In this embodiment, during registration, the intranet device may initiate a request to the centralized control device three times, specifically, the first request is used to obtain a cookie value of the centralized control device, and in a specific embodiment, the request format is as follows:
the request format is as follows:
URL www.abt.com (centralized control equipment URL or IP, varying depending on the configuration)
URL/v 1/useruth (fixed)
Type:GET
Body, the equipment must be carried, the centralized control equipment can check and judge whether to need to respond or not, and direct response can not be checked.
The data format of the first request is a json format, which is specifically as follows:
{
string 128,// access password, base64 encoding and decoding ginName are needed, string 128,// branch name, namely equipment name, and base64 encoding and decoding are needed
“password
"devOUI" string 32,// device MAC address
String 64,// device hardware Serial number
"SoftSN" Strring 64,// device software Serial number
"devVersion" string 64,// device version i-Ware software, version 6610P03. Device side sampl _ get _ version ()
"firmware": string// version name, build-fw-6610P03.Bin
}。
After receiving a first request sent by the intranet device, the centralized control device feeds back a cookie value of the centralized control device to the intranet device, so that the intranet device may send a second request, specifically, the second request is used to obtain a token value of the centralized control device, a data format of the second request is a json format, and in a specific embodiment, a specific request format is as follows:
URL www.abt.com (centralized control equipment URL or IP, varying depending on the configuration)
URL:/v 1/userauthtwicket = BBB (ticket: must fill, BBB can fill arbitrarily, not clear the reason with ticket parameter, if useless can remove)
Type:GET
And Cookie, connect.sid = AAA, and the same user is ensured by using the reply obtained in the previous step.
After receiving the second request, the centralized control device generates a third request according to the cookie value and the token value, where the third request is used to initiate registration authentication to the centralized control device, and a data format of the third request is in a json format, and in a specific embodiment, a specific request format is as follows:
URL www.abt.com (centralized control equipment URL or IP, varying depending on the configuration)
URL:/v 1/userauthtwicket = BBB (ticket: must fill, BBB can fill arbitrarily, not clear the reason with ticket parameter, if useless can remove)
Type:POST
Cookie, token ID = CCC, connect.sid = AAA, (token ID of last reply is added in Cookie, AAA is set-Cookie in the latest response to ensure the same user)
The Body is carried, and the Body is required to be verified by the centralized control equipment.
The data format of the third request is specifically as follows:
{
string 128,// branch name, i.e. device name, requires base64 encoding and decoding
String 128,// access password, base64 encoding and decoding are required

String 64,// device hardware Serial number
"SoftSN" Strring 64,// device software Serial number
"devVersion" string 64,// device version i-Ware software, version 6610P03
"Firmware": string// version name build-fw-6610P03.Bin devONlineTime ": int// how long the device was started
}。
And after the centralized control equipment receives the third request, verifying the third request, and if the verification is successful, indicating that the intranet equipment is successfully registered on the centralized control equipment.
S200, after the intranet equipment is successfully registered on the centralized control equipment, receiving a protocol switching request of the intranet equipment and verifying the protocol switching request so as to establish a websocket channel between the centralized control equipment and the intranet equipment.
In this embodiment, the protocol switching request is used to switch an http protocol to a websocket protocol, so that a channel may be established between the centralized control device and the intranet device, and intranet penetration is implemented through the websocket channel, specifically, step S200 specifically includes:
after the intranet equipment is successfully registered on the centralized control equipment, receiving a protocol switching request of the intranet equipment and verifying the protocol switching request so as to switch an http protocol into a websocket protocol;
and sending protocol switching confirmation information to the intranet equipment to establish a websocket channel between the centralized control equipment and the intranet equipment.
In one embodiment, the request format of the protocol switch request is as follows:
URL www.abt.com (domain name obtained in the previous step)
URL:/v1/base D = xxx (the path taken in the previous step, the extra parameter xxx is the loginnName coded by base64, and the parameter is unique, and the centralized control equipment uses the parameter to find the corresponding equipment and the related information)
Type:GET
Cookie JSSIONID = CCC; sid = AAA, the centralized control device needs to check that the cookie is the same as that of the auth phase
Body: empty.
In other words, the protocol switching request process is a process of mutually performing message confirmation and reply between the centralized control device and the intranet device, and during specific implementation, an additional port does not need to be opened, and the websocket connection port and the service port of the centralized control device can be shared, so that one port with multiple purposes is realized, and the method is more suitable for complex networking of different use scenes of the devices.

In order to ensure the consistency between the request message and the corresponding message, consistency check is also required, and in specific implementation, the web request has a unique number, and the intranet device performs consistency check on the web request through the unique number.
Specifically, each request message is given a unique number, after receiving the request message, an object and the serial number binding are created, an expiration time is set, the server forwards the response request to the device, after the device responds, the device response result is given to the object, the response handler is called back, and the response handler is returned to the client request.
In addition, the present invention can also perform centralized management on multiple devices, specifically, a dictionary corresponding to the device number and the device object is maintained in the memory, and the corresponding device request obtains the device object according to the device number (the object stores attributes such as the websocket connection between the device and the platform, and the message number of the device). And then calling the websocket attribute maintained in the equipment object to communicate with the equipment and the information. By the intranet penetration technology, operation and maintenance personnel can conveniently maintain intranet equipment in different networks, and the operation and maintenance efficiency is improved.
Based on the intranet penetration method of the centralized control equipment, the invention also correspondingly provides centralized control equipment, which comprises the following steps: a processor and a memory;
the memory has stored thereon a computer readable program executable by the processor;
when the processor executes the computer readable program, the steps in the intranet penetration method of the centralized control device according to the above embodiments are implemented.
