Question

我想使用WCF或Web API在REST中创建登录服务。

使用MVC项目模板，它会为我生成如下服务：

getValues()
getValue(int)
deleteValue(int)
updateValue(int,post)

但是，我希望checkLogin(username, password)之类的服务返回true或false。当前模板只允许我添加标识api/values/5，我无法将其转换为查询字符串api/values/user=123&pass=123，因为它报告路径包含&，这是不安全的。请帮忙。感谢

解决方法如下：（WCF VS-Project）

Public Function Login(ByVal user As String, ByVal pass As String) As String Implements IBasicService.Login
        If user Is Nothing Or pass Is Nothing Then
            Return "No"
        End If
        Dim con = cnc.grpconection
        Dim com = con.CreateCommand()
        com.CommandText = "select * from Emp where UserName = @usr AND password = @pass"
        com.Parameters.AddWithValue("@usr", user)
        com.Parameters.AddWithValue("@pass", pass)
        con.Open()
        Dim reader = com.ExecuteReader()
        Try
            reader.Read()
            If reader.HasRows Then
                Return "Yes"
            End If
            Return "No"
        Finally
            reader.Close()
            com.Dispose()
            con.Close()
        End Try
    End Function

使用界面功能

<OperationContract()>
<WebInvoke(Method:="GET", ResponseFormat:=WebMessageFormat.Xml, BodyStyle:=WebMessageBodyStyle.Bare, UriTemplate:="login?user={user}&pass={pass}")>
Function Login(ByVal user As String, ByVal pass As String) As String
