更新:使用 Spring 4.1,可以将用户设置为从上面的 #1 握手。根据Spring 文档,您可以创建一个扩展 DefaultHandshakeHandler 的新类并覆盖 determineUser 方法。此外,如果您有令牌,您还可以创建一个设置主体的安全过滤器。我自己实现了第二个,并在下面包含了一些示例代码。
对于#2 和#3,我认为这仍然是不可能的。对于 #4 Spring 故意忽略这些文档 here。
DefaultHandshakeHandler 子类的示例代码:
@Configuration
@EnableWebSocketMessageBroker
public class ApplicationWebSocketConfiguration extends AbstractWebSocketMessageBrokerConfigurer {
public class MyHandshakeHandler extends DefaultHandshakeHandler {
@Override
protected Principal determineUser(ServerHttpRequest request, WebSocketHandler wsHandler,
Map<String, Object> attributes) {
// add your own code to determine the user
return null;
}
}
@Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
registry.addEndpoint("/myEndPoint").setHandshakeHandler(new MyHandshakeHandler());
}
}
安全过滤器的示例代码:
public class ApplicationSecurityTokenFilter extends GenericFilterBean {
private final static String AUTHENTICATION_PARAMETER = "authentication";
@Override
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
if (servletRequest instanceof HttpServletRequest) {
// check to see if already authenticated before trying again
Authentication existingAuth = SecurityContextHolder.getContext().getAuthentication();
if ((existingAuth == null) || !existingAuth.isAuthenticated()) {
HttpServletRequest request = (HttpServletRequest)servletRequest;
UsernamePasswordAuthenticationToken token = extractToken(request);
// dump token into security context (for authentication-provider to pick up)
if (token != null) { // if it exists
SecurityContextHolder.getContext().setAuthentication(token);
}
}
}
filterChain.doFilter(servletRequest,servletResponse);
}
private UsernamePasswordAuthenticationToken extractToken( HttpServletRequest request ) {
UsernamePasswordAuthenticationToken authenticationToken = null;
// do what you need to extract the information for a token
// in this example we assume a query string that has an authenticate
// parameter with a "user:password" string. A new UsernamePasswordAuthenticationToken
// is created and then normal authentication happens using this info.
// This is just a sample and I am sure there are more secure ways to do this.
if (request.getQueryString() != null) {
String[] pairs = request.getQueryString().split("&");
for (String pair : pairs) {
String[] pairTokens = pair.split("=");
if (pairTokens.length == 2) {
if (AUTHENTICATION_PARAMETER.equals(pairTokens[0])) {
String[] tokens = pairTokens[1].split(":");
if (tokens.length == 2) {
log.debug("Using credentials: " + pairTokens[1]);
authenticationToken = new UsernamePasswordAuthenticationToken(tokens[0], tokens[1]);
}
}
}
}
}
return authenticationToken;
}
}
// set up your web security for the area in question
@Configuration
public class SubscriptionWebSecurityConfigurationAdapter extends WebSecurityConfigurerAdapter {
protected void configure(HttpSecurity http) throws Exception {
http
.requestMatchers().antMatchers("/myEndPoint**","/myEndPoint/**").and()
.addFilterBefore(new ApplicationSecurityTokenFilter(), UsernamePasswordAuthenticationFilter.class)
.authorizeRequests()
.anyRequest().authenticated()
.and()
.httpBasic() // leave this if you want non web browser clients to connect and add an auth header
.and()
.csrf().disable();
}
}
**注意: ** 不要将您的过滤器声明为 Bean。如果你这样做了,那么它也会在通用过滤器中被拾取(至少使用 Spring Boot),所以它会在每个请求上触发。
