how to get HttpResponse key value and get the response from some url?

Question

I need to get a key value of HttpResponse from some URL and send the value again to the url to get some results through Restapi

resp = requests.get('https://someurl.io')
data = HttpResponse(resp)
return data

with this code i got a response like,

{"status":200,"result":{"postcode":"BN14 9GB","quality":1,"eastings":515087,"northings":105207,"country":"England","nhs_ha":"South East Coast","longitude":-0.36701,"latitude":50.834955,"european_electoral_region":"South East","primary_care_trust":"West Sussex","admin_ward":"Offington","ced":"Cissbury","ccg":"NHS Coastal West Sussex","nuts":"West Sussex (South West)","codes":{"admin_district":"E07000229","admin_county":"E10000032","admin_ward":"E05007703","parish":"E43000150","parliamentary_constituency":"E14000682","ccg":"E38000213","ced":"E58001617","nuts":"UKJ27"}}}

I have to send only the latitude and longitude value to some URL and get results. I would like to do this in rest api. I dont know how to get only latitude and longitude value and through the value how to get response from someurl.io.

You can obtain the dictionary of the result with data.json()['result'], and thus then construct a new dictionary. — willeM_ Van Onsem

You can obtain a Python dictionary with data.json(), and then do some processing to construct a new dictionary, like:

resp = requests.get('https://someurl.io')
resp_data = resp.json()['result']
result_dic = {
    'longitude': resp_data['longitude'],
    'latitude': resp_data['latitude']
}

# ...

You can for example return the dictionary as:

return JsonResponse(result_dic)

and this will thus contain a dictionary with two keys: 'longitude' and 'latitude'. You can of course pass other values as well.

but i can get values only this command return JsonResponse(result_dic['longitude'], safe=False) it doesnot work if i give return JsonResponse(result_dic['longitude'], result_dic['longitude'], safe=False) why??

@Divyaprabha: please don't return a non-dictionary as JsonResponse, there have been several hacks with this: haacked.com/archive/2008/11/20/… that is why safe=... is used here.

@Divyaprabha: no just JsonResponse(result_dic), don't make it harder than it is.

TypeError Exception Value: string indices must be integers got this error.. That's why I wrote like that.

@Divyaprabha: did you by any chance still use data = HttpResponse(resp)?
