删除默认 api 身份验证处理程序并添加 myCustoms 处理程序时出错，知道吗？

Question

（以前它工作正常，但没有改变） 当我从突触配置中删除默认处理程序并添加我的自定义处理程序时，它会给出此错误

[2022-01-13 10:44:41,924] ERROR - ServerWorker Error processing POST request for : /dev/21.2/ext-rt/publish/TestTenant/SmooksProviderTranslation.csv.

下面是 myCustomHandler.java 类的 authenticate() 方法，它有 AuthenticationContext 对象

    public boolean authenticate(MessageContext synCtx) throws APISecurityException {
    Map headers = getTransportHeaders(synCtx);
    String authHeader = getAuthorizationHeader(headers);
    String postmanToken = getPostmanToken(headers);

    String clientIP = "10.110.67.195";

    org.apache.axis2.context.MessageContext axis2MessageContext = ((Axis2MessageContext) synCtx)
            .getAxis2MessageContext();
    AuthenticationContext authContext = new AuthenticationContext();
    authContext.setAuthenticated(true);

    // Can modify to support scopes based throttle policy selection
    authContext.setTier(APIConstants.UNLIMITED_TIER);
    authContext.setStopOnQuotaReach(true);
    authContext.setApiKey(clientIP);
    authContext.setKeyType(APIConstants.API_KEY_TYPE_PRODUCTION);
    authContext.setUsername((String) axis2MessageContext.getProperty("user"));
    authContext.setCallerToken(null);
    authContext.setApplicationName(null);
    authContext.setApplicationId(clientIP);
    authContext.setConsumerKey(null);
    log.debug("**** applicationID is --- " + authContext.getApplicationId());
    APISecurityUtils.setAuthenticationContext(synCtx, authContext, null);

    System.out.println("**** TE is HERE");
    log.debug("**** TE is HERE2");
    log.debug("**** Header is --- " + headers);
    log.debug("**** AuthHeader is --- " + authHeader);
    log.debug("**** Postman token  is --- " + postmanToken);

    return true;
    /*
     * if (authHeader.startsWith("Bearer ")) { return true; } return false;
     */
}

我认为问题出在 AuthenticationContext 对象上。我们在身份验证处理程序（在每个身份验证器 [1] 中）填充 authContext 对象，并且该对象在节流处理程序 [2] 中使用。当您将身份验证处理程序替换为自定义处理程序时，您可能错过了填充此对象。尝试将此对象填充为 [1]。
