Petal Cloud Technology Co., Ltd.

A database (DB) file backup method and apparatus, and an electronic device are provided. The method includes: an electronic device segments a DB file, to obtain local subfiles of the DB file, obtains a first local subfile from the local subfiles, and uploads the first local subfile to a server, where the first local subfile is a local subfile that does not have a corresponding server side subfile in the server; and/or obtains a second local subfile from the local subfiles, and uploads the second local subfile to the server, where the second local subfile is a local subfile that has a corresponding server side subfile in the server and that corresponds to a content comparison result indicating that the second local subfile and the corresponding server side subfile are inconsistent. In this case, a local subfile whose content does not change is not uploaded each time.

A terminal sends, to a server, a request for obtaining details page content of first information, where the request includes an identifier of a user and an identifier of the first information. The server determines, based on the identifier of the user and the identifier of the first information, the details page content of the first information, where the details page content is different from preset details page content of the first information. The server sends the details page content of the first information to the terminal. The terminal displays, based on the details page content of the first information, a details page of the first information.

This application provides a page display method and apparatus, and relates to the field of data transmission. The method includes: performing, by a terminal device, a first interaction operation with a first object; downloading, by the terminal device, the corresponding first file from a server based on the identification information of the first file; storing, by the terminal device, the first file, and displaying a corresponding first page based on the first file; receiving, by the terminal device, a first operation, where the first operation is an operation of opening the first page by a user; and displaying, by the terminal device, the first page again in response to the first operation.

A first application of a second electronic device obtains at least one piece of location information. After the first application obtains the at least one piece of location information, the second electronic device scans a first BLUETOOTH broadcast from a first electronic device. The second electronic device obtains first location information based on the first BLUETOOTH broadcast, where the first location information is at least one of the at least one piece of location information. The second electronic device reports the first location information to a server. The second electronic device may use location information obtained by another application on the second electronic device. When the second electronic device obtains the BLUETOOTH broadcast through scanning, the second electronic device does not need to frequently invoke a second application to obtain location information.

A method includes displaying a preview screen in response to a detected first operation; determining a first virtual object in response to a detected second operation; obtaining positioning information of the first virtual object, and displaying the first virtual object on the preview screen based on the positioning information; and synthesizing a first image and a second image based on the positioning information to obtain a third image. The first image includes a real environment picture. The second image includes a second virtual object corresponding to the positioning information. The second virtual object is generated by rendering the first virtual object based on ambient light information. The ambient light information corresponds to the real environment picture.

A method for displaying an associated term includes obtaining a search term entered in a search bar; determining an associated term corresponding to the search term; determining an application corresponding to the associated term; and displaying the associated term and an identifier corresponding to the associated term, where the identifier is used to open the application corresponding to the associated term corresponding to the identifier. The method for displaying the associated term may facilitate interaction between a user and another application on the terminal device when the user performs searching in a search engine of the terminal device.

A terminal device sends resource access request information to a server, and the resource access request information carries a user identity and an identifier of a to-be-accessed resource. The server performs authentication on the user identity. If the authentication succeeds, the server obtains location information of the terminal device, and the location information includes geographical location information and positioning assistance information. The server attempts to verify the location information of the terminal device. If the verification succeeds, the server sends an access token corresponding to the identifier of the to-be-accessed resource to the terminal device. The terminal device obtains the to-be-accessed resource based on the access token.

An application login method for accessing an application server by an application includes techniques for an authentication server to complete login authentication on a client application based on authorization request information of the client application in a login request received from a client terminal, determining an application server in a user home country/region of the client application based on user home country/region identification information of the client application in the login request, generating and sending access information about the application server in the user home country/region of the client application.

The method includes performing Bluetooth authentication with a terminal based on Bluetooth authentication information; after the Bluetooth authentication with the terminal succeeds, obtaining RFID authentication information, where the RFID authentication information includes label information and authorization information of an RFID label, and the authorization information is used to indicate an association relationship between the RFID label and the terminal; and performing RFID authentication based on the RFID authentication information, and being in a controllable state after the RFID authentication succeeds.

An advertisement delivery method includes: receiving an advertisement request sent by a first terminal device, where the advertisement request includes an application identifier and a device identifier of the first terminal device. Based on the device identifier, a target advertisement creative from a preset advertisement creative library corresponding to the application identifier is determined. The preset advertisement creative library includes at least one advertisement creative uploaded by an advertiser to the cloud server. A target advertisement material from a preset material library is determined based on the target advertisement creative and the device identifier. The target advertisement material is spliced, based on the target advertisement creative, to obtain the target advertisement, which is then delivered to an advertisement slot.
