本文介紹了通過 Javascript 發(fā)送 Authorization Token Bearer的處理方法，對大家解決問題具有一定的參考價值，需要的朋友們下面隨著小編來一起學習吧！

問題描述

我正在嘗試通過 Javascript 將授權令牌承載發(fā)送到 REST 端點，所以我這樣做:

I'm trying to send a Authorization Token Bearer through Javascript to a REST Endpoint, so i doing in this way:

$.ajax( {
    url: 'http://localhost:8080/resourceserver/protected-no-scope',
    type: 'GET',
    beforeSend : function( xhr ) {
        xhr.setRequestHeader( "Authorization", "Bearer " + token );
    },
    success: function( response ) {
        console.log(response);
    }

我的端點在 SpringBoot 容器下運行，所以我正在獲取 HttpServletRequest 并嘗試獲取 AUthorization Header 但始終為空:

My endpoint is running under a SpringBoot container, so i'm getting the HttpServletRequest and trying to get AUthorization Header but is always null:

static Authentication getAuthentication(HttpServletRequest request) {
        String token = request.getHeader(HEADER_STRING);
        //token is always null
...

編輯 1這是客戶端(瀏覽器)中的錯誤

Edit 1 This is the error in Client-Side (Browser

OPTIONS http://localhost:8080/resourceserver/protected-no-scope 403 ()
Failed to load http://localhost:8080/resourceserver/protected-no-scope: Response for preflight has invalid HTTP status code 403.

編輯 2為了在后端啟用 CORS，我在 spring 中使用了以下注釋:

Edit 2 To enable CORS in backend i'm using the following annotation with spring:

@RestController
@CrossOrigin(origins = "*", maxAge = 3600, allowCredentials = "true", allowedHeaders = "Authorization", methods =
        {RequestMethod.GET, RequestMethod.OPTIONS, RequestMethod.POST})
public class MyResource {

編輯 3我嘗試在我的過濾器中添加 CORS，但沒有成功:

Edit 3 I tried added the CORS in my Filter but no success:

public void doFilter(ServletRequest request, ServletResponse response, FilterChain filterChain)
            throws IOException, ServletException {

        HttpServletRequest httpServletRequest = (HttpServletRequest) request;
        HttpServletResponse httpServletResponse = (HttpServletResponse) response;

        httpServletResponse.setHeader("Access-Control-Allow-Origin", httpServletRequest.getHeader("Origin"));
        httpServletResponse.setHeader("Access-Control-Allow-Credentials", "true");
        httpServletResponse.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
        httpServletResponse.setHeader("Access-Control-Max-Age", "3600");
        httpServletResponse.setHeader("Access-Control-Allow-Headers", "Content-Type, Accept, X-Requested-With, remember-me");


        Authentication authentication = TokenAuthenticationService
                .getAuthentication(httpServletRequest);

        SecurityContextHolder.getContext().setAuthentication(authentication);
        filterChain.doFilter(request, response);
    }

推薦答案

您可以使用headers鍵添加標題

$.ajax({
   url: 'http://localhost:8080/resourceserver/protected-no-scope',
   type: 'GET',
   contentType: 'application/json'
   headers: {
      'Authorization': 'Bearer <token>'
   },
   success: function (result) {
       // CallBack(result);
   },
   error: function (error) {

   }
});

您需要在后端啟用 CORS

You need to enable CORS on backend
