OAuth2.0授权码/oauth/authorize接口调用unauthorized异常

调用/oauth/authorize接口时,代码首先进入org.springframework.web.method.support.InvocableHandlerMethod类的invokeForRequest方法;代码如下:

@Nullable
	public Object invokeForRequest(NativeWebRequest request, @Nullable ModelAndViewContainer mavContainer,
			Object... providedArgs) throws Exception {

		Object[] args = getMethodArgumentValues(request, mavContainer, providedArgs);
		if (logger.isTraceEnabled()) {
			logger.trace("Invoking '" + ClassUtils.getQualifiedMethodName(getMethod(), getBeanType()) +
					"' with arguments " + Arrays.toString(args));
		}
		Object returnValue = doInvoke(args);
		if (logger.isTraceEnabled()) {
			logger.trace("Method [" + ClassUtils.getQualifiedMethodName(getMethod(), getBeanType()) +
					"] returned [" + returnValue + "]");
		}
		return returnValue;
	}

通过Object returnValue = doInvoke(args);方法调用org.springframework.security.oauth2.provider.endpoint.AuthorizationEndpoint类的authorize方法;

	@RequestMapping(value = "/oauth/authorize")
	public ModelAndView authorize(Map model, @RequestParam Map parameters,
			SessionStatus sessionStatus, Principal principal) {

		// Pull out the authorization request first, using the OAuth2RequestFactory. All further logic should
		// query off of the authorization request instead of referring back to the parameters map. The contents of the
		// parameters map will be stored without change in the AuthorizationRequest object once it is created.
		AuthorizationRequest authorizationRequest = getOAuth2RequestFactory().createAuthorizationRequest(parameters);

		Set responseTypes = authorizationRequest.getResponseTypes();

		if (!responseTypes.contains("token") && !responseTypes.contains("code")) {
			throw new UnsupportedResponseTypeException("Unsupported response types: " + responseTypes);
		}

		if (authorizationRequest.getClientId() == null) {
			throw new InvalidClientException("A client id must be provided");
		}

		try {

			if (!(principal instanceof Authentication) || !((Authentication) principal).isAuthenticated()) {
				throw new InsufficientAuthenticationException(
						"User must be authenticated with Spring Security before authorization can be completed.");
			}

			ClientDetails client = getClientDetailsService().loadClientByClientId(authorizationRequest.getClientId());

			// The resolved redirect URI is either the redirect_uri from the parameters or the one from
			// clientDetails. Either way we need to store it on the AuthorizationRequest.
			String redirectUriParameter = authorizationRequest.getRequestParameters().get(OAuth2Utils.REDIRECT_URI);
			String resolvedRedirect = redirectResolver.resolveRedirect(redirectUriParameter, client);
			if (!StringUtils.hasText(resolvedRedirect)) {
				throw new RedirectMismatchException(
						"A redirectUri must be either supplied or preconfigured in the ClientDetails");
			}
			authorizationRequest.setRedirectUri(resolvedRedirect);

			// We intentionally only validate the parameters requested by the client (ignoring any data that may have
			// been added to the request by the manager).
			oauth2RequestValidator.validateScope(authorizationRequest, client);

			// Some systems may allow for approval decisions to be remembered or approved by default. Check for
			// such logic here, and set the approved flag on the authorization request accordingly.
			authorizationRequest = userApprovalHandler.checkForPreApproval(authorizationRequest,
					(Authentication) principal);
			// TODO: is this call necessary?
			boolean approved = userApprovalHandler.isApproved(authorizationRequest, (Authentication) principal);
			authorizationRequest.setApproved(approved);

			// Validation is all done, so we can check for auto approval...
			if (authorizationRequest.isApproved()) {
				if (responseTypes.contains("token")) {
					return getImplicitGrantResponse(authorizationRequest);
				}
				if (responseTypes.contains("code")) {
					return new ModelAndView(getAuthorizationCodeResponse(authorizationRequest,
							(Authentication) principal));
				}
			}

			// Place auth request into the model so that it is stored in the session
			// for approveOrDeny to use. That way we make sure that auth request comes from the session,
			// so any auth request parameters passed to approveOrDeny will be ignored and retrieved from the session.
			model.put("authorizationRequest", authorizationRequest);

			return getUserApprovalPageResponse(model, authorizationRequest, (Authentication) principal);

		}
		catch (RuntimeException e) {
			sessionStatus.setComplete();
			throw e;
		}

	}

在这个方法中,如果principal为null时即生成User must be authenticated with Spring Security before authorization can be completed.异常。

			if (!(principal instanceof Authentication) || !((Authentication) principal).isAuthenticated()) {
				throw new InsufficientAuthenticationException(
						"User must be authenticated with Spring Security before authorization can be completed.");
			}

 

principal在org.springframework.web.servlet.mvc.method.annotation.ServletRequestMethodArgumentResolver类的resolveArgument方法中生成的。在resolveArgument方法中第162行中 Principal userPrincipal = request.getUserPrincipal();如果request中不存在用户信息,则Principal 无法取得,造成参数为Null情况。

	@Nullable
	private Object resolveArgument(Class paramType, HttpServletRequest request) throws IOException {
		if (HttpSession.class.isAssignableFrom(paramType)) {
			HttpSession session = request.getSession();
			if (session != null && !paramType.isInstance(session)) {
				throw new IllegalStateException(
						"Current session is not of type [" + paramType.getName() + "]: " + session);
			}
			return session;
		}
		else if (pushBuilder != null && pushBuilder.isAssignableFrom(paramType)) {
			return PushBuilderDelegate.resolvePushBuilder(request, paramType);
		}
		else if (InputStream.class.isAssignableFrom(paramType)) {
			InputStream inputStream = request.getInputStream();
			if (inputStream != null && !paramType.isInstance(inputStream)) {
				throw new IllegalStateException(
						"Request input stream is not of type [" + paramType.getName() + "]: " + inputStream);
			}
			return inputStream;
		}
		else if (Reader.class.isAssignableFrom(paramType)) {
			Reader reader = request.getReader();
			if (reader != null && !paramType.isInstance(reader)) {
				throw new IllegalStateException(
						"Request body reader is not of type [" + paramType.getName() + "]: " + reader);
			}
			return reader;
		}
		else if (Principal.class.isAssignableFrom(paramType)) {
			Principal userPrincipal = request.getUserPrincipal();
			if (userPrincipal != null && !paramType.isInstance(userPrincipal)) {
				throw new IllegalStateException(
						"Current user principal is not of type [" + paramType.getName() + "]: " + userPrincipal);
			}
			return userPrincipal;
		}
		else if (HttpMethod.class == paramType) {
			return HttpMethod.resolve(request.getMethod());
		}
		else if (Locale.class == paramType) {
			return RequestContextUtils.getLocale(request);
		}
		else if (TimeZone.class == paramType) {
			TimeZone timeZone = RequestContextUtils.getTimeZone(request);
			return (timeZone != null ? timeZone : TimeZone.getDefault());
		}
		else if (ZoneId.class == paramType) {
			TimeZone timeZone = RequestContextUtils.getTimeZone(request);
			return (timeZone != null ? timeZone.toZoneId() : ZoneId.systemDefault());
		}

		// Should never happen...
		throw new UnsupportedOperationException("Unknown parameter type: " + paramType.getName());
	}
