C# WCF:UriTemplate中的多个可选参数

“我的服务”的模板如下所示：

[WebGet(UriTemplate = "LoginUser/authorizationCode/{authorizationCode}/userId/{userId}/intend/{intend}/email/{email}")]

public User LoginUser(string authorizationCode, string userId, string intend, string email)

函数如下所示：

[WebGet(UriTemplate = "LoginUser/authorizationCode/{authorizationCode}/userId/{userId}/intend/{intend}/email/{email}")]

public User LoginUser(string authorizationCode, string userId, string intend, string email)

我通常的电话是这样的：

[WebGet(UriTemplate = "LoginUser/authorizationCode/{authorizationCode}/userId/{userId}/intend/{intend}/email/{email}")]

public User LoginUser(string authorizationCode, string userId, string intend, string email)

http://localhost:60522/MyService.svc/json/LoginUser/authorizationCode/111222333/userId/0006435cec5aa5640639b5d08314bb989a43519/intend/yyy/email/abc@web.de

我的下一个任务是使intent和email参数可选

因此，我的呼叫必须适用于所有这些变体：

http://localhost:60522/MyService.svc/json/LoginUser/authorizationCode/111222333/userId/0006435cec5aa5640639b5d08314bb989a43519/intend/yyy/email/abc@web.de

http://localhost:60522/MyService.svc/json/LoginUser/authorizationCode/111222333/userId/0006435cec5aa5640639b5d08314bb989a43519/intend/yyy

http://localhost:60522/MyService.svc/json/LoginUser/authorizationCode/111222333/userId/0006435cec5aa5640639b5d08314bb989a43519/email/abc@web.de

http://localhost:60522/MyService.svc/json/LoginUser/authorizationCode/111222333/userId/0006435cec5aa5640639b5d08314bb989a43519

如何编辑模板和函数以使其正常工作？

您可以将intent和email的默认值设置为null，如下所示：

        [OperationContract]
        [WebGet(UriTemplate = "LoginUser/authorizationCode/{authorizationCode}/userId/{userId}/intend/{intend=null}/{email=null}")]
         string LoginUser(string authorizationCode, string userId, string intend, string email);

我们可以通过以下URI访问此服务：

http://localhost:8000/LoginUser/authorizationCode/Test/userId/Test/intend/

http://localhost:8000/LoginUser/authorizationCode/Test/userId/Test/intend/int/

http://localhost:8000/LoginUser/authorizationCode/Test/userId/Test/intend/int/ema/

在这种情况下，如果要设置电子邮件，则必须设置电子邮件地址

因此，我认为最好的方法是分别为它们编写一个接口，如下所示：

        [OperationContract]
        [WebGet(UriTemplate = "LoginUser/authorizationCode/{authorizationCode}/userId/{userId}/intend/{intend}/email/{email}")]
         string LoginUser1(string authorizationCode, string userId, string intend, string email);
        [OperationContract]
        [WebGet(UriTemplate = "LoginUser/authorizationCode/{authorizationCode}/userId/{userId}/intend/{intend}/")]
        string LoginUser2(string authorizationCode, string userId, string intend);
        [OperationContract]
        [WebGet(UriTemplate = "LoginUser/authorizationCode/{authorizationCode}/userId/{userId}/email/{email}")]
        string LoginUser3(string authorizationCode, string userId, string email);
        [OperationContract]
        [WebGet(UriTemplate = "LoginUser/authorizationCode/{authorizationCode}/userId/{userId}/")]
        string LoginUser4(string authorizationCode, string userId);

不同的URI将请求不同的接口
