And 105, acquiring the equipment identification information according to the first set of equipment information, the second set of equipment information and the third set of equipment information.
In this embodiment, the obtained three sets of device information include priorities, where the first set of device information is of a high priority, the second set of device information is of a medium priority, and the third set of device information is of a low priority, and then when obtaining the device information according to the obtained three sets of device information, it is determined whether there is higher priority device information, if there is higher priority device information, then higher priority device information is selected, if there is no higher priority device information, then lower priority device information is selected, after obtaining the device information, it is necessary to merge the obtained device information with the device network access method obtained in step 104, and finally obtain device identification information of the device, where the device identification information may be a device category, a device type, a device manufacturer, a device model, and a device network access method, or a device category, a device type, Equipment manufacturers and equipment network access modes.
It should be noted that the user-agent device library, the mac domain name device library and the mac device library mentioned in the above steps need to be preset in advance, and in the presetting process, a large number of device information libraries need to be acquired from the network, and then the acquired device information libraries are classified and fused to form the user-agent device library, the mac domain name device library and the mac device library used in the embodiment of the present invention.
Compared with the prior art, the method and the device for accessing the network acquire the user-agent field, the mac address and the domain name of the device when the device is accessed to the network; matching the user-agent field with a preset user-agent device library to obtain a first group of device information, wherein the preset user-agent device library comprises a 4-level user-agent device library and a 3-level user-agent device library; matching the mac address and the domain name with a preset mac domain name equipment library to acquire a second group of equipment information; matching the mac address with a preset mac equipment library to acquire a third group of equipment information and a network access mode of the equipment; the equipment information is acquired according to the first group of equipment information, the second group of equipment information and the third group of equipment information, the equipment information is fused with the equipment network access mode, and the equipment identification information of the equipment is acquired, so that the purpose of comprehensively using three information, namely a user-agent field, a mac address and a domain name, for equipment identification is achieved, and the problem that the accuracy of terminal identification is low due to single information identification in the prior art is solved.
A second embodiment of the present invention relates to a device identification method, which is substantially the same as the device identification method provided in the first embodiment, except that, as shown in fig. 2, step 102 includes:
In this embodiment, the high-priority keyword may be obtained only when the obtained user-agent field exists in a standard form, where the standard form refers to that the device information in the user-agent field appears at a position where the device information should appear, and the standard user-agent field is as follows: dalvik/2.1.0 (linux; u; android 6.0.1; oppo r9s built/mmb 29m), because the device information of the standard user-agent field is obvious, a method of direct acquisition may be adopted, for example, the obtained high-priority key is oppo r9s, when the high-priority key acquisition is successful, step 202 is executed, and when the high-priority key acquisition is failed, step 203 is executed.
In this embodiment, the high-priority keyword obtained in step 201 is matched with the device information in the 4-level user-agent device library, and if the matching is successful, step 209 is executed, and if the matching is not successful, step 203 is executed.
In this embodiment, when the high-priority keyword fails to be obtained, it is determined that the obtained user-agent field is not in a standard format, and at this time, a non-violent word segmentation method needs to be used to obtain a medium-priority keyword from the obtained user-agent field, where the presence of the medium-priority keyword indicates that the obtained format of the user-agent field is non-standard, but the device information thereof is still obvious, for example, the style of the user-agent field is as follows: 1605-a01_6.0.1_ weibo _9.4.2_ android _ wifi, the medium priority key mentioned is: 1605-a01, wherein the non-violent segmentation method means that segmentation methods other than the violent segmentation method can be used, step 204 is executed when the acquisition of the medium priority keyword is successful, and step 205 is executed when the acquisition of the high priority keyword is failed.
And step 204, judging whether the matching with the 4-level user-agent equipment library is successful.
In this embodiment, the high-priority keyword obtained in step 203 is matched with the device information in the 4-level user-agent device library, and if the matching is successful, step 209 is executed, and if the matching is not successful, step 205 is executed.
In this embodiment, when the acquisition of the medium-priority keyword fails, it indicates that the acquired user-agent field is not in a standard format and the device information is not obvious, at this time, a brute force word segmentation method needs to be used to acquire a low-priority keyword from the acquired user-agent field, and the presence of the low-priority keyword indicates that the format of the acquired user-agent field is non-standard and the device information is not obvious, where the brute force word segmentation method is to forcibly calculate the possible probabilities of all words in the user-agent field, then select the most appropriate word according to the probabilities of the words, and execute step 206 when the acquisition of the low-priority keyword succeeds, and execute step 207 when the acquisition of the high-priority keyword fails.
In this embodiment, the high-priority keyword obtained in step 204 is matched with the device information in the 4-level user-agent device library, and if the matching is successful, step 209 is executed, and if the matching is not successful, step 207 is executed.
And step 207, acquiring new keywords according to the high, medium and low priority keywords of the user-agent field.
In this embodiment, when the high, medium and low priority keywords are all unsuccessfully matched with the device information in the 4-level user-agent device library, the high, medium and low priority keywords need to be collected and deduplicated to obtain new keywords, for example: the high priority keyword is OPPO r9s, the medium priority keyword is OPPO, the low priority keyword is o, the new keyword is OPPO, when the new keyword is successfully acquired, step 208 is executed, when the new keyword is unsuccessfully acquired, step 103 is executed.
And step 208, judging whether the matching with the 3-level user-agent equipment library is successful.
In this embodiment, the high-priority keyword obtained in step 201 is matched with the device information in the 3-level user-agent device library, and if the matching is successful, step 209 is executed, and if the matching is not successful, step 301 is executed.
In step 209, a first set of device information is obtained.
In this embodiment, when the obtained keyword is successfully matched with the device information in the user-agent device library, the device information in the user-agent device library corresponding to the keyword is obtained, and the obtained device information is used as the first set of device information, where the first set of device information may be a device class, a device type, a device manufacturer, a device model, or a device class, a device type, or a device manufacturer.
