登录成功后重定向到原始页面返回原始数据而不是URL名称

Question

我正在使用Spring Security和前端reactJS的Spring Boot构建一个应用程序。我的代码可以很好地进行身份验证。但现在我计划将用户重定向到他以前请求的页面，以防他再次登录。

我可以从成功处理程序中提取 targetUrl，即上一页，但是当我在 UI 上执行控制台.log（数据）时。我得到的是原始的html数据而不是URL名称。我不知道为什么以及如何打开这样的原始 html 代码，或者我可以只从成功处理程序发送 html URL 名称，而不是发送完整的原始 html 代码？任何意见都受到高度赞赏。

预期console.log（数据）-https://localhost:8080/addpage.html

实际控制台. log(数据)-addpage.html的原始html数据

    auth.userDetailsService(userDetailsService).passwordEncoder(bCryptPasswordEncoder());

RESTAuthenticationSuccessHandler.java

@Component
 public class RESTAuthenticationSuccessHandler extends 
 SavedRequestAwareAuthenticationSuccessHandler   {

  private RequestCache requestCache = new HttpSessionRequestCache();

@Override
public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response,
        Authentication authentication) throws IOException, ServletException {

    SavedRequest savedRequest = requestCache.getRequest(request, response);

    System.out.println(savedRequest);

     if (savedRequest == null) {
         HttpSession session = request.getSession();
         if (session != null) {
             String redirectUrl = (String) session.getAttribute("url_prior_login");
             if (redirectUrl != null) {
                 session.removeAttribute("url_prior_login");
                 getRedirectStrategy().sendRedirect(request, response, redirectUrl);
             } else {
                 super.onAuthenticationSuccess(request, response, authentication);
             }
         } else {
             super.onAuthenticationSuccess(request, response, authentication);
         }

         return;
     }

     String targetUrlParameter = getTargetUrlParameter();
     System.out.println(targetUrlParameter);
     if (isAlwaysUseDefaultTargetUrl()
             || (targetUrlParameter != null && StringUtils.hasText(request.getParameter(targetUrlParameter)))) {
         requestCache.removeRequest(request, response);
         super.onAuthenticationSuccess(request, response, authentication);

         return;
     }

     clearAuthenticationAttributes(request);

     // Use the DefaultSavedRequest URL
     String targetUrl = savedRequest.getRedirectUrl();
     System.out.println(targetUrl);
     logger.debug("Redirecting to DefaultSavedRequest Url: " + targetUrl);
     getRedirectStrategy().sendRedirect(request, response, targetUrl);


     }


 }

UI代码：

 $.ajax({
                type: "POST",
                url: "/login",
                data: data,
                success: function(data){
                    console.log(data);
                }.bind(this),
                error:function(data)
                {
                    alert(data.responseJSON.message);
                }
            });

安慰log（data）-返回targetURL的原始html代码，我无法将其作为html文件打开。我需要successhandler中targetURL返回的html文件名，以便我可以使用window.location。href打开文件

听起来像是MIME类型的问题。使用Chrome检查检查您的Web流量并确保您的标头设置正确：

响应标头：

内容类型：text/html；charset=utf-8

请求标头：

接受：text/html

等。

您可以将重定向 URL 返回到响应。

public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response,
    Authentication authentication) throws IOException, ServletException {
 // ... get target url
 String targetUrl = "";
 try {
            response.setStatus(HttpServletResponse.OK);
            PrintWriter writer = response.getWriter();
            writer.write(targetUrl);
            writer.flush();
            writer.close();
        } catch (IOException e) {
            // ignore
            logger.error(e.getMessage(), e);
        } 

}
