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.

- 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.

注册异常处理器
在rpc接口服务配置下新增 Ericjank\Htcc\Exception\Handler\TransactionException::class
例如：
在需要进行事务处理的第一个方法体添加注解
- try try阶段执行的方法名, 如不指定try则该接口全部方法在本次事务中如有调用都进行事务处理
- onConfirm confirm阶段执行的方法名
- onCancel cancel阶段执行的方法名
- clients 当前事务需要监控的接口, 不是过程中所有的接口都需要事务处理, 方法中使用的不需要事务处理的接口不必配置到监控列表里
- service 接口消费者类
如未设置confirm和cancel方法 则默认以调用方法开头以Confirm或Cancel作为方法后缀自动调用
实现try, confirm,cancel方法
被调用端接口需实现try, confirm,cancel方法， 方法内如发生错误需要抛出 Ericjank\Htcc\Exception\RpcTransactionException 异常 , 才能被上层接口捕获并进行相应的处理 为了不影响接口自身在非事务情况下的使用(或者说兼容事务与非事务两种情况)，可以使用 inRpcTrans() 方法判断当前是否在rpc事务中，仅在事务中抛出 RpcTransactionException 异常，其他情况则按照原有流程正常执行即可;
也可以用函数 rpcTransCallback 进行简化处理
使用 Ericjank\Htcc\Catcher 处理分布式事务防悬挂、空回滚等问题
try 阶段
通过注入 Ericjank\Htcc\Catcher 获取对象 $this->catcher
confirm 阶段
cancel 阶段
函数
- getRpcTransID 获取当前事务ID(支持在事务发起端和远程接口)
- inRpcTrans 检测是否在事务中
- rpcTransCallback
- hasRpcTransError 获取事务抛出的错误信息(支持在事务发起端和远程接口的try方法内)
- getRpcTransSteps 获取事务流程数据(支持在事务发起端)
