Apache CXF - 设置 HTTP header

Question

我必须在 Apache CXF 客户端中设置一些 http header 字段:

我通过拦截器尝试过:

    public class HttpHeaderInterceptor extends AbstractPhaseInterceptor<Message> {

    private String userId;
    private String xAuthorizeRoles;
    private String host;


    public HttpHeaderInterceptor() {
        super(Phase.POST_PROTOCOL);
    }

    @Override
    public void handleMessage(Message message) throws Fault {
        Map<String, List> headers = (Map<String, List>) message.get(Message.PROTOCOL_HEADERS);
        try {
            System.out.println("HttpHeaderInterceptor Host: " + host + " UserId: " + userId + " X-AUTHORIZE-roles: " + xAuthorizeRoles);
            headers.put("Host", Collections.singletonList(host));
            headers.put("UserId", Collections.singletonList(userId));
            headers.put("X-AUTHORIZE-roles", Collections.singletonList(xAuthorizeRoles));
        } catch (Exception ce) {
            throw new Fault(ce);
        }
    }

    public void setUserId(String userId) {
        this.userId = userId;
    }

    public void setxAuthorizeRoles(String xAuthorizeRoles) {
        this.xAuthorizeRoles = xAuthorizeRoles;
    }

    public void setHost(String host) {
        this.host = host;
    }
}

在我的动态客户端类中，方法:

public void setHttHeaderInterceptor(String userId, String xAuthorizeRoles){
    Client cxfClient = ClientProxy.getClient(this.abgWebServicePort);
    HttpHeaderInterceptor httpHeaderInterceptor = new HttpHeaderInterceptor();
    httpHeaderInterceptor.setHost("example.org");
    httpHeaderInterceptor.setUserId(userId);
    httpHeaderInterceptor.setxAuthorizeRoles(xAuthorizeRoles);
    cxfClient.getOutInterceptors().add(httpHeaderInterceptor);
}

在调用远程服务之前调用:

对于每个调用，userId 和 xAuthorizeRoles 应该有所不同，但当我通过 tcpdump 检查调用时，所有调用在 header 字段中具有相同的值。

有什么想法吗？

我已经解决了我的问题:

通过xml配置添加拦截器:

<jaxws:client id="clientBean" serviceClass="org.example.service.ServicePortType"
              address="example.org/src/service/ServicePort">
    <jaxws:outInterceptors>
        <bean class="org.example.interceptor.HttpHeaderInterceptor"/>
    </jaxws:outInterceptors>
    <jaxws:properties>
        <entry key="mtom-enabled" value="true"/>
    </jaxws:properties>
</jaxws:client>

在客户端类中，我将 setHttpHeaderInterceptor 更改为

public void setHttpHeaderInterceptor(String userId, String xAuthorizeRoles){
    Client cxfClient = ClientProxy.getClient(this.servicePort);
    cxfClient.getRequestContext().put("HTTP_HEADER_HOST", "example.org");
    cxfClient.getRequestContext().put("HTTP_HEADER_USER_ID", userId);
    cxfClient.getRequestContext().put("HTTP_HEADER_X_AUTHORIZE-ROLES", xAuthorizeRoles);
}

拦截器类

@Override
    public void handleMessage(Message message) throws Fault {
        Map<String, List> headers = (Map<String, List>) message.get(Message.PROTOCOL_HEADERS);
        try {
            headers.put("Host", Collections.singletonList(message.get("HTTP_HEADER_HOST")));
            headers.put("KD_NR", Collections.singletonList(message.get("HTTP_HEADER_KD_NR")));
            headers.put("X-AUTHORIZE-roles", Collections.singletonList(message.get("HTTP_HEADER_X_AUTHORIZE-ROLES")));
        } catch (Exception ce) {
            throw new Fault(ce);
        }
    }

现在它可以工作了。

通过这种方法，我可以在运行时设置 HTTP header 字段。
