Example 1
In accordance with an embodiment of the present application, there is provided an embodiment of a device connection method, it should be noted that the steps shown in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions, and that while a logical order is shown in the flowchart, in some cases the steps shown or described may be performed in an order different than here.
Fig. 1 is a device connection method according to an embodiment of the present application, and as shown in fig. 1, the method includes the steps of:
step S102, obtaining target information of a first device in a target local area network, wherein the target information comprises an IP address of the first device and a serial number of a target service port for connecting with a second device in the target local area network.
In some optional embodiments of the present application, all available service ports of the first device may be numbered first, then the serial number of the target service port used for connecting with the second device is determined, and at the same time, the IP address of the first device is determined, and the IP address and the serial number of the target service port are used as the target information of the first device.
Optionally, the target information further includes a target check code generated by the first device, where the target check code is a number randomly generated by the first device within a preset value range, and a specific value range may be defined by a user, for example, 0 to 15. In some optional embodiments of the present application, the target check code may be dynamically refreshed over time, that is, the first device may generate a new target check code every other fixed time period, so as to ensure the security of device connection.
Step S104, generating a target connection code according to the target information, wherein the target connection code corresponds to a plurality of connection information, each connection information comprises an IP address and a service port serial number, and the plurality of connection information comprises the target information.
It is understood that the target connection code is generated according to the target information, and therefore the target information is necessarily included in the connection information corresponding to the target connection code. When the target information comprises the target check code, each piece of connection information corresponding to the target connection code also comprises a check code.
In some optional embodiments of the present application, the process of generating the target connection code according to the target information includes steps S1040-S1048:
step S1040, a binary first code is generated according to the sequence number of the target service port.
Specifically, a first value range of the serial number of the available service port of the first device is obtained, the first value range is averagely divided into a first preset number segment value range, and the smallest segment value range is used as a second value range, wherein the second value range is the value range of the first code.
Then, judging whether the serial number of the target service port is in a second value range; if the serial number of the target service port is in the second value range, generating a first code according to the serial number of the target service port; and if the serial number of the target service port is not in the second value range, determining a first target value corresponding to the serial number of the target service port in the second value range, and generating a first code according to the first target value.
For example, 4 available service ports of the first device are respectively numbered as 0, 1, 2, and 3, the first value range is 0-3, the first value range is averagely divided into 2 segments, the second value range is 0-1, and the generated first code takes values within 0-1; if the serial number of the target service port is 1 and is within a second value range of 0-1, a binary first code is directly generated as 1 according to 1; assuming that the sequence number of the target service port is 3 and is not within the second value range 0-1, it needs to first determine that the corresponding first target value is 3-2=1 (2 indicates that the second value range includes 2 numbers), and then generate the binary first code as 1 according to 1.
It can be seen that 1 of the first code may correspond to a plurality of service port sequence numbers, which may indicate that the service port sequence number is 1, or may indicate that the service port sequence number is 3, and the specific meaning needs to be determined by retry at the time of connection. Through the above process, the first code which originally needs 2 bits (0-3 corresponds to binary 00-11) can be shortened to 1bit (0-1 corresponds to binary 0-1) for representation.
In some optional embodiments of the present application, the first code may not be generated, that is, the target information does not include the serial number of the target service port, and when performing device connection, the first code may directly and sequentially attempt to connect with a plurality of available service ports of the first device.
Step S1042, a binary second code is generated according to the target check code.
Similar to the process of generating the first code, a third value range of the available check code of the first device is obtained, the third value range is averagely divided into a second preset number segment value range, and the smallest segment value range is used as a fourth value range, wherein the fourth value range is the value range of the second code.
And then. Judging whether the target check code is in a fourth value range or not; if the target check code is in the fourth value range, generating a second code according to the target check code; and if the target check code is not in the fourth value range, determining a second target value corresponding to the target check code in the fourth value range, and generating a second code according to the second target value.
