API - Writing new value into a register
Материал из WebHMI Wiki
To write a new value to the register, it is necessary to execute the PUT request for a URL of the form 'http://192.168.1.1/api/register-values/23' . Here 23 is the register ID for which you want to change the value.
In the request headers, you must pass the API key. For example:
X-WH-APIKEY: F3C74230818DA487BB2017CE5D0290F4DABCAFD7
Also, in the headers, you must specify the desired data exchange format. Currently, only the JSON format is supported.
Accept: application/json Content-Type: application/json
In the body of the request, you must pass a json object with a single property
"value":
{"value":"12"}
Example of writing a value of 15 to the register c ID = 5:
URL: http://192.168.1.1/api/register-values/5
Method: PUT
Headers:
Accept: application/json Content-Type: application/json Accept-Encoding: gzip, deflate, sdch X-WH-APIKEY: F3C74230818DA487BB2017CE5D0290F4DABCAFD7
Query body:
{"value":"15"}
If the request is valid then the API will return the HTTP code 200.
