spring-oauth2 登录成功处理程序

有没有办法使用 spring-oauth2 添加登录成功处理程序？

我尝试使用基本身份验证过滤器，但它仅过滤客户端凭据而不是用户凭据。

或者我是否需要创建自定义用户身份验证管理器？

TIA

该解决方案适用于密码流，也适用于我不确定的其他解决方案。 您可以在 oauth-server 配置中的 http 标记中的“before=BASIC_AUTH_FILTER”位置添加自定义过滤器， 您可以通过解析“oauth/token”的响应来实现，因此创建 ByteArrayResponseWrapper 来获取响应， 在这里，我使用“org.apache.commons commons-io”中的 TeeOutputStream 类，

private class ByteArrayResponseWrapper extends HttpServletResponseWrapper {

    public ByteArrayResponseWrapper(ServletResponse response) {
        super((HttpServletResponse) response);
    }

    private ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();

    @Override
    public ServletOutputStream getOutputStream() throws IOException {
        return new DelegatingServletOutputStream(new TeeOutputStream(
                super.getOutputStream(), byteArrayOutputStream));
    }

    public byte[] getByteArray() {
        return this.byteArrayOutputStream.toByteArray();
    }
}

我创建了令牌提取器来分离提取 access_token 的代码

public class OAuth2AccessTokenExtractor implements
    OAuth2AccessTokenExtractor {

private ObjectMapper mapper = new ObjectMapper();

public String getAccessTokenValue(byte[] response) {
    try {
        return mapper.readValue(response, OAuth2AccessToken.class)
                .getValue();
    } catch (JsonParseException e) {
        e.printStackTrace();
    } catch (JsonMappingException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    return null;
 }

}

创建过滤器后覆盖 doFilter 像这样

private DefaultTokenServices tokenServices;

private OAuth2AccessTokenExtractor tokenExtractor;

@Override
public void doFilter(ServletRequest request, ServletResponse response,
        FilterChain chain) throws IOException, ServletException {

    // create wrapper to read response body
    ByteArrayResponseWrapper responseWraper = new ByteArrayResponseWrapper(
            response);

    // led them go
    chain.doFilter(request, responseWraper);

    // get ClientAuthentication
    Authentication clientAuthentication = SecurityContextHolder
            .getContext().getAuthentication();

    // is authenticated or not to proceed
    if (clientAuthentication != null
            && clientAuthentication.isAuthenticated()) {

        // callBack client authenticated successfully
        onSuccessfulClientAuthentication(request, response,
                clientAuthentication);

        // check response status is success of failure
        if (responseWraper.getStatus() == 200) {

            // extract accessToken from response
            String token = tokenExtractor
                    .getAccessTokenValue(responseWraper.getByteArray());

            if (token != null && !token.isEmpty()) {

                // load authentication from token
                OAuth2Authentication oAuth2Authentication = this.tokenServices
                        .loadAuthentication(token);
                OAuth2AccessToken actualAccessToken = this.tokenServices
                        .getAccessToken(oAuth2Authentication);

                // callBack user authenticated successfully
                onSuccessfulUserAuthentication(request, response,
                        clientAuthentication, oAuth2Authentication,
                        actualAccessToken);
            } else {
                log.error("access token is empty from extractor");
            }
        } else {
            // callBack user authenticated failure
            onFailureUserAuthentication(request, response,
                    clientAuthentication, request.getParameter("username"));
        }
    } else {
        // callBack client authenticated failure
        onFailClientAuthentication(request, response,
                request.getParameter(OAuth2Utils.CLIENT_ID));
    }
}

protected void onSuccessfulClientAuthentication(ServletRequest request,
        ServletResponse response, Authentication authentication) {
}

protected void onFailClientAuthentication(ServletRequest request,
        ServletResponse response, String clientId) {
}

protected void onSuccessfulUserAuthentication(ServletRequest request,
        ServletResponse response, Authentication clientAuthentication,
        OAuth2Authentication userOAuth2Authentication,
        OAuth2AccessToken token) {
}

protected void onFailureUserAuthentication(ServletRequest request,
        ServletResponse response, Authentication clientAuthentication,
        String username) {
}

在创建过滤器实例时注入 tokenServices。 现在 onSuccessfulClientAuthentication、onFailClientAuthentication、onSuccessfulUserAuthentication 和 onFailureUserAuthentication 将根据您的身份验证被调用

Edited:

当您有默认令牌响应并且仅使用 ServletResponseWrapper 并提取时，上面的代码片段工作正常。 但它仍然看起来很脆弱，所以你可以通过以下方式了解用户身份验证是否成功org.springframework.security.oauth2.provider.token.TokenEnhancer class
