PeriodInstallment'][0]['TAN']


print(f'Installment: {installment}\nTAEG: {taeg}\nTAN: {tan}\nMTIC: {mtic}')

Output:

Installment: 224.5
TAEG: 14.8
TAN: 7.0
MTIC: 5708.2

How to send file and json data with python requests library?

Thanks to @OlvinRoght I found the answer.

you can set data arguments to whatever data you have and files argument for files.

like this:

my_file = open(filename, 'rb')
file = {
        'upload': (
            os.path.basename(filename), my_file ,
            'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'
        )
    }
data = {
        'uuidKey': str(user_key),
        'agree-term': False,
        'is_tarh': is_incentive_traffic_zone,
        'description': ''
    }

result = requests.post("http://127.0.0.1:5000/schedule-payment", data=data, files=file)

Sending post request with both data and JSON parameters

requests.post(url, json=payload) is just a shortcut for requests.post(url, data=json.dumps(payload))

Note, the json parameter is ignored if either data or files is passed.

docs

So, no, it is not possible to pass both data and json parameters.
