background analysis

Familiar EasyNVR product of a small partner should know, EasyNVR mainly targeted project security types through RTSP / onvif protocol front-end high-definition network camera IPC, NVR and other access came in, and then the audio and video equipment side by acquisition, conversion, output RTMP , HLS, HTTP-Flv format live streaming, live full platform without plug-ins.

For dynamic website, real-time updates to the site, to obtain real-time information is an essential part through the interface. EasyNVR IPC can access other front-end device must be acquired in real time corresponding to real-time information to the IPC for display.

Here we describe the Ajax to get the data

In EasyNVR channel interface will be described:

• Operation: H5 list display;
• Interface: / api / v1 / getchannels

return:

• All equipment list information, online & offline channels (includes snapshot information)
• Channel name, channel number, channel snapshot, whether online channel

Message:

{
"EasyDarwin" : {
		"Body" : {
		"ChannelCount" : "2",
		"Channels" : [
				{
				"Channel" : 1,
				"Name" : "channel1",
				"Online" : 1,
				"SnapURL" : "/snap/1/2016-10-24/20161024125212.jpg"
				},
				{
				"Channel" : 2,
				"Name" : "channel2",
				"Online" : 0,
				"SnapURL" : ""
				}
		]
},
"Header" : {
"CSeq" : "1",
"ErrorNum" : "200",
"ErrorString" : "Success OK",
"MessageType" : "MSG_SC_SERVER_GET_CHANNELS_ACK",
"Version" : "1.0"
}
}
}

Ajax may be performed by the front end access interface to acquire data interfaces; the first observation of the type of data returned; operator returns the data analysis process; and display the returned data as objects traverse;

• Return data in the form of:
