使用 Spring-WS 客户端动态设置自定义 HTTP 标头

Question

使用 Spring-WS 时如何在客户端动态设置自定义 HTTP 标头（不是 SOAP 标头）？

Answer 1

public class AddHttpHeaderInterceptor implements ClientInterceptor {

public boolean handleFault(MessageContext messageContext)
        throws WebServiceClientException {
    return true;
}

public boolean handleRequest(MessageContext messageContext)
        throws WebServiceClientException {
     TransportContext context = TransportContextHolder.getTransportContext();
     HttpComponentsConnection connection =(HttpComponentsConnection) context.getConnection();
     connection.addRequestHeader("name", "suman");

    return true;
}

public boolean handleResponse(MessageContext messageContext)
        throws WebServiceClientException {
    return true;
}

}

配置：

    <bean id="webServiceTemplate" class="org.springframework.ws.client.core.WebServiceTemplate">
    ...
    <property name="interceptors">
        <list>
            <bean class="com.blah.AddHttpHeaderInterceptor" />
        </list>
    </property>
</bean>

Answer 2

ClientInterceptor 非常适合静态标头值。但是当每个请求都应该应用不同的值时，就不可能使用它。在那种情况下WebServiceMessageCallback 很有帮助：

final String dynamicParameter = //...

webServiceOperations.marshalSendAndReceive(request, 
    new WebServiceMessageCallback() {
        void doWithMessage(WebServiceMessage message) {
            TransportContext context = TransportContextHolder.getTransportContext();
            CommonsHttpConnection connection = (CommonsHttpConnection) context.getConnection();
            PostMethod postMethod = connection.getPostMethod();
            postMethod.addRequestHeader( "fsreqid", dynamicParameter );
        }
}

Answer 3

以下片段已使用 Spring 4.0 进行了测试。它将WebServiceMessageCallback 附加到org.springframework.ws.client.core.WebServiceTemplate

final String DYNAMICVALUE = "myDynamo";

WebServiceMessageCallback wsCallback = new WebServiceMessageCallback() {           
       public void doWithMessage(WebServiceMessage message) {
            try {
                        SoapMessage soapMessage = (SoapMessage)message;
                        SoapHeader header = soapMessage.getSoapHeader();
                        header.addAttribute(new QName("myHeaderElement"), DYNAMICVALUE);                        
            } catch (Exception e) {
                        e.printStackTrace();
            }
       }
};

JAXBElement<MyWsResponse> response = (JAXBElement<MyWsResponse>)
        wsTemplate.marshalSendAndReceive(MyWsOP, wsCallback);

Spring 的 webServiceTemplate.marshalSendAndReceive(request) 方法内部使用 HttpComponentsMessageSender 通过网络发送 SOAP 消息，这进一步使用 WebServiceConnection 与服务器建立 http 连接。您所要做的就是编写自己的自定义 HttpComponentsMessageSender 并在 postMethod 中设置 cookie。

客户发件人代码：

    package com.swap.ws.sender;

import java.io.IOException;
import java.net.URI;

import javax.annotation.Resource;

import org.apache.http.client.methods.HttpPost;
import org.apache.log4j.Logger;
import org.springframework.stereotype.Service;
import org.springframework.ws.transport.WebServiceConnect ion;
import org.springframework.ws.transport.http.HttpComponen tsConnection;

/**
* 
* @author swapnil Z
*/
@Service("urlMessageSender")
public class CustomHttpComponentsMessageSender extends
org.springframework.ws.transport.http.HttpComponen tsMessageSender {
private static Logger _logger = Logger.getLogger("");


@Override
public WebServiceConnection createConnection(URI uri) throws IOException {
String cookie = null;
HttpComponentsConnection conn = (HttpComponentsConnection) super
.createConnection(uri);
HttpPost postMethod = conn.getHttpPost();
cookie = "<Your Custom Cookie>";

postMethod.addHeader("Cookie", cookie);

return conn;
}
}

弹簧配置：

<bean id="messageFactory" class="org.springframework.ws.soap.saaj.SaajSoapMe ssageFactory" />

<bean id="marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshalle r">
<property name="contextPath" value="com.swap.provision" />
</bean>

<bean id="webServiceTemplate" class="org.springframework.ws.client.core.WebServi ceTemplate">
<constructor-arg ref="messageFactory" />
<property name="marshaller" ref="marshaller"></property>
<property name="unmarshaller" ref="marshaller"></property>
<property name="messageSender" ref="urlMessageSender"/>
<property name="defaultUri" value=<Server URL> />
</bean>

在此之后，我只需获取 bean webServiceTemplate 并调用 marshalSendAndReceive 方法。因此，在进行 HTTP 调用之前，每个请求都会设置其自定义 cookie。

当使用spring integration 3和spring integration-ws时，可以使用以下代码来处理请求：

public boolean handleRequest(MessageContext messageContext)
        throws WebServiceClientException {
    TransportContext context = TransportContextHolder.getTransportContext();
    HttpUrlConnection connection = (HttpUrlConnection) context
    .getConnection();
    connection.getConnection().addRequestProperty("HEADERNAME",
    "HEADERVALUE");

    return true;
}

拦截器可以通过以下方式连接到出站网关：

<ws:outbound-gateway ...            
        interceptor="addPasswordHeaderInterceptor" >
</ws:outbound-gateway>

<bean id="addPasswordHeaderInterceptor class="com.yourfirm.YourHttpInterceptor" />

Answer 6

其实它是@Tomasz的答案的更新版本，但是提供了新的Spring-WS API、Java 8快捷方式，并且关心用单独的方法创建WebServiceMessageCallback实例。

我相信它更明显和自给自足。

final class Service extends WebServiceGatewaySupport {

    /**
     * @param URL       the URI to send the message to
     * @param payload   the object to marshal into the request message payload
     * @param headers   HTTP headers to add to the request
     */
    public Object performRequestWithHeaders(String URL, Object payload, Map<String, String> headers) {
        return getWebServiceTemplate()
                .marshalSendAndReceive(URL, payload, getRequestCallback(headers));
    }

    /**
     * Returns a {@code WebServiceMessageCallback} instance with custom HTTP headers.
     */
    private WebServiceMessageCallback getRequestCallback(Map<String, String> headers) {
        return message -> {
            TransportContext context = TransportContextHolder.getTransportContext();
            HttpUrlConnection connection = (HttpUrlConnection)context.getConnection();
            addHeadersToConnection(connection, headers);
        };
    }

    /**
     * Adds all headers from the {@code headers} to the {@code connection}.
     */
    private void addHeadersToConnection(HttpUrlConnection connection, Map<String, String> headers){
        headers.forEach((name, value) -> {
            try {
                connection.addRequestHeader(name, value);
            } catch (IOException e) {
                e.printStackTrace(); // or whatever you want
            }
        });
    }

}

Answer 7

使用 java 1.8 的示例方法：如何添加 HTTP 标头：

public void executeObjectWebservice(String id) {
        ExecuteObject request = new ExecuteObject();
        getWebServiceTemplate().marshalSendAndReceive("http://url/webservice-test/uc4ws",
                new ObjectFactory().createExecuteObject(request), new WebServiceMessageCallback() {
                    public void doWithMessage(WebServiceMessage message) throws IOException {
                        TransportContext context = TransportContextHolder.getTransportContext();
                        HttpUrlConnection connection = (HttpUrlConnection) context.getConnection();
                        connection.addRequestHeader("ID", id);
                    }
                });    
        }

解释： 使用 getWebServiceTemplate().marshalSendAndReceive，例如此处所述：https://spring.io/guides/gs/consuming-web-service/

第一个参数是URI，第二个参数是请求发送的对象。作为第三个参数，您可以添加为函数

new WebServiceMessageCallback()

覆盖public void doWithMessage 的位置。此方法在发送请求之前被调用。您可以在其中访问消息并通过

添加请求标头

TransportContext context = TransportContextHolder.getTransportContext();
HttpUrlConnection connection = (HttpUrlConnection) context.getConnection();
connection.addRequestHeader("ID", id);
