and sending the equipment identification to the external server.
4. The method of claim 1, wherein obtaining mapping list information corresponding to a preselected file path in the electronic device comprises:
selecting a file path according to an operating system corresponding to the electronic equipment to obtain a preselected file path;
determining a preselected file according to the preselected file path;
extracting index nodes of the preselected file to obtain index node information;
and mapping the preselected file paths and the index node information one by one to obtain mapping list information.
5. The method of claim 4, wherein selecting the file path according to an operating system corresponding to the electronic device to obtain a preselected file path comprises:
acquiring trigger information;
and selecting a file path according to an operating system corresponding to the electronic equipment based on the trigger information to obtain a preselected file path.
6. An apparatus for acquiring device identification, the apparatus being applied to an electronic device, the apparatus comprising:
an obtaining module, configured to obtain a first request, where the first request is used to obtain a device identifier;
the obtaining module is further configured to obtain mapping list information corresponding to a preselected file path in the electronic device;
the obtaining module is further configured to obtain non-privacy device information corresponding to the electronic device;
the determining module is used for filtering the mapping list information based on the non-privacy equipment information to obtain to-be-processed mapping list information containing to-be-processed mapping values; determining a summary value according to the mapping list information to be processed and the non-privacy equipment information; coding the abstract value to obtain a device identifier;
the determining module is specifically configured to put the mapping value to be processed into an empty character string buffer according to a dictionary sequence, and obtain an intermediate buffer containing first data; according to the dictionary sequence, the information of the non-privacy equipment is placed at the tail part of the middle buffer area, and a buffer area to be processed containing second data is obtained; and determining a digest value according to the second data.
7. The apparatus of claim 6, further comprising:
and the feedback module is used for feeding back the equipment identifier to the internal server.
