Add multipart for Python

[Nishant Kumar]

Describe the bug/problem
the code generated for python(both) is not correct for multipart having type json and text

Steps to Reproduce the bug/problem
paste a api link
click on view code
select any python request
choose formdata
the code that will appear is:

import requests
import mimetypes
from codecs import encode

url = 'http://nishant'

def build_data_list(fields):
    dataList = []
    for field in fields:
        name = field.get('name', '')
        value = field.get('value', '')
        type_ = field.get('type', 'text')

        dataList.append(encode('--20a87120-372b-1f03-87bb-d71ea3913925'))
        if type_ == 'text':
            dataList.append(encode(f'Content-Disposition: form-data; name="{name}"'))
            dataList.append(encode('Content-Type: text/plain'))
            dataList.append(encode(''))
            dataList.append(encode(value))
        elif type_ == 'file':
            dataList.append(encode(f'Content-Disposition: form-data; name="{name}"; filename="{value}"'))
            dataList.append(encode(f'Content-Type: {mimetypes.guess_type(value)[0] or "application/octet-stream"}'))
            dataList.append(encode(''))
            dataList.append(open(value, 'rb').read())
    dataList.append(encode('--20a87120-372b-1f03-87bb-d71ea3913925--'))
    dataList.append(encode(''))
    return dataList

dataList = build_data_list([{"name":"Nishant","value":"","type":"text"}])
payload = b'\r\n'.join(dataList)
response = requests.post(url, data=payload, json=json.loads(payload), headers=headers)

print('Status Code:', response.status_code)
print('Response Body:', response.text)

Expected behavior

import requests
import mimetypes
import json  # Added import for the json module

url = 'http://nishant'

def build_data_list(fields):
    dataList = []
    for field in fields:
        name = field.get('name', '')
        value = field.get('value', '')
        type_ = field.get('type', 'text')

        dataList.append(encode('--a4902730-3203-1f03-87bb-d71ea3913925'))  # Adjust boundary string
        if type_ == 'text':
            dataList.append(encode(f'Content-Disposition: form-data; name="{name}"'))
            dataList.append(encode('Content-Type: text/plain'))
            dataList.append(encode(''))
            dataList.append(encode(value))
        elif type_ == 'file':
            dataList.append(encode(f'Content-Disposition: form-data; name="{name}"; filename="{value}"'))
            dataList.append(encode(f'Content-Type: {mimetypes.guess_type(value)[0] or "application/octet-stream"}'))
            dataList.append(encode(''))
            dataList.append(open(value, 'rb').read())
    dataList.append(encode('--a4902730-3203-1f03-87bb-d71ea3913925--'))
    dataList.append(encode(''))
    return dataList

dataList = build_data_list([{"name":"asfacs","value":"acsacac","type":"text"}])
payload = b'\r\n'.join(dataList)
response = requests.post(url, data=payload, headers=headers)

print('Status Code:', response.status_code)
print('Response Body:', response.text)

here i have used arbitrary headers and api request and input json and text data for simplification only

@nikkivirtuoso You need to specify within code blocks what is the generated code and what is the expected code.

[Ankit Mahato]

@nikkivirtuoso why have you closed the issue?

[Nishant Kumar]

@animator In most cases, payloads are not sent as JSON unless explicitly requested by the API. The choice of payload format depends on the requirements specified by the API endpoint.

response = requests.post(url, data=payload, json=json.loads(payload), headers=headers)

[Nishant Kumar]

we can remove the json right ?

response = requests.post(url, data=payload, headers=headers)

[Ankit Mahato]

No. Python library supports this feature which is very useful and we want to provide users with generated code which is as natural as possible and which uses the full capabilities of the library.

[Nishant Kumar]

Now I am left with the file handling part, there is no file handling done in the code @animator

[Nishant Kumar]

there is one line missing for file handling part:

with open(value, 'rb') as f:
                file_content = f.read()

in the code

The issue has been resolved in the main branch.
