FlowMaker
FlowMaker是一个基于.NET8的流程编辑执行框架
为您提供简洁API, 方便的中间件开发体验
流程
FlowManager,可进行初始化,执行,停止,发送事件等操作。
IFlowProvider,可以对流程序列进行保存和读取。
步骤
- 无参数步骤
public partial class MyClass : IStep
{
public static string Category => "类别";
public static string Name => "名称";
public Task Run(StepContext stepContext, CancellationToken cancellationToken)
{
throw new NotImplementedException();
}
}
//注册相关步骤
hostApplicationBuilder.Services.AddFlowStep<MyClass>();
- 有输入输出的步骤
public partial class MyClass : IStep
{
public static string Category => "Test1";
public static string Name => "输入输出各一个";
[Input]
public int Input { get; set; }
[Output]
public int Output { get; set; }
public Task Run( StepContext stepContext, CancellationToken cancellationToken)
{
Output = Input * 2;
return Task.CompletedTask;
}
}
输入参数可以添加多种特性标签
[DefaultValue("3")]
[Description("属性2")]
[Option("三", "3")]
[Option("四", "4")]
public int Prop2 { get; set; }
- 将整个类转换为步骤,上下文和取消令牌分别为第一个参数与最后一个参数,如果不需要可以不填写。
[Steps("Category")]
public class AllStepMode
{
[Description("算法A")]//通过特性标签改变显示名称
public (int, string) Test(int ss = 3, CancellationToken cancellationToken = default)
{
return (ss, "ss");
}
public int Test2(StepContext stepContext, DayOfWeek ss, CancellationToken cancellationToken)
{
return 1;
}
}
//注册相关步骤
hostApplicationBuilder.Services.AddScoped<AllStepMode>();
hostApplicationBuilder.Services.AddAllStepModeFlowStep();
- 将接口转换为步骤,与将整个类转换为步骤类似,但是输入中会多出配置具体实现的参数。
[Steps("FFF")]
public interface ITestStep
{
Task<int> Test(StepContext stepContext, int ss = 2);
}
//注册相关步骤
hostApplicationBuilder.Services.AddITestStepFlowStep();
hostApplicationBuilder.Services.AddKeyedScoped<ITestStep, TestStep1>("Test1");
hostApplicationBuilder.Services.AddKeyedScoped<ITestStep, TestStep2>("Test2");
//配置选项
hostApplicationBuilder.Services.Configure<ITestStepInstanceOption>(c =>
{
c.Instances.Add(new FlowMaker.NameValue("Test1", "Test1"));
c.Instances.Add(new FlowMaker.NameValue("Test2", "Test2"));
});
- 选项提供类,提供可变化的参数选项下拉框
public partial class PortProvider : IOptionProvider<string>
{
public static string DisplayName => "串口";
public async Task<IEnumerable<NameValue>> GetOptions()
{
await Task.CompletedTask;
return [new("oo", "22"), new("oo22", "2211")];
}
}
//注册选项提供类
hostApplicationBuilder.Services.AddFlowOption<PortProvider>();
转换器
配置流程时可以对输入输出的信息进行加工,此时需要用到转换器,实现方式于步骤类似,但是根据转换器的类型有固定的返回类型
public partial class ValueConverter : IDataConverter<int>
{
public static string Category => "Test1";
public static string Name => "转换器1";
[Input]
public int Prop1 { get; set; }
[Input]
public int Prop2 { get; set; }
public Task<int> Convert(FlowContext? context, CancellationToken cancellationToken)
{
return Task.FromResult(Prop1 + Prop2);
}
}
//注册转换器
hostApplicationBuilder.Services.AddFlowConverter<ValueConverter>();
中间件
提供了5种中间件
- IFlowMiddleware 流程的开始与结束
- IStepMiddleware 步骤的开始与结束
- IStepOnceMiddleware 步骤的单次执行时的开始与结束(如重复与重试)
- IEventMiddleware 事件触发时
- ILogMiddleware 记录日志时
public interface IFlowMiddleware
{
Task OnExecuting(FlowContext flowContext, FlowState runnerState, CancellationToken cancellationToken);
Task OnExecuted(FlowContext flowContext, FlowState runnerState, Exception? exception, CancellationToken cancellationToken);
}
public interface IStepMiddleware
{
Task OnExecuting(FlowContext flowContext, FlowStep flowStep, StepStatus step, CancellationToken cancellationToken);
Task OnExecuted(FlowContext flowContext, FlowStep flowStep, StepStatus step, Exception? exception, CancellationToken cancellationToken);
}
public interface IStepOnceMiddleware
{
Task OnExecuting(FlowContext flowContext, FlowStep flowStep, StepStatus step, StepOnceStatus stepOnceStatus, CancellationToken cancellationToken);
Task OnExecuted(FlowContext flowContext, FlowStep flowStep, StepStatus step, StepOnceStatus stepOnceStatus, Exception? exception, CancellationToken cancellationToken);
}
public interface IEventMiddleware
{
Task OnExecuting(FlowContext flowContext, string eventName, string? eventData, CancellationToken cancellationToken);
}
public interface ILogMiddleware
{
Task OnLog(FlowContext flowContext, FlowStep flowStep, StepStatus step, StepOnceStatus stepOnceStatus, LogInfo logInfo, CancellationToken cancellationToken);
}
待完善内容
- 对一个类中的方法生成为步骤,可以使用Scope域实现一个流程过程中的状态保持。自动解析输入输出参数
- 方法生成步骤是需要匹配参数, 将FlowContext等加进去.
- 从代码备注中获取更多信息
- 对接口生成的步骤添加可选实例的参数
- 实现流程内的分组功能
- 子流程的日志问题
- 对日志进行分类显示与保存
- 优化流程编辑方式
- 优化代码编辑流程的API(需要设置项过多,延后)
- 完善文档
- 测试
