Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
Hereinafter, the terms "including", "having", and their derivatives, which may be used in various embodiments of the present invention, are only intended to indicate specific features, numbers, steps, operations, elements, components, or combinations of the foregoing, and should not be construed as first excluding the existence of, or adding to, one or more other features, numbers, steps, operations, elements, components, or combinations of the foregoing.
Furthermore, the terms "first," "second," "third," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.
Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which various embodiments of the present invention belong. The terms (such as those defined in commonly used dictionaries) should be interpreted as having a meaning that is consistent with their contextual meaning in the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein in various embodiments of the present invention.
Example 1
step S101, acquiring a DHCP message sent to a router by a terminal;
specifically, a terminal where a user is located does not directly access a cloud platform site, and the terminal accesses the cloud platform site through a router, so that a DHCP message sent to the router by the terminal can be acquired, and the system type of the terminal can be determined through the DHCP message.
Specifically, the user terminal equipment can trigger the DHCP negotiation process every time when being associated with the router so as to obtain the IP address to carry out subsequent internet surfing requirements, the user terminal can send a DHCP DISCOVER message and a DHCP request message in the process, the two messages can fill a terminal system type field, but the terminal can frequently send the DHCP DISCOVER message when not being associated with any router equipment, the data volume is too large, monitoring is not facilitated, and only the DHCP request message is processed at the position. Thereby saving system resources. Therefore, in a specific embodiment, the DHCP message is a DHCP request message.
Step S102, if a designated field exists in the DHCP message, extracting the identification of the system corresponding to the terminal from the designated field, and determining the system type of the terminal based on the identification;
specifically, the "determining the system type of the terminal based on the identifier" in step S102 includes:
searching a system type corresponding to the identifier in a preset corresponding relation table; the corresponding relation table comprises corresponding relations between the identifications and the system types; and setting the searched system type as the system type of the terminal.
Specifically, the designated field is an option60 field. The operating system type can be obtained based on an option60 field in a DHCP request message, and the field can be filled by a currently popular terminal, for example, a Windows system keyword is MSFT, an Android system keyword is Android, and the corresponding relationship between the operating system type and the DHCP option can be as follows:
TABLE 1
| Type of system | option60 field |
| windows | MSFT |
| android | android |
| ios | N/A |
| linux | N/A |
Specifically, as shown in fig. 2A and 2B, the DHCP request message may be known to have a windows system and an android system according to an option60 field.
Specifically, step S102 may be implemented by modifying a dhcpd open source code, specifically, as shown in fig. 4, a message analysis function may be added in the dhcpd module to process an option60 field in a dhcp request message, and a corresponding relationship is established between an MAC (Media Access Control Address, chinese name Media Access Control Address, also called local area network Address) of the terminal and a system type, and is stored in a flash;
there may be a case that the DHCP request message sent by some terminal systems does not carry the option60 field, and this type of terminal system information scheme will be obtained by analyzing the HTTP protocol message in the following, that is, step S103 is executed.
Step S103, if no designated field exists in the DHCP message, acquiring an HTTP message sent to the router by the terminal, extracting a UA message header from the HTTP message, and determining the system type of the terminal based on the UA message header.
And aiming at the terminal equipment which does not carry the option60 field in the DHCP request message, the type of the terminal system can be identified by monitoring the HTTP message and then extracting the UA in the message header of the HTTP header. The UA message header is called User-Agent completely, belongs to HTTP header standard field, and contains browser type, version number, operation system type and version number. Through a large number of tests, HTTP messages of different terminal devices are captured, and the corresponding relation between the type of an operating system and a UA message header can be found as the following table;
TABLE 2
Specifically, as shown in fig. 3A, 3B, 3C, and 3D, the corresponding system types are linux type, windows type, ios type, and android type.
Specifically, the acquiring the HTTP message sent by the terminal to the router and extracting the UA message header from the HTTP message includes: starting a preset process to acquire an HTTP message sent by the terminal to the router; extracting a Mac address and an IP address in the HTTP message; and if the extracted Mac address and the extracted IP address are completely matched with the Mac address and the IP address in the list to be processed, extracting a UA message header from the HTTP message, and deleting the completely matched Mac address and IP address in the list to be processed.
In addition, this scheme still further includes: and if the Mac address and the IP address do not exist in the list to be processed, terminating the preset process.
As shown in fig. 5, if the request message does not carry an option60 field, checking whether the terminal system type processing module is operated in the current system, if not, directly pulling up the module for the next processing, if the module is in the operation stage, notifying the terminal system type processing module ClientUAMonitor of the MAC address and the IP address of the terminal device through an IPC process message communication mechanism, and thus, completely taking over the terminal system type processing module by the ClientUAMonitor; here, the terminal system type processing module ClientUAMonitor is newly added and is mainly used for acquiring a UA field of an HTTP protocol packet of the device terminal. After the module is started, the MAC and the IP addresses of the equipment to be processed are firstly obtained, a list of the MAC to be processed is maintained, then a raw socket is created, and only HTTP messages are processed.
By reading the MAC and IP addresses in the HTTP message, if the MAC and IP addresses are found to be completely matched with the MAC and IP addresses to be processed, the UA message header field of the HTTP message is extracted and stored to a flash, and meanwhile, the MAC entry in the list to be processed in the module is deleted. In addition, whether data exist in the list to be processed in the terminal system type processing module is also checked, if so, the flow is continued, and if the list is empty, the exit is ended.
