新建一个空的Web项目
然后在Nuget库中安装下面两个包
- Nancy
- Nancy.Hosting.Aspnet
然后在根目录添加三个文件夹，分别是models，Module，Views
然后往Module文件夹里面添加ConstraintRoutingModule类
public ConstraintRoutingModule() { Get("/",Lexan=>View["index"]); Get("/intConstraint/{value:int}",Lexan=>"这个值"+Lexan.value+ "是整数"); Get("/decimalConstraint/{value:decimal}",Lexan=>"这个值"+ Lexan.value+ "是十进制"); Get("/guidConstraint/{value:guid}",Lexan=>"这个值"+Lexan.value+ "是 guid"); Get("/boolConstraint/{value:bool}",Lexan=>"这个值"+Lexan.value+"是布尔值"); Get("/alphaConstraint/{value:alpha}", Lexan => "这个值" + Lexan.value + "是是信件"); Get("/datetimeConstraint/{value:datetime}", Lexan => "这个值" + Lexan.value + "是日期时间"); Get("/customDatetimeConstraint/{value:datetime(yyyy-MM-dd)}", Lexan => "这个值" + Lexan.value + "是一个日期时间, 格式为 'yyyy - mm - dd' "); Get("/minConstraint/{value:min(4)}", Lexan => "这个值" + Lexan.value + "是大于4的整数"); Get("/maxConstraint/{value:max(6)}", Lexan => "这个值" + Lexan.value + "是小于6的整数"); Get("/rangeConstraint/{value:range(10,20)}", Lexan => "这个值" + Lexan.value + "是介于10和20之间的整数"); Get("/minlengthConstraint/{value:minlength(4)}", Lexan => "这个值" + Lexan.value + "长度大于4的字符串"); Get("/maxlengthConstraint/{value:maxlength(10)}", Lexan => "这个值" + Lexan.value + "长度小于10的字符串"); Get("/lengthConstraint/{value:length(1,20)}", Lexan => "这个值" + Lexan.value + "是长度介于1和20之间的字符串"); Get("/versionConstraint/{value:version}", Lexan => "这个值" + Lexan.value + "是版本号"); Get("/emailConstraint/{value:email}", Lexan => "这个值" + Lexan.value + "是一个电子邮件地址"); }
然后往Models文件夹里面添加EmailRouteSegmentConstraint类
public override string Name { get { return "email"; } } protected override bool TryMatch(string constraint, string segment, out string matchedValue) { //throw new NotImplementedException(); //使用 @jchannon 逻辑验证电子邮件地址 if (segment.Contains("@")&&segment.Contains(".")) { matchedValue = segment; return true; } matchedValue = null; return false; }
然后往Views文件夹里面添加index的html页面
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title></title>
<style>
table {
border-collapse:collapse;
}
table,th,td{
border:1px solid black;
padding:2px 3px;
}
</style>
</head>
<body>
<h1>约束路由</h1>

然后修改Web.config配置文件
<httpHandlers>
<add verb="*" type="Nancy.Hosting.Aspnet.NancyHttpRequestHandler" path="*" />
</httpHandlers>
</system.web>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true" />
<validation validateIntegratedModeConfiguration="false" />
<handlers>
<add name="Nancy" verb="*" type="Nancy.Hosting.Aspnet.NancyHttpRequestHandler" path="*" />
</handlers>
</system.webServer>
然后按下F5运行
谢谢欣赏！明天同一时间更新！
