当SockJS发生握手时,我需要发送令牌。我尝试了许多建议的实现,但调用了相同的异常
java.lang.IllegalArgumentException: JWT String argument cannot be null or empty.
在后端WebSocketConfig
@Configuration
@EnableWebSocketMessageBroker
@CrossOrigin
public class WebSocketConfig implements WebSocketMessageBrokerConfigurer {
@Override
public void configureMessageBroker(MessageBrokerRegistry config) {
config.enableSimpleBroker("/socket");
config.setApplicationDestinationPrefixes("/app");
}
@Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
registry.addEndpoint("/websocket").withSockJS();
}
}
尝试与套接字建立连接的函数。纯javascript。
function connect() {
var socket = new SockJS('http://localhost:8889/websocket',
null,
{
transports: ['xhr-streaming'],
headers: {'Authorization': 'Bearer eyJhbGciOiJIUzUxMiJ9...' }
});
stompClient = Stomp.over(socket);
stompClient.connect({},function (frame) {
setConnected(true);
console.log('Connected: ' + frame);
stompClient.subscribe('/socket/event', function (greeting) {
showGreeting(JSON.parse(greeting.body).content);
});
});
}
问题出在握手上,那些标题似乎没有正确传递令牌。我尝试了握手的许多变体,但在我的情况下找不到正确的on。
我从这里得到了实现的想法,在我尝试在握手后使用标头之前,但我发现它立即需要令牌。

编辑:添加WebSecurityConfig
@Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
httpSecurity
.cors()
.configurationSource(request -> new CorsConfiguration().applyPermitDefaultValues())
.and()
.csrf()
.disable()
.exceptionHandling().authenticationEntryPoint(unauthorizedHandler).and()
.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and()
.authorizeRequests()
.antMatchers("/login/**").permitAll()
.antMatchers("/websocket/**").permitAll()
.anyRequest().authenticated();
// Custom JWT based security filter
JwtAuthorizationTokenFilter authenticationTokenFilter = new JwtAuthorizationTokenFilter(userDetailsService(), jwtTokenUtil, tokenHeader);
httpSecurity
.addFilterBefore(authenticationTokenFilter, UsernamePasswordAuthenticationFilter.class);
}//end configure(HttpSecurity)
创建认证令牌
@ApiOperation(value = "Login with the user credentials",
response = JwtAuthenticationResponse.class)
@ApiResponses(value = {
@ApiResponse(code = 401, message = "Unauthorized"),
@ApiResponse(code = 404, message = "Not Found",response = ExceptionResponse.class),
@ApiResponse(code = 400, message = "Bad Request",response = ExceptionResponse.class),
@ApiResponse(code = 200 , message = "OK", response = JwtAuthenticationResponse.class)
})
@RequestMapping(value = "${jwt.route.authentication.path}", method = RequestMethod.POST)
public ResponseEntity<?> createAuthenticationToken(
@ApiParam(value = "User's email and password", required = true)
@RequestBody JwtAuthenticationRequest authenticationRequest)
throws AuthenticationException {
ResponseEntity<?> response;
//authenticate the user
final User user = userService.getByEmail(authenticationRequest.getEmail());
try {
authenticate(user.getUsername(), authenticationRequest.getPassword(),user.getId(),user.getAuthority().getName());
// Reload password post-security so we can generate the token
final UserDetails userDetails = userDetailsService.loadUserByUsername(user.getUsername());
final String token = jwtTokenUtil.generateToken(userDetails);
// Return the token
response = ResponseEntity.ok(new JwtAuthenticationResponse(token,user.getUsername(),user.getFirstName(),user.getLastName(),
user.getEmail(),user.getId(),user.getAuthority().getName(),jwtTokenUtil.getExpirationTime(token)));
}catch(NullPointerException e) {
response = new ResponseEntity<>(new ExceptionResponse(404,"User Not Found","Authentication Failure"),HttpStatus.NOT_FOUND);
}catch(AuthenticationException e) {
response = new ResponseEntity<>(new ExceptionResponse(400,"Invalid E-mail or Password","Authentication Failure"),HttpStatus.BAD_REQUEST);
}//end try
return response;
}//end createAuthenticationToken(JwtAuthenticationRequest)
堆栈跟踪(当握手和连接从后端的websocket发生时,相同的异常已被捕获四次)。我在pastebin上添加了它,因为它会破坏帖子。

用于注册自定义身份验证拦截器的服务器端配置。请注意,拦截器只需在CONNECT Message上进行身份验证并设置用户标头。Spring记录并保存经过身份验证的用户,并将其与同一会话上的后续STOMP消息相关联。以下示例显示了如何注册自定义身份验证拦截器:
@Configuration
@EnableWebSocketMessageBroker
public class MyConfig implements WebSocketMessageBrokerConfigurer {
@Override
public void configureClientInboundChannel(ChannelRegistration registration) {
registration.interceptors(new ChannelInterceptor() {
@Override
public Message<?> preSend(Message<?> message, MessageChannel channel) {
StompHeaderAccessor accessor =
MessageHeaderAccessor.getAccessor(message, StompHeaderAccessor.class);
if (StompCommand.CONNECT.equals(accessor.getCommand())) {
Authentication user = ... ; // access authentication header(s)
accessor.setUser(user);
}
return message;
}
});
}
}
另外,请注意,当您使用Spring Security的消息授权时,目前,您需要确保身份验证ChannelInterceptor配置在Spring Security的之前排序。这最好通过在其自己的WebSocketMessageBrokerConfirer实现中声明自定义拦截器来完成,该实现标有@order(有序。HIGHEST_PRECEDENCE99)。
另一种方式:同样,SockJS JavaScript客户端不提供发送带有SockJS传输请求的HTTP标头的方法。如您所见,sockjs-client问题196。相反,它允许发送可用于发送令牌的查询参数,然后使用Spring设置一些过滤器,该过滤器将使用提供的令牌识别会话。,但这有其自身的缺点(例如,令牌可能无意中与服务器日志中的URL一起记录)。

Websocket的不遵循相同的模式在头与HTTP。这就是为什么,即使你发送令牌在头,它无法找到。我以前有同样的问题,我改变了websocket证券结构。
我的示例代码是这样的:
@Override
public void configureClientInboundChannel(ChannelRegistration registration) {
registration.setInterceptors(new ChannelInterceptorAdapter() {
@Override
public Message<?> preSend(Message<?> message, MessageChannel channel) {
StompHeaderAccessor accessor = StompHeaderAccessor.wrap(message);
MessageHeaders headers = message.getHeaders();
SimpMessageType type = (SimpMessageType) headers.get("simpMessageType");
List<String> tokenList = accessor.getNativeHeader("Authorization");
String token = null;
if(tokenList == null || tokenList.size() < 1) {
return message;
} else {
token = tokenList.get(0);
if(token == null) {
return message;
}
}
// validate and convert to a Principal based on your own requirements e.g.
// authenticationManager.authenticate(JwtAuthentication(token))
try{
JwtAuthenticationToken jwtAuthenticationToken = new JwtAuthenticationToken(new RawAccessJwtToken(tokenExtractor.extract(token)));
Authentication yourAuth = jwtAuthenticationProvider.authenticate(jwtAuthenticationToken);
accessor.setUser(yourAuth);
} catch (Exception e) {
throw new IllegalArgumentException(e.getMessage());
}
// not documented anywhere but necessary otherwise NPE in StompSubProtocolHandler!
accessor.setLeaveMutable(true);
return MessageBuilder.createMessage(message.getPayload(), accessor.getMessageHeaders());
}
});
}
