### Pull Requests

1. Fork the repository
2. Create a new branch for each feature or improvement
3. Send a pull request from each feature branch against the dev branch.

It is very important to separate new features or improvements into separate feature branches, and to send a
pull request for each branch. This allows each feature or improvement to be reviewed and merged individually.

### Coding Style

All pull requests and commits **must** adhere to the [PSR-2 standard](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-2-coding-style-guide.md) at least.  
And we **recommend** adhering to the [PSR-12 standard](https://github.com/php-fig/fig-standards/blob/master/proposed/extended-coding-style-guide.md).

### Commit message

The Commit message must concisely contain all your changes.  
Please **do not** use words like "fix", "improve" only.    
Please try to use **English** in the Commit message and use the following Type tags.
- feat: add or modify a feature (feature)
- fix: fix bugs (bug fix)
- docs: documents (documentation)
- style: formatting    
        changes that do not affect the operation of the code, e.g. white-space, formatting, missing semicolons
- refactor: refactoring    
        Code changes that do not add features or fix bugs
- perf: improves performance
- test: when adding missing tests
- chore: maintenance    
        Changes to builders or helpers that do not affect the operation of the code, e.g., changes to config, Grunt Task management tools
- revert: undo a previous commit    
        Example: revert: type(scope):subject

### Rule

If you want to add a new function for router callback, please follow the structure of the HomeController.  
Please use the function from PSR-7 like `$request->getParsedBodyParam()`, `getParsedBodyParam()` as possible.

## 简体中文

### Pull Request

1. Fork 本项目
2. 为每一项新特性或改进创建一个新的分支
3. 为每一项新特性或改进创建一个独立的 Pull Request 至 dev 分支

我们建议你将不同的新特性置于不同的分支并以不同的 Pull Request 提交，这将有利于我们独立审查代码并独立合并。

### 代码风格

所有的 Pull request 和 commit 都至少**必须**遵守 [PSR-2 标准](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-2-coding-style-guide.md)。  
我们建议**最好**遵守 [PSR-12 标准](https://github.com/php-fig/fig-standards/blob/master/proposed/extended-coding-style-guide.md)。

### Commit 消息

Commit 消息必须简洁地包含你所有的修改。请**不要**仅使用「修复」、「改进」等字样。    
在 Commit 消息中请尽量使用**英文**，并且使用以下 Type 标签：
- feat：新增或修改功能（feature）
- fix：修补 bug（bug fix）
- docs：文件（documentation）
- style：格式    
        不影响程式码运行的变动，例如：white-space, formatting, missing semi colons
- refactor：重构    
        不是新增功能，也非修补 bug 的程式码变动
- perf：改善效能（improves performance）
- test：增加测试（when adding missing tests）
- chore：维护    
        不影响程式码运行，建构程序或辅助工具的变动，例如修改 config、Grunt Task 任务管理工具
- revert：撤销回覆先前的 commit    
        例如：revert：type(scope):subject

### 规范

若你需要新增/修改 Router callback，请依照类似 HomeController 的形式。  
如无必要，请不要使用`$request->getParam()`并尽量使用 PSR-7 中的`$request->getParsedBodyParam()`、`getParsedBodyParam()`等一系列用于获取参数的方法。
