How to use Here Api to get Max speed limit of road using latitude and longitude in python environment

We are new to Here Api,
Our team is working on one transportation project in which we required to get max speed limit of road using vehicle (latitude ,longitude).
From last few days we are trying to figure out which api should we use in HereApi to achieve what we want.

Regarding this documentation of HERE Route Matching 8: https://developer.here.com/documentation/route-matching/api-reference.html
Send please POST request like:

With in body:
LATITUDE,LONGITUDE
37.4201866,15.049515

An apikey and coordinate you specify your own for sure.
About all layers attributes you can see this example: https://demo.support.here.com/pde/maps?url_root=pde.api.here.com
In Python you should use normal POST request using some http libraries developed for Python:

replace nested document array mongodb with python

i have this document in mongodb
{
"_id": {
"$oid": "62644af0368cb0a46d7c2a95"
},
"insertionData": "23/04/2022 19:50:50",
"ipfsMetadata": {
"Name": "data.json",
"Hash": "Qmb3FWgyJHzJA7WCBX1phgkV93GiEQ9UDWUYffDqUCbe7E",
"Size": "431"
},
"metadata": {
"sessionDate": "20220415 17:42:55",
"dataSender": "user345",
"data": {
"height": "180",
"weight": "80"
},
"addtionalInformation": [
{
"name": "poolsize",
"value": "30m"
},
{
"name": "swimStyle",
"value": "mariposa"
},
{
"name": "modality",
"value": "swim"
},
{
"name": "gender-title",
"value": "schoolA"
}
]
},
"fileId": {
"$numberLong": "4"
}
}
I want to update nested array document, for instance the name with gender-tittle. This have value schoolA and i want to change to adult like the body. I give the parameter number of fileId in the post request and in body i pass this
post request : localhost/sessionUpdate/4
and body:
{
"name": "gender-title",
"value": "adultos"
}
flask
#app.route('/sessionUpdate/<string:a>', methods=['PUT'])
def sessionUpdate(a):
datas=request.json
r=str(datas['name'])
r2=str(datas['value'])
print(r,r2)
r3=collection.update_one({'fileId':a, 'metadata.addtionalInformation':r}, {'$set':{'metadata.addtionalInformation.$.value':r2}})
return str(r3),200
i'm getting the 200 but the document don't update with the new value.

As you are using positional operator $ to work with your array, make sure your select query is targeting array element. You can see in below query that it is targeting metadata.addtionalInformation array with the condition that name: "gender-title"
db.collection.update({
"fileId": 4,
"metadata.addtionalInformation.name": "gender-title"
},
{
"$set": {
"metadata.addtionalInformation.$.value": "junior"
}
})
Here is the Mongo playground for your reference.

API.ai Actions on Google API Version 2: Failed to parse JSON response string with 'INVALID_ARGUMENT' error: ": Cannot find field."

I am using python to create webhook for Assistat app. I am able to ask user for location permission, but as soon as user gives consent, I receive following error
UnparseableJsonResponse

API.ai Intent settings

The most likely reason you're not getting any hits on your webhook is that you don't have an intent registered to get the reply.
You can do this by creating an Intent with the Event set to actions_intent_PERMISSION.

How to parse JSON in a Django View

I post some JSON to a view. I want to now parse the data and add it to my database.
I need to get the properties name and theme and iterate over the array pages. My JSON is as follows:
{
"name": "xaAX",
"logo": "",
"theme": "b",
"fullSiteLink": "http://www.hello.com",
"pages": [
{
"id": "1364484811734",
"name": "Page Name",
"type": "basic",
"components": {
"img": "",
"text": ""
}
},
{
"name": "Twitter",
"type": "twitter",
"components": {
"twitter": {
"twitter-username": "zzzz"
}
}
}
]
}
Here is what I have so far:
def smartpage_create_ajax(request):
if request.POST:
# get stuff and loop over each page?
return HttpResponse('done')

python provides json to encode/decode json
import json
json_dict = json.loads(request.POST['your_json_data'])
json_dict['pages']
[
{
"id": "1364484811734",
"name": "Page Name",
"type": "basic",
"components": {
"img": "",
"text": ""
}
},
{
"name": "Twitter",
"type": "twitter",
"components": {
"twitter": {
"twitter-username": "zzzz"
}
}
},
}
]

Check whether the JSON (object property exists) & print it as unicode decoded

I get the following data from the Instagram API, I m trying to get the text property from the caption using the following code:
data = simplejson.load(info) # info is retrieved using the urllib2
for post in data['data']:
if post['caption'] is not "null":
try:
post['caption']['text']
except NameError:
post['caption']['text'] = 0
if post['caption']['text'] is not 0:
print post['caption']['text']
But I keep getting the TypeError: 'NoneType' object has no attribute '__getitem__' error + UnicodeEncodeError: 'charmap' codec can't encode characters in position 0-5: cha
racter maps to <undefined> error while printing the unicode strings
Here is the JSON data that is retrieved and stored in info

You don't need the intricate tests on wether 'text' is present for the post caption.
This code works well with the JSON string you posted:
for post in data['data']:
if post.get('caption'):
print post['caption'].get('text', 0)
Furthermore, you could be more defensive and refer to data.get('data', []) when starting the loop in case Instagram sends you empty JSON.

Basically when json loads and deserializes your object, null in JSON will become None in python.
So your line of:
if post['caption'] is not 'null':
Should become:
if post['caption']:
