新老客户大回馈,云服务器低至5折

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>
    <table>约束</table>
    <table>
        <thead>
            <tr>
                <th>
                    约束
                </th>
                <th>
                    描述
                </th>
                <th>
                    表达
                </th>
                <th>
                    样例
                </th>
            </tr>
        </thead>
        <tbody>
            <tr>
                <td>alpha</td>
                <td>匹配大写或小写拉丁字母字符 (a-z、a-z)</td>
                <td>{x:alpha}</td>
                <td><a href="/alphaConstraint/foo">成功</a><a href="/alphaConstraint/1">失败</a></td>
            </tr>
            <tr>
                <td>bool</td>
                <td>匹配布尔值</td>

                <td><a href="/boolConstraint/true">成功</a><a href="/boolConstraint/foo">失败</a></td>
            </tr>
            <tr>
                <td>datetime</td>
                <td>匹配<strong>时间</strong>值</td>

            <tr>
                <td>decimal</td>
                <td>匹配十进制值</td>
                <td>{x:decimal}</td>

            </tr>
            <tr>

            </tr>
            <tr>
                <td>int</td>
                <td>匹配整数值</td>
                <td>{x:int}</td>
                <td><a href="/intConstraint/1">成功</a><a href="/intConstraint/foo">失败</a></td>
            </tr>
            <tr>
                <td>length</td>
                <td>与指定长度或指定范围内的字符串匹配</td>

                <td><a href="/lengthConstraint/foobar">成功</a><a href="lengthConstraint/foobarfoobarfoobar">失败</a></td>
            </tr>
            <tr>
                <td>max</td>
                <td>匹配具有最大值的整数</td>
                <td>{x:max(6)}</td>
                <td><a href="/maxConstraint/5">成功</a><a href="/maxConstraint/20">失败</a></td>
            </tr>
            <tr>
                <td>maxlength</td>
                <td>匹配最大长度的字符串</td>
                <td>{x:maxlength(10)}</td>
                <td><a href="/maxlengthConstraint/foobar">成功</a><a href="/maxlengthConstraint/foobarfoobar">失败</a></td>
            </tr>
            <tr>

                <td><a href="/minConstraint/5">成功</a><a href="/minConstraint/2">失败</a></td>
            </tr>
            <tr>
                <td>minlength</td>
                <td>匹配最小长度的字符串</td>
                <td>{x:minlength(4)}</td>

            </tr>
            <tr>
                <td>range</td>
                <td>匹配值范围内的整数</td>
                <td>{x:range(10,20)}</td>

            </tr>
            <tr>
                <td>version</td>

                <td>{x:version}</td>
                <td><a href="/versionConstraint/3.2.1">成功</a><a href="/versionConstraint/-4">失败</a></td>
            </tr>
            <tr>
                <td>email</td>
                <td>匹配电子邮件地址</td>
                <td>{x:email}</td>
                <td><a href="/emailConstraint/mail@domain.com">成功过</a><a href="emailConstraint/maild@asdsacom">失败</a></td>
            </tr>
        </tbody>
    </table>
</body>
</html>

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!
