模块定义了一个事件以及一个任务, 事件通过webapi触发
事件触发使用webapi
开发者可以参考更换为其他方式,这里仅供测试
地址http://127.0.0.1:5000/api/demo2/test
DemoController.cs文件内容
using Microsoft.AspNetCore.Authorization;
using Microsoft.AspNetCore.Mvc;
using OrchardCore.Workflows.Services;
using OrchardCoreExample.Workflows.Module.Workflows.Activities;
namespace OrchardCoreExample.Workflows.Module.Controllers
{
[Route("api/demo2/[action]")]
[Authorize(AuthenticationSchemes = "Api"), IgnoreAntiforgeryToken, AllowAnonymous]
[ApiController]
public class DemoController: Controller
{
private readonly IWorkflowManager _workflowManager;
public DemoController(IWorkflowManager workflowManager)
{
_workflowManager = workflowManager;
}
public IActionResult Test()
{
_workflowManager.TriggerEventAsync(nameof(TestEvent), new { json = "工作流测试" });
return Json(new {result = "已经触发工作流事件"});
}
}
}
TestTask.cs文件内根据触发进行操作
using System.Collections.Generic;
using Microsoft.Extensions.Localization;
using OrchardCore.Workflows.Abstractions.Models;
using OrchardCore.Workflows.Activities;
using OrchardCore.Workflows.Models;
namespace OrchardCoreExample.Workflows.Module.Workflows.Activities
{
public class TestTask: TaskActivity
{
private readonly IStringLocalizer<TestTask> S;
public TestTask(IStringLocalizer<TestTask> localizer)
{
S = localizer;
}
public override string Name => nameof(TestTask);
public override LocalizedString DisplayText => S["测试任务"];
public override LocalizedString Category => S["Demo"];
public override IEnumerable<Outcome> GetPossibleOutcomes(WorkflowExecutionContext workflowContext, ActivityContext activityContext)
{
return Outcomes(S["Done"]);
}
public override ActivityExecutionResult Execute(WorkflowExecutionContext workflowContext, ActivityContext activityContext)
{
// 执行任务
// workflowContext.Input 获取事件参数
return Outcomes("Done");
}
}
}
添加一个事件(测试事件)和任务(测试任务)
启用测试事件,并且添加流程线到测试任务
