Nested Dictionaries To Json For The Post Request Python

I am having trouble converting the payload data in the form of nested dictionaries to pass it as a data for the POST request using Python requests module. The form data is as below

Solution 1:

I had similar problem, frustrating but I solved it. Python requests do not work with nested json, they expect one layer json. It processes like form(application/x-www-form-urlencoded)

# Wrong
data = {'param1': {'a':[100, 200]},
        'param2': 'value2',
        'param3': False}

# You have to convert values into string:
data = {'param1': json.dumps({'a':[100, 200]}),
        'param2': 'value2',
        'param3': json.dumps(False)}

In your case:

import json
params = {
        'appkey': "936725A4-7D9A-11E5-81AC-86EC8D89CD5A"},
        'formdata':{
            'currency':'US',
            'dataview':'store_default',
            'distinct':'_distance, clientkey',
            'geolocs':{
                    'geoloc':[{
                            '0':{
                                    'address1':'',
                                    'addressline':'19128, PA',
                                    'city':'Philadelphia',
                                    'country':'US',
                                    'latitude':'40.0532987',
                                    'longitude':'-75.23040379999998',
                                    'postalcode':'19128',
                                    'province':'',
                                    'state':'PA'}}]
                    },
            'google_autocomplete':'true',
            'limit':'250',
            'nobf':'1',
            'searchradius':'15|25|50|100|250|350|450|550|650|750|850|950',
            'true':'1',
            'where':{'partner_reseller': {'eq':'1'}}}                    
          }
payload = {'request':  json.dumps(params) }

r = requests.post(url,data=payload) # important to keep payload as json!!!
result = r.text # or depends what the returnis..

Solution 2:

My suggestion is to use the JSON parameter and let requests both encode the object to JSON and let requests set the Content-Type header to application/json.

It's very possible that the web service assumes you're passing it XML, unless you specify that you're passing JSON, via setting the Content-Type to application/json. (It's also possible this web API really wants XML too, the docs for the service would tell you)

requests.post(url,json=payload,headers=header)
