如何在 Django 1.6 中使用 HTTP POST 请求接收 json 数据？

Question

I am learning Django 1.6.
I want to post some JSON using HTTP POST request and I am using Django for this task for learning.
I tried to use request.POST['data'] , request.raw_post_data , request.body but none are working for me.
my views.py is

import json
from django.http import StreamingHttpResponse
def main_page(request):
    if request.method=='POST':
            received_json_data=json.loads(request.POST['data'])
            #received_json_data=json.loads(request.body)
            return StreamingHttpResponse('it was post request: '+str(received_json_data))
    return StreamingHttpResponse('it was GET request')

I am posting JSON data using requests module.

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

r.text should print that message and posted data but I am not able to solve this simple problem. please tell me how to collect posted data in Django 1.6?

Answer 1

You're confusing form-encoded and JSON data here. request.POST['foo'] is for form-encoded data. You are posting raw JSON, so you should use request.body .

received_json_data=json.loads(request.body)

Answer 2

对于python3，您必须先解码主体：

received_json_data = json.loads(request.body.decode("utf-8"))

Answer 3

One way is to use ajax.

frontend (javascript):-

var data_to_send = {}; //push 'values to send' into this. $.ajax({
      ..... //other ajax attributes
      data: {'val': JSON.stringify(data_to_send)},
      ..... //other ajax attributes });

backend (views.py):-

def RecieveData(request):
      data = json.loads(request.POST.get('data')) //contains the front end variable 'data_to_send'
      ..... //code as per requirements

Answer 4

Create a form with data as field of type CharField or TextField and validate the passed data. Similar SO Question
