Embodiments of the invention

Referring to FIG. 1, an embodiment of a message pushing method in the embodiment of the present application may include:

Step S101: Acquire a window title name displayed on the user's terminal device.

The window title name may be a title name in a title bar of an application (APP) window currently being used by the user.

Specifically, the idProcess and idThresd in the application programming interface (API) provided by the system of the terminal device may be blanked to obtain all user process messages in the current system, and then processed by the process processing function. The message finally identifies these processed user process messages, so as to obtain the process name of the application and the window title name of the open window without affecting the normal operation of the application.

Optionally, the Hook function may be registered in the terminal device to monitor a process of accessing the application, and the Hook function registered in the terminal device acquires a user process message of a process of accessing the application. Among them, the Hook function, that is, the hook function, is a platform of the message processing mechanism. The application can set the subroutine to monitor the window message, and the monitored window can be created by other processes. When the window message arrives, The window message is processed before the window handler is executed.

In addition, the Hook mechanism allows the application to intercept processing messages or specific events. The hook is actually a program segment that processes the message. The Hook function is hooked into the system through the system call. Before the pop-up message reaches the target window, the Hook function first. The window message is captured, and the Hook function can process the window message, or continue to deliver the window message without processing, and can also force the end of the window message delivery.

Step S102, sequentially matching the window title name with each keyword in the preset keyword configuration file.

Preferably, before the window title name and the keywords in the preset keyword profile are sequentially matched, the keyword profile may also be updated by a process as shown in FIG. 2:

Step S201: Send a configuration update request to a preset configuration server.

Since the keyword may be constantly changing over time, the keyword profile will be constantly changed accordingly, and the configuration server is configured to store the current latest keyword profile to provide updated standards for the terminal device.

Step S202, receiving configuration information fed back by the configuration server.

The configuration information includes a first message digest value, where the first message digest value is a message digest value obtained by processing a keyword configuration file in the configuration server by using a preset message digest algorithm, in this example. The message digest algorithm may be an MD5 algorithm, a SHA-1 algorithm, and other similar algorithms. The message digest algorithm can transform an input of any length into a fixed-length output. This conversion is a compression mapping, that is, the length of the output is usually much smaller than the length of the input, and different inputs may be hashed to the same output. It is not possible to uniquely determine the input value from the output value, which is simply a process of compressing a message of any length into a message summary of a fixed length.

Step S203, determining whether the first message digest value is consistent with the second message digest value.

The second message digest value is a message digest value obtained by processing the locally stored keyword configuration file by using the message digest algorithm.

If the first message digest value is inconsistent with the second message digest value, it indicates that the locally stored keyword configuration file is inconsistent with the keyword configuration file in the configuration server, that is, the locally stored keyword configuration file. If it is not the latest version, it needs to be updated. In this case, step S204 is performed. If the first message digest value is consistent with the second message digest value, the locally stored keyword configuration file is compared with the configuration server. The keyword configuration file is consistent, that is, the locally stored keyword configuration file is already the latest version, and there is no need to update it. At this time, step S205 is performed.

Step S204: Download a keyword configuration file in the configuration server, and replace the locally stored keyword configuration file with a keyword configuration file in the configuration server.

In step S205, the locally stored keyword profile is maintained.

The foregoing process is a process in which the terminal device actively updates the keyword configuration file. In another possible implementation of the embodiment, the configuration server may instruct the terminal device to perform the update of the keyword configuration file, that is, when the configuration server When the keyword configuration file is changed, the configuration server sends the current latest keyword configuration file to the terminal device, and after receiving the configuration file, the terminal device replaces the locally stored keyword configuration file with the configuration file.

The keyword configuration file includes a subset of keywords corresponding to preset various message types, and each keyword subset includes more than one keyword. For example, message types such as an advertisement class, a news information class, and a system notification class may be classified, and each type of push information is set with a corresponding keyword subset. For example, the keyword subset of the advertisement category may include keywords such as "advertisement", "promotion", "offer", and "price reduction".

Preferably, the priority may be set for each keyword, which may be set by the user according to his own usage habits, which is not specifically limited in this embodiment.

When performing matching, first selecting a keyword with the highest priority and not yet selected as the current keyword from the keyword configuration file, and then searching for the current keyword in the window title name, if If the current keyword is not found in the window title name, returning to perform the step of selecting a keyword having the highest priority and not yet selected from the keyword profile as the current keyword, if If the current keyword is found in the window title name, it is determined that the window title name matches the current keyword successfully. If all the keywords have been traversed and no keyword has been found in the window title name, it is determined that the matching has failed.

In step S103, it is determined whether the matching is successful.

That is, it is determined whether any one of the keyword profiles is included in the window title name. If the matching is unsuccessful, step S104 is performed, and if the matching is successful, step S105 and subsequent steps are performed.

In step S104, no message push is performed.

Step S105, determining a message type corresponding to the keyword whose window title name is successfully matched as a preferred message type.

Step S106: Select a specified number of preferred push messages in the preset push message database, and push the selected preferred push messages to the terminal device.

The preferred push message is a push message whose message type is consistent with the preferred message type.

Specifically, firstly, the number of pushes and the number of clicks of each preferred push message in a specified time period are respectively obtained from the historical statistical records, and then the preferred index of each preferred push message is separately calculated according to the following formula:

Where n is the sequence number of the preferred push message, 1≤n≤N, N is the total number of preferred push messages, ClickNum _n is the number of clicks of the nth preferred push message, and SendNum _n is the number of pushes of the nth preferred push message. , min is the minimum function, ξ ₁ and ξ ₂ are preset weight coefficients, and ξ ₁ + ξ ₂ =1, for example, ξ ₁ = ξ ₂ = 0.5 can be set, PriIndex _n is the nth preferred push message Preferred index.

Finally, a specified number of preferred push messages are sequentially selected from the push message database in descending order of the priority index.

Preferably, the specified number of setting processes may include:

First, the display duration of the window title name on the terminal device is obtained.

Then, the display duration of the window title name on each target device within a specified time period is respectively obtained from the historical statistical record.

The target device is a terminal device that is a statistical object of the historical statistical record.

Finally, the specified number is calculated according to the following formula:

Wherein, ShowTime is the display duration of the window title name on the terminal device, hn is the serial number of the target device, 1≤hn≤HN, HN is the total number of target devices, and HiShowTime _hn is the name of the window title. The display duration on the hn target devices, BenchNum is the preset number of references, and the value can be set according to the actual situation. For example, it can be set to 3, 5, 10, and so on. MaxTime=max(HiShowTime ₁ , HiShowTime ₂ , ..., HiShowTime _hn , ..., HiShowTime _HN ), min is the minimum function, max is the maximum function, and floor is the rounding function. , SNum is the specified number.
