Abstract: Embodiments of the present invention provide a method for presenting reposted messages. The method includes: respectively establishing, in a server for each piece of original message X, a reposting chain, which takes the each piece of original message X as a root node, generating a piece of reposted message each time the original message X is reposted, and adding the reposted message to the reposting chain as a sub-node; and pulling needed reposted messages from the server when a client terminal device, at which a user locates receives an instruction instructing viewing the reposted messages corresponding to the original message X in a full amount message aggregation mode, and displaying the reposted messages on a page. Embodiments of the present invention also provide a system for presenting reposted messages. With the scheme of the present invention, a whole reposting chain of the original message may be presented to the user.

Abstract: The present invention is applied to the field of computer network communications, and provided are a method and device for achieving data roaming. The method comprises: a client obtaining a data roaming voucher uniquely corresponding to user logon information; the client sending a data roaming request with the data roaming voucher to a data roaming server; and according to the data roaming voucher contained in the received data roaming request, the data roaming server verifying whether the data roaming request is valid, and transmitting roaming data between the client and the data roaming server if the data roaming request is valid. Before data communication is conducted between a client and a data roaming server, the step of verifying the validity of a user data roaming request is also required, and thus, the present invention can achieve the secure isolation of user information.

Abstract: The disclosure provides a login method, an open platform identification method, an open platform and an open platform system. A user terminal is guided to agree to authorize a third party application via a page of the open platform; when the connection of authorization of the user terminal succeeds, the open platform brings a first OpenID and a first OpenKey of the user to the third party application according to a login rebound protocol of the open platform; then the third party application performs user-terminal-based authorized login according to the first OpenID and the first OpenKey; and when the user terminal logging into the open platform initiates the third party application, a prompt message is sent to the user terminal with an open platform account serving as an identification of the open platform, and thus login can be implemented in various forms.

Abstract: The invention discloses a method and a device for updating messages, which belong to the technical field of microblog technology. The method comprises: acquiring message indexes from a microblog server when a user requests updating messages; determining K message indexes as message indexes of the messages for initial message display from the acquired message indexes according to the preset number K, acquiring the corresponding messages from the microblog server according to the message indexes of the messages for initial message display and displaying the corresponding messages to the user; wherein K is a natural number. The device comprises: an acquisition module and an initial display module. The invention reduces the load on the microblog server, avoids resources waste at the client and improves the user's experience.
