该项目包括</span> 非死book使用</span></span></span>的</span></span></span></span></span>核心</span> C++抽象HTTP。在内部，它被用作</span>构建HTTP服务器，代理服务器和客户端</span></span>的基础库。本次发布的重点是常见的HTTP抽象和简单的HttpServer框架。未来版本将提供简单的客户端API。该框架支持HTTP/1.1，SPDY/3，和SPDY/3.1。 HTTP /2支持正在进行中。我们的目标是提供一个简单，高性能，以及现代的C++ HTTP库。

目录结构和内容：

• proxygen/external/ Contains non-installed 3rd-party code proxygen depends on.
• proxygen/lib/ Core networking abstractions.
• proxygen/lib/http/ HTTP specific code.
• proxygen/lib/services/ Connection management and server code.
• proxygen/lib/ssl/ TLS abstractions and OpenSSL wrappers.
• proxygen/lib/utils/ Miscellaneous helper code.
• proxygen/httpserver/ Contains code wrapping proxygen/lib/ for building simple C++ http servers. We recommend building on top of these APIs.

架构

基础组件是HTTPServer, RequestHandlerFactory, 和 RequestHandler。An HTTPServer takes some configuration and is given aRequestHandlerFactory. Once the server is started, the installedRequestHandlerFactory spawns a RequestHandler for each HTTP request. RequestHandler is a simple interface users of the library implement. Subclasses of RequestHandler should use the inherited protected member ResponseHandler* downstream_ to send the response.