For example, a user presets a third value range of the available check code to be 0-15, the third value range is divided into 2 sections on average, a fourth value range of 0-7 is obtained, and the generated second code takes values within 0-7; if the target check code is 6 and is within the fourth value range of 0-7, a binary first code 110 is directly generated according to 6; assuming that the target check code is 13 and is not within the fourth value range 0-7, it needs to first determine that the corresponding second target value is 13-8=5 (8 indicates that the second value range includes 2 numbers), and then generate the binary first code 101 according to 5.
If the third value range 0-15 is averagely divided into 4 sections, a fourth value range 0-3 is obtained, and the generated second code takes values within 0-3; if the target check code is 2 and is within the fourth value range of 0-3, directly generating a binary first code 10 according to 2; assuming that the target check code is 6 and is not within the fourth value range 0-3, it needs to first determine that the corresponding second target value is 6-4=2 (4 indicates that the second value range includes 4 numbers), and then generate a binary first code 10 according to 2; assuming that the target check code is 13 and is not within the fourth value range 0-3, it is required to first determine that the corresponding second target value is 13-4-4-4=1, and then generate a binary first code 1 according to 1.
Through the above process, the second code originally needing 4 bits (0-15 corresponding to binary 0000-1111) can be shortened to 3 bits (0-7 corresponding to binary 000-111) or even 2 bits (0-3 corresponding to binary 00-11) for representation.
Step S1044 is to generate a binary third code according to the IP address of the first device.
In some optional embodiments of the present application, different encoding strategies may be applied to different types of IP addresses, and therefore, the IP address type of the first device may be determined first, where the IP address type includes a class a address, a class B address, and a class C address, the class a address range is 10.0.0.0 to 10.255.255.255, the class B address range is 172.16.0.0 to 172.31.255.255, the class C address range is 192.168.0.0 to 192.168.255.255, and each class IP address includes four bytes.
Then, for any byte of the IP address of the first device, determining a fifth value range of the byte, averagely dividing the fifth value range into a third preset number segment value range, and taking the smallest segment value range as a sixth value range; judging whether the value of the byte is in a sixth value range or not; if the value of the byte is in the sixth value range, generating a sub-code corresponding to the byte according to the value of the byte; if the value of the byte is not in the sixth value range, determining a third target value corresponding to the value of the byte in the sixth value range, and generating a sub-code corresponding to the byte according to the third target value; finally, the third code is determined according to the sub-codes corresponding to the bytes of the IP address of the first device, and usually, the sub-codes corresponding to the four bytes of the IP address of the first device are combined to obtain the third code.
For example, if the IP address of the first device is 192.168.126.128, the following processing may be performed for each byte: determining the fifth value range to be 0-255, and averagely dividing the fifth value range into 2 sections to obtain a sixth value range of 0-127; if the first byte 192 is not within the sixth value range 0 to 127, the third target value corresponding to the first byte 192 is determined to be 192 to 128=64, and then the binary sub-code is generated to be 1000000 according to 64; if the second byte 168 is not within the sixth value range 0-127, it is determined that the corresponding third target value is 168-128=40, and then a binary sub-code 0101000 is generated according to 40; if the third byte 126 is in the sixth value range 0-127, the binary sub-code 1111110 is directly generated according to the third byte 126; if the fourth byte 128 is not within the sixth value range 0-127, it is determined that the corresponding third target value is 128-128=0, and then the binary sub-code is generated as 0000000 according to 0; finally, the sub-codes corresponding to the four bytes are combined to obtain a 28-bit third code 1000000010100011111100000000, which is 4 bits shorter than the original 32 bits.
It should be noted that, for different bytes of the IP address of the first device, the determined fifth value ranges may be different, and the number of segments obtained by averagely dividing the fifth value ranges may also be different, and if the fifth value ranges are divided into one segment, it means that the binary sub-code is directly generated according to the value of the byte.
