Abstract

The invention discloses a data query method, device and system, relates to the field of telecommunication technology and aims to solve the problem of non-correspondence, caused by delay, between a query result and query operation. The method comprises the steps that an unrepeatable request mark is generated for a query request to be sent; the query request carrying the request mark is sent to a server; a query response returned by the server is received, wherein the query response carries query data and the request mark carried by the query request corresponding to the query response; whether the received request mark is the same as the request mark carried by the query request sent the last time or not is judged; if the judgment result is yes, the query data is output. The data query method, device and system are mainly applied to the data query process based on an HTTP.

Description

technical field [0001] The present invention relates to the technical field of telecommunication, in particular to a data query method, device and system. Background technique [0002] Data query is the most basic means of data interaction in modern Internet technology, and it is widely used in browser applications and database query systems. A typical data query process involves both the client as the query initiator and the server as the query responder. The client initiates a query request, adds query conditions (such as the address of the host to be accessed) to the query request and sends it to the server. The server parses the content of the query request, performs data query according to the query condition, and returns the query result (such as webpage data) to the client by returning a query response. [0003] In the existing data query process, the inventor found that: when the client initiates multiple query requests in a short period of time, affected by variou...
