• 自动ping博客服务程序


    几个月前写了一个博客自动ping程序,其实也没有什么技术含量,只是不想很快被遗忘,在此一记,希望各路好友,批评批正。

    ping程序的,用处是把发布文章主动的提交搜索引擎,以便达到让搜索引擎快速收录。

    程序原理主要通过RPC协议来实现的,下面简单学习一下RPC协议。

    RPC协议

     

      英文原义:Remote Procedure Call Protocol

     

      中文释义:(RFC-1831)远程调用协议

     

      注解:一种通过网络从远程计算机程序上请求服务,而不需要了解底层网络技术的协议。

     

      RPC协议假定某些传输协议的存在,如TCP或UDP,为通信程序之间携带信息数据。在OSI网络通信模型中,RPC跨越了传输层和应用层。RPC使得开发包括网络分布式多程序在内的应用程序更加容易。

     

      RPC采用客户机/服务器模式。请求程序就是一个客户机,而服务提供程序就是一个服务器。首先,调用进程发送一个有进程参数的调用信息到服务进程,然后等待应答信息。在服务器端,进程保持睡眠状态直到调用信息的到达为止。当一个调用信息到达,服务器获得进程参数,计算结果,发送答复信息,然后等待下一个调用信息,最后,客户端调用过程接收答复信息,获得进程结果,然后调用执行继续进行。

    程序主界面载图

    废话少说了,看代码。ping程序内部核心代码都在这里了。
