Method, device, client and server for interaction

An interaction method, comprising:

• receiving, implemented by a processor of a third-party server, a URL sent from a client;
• sending, implemented by the processor of the third-party server, multifunction interaction information to the client according to the URL, wherein each piece of the multifunction interaction information includes interaction type information that indicating an interaction manner between the client and the third-party server;
• and
• interacting, implemented by the processor of the third-party server, with the client based on the multifunction interaction information,
• wherein the interaction type information indicates one or more members of the group consisting of a system application local to the client, an application developed by the same developer as the client, a webpage application and an APP application developed by a third party,
• wherein when the interaction type information indicates a system application local to the client or an application developed by the same developer as the client, the interacting, implemented by the processor of the third-party server, with the client based on the multifunction interaction information comprising:
• interacting, implemented by the processor of the third-party server, with the indicated type of application locally called by the client by locally calling the same type of application.

A client comprising a processor, the processor functions as:

• a URL acquiring unit, configured to scan a target two-dimensional code and acquire a URL from the target two-dimensional code;
• a URL sending unit, configured to send the URL to a third-party server;
• an information receiving unit, configured to receive multifunction interaction information that is returned from the third-party server according to the URL, wherein each piece of the multifunction interaction information includes interaction type information that indicating an interaction manner between the client and the third-party server;
• and
• an interaction unit, configured to interact with the third-party server based on the multifunction interaction information,
• wherein the interaction type information indicates one or more members of the group consisting of a system application local to the client, an application developed by the same developer as the client, a webpage application and an APP application developed by a third party, and
• wherein the interaction unit is configured to interact with the third-party server by interacting with the indicated type of application locally called by the server by locally calling the same type of application when the interaction type information indicates a system application local to the client or an application developed by the same developer as the client.
