Hello tangoer.
because JSON has not char data type, i want to execute DevVarCharArray command, how to set input value, [48,49,50]
or ["0","1","2"]
all failed
PUT hosts/localhost/devices/sys/tg_test/1/commands/DevVarCharArray
{
"host": "localhost:10000",
"device": "sys/tg_test/1",
"name": "DevVarCharArray",
"input": [48,49,50]
}
When write attribute(s), i want to pass new value in request’s body, but failed
PUT hosts/localhost/devices/sys/tg_test/1/attributes/long_spectrum/value"
# will set value to [], not [1,2,3,4]
{
"host": "localhost:10000",
"device": "sys/tg_test/1",
"name": "long_spectrum",
"value": [1,2,3,4]
}
thanks
Hi Jimmy,
As per version 2.1 DevVarCharArray is not supported.
Concerning long spectrum you should pass an argument as v
query param:
PUT .../devices/sys/tg_test/1/attributes/long_spectrum/value?v=[1,2,3]
OR in encoded way:
PUT .../devices/sys/tg_test/1/attributes/long_spectrum/value?v=%5B1%2C2%2C3%5D
Hope this helps

Thank you Ingvord
For write attributes, should pass an argument as v
query param. As from https://tango-rest-api.readthedocs.io/en/v1.1/device/#value have: argument can be passed in request’s body. so i get can pass an argument as request body
That’s true, you can pass arguments in body for multiple attributes reading/writing, e.g. https://tango-rest-api.readthedocs.io/en/v1.1/hosts/#attributes
For single device attributes query parameter v
is used
Cheers,
