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:
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.

Informations about the package syar
为何用swoole来实现 Yar server
- 提升Yar服务效率
- 提升Yar服务稳定性
- 学习swoole, yar(在此感谢laruence,rango及swoole开发团队)
Requirements
- php5.4+
- ext-swoole 1.8.8+
- ext-msgpack 如果yar使用msgpack编码方式
Installation
Example
服务端 example\server.php
example/service/Test.php
命令行启动server.php
客户端
简单性能测试(benchmark)
测试脚本 example/benchmark/testSimple.php, 测试环境(虚拟机)
- cpu: i5 - 4460
- mem: 4G
- os: centos6.5
- php: php7(fpm: 20进程, swoole: 18进程(8 worker + 10 task)
脚本一共完成44次接口调用：
- 简单接口调用 2次
- 数据库查询接口调用2次
- 并发简单接口调用 20次
- 并发数据库查询接口调用 20次
在当前测试环境下，在使用syar批量接口请求，fpm环境下的执行时间大概是syar下的3 -- 6倍左右，
简单压力测试
测试脚本 example/benchmark/testConcurrent.php, 50%接口随机查询数据库(10000条数据, 主要为测试接口通信性能)
- syar 20个并发进程2.4w次接口调用, 用时2.6s秒左右, QPS 9300左右, 可能存在个别调用错误
- fpm 20个并发进程2.4w次接口调用, 用时15s秒左右, QPS 1600左右, 并产生大量Timeout was reached错误
扩展特性
接口批量请求
- 批量请求的接口,服务端使用多个任务进程并行执行
- 请求地址 http://{your_server_address}/multiple
- 调用方法名 function calls($requests); $requests参数格式 [请求1数组, 请求2数组, ...], 请求数据格式：['api' => ApiName, 'method' => MethodName, 'params' => []]
- 单个接口执行错误, 服务端记录错误日志, 返回['code' => CODE, 'error' => ERROR MESSAGE]格式数组, 客户端自行处理
客户端请求示例：
Protocol插件与Dispatcher插件
应用示例参考 example/server_plug.php, client_plug.php
Protocol触发事件：
- Protocol::EVENT_REQUEST_BEFORE, 请求开始触发, 可以提前响应客户端， 中断正常解析流程
- Protocol::EVENT_RESPONSE_AFTER, 请求结束触发, 可以适用请求结束之后的处理工作，比如写日志等
Dispatcher触发事件：
- Dispatcher::EVENT_REQUEST_BEFORE, Api接口执行前触发
- Dispatcher::EVENT_REQUEST_AFTER, Api接口执行后触发
投递任务到task进程异步执行
应用示例参考 example/taskManagerServer.php
- TaskMananger->regTask()
- TaskMananger->doTask()
- TaskMananger->doTasks()
- TaskMananger->doTasksAsync()
已知问题
- 未完成文档解析， 可使用自带的yar server显示文档
- 由于代码是从私有框架独立出来，可能存在未知bug
