How to get data value from webserver of ESP8266?

Hi friends, I’ve just created a webserver based on ESP8266 platform (connected to ssid and password of my home’s wifi network) to measure temperature like this:

Can anyone show me how can I display this value on openhab’s item? How can I config and setup in items, sitemaps,rules files?
Thanks in advance
Sincerely,

Use the HTTP binding.
