Python querydict to json

Converting request body to json Django Python

In Python 2, json.loads will accept a unicode string or a byte sting, so the decode step is not necessary.,The request body, request.body, is a byte string. In Python 3.0 to 3.5.x, json.loads() will only accept a unicode string, so you must decode request.body before passing it to json.loads().,The problem is how do I get the body of the request in a string format?,How do I retrieve the body of the request as a string, with the correct encoding applied?

The request body, request.body , is a byte string. In Python 3.0 to 3.5.x, json.loads() will only accept a unicode string, so you must decode request.body before passing it to json.loads() .

body_unicode = request.body.decode('utf-8') body_data = json.loads(body_unicode) 

Answer by Devon Travis

CONTENT_LENGTH – The length of the request body (as a string).,CONTENT_TYPE – The MIME type of the request body.,A string representing the MIME type of the request, parsed from the CONTENT_TYPE header.,SERVER_PORT – The port of the server (as a string).

if request.method == 'GET': do_something() elif request.method == 'POST': do_something_else()

In Python 3.0 to Python 3.5.x, json.loads() will only accept a unicode string, so you must decode request.body (which is a byte string) before passing it to json.loads().,In Python 3.6, json.loads() accepts bytes or bytearrays. Therefore you shouldn’t need to decode request.body (assuming it’s encoded in UTF-8, UTF-16 or UTF-32).,Of course, nothing is being printed out, but when I print request.body I get this:,In Django I have a view that accepts this request as a parameter and just for my testing purposes, should print request.body[«content»] to the console.

It is being sent in JSON format, and looking at the Network tab in Dev Tools shows this as the request payload:

Of course, nothing is being printed out, but when I print request.body I get this:

Convert the corresponding types (if needed).,With just that Python type declaration, Django Ninja will:,Read the body of the request as JSON.,To declare a request body, you need to use Django Ninja Schema.

from ninja import Schema class Item(Schema): name: str description: str = None price: float quantity: int @api.post("/items") def create(request, item: Item): return item 

Answer by Aries Gibbs

Since the body is not sent with this post request, the value of attributes request.POST, request.body and request.FILES is empty.,In this format, the body is not sent in the post request.,When sending a post request from the postman, we select the «form-data» body type. Put the parameter name and values in KEY and VALUE columns.,Accessing request in view.py file:

Equivalent CURL request code:

curl --location --request POST 'localhost:8000/post-example/form-data/' \ --form 'name=pythoncircle' \ --form 'url=https://www.pythoncircle.com'

Accessing request in view.py file:

@csrf_exemptdef post_example_form_data(request): print('POST', request.POST) return render(request, 'hw/home.html', <>)

The output of print statements:

post_data = request.POST.copy() name = post_data.get("name")

curl --location --request POST 'localhost:8000/post-example/raw/' \ --header 'Content-Type: application/json' \ --data-raw '< "name": "pythoncircle", "url": "https://www.pythoncircle.com" >'

@csrf_exemptdef post_example_raw(request): print('POST', request.POST) print('BODY', request.body) print('JSON', json.loads(request.body.decode('utf-8'))) return render(request, 'hw/home.html', <>)

curl --location --request POST 'localhost:8000/post-example/form-urlencoded/' \ --header 'Content-Type: application/x-www-form-urlencoded' \ --data-urlencode 'name=pythoncircle' \ --data-urlencode 'name_spaced=python circle' \ --data-urlencode 'url=https://www.pythoncircle.com'

@csrf_exemptdef post_example_form_urlencoded(request): print('POST', request.POST) print('BODY', request.body) print(parse_qs(request.body.decode('utf-8'))) return render(request, 'hw/home.html', <>)

POST > BODY b'name=pythoncircle&name_spaced=python%20circle&url=https%3A%2F%2Fwww.pythoncircle.com' 

helloworld next line this is third line

curl --location --request POST 'localhost:8000/post-example/binary/' \ --header 'Content-Type: text/plain' \ --data-binary '@/home/rana/helloworld.txt'

@csrf_exemptdef post_example_binary(request): print('POST', request.POST) print('BODY', request.body) return render(request, 'hw/home.html', <>)

POST > BODY b'helloworld\nnext line\nthis is third line\n' 

curl --location --request POST 'localhost:8000/post-example/file-upload/' \ --form 'file=@/home/rana/helloworld.txt' \ --form 'name=pythoncircle'

@csrf_exemptdef post_example_file_upload(request): print('POST', request.POST) print('FILES', request.FILES) return render(request, 'hw/home.html', <>)

Equivalent CURL request code:

curl --location --request POST 'localhost:8000/post-example/none/'

Accessing request in view.py file:

@csrf_exemptdef post_example_none(request): print('POST', request.POST) print('BODY', request.body) print('FILES', request.FILES) return render(request, 'hw/home.html', <>)

Convert the corresponding types (if needed).,With just that Python type declaration, FastAPI will:,Read the body of the request as JSON.,If the parameter is declared to be of the type of a Pydantic model, it will be interpreted as a request body.

from typing import Optional from fastapi import FastAPI from pydantic import BaseModel class Item(BaseModel): name: str description: Optional[str] = None price: float tax: Optional[float] = None app = FastAPI() @app.post("/items/") async def create_item(item: Item): return item

Python: Query Dict to JSON

QueryDict class is a subclass of regular Python dictionary, except that it handles multiple values for a same key (see MultiValueDict implementation).

If you want to dump it to a string, just use json.dumps() :

There is also a relevant dict() method:

QueryDict.dict()

Returns dict representation of QueryDict.

I am using Python 2.7.13 and Django 1.11.2.You can get your data in a dictionary, so that you could access those data by using their related keys.

data = json.loads(request.GET.dict().keys()[0])

A block of code inside the function that I used to get the data. Output is also available at bottom. This will show the value of parts of the above statement.

But here I am using POST in place of GET as we are are posting data to the server.

So the above 1 line code is sufficient to get data as a dictionary in your case.

import json# request.POST print "request.POST hljs-built_in">print type(request.POST),"\n"# DICTIONARYprint "request.POST.dict() hljs-built_in">dict()print type(request.POST.dict()), "\n"# LIST ALL KEYS(here is only 1)print "request.POST.dict().keys() hljs-built_in">dict().keys()print type(request.POST.dict().keys()), "\n"# UNICODEprint "request.POST.dict().keys()[0] hljs-built_in">dict().keys()[0]print type(request.POST.dict().keys()[0]), "\n"# GETTING THE ORIGINAL DATA(as Dictionary)data = json.loads(request.POST.dict().keys()[0]) # PRINTING DATA AND IT'S TYPEprint "json.loads(request.POST.dict().keys()[0]): ", dataprint type(data), "\n"# ITERATING OVER ITEMS in data dictionaryfor key, value in data.iteritems(): print key, value

Solution 2

from django.http import QueryDict # serialize request.session["last_get_request"] = request.GET.urlencode() # deserialize last_get_request = QueryDict(request.session["last_get_request"]) 

Solution 3

If you want to handle multi values, you can do the following:

or use join for compactness:

or check if this is multi value, and only then show as list

 json.dumps( 1 else d[k]) for k in d.keys()>)
