什么是OSharp
OSharpNS全称OSharp Framework with .NetStandard2.0,是一个基于.NetStandard2.0开发的一个.NetCore快速开发框架。这个框架使用最新稳定版的.NetCore SDK(当前是.NET Core 2.2),对 AspNetCore 的配置、依赖注入、日志、缓存、实体框架、Mvc(WebApi)、身份认证、权限授权等模块进行更高一级的自动化封装,并规范了一套业务实现的代码结构与操作流程,使 .Net Core 框架更易于应用到实际项目开发中。

概述
前后端分离的系统中,前端和后端只有必要的数据通信交互,前端相当于一个完整的客户端应用程序,需要包含如下几个方面:
- 各个模块的布局组合
- 各个页面的路由连接
- 业务功能的数据展现和操作流程体现
- 操作界面的菜单/按钮权限控制
OSharp的Angular前端是基于 NG-ALAIN 框架的,这个框架基于阿里的 NG-ZORRO 封装了很多方便实用的组件,让我们很方便的实现自己需要的前端界面布局。
前端业务模块代码布局
在Angular应用程序中,存在着模块module的组织形式,一个后端的模块正好可以对应着前端的一个module。
博客模块涉及的代码文件布局如下:
src 源代码文件夹
└─app APP文件夹
└─routes 路由文件夹
└─blogs 博客模块文件夹
├─blogs.module.ts 博客模块文件
├─blogs.routing.ts 博客模块路由文件
├─blog 博客组件文件夹
│ ├─blog.component.html 博客组件模板文件
│ └─blog.component.ts 博客组件文件
└─post 文章组件文件夹
├─post.component.html 文章组件模板文件
└─post.component.ts 文章组件文件
业务组件
组件Component是Angular应用程序的最小组织单元,是完成数据展现和业务操作的基本场所。
一个组件通常包含 组件类 和 组件模板 两个部分,如需要,还可包含 组件样式。
STComponentBase
为方便实现各个数据实体的通用管理列表,OSharp定义了一个通用列表组件基类 STComponentBase,基于这个基类,只需要传入几个关键的配置信息,即可很方便的实现一个后台管理的实体列表信息。STComponentBase主要特点如下:
- 使用了 NG-ALAIN 的 STComponent 实现数据表格
- 使用 SFComponent + NzModalComponent 实现数据的
添加/编辑 操作
- 封装了一个通用的高级查询组件
AdSearchComponent,可以很方便实现数据的多条件/条件组无级嵌套数据查询功能
- 对列表组件进行统一的界面布局,使各列表风格一致
- 提供了对列表数据的
读取/添加/编辑/删除 的默认实现
- 极易扩展其他表格功能
STComponentBase 代码实现如下:
export abstract class STComponentBase {
moduleName: string;
// URL
readUrl: string;
createUrl: string;
updateUrl: string;
deleteUrl: string;
// 表格属性
columns: STColumn[];
request: PageRequest;
req: STReq;
res: STRes;
page: STPage;
@ViewChild('st') st: STComponent;
// 编辑属性
schema: SFSchema;
ui: SFUISchema;
editRow: STData;
editTitle = '编辑';
@ViewChild('modal') editModal: NzModalComponent;

STComponentBase 基类的使用很简单,只需重写关键的 GetSTColumns 方法传入实体的列选项,即可完成一个管理列表的数据读取,查询,更新,删除等操作。
