In my flask project, there is a route:
def request_parse(req_data):
if req_data.method == 'POST':
data = req_data.json
elif req_data.method == 'GET':
data = req_data.args
return data
#app.route('/api/d/u', methods=['POST'])
def update(): # name, domain_list, pem_key, pem_cert, origin_ips
data = request_parse(request)
name = data.get('name')
domain_list = data.get('domain_list')
pem_key = data.get('pem_key')
pem_cert = data.get('pem_cert')
origin_ips = data.get('origin_ips')
in Postman I request it like this:
I use postman request the api:
you see it is POST method, and in my project debug, I found the request data is in form,not in json.
I also tried form-data and x-www-form-urlencoded format, all are in form.
why postman POST method do not provide params to request.json? and is it possible to provide params in request.json?
If you want to send it as JSON, change from x-www-form-urlencoded to raw and you should see a drop down for Text, JSON, HTML. You can then select JSON

Let's say we have a simple Django view:
def my_view(request):
content = request.body
# some actions with content varible
response = HttpResponse('<h1>It work!</h1>')
And a simple api client, let's say based on the requests library, sending malformed Django view data:
headers = dict()
headers['Accept'] = '*/*'
headers['Content-Length'] = '13409'
headers['Content-Type'] = 'application/x-compressed'
headers['Expect'] = '100-continue'
headers['Host'] = '127.0.0.1:8000'
headers['User-Agent'] = 'Api client'
headers['content-encoding'] = 'gzip'
url = 'http://127.0.0.1:8000/api'
request_body = ''
r = requests.post(
url,
data=request_body,
headers=headers
)
As you can see, request_body contains an empty string, but the Content-Length header stores the value 13409. When such a request arrives, Django hangs on the line reading request.body. No exceptions occur. How to solve this problem? I cannot influence the client, so the only thing I can do is rewrite the Django view. Django version 3.2.15 is used.
I'm writing a django application. I am trying to call my django rest framework from outside, and expecting an answer.
I use requests to send some data to a function in the DRF like this:
j=[i.json() for i in AttachmentType.objects.annotate(text_len=Length('terms')).filter(text_len__gt=1)]
j = json.dumps(j)
url = settings.WEBSERVICE_URL + '/api/v1/inference'
headers = {
'Content-Disposition': f'attachment; filename={file_name}',
'callback': 'http://localhost',
'type':j,
'x-api-key': settings.WEBSERVICE_API_KEY
}
data = {
'type':j
}
files = {
'file':file
}
response = requests.post(
url,
headers=headers,
files=files,
json=data,
)
In the DRF, i use the request object to get the data.
class InferenceView(APIView):
"""
From a pdf file, extract infos and return it
"""
permission_classes = [HasAPIKey]
def post(self, request):
print("REQUEST FILE",request.FILES)
print("REQUEST DATA",request.data)
callback = request.headers.get('callback', None)
# check correctness of callback
msg, ok = check_callback(callback)
if not ok: # if not ok return bad request
return build_json_response(msg, 400)
# get zip file
zip_file = request.FILES.get('file', None)
parsed = json.loads(request.data.get('type', None).replace("'","\""))
The problem is that the data in the DRF are not received correctly. Whatever I send from the requests.post is not received.
I am sending a file and a JSON together. The file somehow is received, but other data are not.
If I try to do something like
request.data.update({"type":j})
in the DRF, the JSON is correctly added to the data, so it is not a problem with the JSON I'm trying to send itself.
Another thing, request.body shows that the JSON is somehow present in the body, but request.data can't find it.
I don't want to use request.body directly because I can't understand why it is present in the body but not visible with request.data.
In this line
response = requests.post(
url,
headers=headers,
files=files,
json=data,
)
replace json=data with data=data
like this:
response = requests.post(
url,
headers=headers,
files=files,
data=data,
)
I am trying to make request to Clash of Clan Api and after requesting the right data it returns 200 ok & if i search wrong data it returns 404 not found. How to flash message after the data is not found according to the HTTP response from the API?
my views in flask
#app.route('/player', methods=['GET', 'POST'])
def player():
headers = header
url = ('https://api.clashofclans.com/v1/players/{}')
query = request.form.get('search')
player_id = urllib.parse.quote(query)
stats = requests.get(url.format(player_id), headers=headers).json()
return render_template('player.html', stats=stats, data=stats['achievements'])
stats = requests.get(url.format(player_id), headers=headers).json()
Here, you just take the JSON from the body and discard a bunch of useful data. Instead,
response = requests.get(url.format(player_id), headers=headers)
stats = response.json()
status_code = response.status_code
success = response.ok
# ...
You can see all the things you can get from the Response object in API documentation.
