摘要
本文介绍了一种基于http协议的远程数据采集方法。提出了利用通用网关接口(CGI)进行远程数据采集的观点。论述在CGI程序中与VxD通讯实现数据采集的方法,并与其它方法进行了比较。最后通过实验证明,用CGI进行远程数据采集是确实可行的,并且比传统的方法更为方便实用。
A new method of remote data acquisition based on http is introduced in this article. Common Gateway Interface(CGI) is used in this method. The implementation approach of remote data acquisition using CGI is described and compared with other method. A simple experiment is conducted to prove the method. It is concluded that this new remote data acquisition method using CGI is feasible and more convenient than traditional way.
