基于AJAX的数据跨域传输技术分析

Research on AJAX-based Data Cross-domain Transmission Technology

随着大数据和Internet的快速发展,出现了大规模的分布式Web系统,浏览器端Script代码跨域进行数据传输时与浏览器端Script的同源策略相冲突。实现浏览器端Script代码实现跨域交换数据的同源策略限制需要选择合适的解决方案。通过分析同源策略限制,结合几种实现数据传输技术路线,为分布式跨域数据传输的多种场景提供了较多灵活的解决方案。

With the rapid development of big data and the Internet, a large-scale distributed Web system has emerged. The browser-side script code conflicts with the browser-side script’s same-origin policy when transmitting data across domains. Breaking the restriction in the transmission requires choosing an appropriate solution. By analyzing the same-origin policy restriction and combining several technical routes, this paper provides more flexible solutions for a variety of different scenarios of distributed cross-domain data transmission.
