使用会话ID (cookie) 使服务器上的会话ID失效 不接受会话id无效的用户

这适用于IE/Netscape/Chrome浏览器:

      function ClearAuthentication(LogOffPage) 
  {
     var IsInternetExplorer = false;    

     try
     {
         var agt=navigator.userAgent.toLowerCase();
         if (agt.indexOf("msie") != -1) { IsInternetExplorer = true; }
     }
     catch(e)
     {
         IsInternetExplorer = false;    
     };

     if (IsInternetExplorer) 
     {
        // Logoff Internet Explorer
        document.execCommand("ClearAuthenticationCache");
        window.location = LogOffPage;
     }
     else 
     {
        // Logoff every other browsers
    $.ajax({
         username: 'unknown',
         password: 'WrongPassword',
             url: './cgi-bin/PrimoCgi',
         type: 'GET',
         beforeSend: function(xhr)
                 {
            xhr.setRequestHeader("Authorization", "Basic AAAAAAAAAAAAAAAAAAA=");
         },

                 error: function(err)
                 {
                    window.location = LogOffPage;
             }
    });
     }
  }


  $(document).ready(function () 
  {
      $('#Btn1').click(function () 
      {
         // Call Clear Authentication 
         ClearAuthentication("force_logout.html"); 
      });
  });          

正如其他人所说，我们需要获得相同的URL并发送一个错误(例如401:StatusUnauthorized之类的)，仅此而已。

我使用Get方法让它知道我需要登出，

下面是一个使用golang进行写作的完整示例。

package main

import (
    "crypto/subtle"
    "fmt"
    "log"
    "net/http"
)

func BasicAuth(username, password, realm string, handlerFunc http.HandlerFunc) http.HandlerFunc {

    return func(w http.ResponseWriter, r *http.Request) {
        queryMap := r.URL.Query()
        if _, ok := queryMap["logout"]; ok { // localhost:8080/public/?logout
            w.WriteHeader(http.StatusUnauthorized) // 401
            _, _ = w.Write([]byte("Success logout!\n"))
            return
        }

        user, pass, ok := r.BasicAuth()

        if !ok ||
            subtle.ConstantTimeCompare([]byte(user), []byte(username)) != 1 ||
            subtle.ConstantTimeCompare([]byte(pass), []byte(password)) != 1 {
            // https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/WWW-Authenticate
            w.Header().Set("WWW-Authenticate", `Basic realm="`+realm+`", charset="UTF-8"`)
            w.WriteHeader(http.StatusUnauthorized)
            _, _ = w.Write([]byte("Unauthorised.\n"))
            return
        }

        handlerFunc(w, r)
    }
}

type UserInfo struct {
    name string
    psw  string
}

func main() {

    portNumber := "8080"
    guest := UserInfo{"guest", "123"}

    // localhost:8080/public/  -> ./public/everyone
    publicHandler := http.StripPrefix(
        "/public/", http.FileServer(http.Dir("./public/everyone")),
    )

    publicHandlerFunc := func(w http.ResponseWriter, r *http.Request) {
        switch r.Method {
        case http.MethodGet:
            publicHandler.ServeHTTP(w, r)
        /*
            case http.MethodPost:
            case http.MethodPut:
            case http.MethodDelete:
        */
        default:
            return
        }
    }

    http.HandleFunc("/public/",
        BasicAuth(guest.name, guest.psw, "Please enter your username and password for this site",
            publicHandlerFunc),
    )

    log.Fatal(http.ListenAndServe(fmt.Sprintf(":%s", portNumber), nil))
}

当您已经登出时，您需要刷新(F5)页面。否则，您可能会看到旧内容。

对于使用Windows身份验证(也称为协商、Kerberos或NTLM身份验证)的任何人，我使用ASP。NET Core和Angular。

我找到了一种有效的方式来改变用户!

我修改我的登录方法在javascript方面，就像这样:

protected login(changeUser: boolean = false): Observable<AuthInfo> {
  let params = new HttpParams();
  if(changeUser) {
    let dateNow = this.datePipe.transform(new Date(), 'yyyy-MM-dd HH:mm:ss');
    params = params.set('changeUser', dateNow!);
  }
  const url: string = `${environment.yourAppsApiUrl}/Auth/login`;
  return this.http.get<AuthInfo>(url, { params: params });
}

下面是我在后台的方法:

[Route("api/[controller]")]
[ApiController]
[Produces("application/json")]
[Authorize(AuthenticationSchemes = NegotiateDefaults.AuthenticationScheme)]
public class AuthController : Controller
{
  [HttpGet("login")]
  public async Task<IActionResult> Login(DateTime? changeUser = null)
  {
      if (changeUser > DateTime.Now.AddSeconds(-3))
          return Unauthorized();

      ...
      ... (login process)
      ...

      return Ok(await _authService.GetToken());
    }
}

return Unauthorized()返回401代码，导致浏览器识别弹出窗口出现，以下是过程:

如果我想更改用户，我现在将日期作为参数传输。 如果从那一刻起不超过3秒，我就返回401代码。 我完成了我的凭证，并将具有相同参数的相同请求发送到后端。 由于已经过去了3秒多，我继续登录过程，但这次使用的是新的凭据!

function logout() {
  var userAgent = navigator.userAgent.toLowerCase();

  if (userAgent.indexOf("msie") != -1) {
    document.execCommand("ClearAuthenticationCache", false);
  }

  xhr_objectCarte = null;

  if(window.XMLHttpRequest)
    xhr_object = new XMLHttpRequest();
  else if(window.ActiveXObject)
    xhr_object = new ActiveXObject("Microsoft.XMLHTTP");
  else
    alert ("Your browser doesn't support XMLHTTPREQUEST");

  xhr_object.open ('GET', 'http://yourserver.com/rep/index.php', false, 'username', 'password');
  xhr_object.send ("");
  xhr_object = null;

  document.location = 'http://yourserver.com'; 
  return false;
}

其实很简单。

只需在浏览器中访问以下内容，并使用错误的凭据: http://username:password@yourdomain.com

这应该会“让你退出”。