I am trying to post some data from Dojo to Django application. I use postData to post the data to the server
here is the code snippet
var csrftokenval = dojo.cookie('csrftoken');
var selectedmoid1 = tree.getSelectedItemId();
var loadURL = '/calerts/';
dojo.rawXhrPost({
url : loadURL,
headers : {'X-CSRFToken':csrftokenval},
postData: dojo.toJson({'selectedmoid':selectedmoid1,'previousval':previousVal}),
handleAs: "text",
load : function(data, ioArgs){
dojo.byId('content-main').innerHTML = data;
},
error : function(data, ioArgs){
}
});
In the Django views i get the data as
def calerts(request):
user = request.user
compId = int(request.session.get('USERCOMPANY_ID','-1'))
listCount = 25
print '0000000000000000000000000000000 ',request.POST
print 'post dictionary ::: ',request.POST.dict()
I know to get the dict value from querydict using dict() method however in my case the print is
post dictionary ::: {u'{"selectedmoid":"4","previousval":"4"}': u''}
i dont undersand where that final u'' comes from. Also i would like to retrieve the values of selectedmoid and previousval
Your sending the data as a raw JSON post, not a form-encoded one. So you should access request.body, not request.POST, and decode the JSON from there.
In my view function, I'd like to return a json object (data1) and some text/html (form). Is this possible?
Here is part of my views.py:
if request.is_ajax() and request.method == 'POST':
...
if form.is_valid():
answer = form.cleaned_data['answer'] # Answer extracted from form is also a string
a1 = ques1.correct_answer
if a1 == answer:
test1 = question_list.get(id=nextid)
form = AnswerForm(test1)
ques1 = question_list.filter(id=nextid) # Filter next question as <qs>
data1 = serializers.serialize("json",ques1) # Json-ize
# ********EDITED HERE **********
variables1 = Context({
'form' : form,
'q1' : data1,
})
#response = HttpResponse()
#response['data1'] = response.write(data1)
#response['form'] = response.write(form)
if nextid <= qsnlen:
return HttpResponse(variables1, mimetype="application/json")
#return HttpResponse(response)
else:
...
I'd like to send back both the form html and the ques1 json object. How can I do this? Thanks in advance.
Just put both pieces of data in a JSON container, one key with the form data and one with the HTML as a rendered string. In the browser, you can just pull both keys out & do your thing.
In your view:
form_json_data = get_form_json_data()
rendered_html = get_the_html()
return HttpResponse(json.dumps({
"formdata": form_json,
"html": rendered_html}),
content_type="application/json")
In js:
$.post(foo, postdata, function(data){
var formdata = data.formdata
var html = data.html;
$(".html-target").replaceWith(html);
do_whatever(formdata);
})
Use JsonResponse
from django.http import JsonResponse
response_data = {put your data into a dict}
return JsonResponse(response_data, status=201)
To do this with one response; you need to send the JSON as a plain text in the context of your template response (HTML).
If you need to send JSON as as a separate JSON object, with its own mime type, then you need to write two views; one that sends back the JSON as application/json and the other that sends back the form (HTML).
EDIT:
You are not returning JSON objects, but you are turning a dictionary that has two items of two different types. As I explained in the comments, in one request/response cycle; you can only return one response which has a specific mime type that is based on the content and how you want the browser to handle it. Most of the time the content type is 'text/html'.
In your scenario, if you want to return both the HTML (which is your form), and the JSON response (which is a string), you need to return HTML.
If you want to return JSON to Jquery as a JSON object; you need to detect the request type. In your front end (the templates), you will initiate two requests - one from the browser, which will return back the form. The other from jQuery, which will return the appropriate JSON object.
Here is a possible approach to this:
def foo(request):
if request.is_ajax():
ctx = dict()
ctx['hello'] = 'world'
return HttpResponse(json.dumps(ctx),content_type='application/json')
else:
return HttpResponse('hello world')
