Abstract

The invention discloses a data acquisition method, a server and a related system, and the method comprises the steps of judging whether a client task of the client task is a main process for acquiringdata from a third-party server or not after the client task of the client task is started, wherein the main process is a unique process capable of acquiring data from the third-party server at the current moment; when the judgment result is yes, connecting the third-party server and requesting to acquire data; when each data message arrives, judging whether a client task of the client is still the main process or not; and if so, acquiring and processing the data. According to the data acquisition method disclosed by the invention, the single-point problem existing in the prior art can be avoided by scheduling the client task in each server, and the timely acquisition of real-time data can be ensured when a machine crashes, a network fault or other problems influencing connection occur.

Description

Technical field [0001] The present invention relates to the field of data processing technology, in particular to a data acquisition method, server and related systems. Background technique [0002] In the prior art, navigation service providers that provide navigation services generally obtain data (such as real-time bus data, real-time traffic flow data, etc.) from the data provider's server (also called a third-party server). Take data as an example. One is that the navigation server itself acts as the server and the real-time bus data provider acts as the client to receive data from the client; the other is that the navigation service itself acts as the client to provide real-time bus data. The provider is the server, and the navigation service party actively connects to the server to receive data. [0003] Among them, in the latter way, in the case of receiving data as a client, since the server will synchronize a real-time bus data for each connected client, the current comm...
