WCF 和自定義身份驗證(用戶名/密碼)

[英]WCF and custom Authentication (username/password)

我有 Windows Forms 客戶端通過 Internet 連接到 WCF 服務。 WCF 服務托管在 Windows 服務中,該服務在專用 Windows 帳戶下運行。 我想通過檢查用戶名+密碼對來針對數據庫驗證客戶端。

為了避免數百種方法,例如:

public int Add(string User, string Password, int A, int B)

我使用以下指南覆蓋UserNamePasswordValidator class:

我的自定義身份驗證器 class 與示例匹配

class UsernameAuthentication : UserNamePasswordValidator
    {
        public override void Validate(string userName, string password)
        {
            //Will be checked against database
            var ok = (userName == "Ole") && (password == "Pwd");
            if (ok == false)
                throw new AuthenticationException("u/p does not match");
        }
    }

我的服務器配置是:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.7.2" />
    </startup>
  <system.serviceModel>

    <services>
      <service name="TestWCFCustomAuth.CalculatorService" behaviorConfiguration="customCred">
        <endpoint address="CalcSvc"
                  binding="netTcpBinding"
                  bindingConfiguration="secUP"
                  contract="ServiceInterface.ICalculatorService"/>
        <endpoint address="mex" binding="mexHttpBinding" contract="ServiceInterface.ICalculatorService" />
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:81/"/>
            <add baseAddress="net.tcp://localhost:82/"/>
          </baseAddresses>
        </host>
      </service>
    </services>

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

    <behaviors>
      <serviceBehaviors>
        <behavior name="customCred">
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
          <serviceCredentials>
            <!--Service identity + encryption certificate-->
            <serviceCertificate findValue="SHKIService" storeLocation="LocalMachine" storeName="Root" x509FindType="FindBySubjectName"/>
            <userNameAuthentication userNamePasswordValidationMode="Custom"
              customUserNamePasswordValidatorType="TestWCFCustomAuth.UsernameAuthentication, TestWCFCustomAuth" />
          </serviceCredentials>
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
</configuration>

客戶端是自動生成的:

<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.7.2" />
    </startup>
    
    <system.serviceModel>
        <bindings>
            <netTcpBinding>
                <binding name="NetTcpBinding_ICalculatorService">
                    <security mode="Message">
                        <transport sslProtocols="None" />
                        <message clientCredentialType="UserName" />
                    </security>
                </binding>
            </netTcpBinding>
            <wsHttpBinding>
                <binding name="MetadataExchangeHttpBinding_ICalculatorService">

                </binding>

        </bindings>
        <client>
            <endpoint address="net.tcp://localhost:82/CalcSvc" binding="netTcpBinding"
                bindingConfiguration="NetTcpBinding_ICalculatorService" contract="ServiceReference1.ICalculatorService"
                name="NetTcpBinding_ICalculatorService">
                <identity>
                    <certificate encodedValue="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" />

我做了一個自簽名證書,並把它導入到根目錄,所以證書配置也OK。

測試客戶端代碼是:

var client = new CalculatorServiceClient("NetTcpBinding_ICalculatorService");
client.ClientCredentials.UserName.UserName = "Ole";
client.ClientCredentials.UserName.Password = "Pwd";
var res = client.Add(1, 2);
Console.WriteLine("Result: {0}", res);

盡管我的代碼與指南幾乎相同,但出現錯誤:

System.ServiceModel.Security.SecurityNegotiationException: 'The caller was not authenticated by the service.'
Inner Exception:
FaultException: The request for security token could not be satisfied because authentication failed.

我搜索了幾天的答案並嘗試了許多其他配置。 我最好的猜測是幕后發生了其他類型的身份驗證? 如果是這樣 - 我該如何禁用它?

官方文檔中有完整的demo,使用用戶名密碼驗證,也有證書驗證。 您只需要按照教程中的步驟操作即可成功運行。 你可以參考參考

我缺少的步驟如下:

  1. 為 Windows 服務帳戶授予對證書私鑰的“讀取”權限, 如此處所述

要向帳戶授予對私鑰的權限,可以使用 mmc 的證書管理單元。 可以啟動mms.exe,在“文件”菜單中選擇“添加/刪除管理單元”,選擇“證書”管理單元,然后選擇本地計算機的“計算機帳戶”。 然后應該 select 個人存儲的 SSL 證書,然后使用上下文菜單“管理私鑰...”。

  1. 運行客戶端應用程序的計算機需要在CurrentUser\Trusted People存儲中擁有證書(即使客戶端和服務器在同一台計算機上運行)。 因此,我使用上一步中的 mmc 工具將沒有私鑰的證書導出到文件中,然后將該文件中的證書導入CurrentUser\Trusted People存儲。 我想我必須將此文件包含在我客戶的安裝 package 中。

  2. 這一次我使用makecert.exe工具創建證書,如 @Theobald Du 提供的 msdn 參考中所建議的命令是:

    makecert.exe -sr LocalMachine -ss MY -a sha1 -n CN=<I used server's IP address> -sky exchange -pe

PS 另外我在那台機器上缺少 makecert.exe,所以我從microsoft下載了 Microsoft SDK
