python - How to send data from python client to Django web server?

问题描述

I'd like python3 program to send JSON data to Django web server and print them on web page. This is what I have in Views.py:

def receive_json(request):
    if request.method == 'POST':
        received_data = json.loads(request.body.decode("utf-8"))
        return StreamingHttpResponse('it was post request: ' + str(received_data))
    return StreamingHttpResponse('it was get request')

And the python code:

import requests
import json
url = "http://127.0.0.1:8000/"
data = {"data": [{'key1':'val1'}, {'key2':'val2'}]}
headers = {'content-type':'application/json'}
r = requests.post(url, data=json.dumps(data), headers=headers)
r.text

However, it shows this message:

Forbidden (CSRF cookie not set.): /
[28/May/2021 16:51:31] "POST / HTTP/1.1" 403 2864

解决方案

import requests
import json
url = "http://127.0.0.1:8000/"
data = {"data": [{'key1':'val1'}, {'key2':'val2'}]}
headers = {'content-type':'application/json','Cookie':'csrftoken=axXsa39e5hq8gqlTjJFHAbUWtg2FQgnSd3cxxkx9khatqgersthtSryDxtF0cVCk'}
r = requests.post(url, data=json.dumps(data), headers=headers)
r.text

我认为这些可以通过添加 Cookie 来工作，但如果你通过这些方式在 receive_json 函数中使用 @csrf_exempt 装饰器会更好

from django.views.decorators.csrf import csrf_exempt
@csrf_exempt
def receive_json(request):
    if request.method == 'POST':
        received_data = json.loads(request.body.decode("utf-8"))
        return StreamingHttpResponse('it was post request: ' + str(received_data))
    return StreamingHttpResponse('it was get request')
