根据特定的规则模型，根据判断表达式判断传入数据集是否符合
- 如果传入规则不存在，默认会判断通过(返回True)
- 表达式默认是以x.开头，x.后面的是传入的数据集的属性名

在 YourProject.EntityFrameworkCore 项目的目录中打开命令行终端，然后键入以下命令：
> dotnet ef migrations add Added_RulesEngine> dotnet ef database updateMVC和Blazor已经实现了维护规则的页面，如果你的项目中没有使用这两个框架，你可以自己实现维护规则的页面
protected IRulesEngineStore rulesEngine => LazyServiceProvider.LazyGetRequiredService<IRulesEngineStore>(); //如下是维护的规则，正式代码下可不用 var input = new Rule { RuleName = "Test1", SuccessEvent = "True", ErrorMessage = "False", ErrorType = default, RuleExpressionType = default, Expression = "x.Name == \"Test\" && x.Age >= 20" }; //TestRule1不存在，会默认返回True var result1 = await _rulesEngineStore.ExecuteRulesAsync("TestRule1", new TestDto(){Name = "Test",Age = 20}); //Test1判断通过返回True var result2 = await _rulesEngineStore.ExecuteRulesAsync("Test1", new TestDto(){Name = "Test",Age = 20}); result2.IsSuccess.ShouldBeTrue(); //Test1判断不通过False var result3 = await _rulesEngineStore.ExecuteRulesAsync("Test1", new TestDto(){Name = "TestRule",Age = 20}); result3.IsSuccess.ShouldBeFalse();//使用规则引擎组 private readonly IRulesGroupsAppService _rulesGroupsAppService; var result1 = await _rulesAppService.VerifyRuleAsync(new VerifyRuleDto() { RuleCode = "TestRule1", ExtraProperties = new ExtraPropertyDictionary()//支持以Dictionary<string,object>传入 { {"Name", "Test"}, {"Age", 20} }, }); //使用规则引擎 private readonly IRulesAppService _rulesAppService; var result1 = await _rulesGroupsAppService.VerifyRulesGroupAsync(new VerifyRuleGroupDto() { GroupName = "TestRule1", ExtraProperties = new ExtraPropertyDictionary()//支持以Dictionary<string,object>传入 { {"Name", "Test"}, {"Age", 20} }, });以电商为例，假设有如下规则
- 1.价格大于1000元满减500元
- 2.价格大于500元满减300元
- 3.价格大于200元满减100元
- 4.价格大于100元满减20元
- 1.可以现在前端判断一次，把结果返回前端
- 2.后端再判断一次，判断前端传入和后端计算结果是否一致 参考代码:JS.Abp.RulesEngine.Blazor.Server.Host/Pages/Books.razor
//判断是否有折扣 var result = await RulesGroupsAppService.VerifyRulesGroupAsync(new VerifyRuleGroupDto() { GroupName = "TestPrice", ExtraProperties = new ExtraPropertyDictionary() { {"Price", BookList.Sum(c=>c.Price)} }, }); if (result.IsSuccess) { if (!result.SuccessEvent.IsNullOrWhiteSpace()) { Discount = result.SuccessEvent; } }
