Download the PHP package xcl3721/dora-rpc without Composer

On this page you can find all versions of the php package xcl3721/dora-rpc. It is possible to download/install these versions without Composer. Possible dependencies are resolved automatically.

FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Please rate this library. Is it a good library?

简介(Introduction)

Dora RPC 是一款基础于Swoole定长包头通讯协议的最精简的RPC, 用于复杂项目前后端分离，分离后项目都通过API工作可更好的跟踪、升级、维护及管理。

问题提交: Issue

For complex projects separation, the project can be better maintained by the API project management.

  • Dora RPC is an Basic Swoole Fixed Header TCP Proctol tiny RPC
  • Now support an simple PHP version
  • If you find something wrong,please submit an issue
  • add the http protocol and KeepAlive for the other program language

设计思路(Design)

功能支持(Function)

  • 支持单API调用，多API并发调用
  • 支持同步调用，异步任务下发不等待结果，异步任务下发统一拿回结果
  • 其他相关知识请参考Swoole扩展
  • 客户端长链接，请求完毕后仍旧保留，减少握手消耗
  • guid收发一致性检测，避免发送和接收数据不一致

  • 基于redis制作的服务发现

  • Single API RPC \ Multi API Concurrent RPC
  • Asynchronous，synchronization no need result， synchronization get result by manual
  • Please visit Swoole official for further infomation
  • keep the connection of client after the request finishe
  • check the guid when the send<->recive
  • service discovery.
  • base on Redis. Service discovery for High available

请安装依赖(depend)

  • Swoole 1.8.x+
  • PHP 5.4+
  • zlib for compress packet

Installation

文件功能简介(File)

dora-rpc/src/Client.php

  • 使用最简单的方式实现的客户端，通过这个框架可以轻松实现PHP的伪多线程，通过分布式加快接口响应速度及高可用
  • an simple client,it's easy adn simply to implement the multi fake thread,you can speed up you API by this distribute RPC

dora-rpc/src/BackEndServer.php

  • API服务端
  • 目前需要继承才能使用，继承后请实现dowork，这个函数是实际处理任务的函数参数为提交参数
  • 做这个只是为了减少大家启用RPC的开发时间
  • 开启服务发现功能，服务端在启动的时候，如果指定redis配置则会自动将当前服务器信息注册到Redis上

  • 返回结果是一个数组 分两部分，第一层是通讯状态code，第二层是处理状态 code

  • a powerful API server
  • you must extends the swserver and implement dowork function
  • it's use for decrease the dev cycle
  • when you setup the redis config the server will register this server to the redis for service discovery
  • the result will be a two-level arrayfirst is communicate state 'code field' ,second is dowork state

dora-rpc/src/Monitor.php

  • 服务发现客户端，通过扫描Redis获取到所有可用后端服务列表，并生成配置到指定路径
  • an discovery controller client that:scan all the redis and get the list of available service and general config file to special path

dora-rpc/src/groupclient.php (combined to client.php)

  • 服务发现monitor进程产生的配置可以用这个客户端直接引用，请求时可以指定使用哪个组的服务
  • an client for service discovery （monitor general the config from redis） that you can use the config directly

使用方法(Example)

任务下发模式介绍(task deploy mode)

  • 0 sync wait result 同步下发任务阻塞等待结果返回
  • 1 async no need result 下发异步任务，下发成功返回下发成功提示，不等待任务处理结果
  • 2 async get result by getAsyncData function 下发异步任务，下发成功返回下发成功提示，可以在后续调用getAsyncData 获取所有下发的异步结果

TCP客户端(TCP Client)

HTTP客户端(Http Client)

http protocol for the other language use performance is common.suggest used tcp client

服务端(Server)

客户端监控器(Client Local Monitor)

以上代码测试方法

include以上两个文件，使用命令行启动即可（客户端支持在apache nginx fpm内执行，服务端只支持命令行启动）

  • php democlient.php
  • php demoserver.php

错误码及含义(Error Code)

  • 0 Success work
  • 100001 async task success
  • 100002 unknow task type
  • 100003 you must fill the api parameter on you request
  • 100005 Signed check error
  • 100006 Pack decode type wrong
  • 100007 socket error the recive packet length is wrong
  • 100008 the return guid wrong may be the socket trasfer wrong data
  • 100009 the recive wrong or timeout
  • 100010 there is no server can connect
  • 100011 unknow cmd of controlle
  • 100012 Get Async Result Fail: Client Closed.
  • 100099 unknow communicate mode have been set
  • 100100 guid wront please retry..

性能(Performance)

  • Mac I7 Intel 2.2Mhz
  • Vagrant with Vm 1 Core
  • 1G Memory
  • with example code (loop forever)

测试结果Result

  • Network Cost:0.002~0.004/sec Per Request
  • CPU 10~25% 以上还有很大优化空间 There is still a lot of optimization space
