global device
global parameters
global interval
global data
headers = {
'authorization': "Bearer X...............",
}
devices_url = "http://127.0.0.1:8000/stations/list"
devices_params = {
'id': device
}
devices = requests.request("GET", devices_url, headers=headers, params=devices_params)
response = HttpResponse()
response['Content-Disposition'] = 'attachment; filename=Average Data.pdf'
elements = []
company_name = Paragraph(devices.json()[0]['site'], header_style)
elements.append(company_name)
report_data = Paragraph("Date: " + fromDate + " to " + toDate + " Station: " + devices.json()[0]['station'], title_style)
elements.append(report_data)
styles = getSampleStyleSheet()
styleN = styles['Normal']
styleN.wordWrap = 'CJK'
file_data = []
header = []
header.append("Timestamp")
header.append("Station")
for parameter in parameters:
header.append(parameter)
file_data.append(header)
data2 = [[Paragraph(cell, styleN) for cell in row] for row in file_data]
width = (PAGE_WIDTH-50) / len(header)
table_header = Table(data2, colWidths=width, style=table_header_style)
elements.append(table_header)
table_data = []
for key, values in data.items():
raw_data = []
raw_data.append(str(key))
raw_data.append(devices.json()[0]['station'])
for value in values:
raw_data.append(str(value))
table_data.append(raw_data)

elements.append(tableRaw)
doc.title = "Average Data"
meta_data = request.META.get('HTTP_X_FORWARDED_FOR')
if meta_data:

Answer 1

When you use requests for post in your case, you need pass data instead of params
It should be :
audit_obj=requests.post(audit_url, headers=headers, data=audit_parms)
Technically, when you do requests.post(url=your_url, params=your_params), the url will be like https://localhost?key=value with key value in params dictionary.

Answer 2

You should take a look at djangorestframework
https://www.django-rest-framework.org/tutorial/2-requests-and-responses/
This is the recommended way to write APIs with django.
