According to the present method, usage rate of network and system resources is improved.

Abstract: This application discloses an information processing method performed at an application server. The application server receives a first virtual article identifier and a first account sent by a terminal in response to an operation of a user on a virtual article presentation interface. The server generates and stores a first order including the first virtual article identifier and the first account, obtains a current bill provided by a payment system and forwarded by the terminal, and a second account used to log into the terminal. The server determines a second order corresponding to the current bill, associates the current bill with the second order when a virtual article identifier and an account in the second order are the same as the second virtual article identifier and the second account; and sends a virtual article corresponding to the second virtual article identifier to the second account.

Abstract: A method and apparatus for sending a delivery notification of a network application-related product are provided. The method includes: selecting a delivery executing server in advance from multiple delivery servers of an application; acquiring quality of service information of the delivery executing server of the application; judging, according to a predefined judging rule, whether the quality of service information meets a requirement; and if the requirement is met, retaining the delivery executing server unchanged; otherwise, setting another delivery server of the application as a delivery executing server; and sending a delivery notification to a current delivery executing server of the application upon detecting the delivery notification of the application to be sent.

Abstract: It is described an information processing method. On a display screen of a terminal it is presented at least one piece of promotion information associated with an application when the application is running on the terminal. Upon detecting that one piece of the promotion information is selected, a payment platform which is in-built in the application is triggered to perform the following: requesting a server to determine whether a payment option corresponding to the selected piece of the promotion information shall be presented on a first page or a second page; jumping to the first page upon reception from the server of a first operation instruction of presenting the payment option corresponding to the selected piece of the promotion information on the first page; and presenting on the first page the payment option corresponding to the selected piece of the promotion information.
