Thrift - 结合阅读 http 和原始处理

技术标签:
【中文标题】Thrift - 结合阅读 http 和原始处理【英文标题】:Thrift - combine reading http and raw processing 【发布时间】:2015-04-13 06:18:17 【问题描述】:我正在查看Thrift's tutorial example。我正在尝试创建一个处理原始节俭请求(原始)和 javascript 请求(http)的服务器。
java 服务器直接从套接字读取 - new TServerSocket(9090) - 使用 thrift 的协议处理请求。
不过,javascript 示例需要一个 http 服务器 (Httpd.java)。我在下载的源代码中找到了它。见下文。
两者处理传入字节的方式不同。 如何将这两种处理结合起来?拥有快速的原始处理,结合用于读取浏览器请求的 http 处理?

【问题讨论】:
这个 Httpd 服务器太棒了。它提供静态页面(作为 GET)以及 Thrift 处理。 【参考方案1】:一种方法是使用不同的端口。
例如,在教程示例中,端口 8088 可以绑定到 HTTP,而端口 9090 可以绑定到套接字传输。
如果我想使用不同的传输,我会在不同的端口处理它。
** 令人惊讶的是,我只有在提交问题后才会想到答案。有没有办法在我的脑海中提交一个问题以更快地得到答案?至少社区喜欢我的大脑;)
【讨论】:
不加http处理,没看到其他办法。以上是关于Thrift - 结合阅读 http 和原始处理的主要内容,如果未能解决你的问题,请参考以下文章
