Abstract
The present application relates to a data acquisition method and device. The method includes: for multiple clients that successfully establish communication links with a server based on an epoll mechanism, the edge trigger mode of the epoll mechanism is turned on to monitor the link status of each communication link, and when the link status of any current communication link is monitored to change, the acquisition file descriptor associated with the current communication link is obtained, and if the data on the acquisition file descriptor is readable, the acquisition file descriptor is added to a ready queue, and the data on each acquisition file descriptor is collected according to the task type in the multiple acquisition file descriptors contained in the queue, and the data acquisition task type priority list. By pre-setting the data acquisition task type priority list, the data acquisition tasks are processed in sequence according to the priority information corresponding to each task type on the list, so as to achieve low latency of data acquisition, thereby improving the acquisition efficiency of data acquisition.
