spring-oauth2登录成功处理程序

Question

有没有一种方法可以添加一个登录成功处理程序使用spall-oaut2？

我尝试使用基本身份验证过滤器，但它只过滤客户端凭据，而不是用户凭据。

还是需要创建自定义用户身份验证管理器？

Answer 1

我们构建了一个定制的身份验证管理器，并将其连接到OAuth2AuthenticationProcessingFilter中以实现这一点。管理器的authenticate方法能够从身份验证主体中解压缩OAuth2Authentication和OAuth2AuthenticationDetails。

<bean id="oAuth2AuthenticationManager" class="org.springframework.security.oauth2.provider.authentication.OAuth2AuthenticationManager">
    <property name="resourceId" value="XXX-api"/>
    <property name="tokenServices" ref="tokenServices"/>
</bean>

<bean id="resourceServerFilter"
      class="org.springframework.security.oauth2.provider.authentication.OAuth2AuthenticationProcessingFilter">
    <property name="authenticationManager" ref="oAuth2AuthenticationManager"/>
    <property name="tokenExtractor">
        <bean class="com.xxx.oauth.BearerTokenExtractor"/>
    </property>
</bean>

这个解决方案将适用于密码流和其他我不确定的问题。您可以在oauth服务器配置中的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来获得响应，这里我使用的是“org.apache.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访问令牌的代码

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，像这样覆盖doFilter

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令牌服务。现在将根据您的身份验证调用onSuccessfulClientAuthentication、onFailClientAuthentication、onSuccessfulUserAuthentication和onFailureUserAuthentication

编辑：

当你有默认的令牌响应时，上面的片段可以正常工作，它只是使用ServletResponse seWrapper和提取。但它仍然看起来很脆弱，所以你可以通过了解用户身份验证成功org.springframework.security.oauth2.provider.token.Token增强器类
