hi,
That seems to be a bug.
The work around would be creating a rule with Chinese symbols in GUI, then requesting the rule via API and copying symbols.
Here is the result for your case
"eventCondition": "{\"caption\":\"GV-AS810-Join 測試 - Door 1 - Unlock Door\",\"description\":\"_door_opened\",\"eventTimestampUsec\":\"0\",\"eventType\":\"undefinedEvent\",\"metadata\":{\"allUsers\":true,\"level\":\"\"},\"omitDbLogging\":false,\"progress\":0,\"reasonCode\":\"none\"}",0 -
Hi,
Deeper investigation gave the following solution.
The Server expect latin-1 encoded string representing utf-8 encoded JSON.
That means, before being sent to the Server the JSON has to be
1. serialized
2. encoded to utf-8 byte array
3. byte array has to be decoded to latin-1 string
In python it look like this.
import json
import requests
# omitting authorization requests
event_condition = "{\"caption\":\"GV-AS810-Join測試 - Door 1 - Unlock Door\",\"description\":\"_door_opened\",\"eventTimestampUsec\":\"0\",\"eventType\":\"undefinedEvent\",\"inputPortId\":\"\",\"metadata\":{\"allUsers\":true,\"level\":\"\"},\"omitDbLogging\":false,\"progress\":0,\"reasonCode\":\"none\"}"
rule_json = {
"id": "{d36561c9-cb35-43fc-abaa-be8f9ffe875d}",
"eventType": "softwareTriggerEvent",
"eventResourceIds": [],
"eventCondition" : event_condition.encode("utf_8").decode("latin_1"),
"eventState": "undefined",
"actionType": "execHttpRequestAction",
"actionResourceIds": [],
"actionParams": "{\"allUsers\":false,\"authType\":\"authBasicAndDigest\",\"durationMs\":5000,\"forced\":true,\"fps\":10,\"httpMethod\":\"GET\",\"needConfirmation\":false,\"playToClient\":true,\"recordAfter\":0,\"recordBeforeMs\":1000,\"streamQuality\":\"highest\",\"url\":\"http: //192.168.0.228:80/ASWeb/WebService.srf?username=1&password=1&module=monitor&is_nx=1&action=DOOR_OPERATION&operation=UNLOCK_DOOR&dvg_id=0&ctrl_id=1&dr_id=0\",\"useSource\":false,\"gateData\":{\"device_type\":0,\"dvg_id\":0,\"dvg_name\":\"Default\",\"node_id\":1001,\"device_id\":1,\"gate_id\":0,\"io_type\":0,\"device_name\":\"GV-AS810-Join測試\",\"gate_name\":\"Door 1\",\"is_input\":0,\"is_elevator\":0,\"cam_idx\":0,\"nx_cams\":[\"67bb95bd-66dc-f753-c1ba-f399faf82e95\",\"01357f1b-0e0d-e85c-a0a7-e07b816cb748\"]}}",
"disabled": False,
"comment":"ASManager Software Trigger Event 測試",
"system":False
}
r = requests.post(API_URL,
data=json.dumps(rule_json),
headers={
'Authorization': f'Bearer {bearer_token}',
'Content-Type': 'application/json'

Hi,
Thanks for your reply.
Are there any plans to fix this bug in future versions?
If so, then I'll wait for it.
Otherwise I will implement UTF-8 encoding in my project.

Hi,
The bug has just been found. Though the bug report has been created, no plans so far.
My guess, it will be fixed in v6.1

I've corrected it. It's not just about UTF-8 encoding.

Andrey Terentyev,
I have solved this bug in my Javascript project.
ec2/saveEventRule:params.eventCondition) = unescape(encodeURI(params.eventCondition));
ec2/getEventRules:params.eventCondition = decodeURIComponent(escape(params.eventCondition));
Thx.0