For example, when the IP address type of the first device is a class B address, since the value range of the second byte is 16 to 31, when the second byte is processed, 0 to 31 may be used as the fifth value range, and the fifth value range is averagely divided into 2 segments, so that the sixth value range is 0 to 15; assuming that the IP address of the first device is 172.31.255.255, since 31 is not in the eighth value range 0-15, it is determined that the corresponding fourth target value is 31-16=15, and then a binary sub-code 1111 is generated according to 15, where the bit number is only 4 bits.
Since the IP address is usually partitioned from the previous segment, for example, 10.xx.xx.xx may be divided into 10.0.xx.xx-10.2.xx.xx and 10.12.xx.xx-10.16.xx.xx, the fifth value range of the first two bytes may be divided into 2 segments on average when determining the sub-code corresponding to each byte, and the sub-code is determined according to the above process; and averagely dividing the fifth value range of the last two bytes into 1 segment, namely directly generating the sub-code according to the value of the bytes.
In some optional embodiments of the present application, since the first byte (i.e., the flag bit) of the class a IP address is fixed to 10, the first byte of the class B IP address is fixed to 172, the first two bytes of the class c IP address are fixed to 192.168, when the IP address type of the first device is the class a address or the class B address, sub-codes corresponding to the last three bytes of the IP address of the first device are combined to obtain a third code; and when the IP address type of the first equipment is the C-type address, combining the sub-codes corresponding to the last two bytes of the IP address of the first equipment to obtain a third code. When the device is connected, the zone bit of the IP address can be determined directly by adopting a retry mode.
For example, if the IP address of the first device is 192.168.126.128 and the first device is a C-type address, the sub-code 1111110 corresponding to the third byte and the sub-code 0000000 corresponding to the fourth byte need only be combined to obtain the third code 11100000000 corresponding to the IP address.
Step S1046, combining the first code, the second code, and the third code to obtain a binary fourth code.
And step S1048, converting the fourth code from binary to decimal to obtain the target connection code.
Assuming that the serial number of the target service port used by the first device for connecting with the second device is 3, the generated check code is 15, the ip address is 10.255.255.255, if the information is directly represented by the real value when the connection code is generated, the obtained first code is 11, the second code is 1111, the third code is 00001010111111111111111111111111111111111111111, the combination of the first code and the third code is 38 bits of the fourth code 11111100001010111111111111111111111111111111111111111111, the target connection code converted into decimal is 270767489023, and the number of bits is 12 bits. If it is determined that each value range is equally divided into two segments and the first byte of the IP address is omitted when the target connection code generation process is adopted, the first code is 1, the second code is 111, the third code is 111111111111111111111 are obtained respectively, the first code, the second code and the third code are combined to obtain the fourth code 1111111111111111111111111111111111 which has 25 bits in total, and the target connection code converted into the decimal code is 33554431, and the number of bits of the target connection code is only 8 bits. It can be seen that the number of bits of the target connection code obtained through the above process is greatly shortened, and the extra space occupation is reduced.
And step S106, sending the target connection code to the second equipment, and establishing connection with the second equipment according to the target information corresponding to the target connection code.
In some optional embodiments of the present application, the target connection code is sent to the second device, and the second device parses a plurality of connection information corresponding to the target connection code; receiving a plurality of connection requests sent by second equipment according to a plurality of connection information, wherein each connection information corresponds to one connection request; and determining whether the connection information corresponding to each connection request is the same as the target information or not, and establishing connection with the second equipment when the connection information is the same as the target information.
Specifically, after the target connection code is sent to the second device, the second device reversely analyzes a plurality of connection information corresponding to the target connection code according to the target connection code generation process, and sends a connection request to the first device according to each connection information to try to establish connection with the first device; after receiving a connection request, the first device compares connection information corresponding to the connection request with its own target information, and if the connection information is the same as the target information, that is, the connection information includes a serial number of a target service port used by the first device to connect with the second device, a target check code generated by the first device, and an IP address of the first device, then the first device establishes a connection with the second device.
For example, the serial number of the target service port used by the first device to connect with the second device is 3, the generated check code is 15, the ip address is 10.255.255.255, and the connection code is generated according to the connection code generation process 33554431 and sent to the second device.
