WCF成員資格提供程序引發錯誤：內容類型'application / json; charset = utf-8'不是預期的類型'application / soap + xml; 字符集= UTF-8'

Question

我有一些ASP.NET網站，我正在嘗試將WCF服務設置為成員資格提供程序。 我希望WCF服務處理所有成員資格/角色詳細信息。 登錄/注銷一個將自動登錄/注銷另一個，因此他們都將使用此服務，我想將代碼全部保留在一個位置，而不是每個站點單獨保存。 該服務仍使用標准的Sql Membership提供程序。

嘗試致電時，標題出現錯誤

Membership.ValidateUser(username, password);

從網站。 是否可以在服務或客戶端上指定內容類型？

服務器app.config：

<connectionStrings>
  <clear/>
  <add name="LocalSqlServer" connectionString="SQL_Db_With_Membership_info" providerName="System.Data.SqlClient"/>
</connectionStrings>

  <membership defaultProvider="SqlMembershipProvider">
    <providers>
      <clear/>
      <add name="SqlMembershipProvider"
         type="System.Web.Security.SqlMembershipProvider"
         connectionStringName="LocalSqlServer" />
    </providers>
  </membership>
</system.web>

<system.serviceModel>
  <services>
    <service behaviorConfiguration="AspNetMembership"
        name="Login.LoginService">
      <endpoint address="" binding="wsHttpBinding" 
              bindingConfiguration="LoginBinding"
              name="LoginEndpoint"
              contract="Login.ILoginService">

服務器合同：

[ServiceContract]
public interface ILoginService
{
    [OperationContract]
    bool ValidateUser(string username, string password);
}

public class LoginService : ILoginService
{
    public bool ValidateUser(string username, string password)
    {
        return Membership.ValidateUser(username, password);
    }
}

然后在客戶端的web.config中：

<system.web>
  <membership defaultProvider="ClientAuthenticationMembershipProvider">
    <providers>
      <clear/>
      <add name="ClientAuthenticationMembershipProvider" type="System.Web.ClientServices.Providers.ClientFormsAuthenticationMembershipProvider, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" serviceUri="http://localhost:8733/Design_Time_Addresses/Membership/MembershipService/" />
    </providers>
  </membership>
</system.web>

<system.serviceModel>
  <bindings>
    <wsHttpBinding>
      <binding name="LoginEndpoint" />
    </wsHttpBinding>
  </bindings>
  <client>
    <endpoint address="http://localhost:8733/Design_Time_Addresses/Membership/MembershipService/" binding="wsHttpBinding" bindingConfiguration="LoginEndpoint" contract="LoginService.ILoginService" name="LoginEndpoint" >
    </endpoint>
  </client>
</system.serviceModel>

我想做的是，在后面的登錄頁面代碼中，調用Membership.ValidateUser來登錄用戶，如下所示：

protected void L1_Authenticate(object sender, AuthenticateEventArgs e)
{
    // THIS IS WHERE THE ERROR HAPPENS
    Membership.ValidateUser(L1.UserName, L1.Password);
}

我可以強制服務器接受Json還是強制客戶端發送XML？

嘗試在[OperationContract]屬性之后添加[WebInvoke ]屬性

像這樣的東西

[WebInvoke(Method = "GET",
           RequestFormat = WebMessageFormat.Json,
           ResponseFormat = WebMessageFormat.Json]
