摘　　要：随着HTML5技术的逐渐普及,基于网页技术的应用开始逐渐发展壮大。与此同时,针对支持Web应用的引擎技术也在日臻完善。本文提出了一种基于命名管道的IPC通信机制,用于基于Chromium架构的嵌入式Web应用引擎当中。与Chromium架构中原有的机制相比,该方式能够实现Web应用引擎中非父子进程间的间接通信,丰富了Web引擎中的进程间的访问方式。本文首先简要介绍了基于Chromium架构的嵌入式Web应用引擎的主要的关键技术(包括多进程、多线程机制以及在此基础上的原有IPC通信机制等等),然后详细描述和分析了所提出的基于命名管道的IPC通信结构。最后,在嵌入式Web应用引擎环境下实验验证了新的IPC方案的有效性。With the gradual popularization of HTML5 technology,applications based on web technologies have gradually grown.At the same time,engine technologies for supporting Web applications are also being improved.This paper proposes an IPC communication mechanism based on named pipes for Chromium-based embedded Web application engine.Compared with the original mechanism in the Chromium architecture,this method can realize indirect communication between non-parent and child processes in the web application engine,thus enriching the Web engine’s access methods between processes.This paper first introduces the key technologies of Chromium-based embedded Web application engine(including multi-process,multi-threading mechanism and the original IPC communication mechanism in Chromium),and then describes and analyzes our proposed IPC communication structure based on named pipes.Finally,we validated the effectiveness of the new IPC scheme in the embedded Web application engine environment.
