WCF .net 4.0 HTTP基本身份验证

Question

我现在已经为此吵了几天了.

我只是尝试使用基本HTTP身份验证将用户名/密码传递到我的RESTful服务中.其他一切都很棒!

这是我的web.config看起来像:

<?xml version="1.0"?>
<configuration>

  <system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>

  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true">
      <add name="UrlRoutingModule" type="System.Web.Routing.UrlRoutingModule, System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
    </modules>
  </system.webServer>

  <system.serviceModel>

    <bindings>
      <wsHttpBinding>
        <binding name="">
          <security mode="Message">
            <message clientCredentialType="UserName" />
          </security>
        </binding>
      </wsHttpBinding>
    </bindings>

    <serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>

    <standardEndpoints>
      <webHttpEndpoint>
        <!-- 
            Configure the WCF REST service base address via the global.asax.cs file and the default endpoint 
            via the attributes on the <standardEndpoint> element below
        -->
        <standardEndpoint name="" helpEnabled="true" defaultOutgoingResponseFormat="Json" automaticFormatSelectionEnabled="true"/>
      </webHttpEndpoint>
    </standardEndpoints>

    <behaviors>
      <serviceBehaviors>
        <behavior>
          <serviceCredentials>
            <userNameAuthentication userNamePasswordValidationMode="Custom" customUserNamePasswordValidatorType="ParkingPandaREST.CustomUserNameValidator, ParkingPandaREST" />
          </serviceCredentials>      
        </behavior>
      </serviceBehaviors>
    </behaviors>


  </system.serviceModel>

</configuration>

然后我创建了一个具有以下内容的CustomUserNameValidator类:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace ParkingPandaREST
{
    public class CustomUserNameValidator : System.IdentityModel.Selectors.UserNamePasswordValidator
    {
        // This method validates users. It allows in two users, test1 and test2 
        // with passwords 1tset and 2tset respectively.
        // This code is for illustration purposes only and 
        // must not be used in a production environment because it is not secure.    
        public override void Validate(string userName, string password)
        {
            if (null == userName || null == password)
            {
                throw new ArgumentNullException();
            }

            if (!(userName == "test1" && password == "1tset") && !(userName == "test2" && password == "2tset"))
            {
                // This throws an informative fault to the client.
                throw new System.ServiceModel.FaultException("Unknown Username or Incorrect Password");
                // When you do not want to throw an infomative fault to the client,
                // throw the following exception.
                // throw new SecurityTokenException("Unknown Username or Incorrect Password");
            }
        }
    }
}

我只是在我的本地机器上运行该服务并试图在CustomUserNameValidator类中找到一个断点,但它永远不会到达那里.所以我现在不使用SSL,只是试图获取用户名/密码.

这是我想出的答案。它可能需要进行一些调整，但它是您完成工作所需的核心。

注意：关闭 IIS 中的基本身份验证

           // Get the Header Authorization Value
            string headerValue = operationContext.IncomingRequest.Headers[HttpRequestHeader.Authorization];
            headerValue = headerValue.Replace("Basic ", "");
            headerValue = DecodeBase64String(headerValue);

            // Get Username and Password
            string userName = headerValue.Substring(0, headerValue.IndexOf(":"));
            string password = headerValue.Substring(headerValue.IndexOf(":") + 1, headerValue.Length - userName.Length - 1);

            // Do Custom Authorization here with the userName and password

…………

这里还有 DecodeBase64String 函数

    public static string DecodeBase64String(string encodedData)
    {
        byte[] encodedDataAsBytes = System.Convert.FromBase64String(encodedData);
        string returnValue = System.Text.ASCIIEncoding.ASCII.GetString(encodedDataAsBytes);
        return returnValue;
    }
