web-services - 如何在 Liferay WebService 中获取 HttpServletRequest

Question

嗨，我有一个从 Liferay 的 buildServices 生成的 webService.. 该方法如下所示

 public User getUserTest(long userId) {

    User u = null;
    try {
        Token token = OAuthFactoryUtil.createToken("sasa", "sdad");
    } catch (OAuthException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }

    try {
        u = UserLocalServiceUtil.getUser(userId);
        System.out.println("xx user " + u.getScreenName());
    } catch (Exception e) {
        System.out.println(" Exception ************* " + e.toString());
    }

    return u;
} 

此 ws 中的参数如下:

http://localhost:8080/demo-portlet/api/json?serviceClassName=com.sample.portlet.library.service.BookServiceUtil&serviceMethodName=getUserTest&userId=10195&serviceParameters=[userId]

将userId作为参数..

如果您需要HttpServletRequest，您将如何传递参数..我的方法如下所示

public User getUserTest(HttpServletRequest httpRequest) {

    User u = null;

    try {

        String version = httpRequest.getHeader("X-PHM-APP-VERSION");
        Token token = OAuthFactoryUtil.createToken("sasa", "sdad");
    } catch (OAuthException e1) {
        e1.printStackTrace();
    }

    try {
        String authorization = httpRequest.getHeader("Authorization");
        u = UserLocalServiceUtil.getUser(Long.valueOf(authorization));
        System.out.println("authorization --> " + authorization);
        System.out.println("xx user " + u.getScreenName());
    } catch (Exception e) {
        System.out.println(" Exception ************* " + e.toString());
    }

    return u;
}

我需要HttpServletRequest从 header 获取参数，而不是通过url传递。有没有更好的方法从 header 获取参数？感谢您的帮助

我认为 Web 服务层通常处于后期阶段，您永远不会传递请求。理想情况下，您要做的是将 header 参数传递给网络服务而不是请求
