http-client

本项目是一个高稳定性与高性能的 HTTP 客户端,可在多平台使用,拥有极简的 API 接口。

整体架构如下:

http-client架构

解析一下整个架构:

  • 最上方是对外的 API 接口。

  • 接着就是 client 管理器,通过池化技术实现了 client pool,在使用的时候从池中取出 client,用完就放回,用户基本不需要直接接触 client 实例,实现了基本的 HTTP 方法,如 GET/POST 等,还实现了 url 解析器,解析用户传入的 url,生成合适的参数递交给拦截器。

  • 实现工作队列,进行异步处理,在 CPU 支持多核的情况下,根据 CPU 的最大支持线程数量创建多个线程处理,将所有来自上层的请求按顺序放入工作队列,并行处理。

  • intercept 是拦截器,比如实现 HTTP请求HTTP应答 等,它需要依赖 HTTP 报文的处理。拦截器的主要的处理工作是通过上层传入的参数去设置网络信息(host、port 等),与服务器建立连接、重连,发起 HTTP 请求、解析来自服务器的响应报文,自动处理重定向及其他操作,而保证这些操作能完成的需要基础组件,通用的字符串处理、事件的回调处理、 HTTP 的通用信息等,最下方的 read and write 则是与 network 打交道的。

  • network 是网络组件,它可以自动选择数据通道,如果是 加密 方式则通过 tls 进行数据传输,而 tls 可以选择 mbedtls 作为加密后端也可以选择 openssl 作为加密后端;也可以是 tcp 直连方式,最终都是通过 tcp 传输的,此外还实现了本地的 routing(或者叫 dns 缓存,加快域名的解析处理)。

  • platform 是平台抽象层,封装了不同系统的东西,比如 socke 或者 AT线程时间互斥锁内存管理,这些是与系统打交道的,也是跨平台必要的封装。

  • 最右边的则是通用的内容,list 列表的处理、日志库错误代码软件随机数发生器 等。

发布版本 描述
[v1.0.0] 初次发布,完成基本架构的及其稳定性验证

文档说明

欢迎各位朋友参与进来开发,所有的功能实现都有详细的文档介绍,大家可以选择 开发计划 中的项目进行开发、探讨、提交PR,也欢迎大家提交功能需求,本项目将由 杰杰 持续维护。

测试代码 & 文档

参与开发

  • 平台:任何 linux 平台,目前先暂时开发 linux 平台的,后续适配其他平台。

安装 cmake 及编译器

sudo apt-get install -y cmake gcc g++

编译

编写好相关的功能后进行编译并测试,main 函数入口在 test/test.c 文件中。

./build.sh

产生的可执行文件在 ./build/bin/http-client 路径下。

运行

 ./build/bin/http-client

观察测试结果,满足要求后提交 PR

如何提交PR?

问题

欢迎以 GitHub Issues 的形式提交功能需求、问题和 bug 报告等。
