Judging whether the information of the requesting client is already in the established active user list, the active user list stores information of clients who have visited the server within the set time period:

If not: then the client accesses the server for the first time within the set time period, and the information of the client is added to the active user list;

If so, it is not the first time that the client accesses the server within the set time period.

In this embodiment, the client information includes client id information, and the active user list stores id information of clients that have accessed the server within the set time period.

FIG. 4 illustrates in detail the flow of the upgrade method in this embodiment by taking a client sending a request to a server as an example.

As shown in Figure 4, when the user sends a request to the server to obtain a list of applications that can be upgraded, the user will send all installed applications and their versions to the server; the server first queries the database and returns the applications that can be upgraded to the user;

The server continues to run in the background, first query the active user id list of this week (the time period set in this embodiment is one week), if this user is not visiting for the first time this week, then end;

If this user visits for the first time this week, for all the applications installed by this user, find the application in this week's application sorting list, if found, add 1 to the installation amount, if not, add the installation amount of this application Set to 1; when the number of installations changes, dynamically adjust the sorting of the apps in the app sorting list.

The active user list and the application sorting list in this embodiment take a set period of time as a cycle, and data of a new cycle is written after the next cycle starts. For example, if the serial number of this week is 2201, then the list of active users this week is USER_2201, and the list of application rankings this week is APPRANK_2201; the serial number will become 2202 next week;

There are three apps with ids of 4, 5, and 6 respectively, and the installation volumes recorded in APPRANK_2201 are 10,000, 1,000, and 100 respectively;

User A installs two apps with ids 4 and 5, and A visits for the first time this week, so the installations of 4 and 5 in APPRANK_2201 are increased by one to become 10001 and 1001 respectively; and user A is placed in USER_2201;

User B has installed two applications with ids 5 and 6, and if B is not visiting for the first time this week, the server will not process it;

At this time, the installation volume of applications in APPRANK_2201, 4, 5, and 6 are 10001, 1001, and 100 respectively; the server is sorted according to the installation volume, and the installation volume of application 4 ranks in the forefront, and the crawler crawls it every 10 minutes; the installation volume of application 5 ranks In the middle, the crawler crawls once every hour; the installation volume of application 6 is ranked last, and the crawler crawls once a day.

In this embodiment, based on the user's access, the applications installed by the user are sorted according to the installation volume, and the sorting of the installation volume is used as a basis for adjusting the frequency of application capture, so that popular applications can be updated in a timely manner.

As shown in Figure 5, it is a schematic structural diagram of an application upgrading system in this embodiment, including:
