System for executing prescribed processing in response to message transmission

A server comprising:

• a processor;
• a memory connected to the processor, wherein the memory comprises instructions that, when executed by the processor, are configured to perform a method comprising:
• generating, upon receiving a request information relating to a game campaign from a user via a client terminal, a temporary uniform resource locator (URL) comprising a first identifier and based on campaign identification information,
• wherein the first identifier comprises user identification information for a user, and
• transmitting the temporary URL to the client terminal,
• wherein the client terminal is configured to:
• displays a graphical user interface (GUI) using a game application,
• executes, in response to obtaining a first user input to the GUI from a user, a game campaign using the game application through communication with the server over a network, and
• transmits, in response to obtaining a second user input to the GUI, request information regarding the game campaign to the server over the network,
• wherein the request information comprising a first identifier associated with the user and campaign identification information associated with the game campaign, displaying, within the game application and upon receiving the temporary URL from the server, a screen for selecting a post message function within a social networking service (SNS) application based on the game campaign, and
• transmits, in response to obtaining a third user input to the game application for selecting the post message function, a message to a SNS server configured to display the temporary URL with a thumbnail of the temporary URL, and
• wherein the SNS server is configured to:
• obtain, from the temporary URL and automatically using a crawler and an Open Graph Protocol (OGP) access function in response to receiving the message, OGP information comprising a thumbnail image of the game campaign and a description of the game campaign,
• store the OGP information in a cache in the SNS server, and
• generate the thumbnail of the temporary URL based on the OGP information that is stored in the cache.

A method comprising:

• displaying, by a client terminal using a game application, a graphical user interface (GUI), wherein the client terminal is connected to a game server and a social networking service (SNS) server over a network,
• executing, by the client terminal in response to obtaining a first user input to the GUI from a user, a game campaign using the game application through communication with the game server over the network, and
• transmitting, by the client terminal in response to obtaining a second user input to the GUI, request information regarding the game campaign to the game server over the network,
• wherein the request information comprising a first identifier associated with the user and campaign identification information associated with the game campaign,
• wherein the game server is configured to perform a second method comprising:
• generating, by the game server upon receiving the request information relating to the game campaign from the user via the client terminal, a temporary uniform resource locator (URL) comprising the first identifier and based on the campaign identification information,
• wherein the first identifier comprises user identification information for the user, and
• transmitting, by the game server, the temporary URL to the client terminal,
• displaying, by the client terminal within the game application and upon receiving the temporary URL from the game server, a screen for selecting a post message function within an SNS application based on the game campaign, and
• transmitting, by the client terminal in response to obtaining a third user input to the game application for selecting the post message function, a message to the SNS server configured to display the temporary URL with a thumbnail of the temporary URL, and
• obtaining, by the SNS server from the temporary URL and automatically using a crawler and an Open Graph Protocol (OGP) access function in response to receiving the message, OGP information comprising a thumbnail image of the game campaign and a description of the game campaign,
• storing, by the SNS server, the OGP information in a cache in the SNS server, and
• generating, by the SNS server, the thumbnail of the temporary URL based on the OGP information that is stored in the cache.
