is there any api document for EasyIoT Server?

Is there any api document for EasyIoT Server?

i learn API just from example,it very useful,but i need some other query function, the API may like "url += "GET /Api/EasyIoT/Control/Module/Virtual/" + String(EIOT_NODE) + "/ControlLevel/" + String(value); "

Is there any api document for EasyIoT Serve ?

i run it in Raspberry PI II .

waitting for repond,thank you.

i used WireShark to grab the raspberry pi ip , found the API is :
GET /Api/EasyIoT/Events/RealTime.EventStream/?lastEventId=1.47894927500689E%2B15&r=107797914277611 HTTP/1.1\r\n

and then some other Authorization info

but i don't know how to get "lastEventId" and "r" like below ? if i want qurey last module value。

Request URI Query Parameter: lastEventId=1.47894927500689E%2B15
Request URI Query Parameter: r=107797914277611

and there is another problem, when i check module history value in chart ,it's just a line , just one value always, and when the value is update , last value can't show in chart.

i try to chmod the database file ,but the problem is still 。 how to solve it ?
