Description
Hello,
I'm wondering if it's possible to exclude a specific key in a filter rather than explicitly including all of the others.
For context, I have a JSON response I'm trying to parse that has a large array of strings I don't need. I'd like to keep the other ~15 keys, but it's a pain to keep track of every other key and mark each of those keys explicitly as "true" in the filter rather than marking one key as "false".
Here's a minimal sample of the JSON data:
{
"data": [
{
"id": "123456789",
"name": "John",
"started_at": "2021-08-12T19:54:18Z",
"language": "en",
"tag_ids": [
"ffb3744956f39b69bafd777c75efe3d3",
"dbbc7932c63c7a3776a7bc0c6f7696f1",
"cbc69d36b95b3d083fa78707bf4d67df",
"a3d0a2b834bda602fdd962f0f84c6210",
"26677562c8d68ce512f0ddc4d8390c69",
"dc816b81f3c4524a42838698859efbb6",
"f145b3b9d0567f41e658aa19d1c3fc65",
"2f173d6ef410aa016a40ffba3b11bf88",
"6f389ef6e9c811144b5efc63abbf83c9",
"fa4bb4e69607560b6007710f175dd302"
]
}
]
}And here's my current filter, using a wildcard:
{
"data": [
{
"*": true,
"tag_ids": false
}
]
}
The Assistant successfully filters out the "tag_ids" key, but the library on platform does not. I did not find any documentation using "false" values, so my guess is that this is not currently a supported feature.
I'm testing an ESP8266 (Wemos D1 Mini Lite) using Arduino 1.8.13. Here's the current C++ code:
StaticJsonDocument<96> filter;
filter["data"][0]["*"] = true;
filter["data"][0]["tag_ids"] = false;
StaticJsonDocument<2000> doc;
deserializeJson(doc, json, DeserializationOption::Filter(filter));Thanks for any advice!
