如何在Java中的Web服务调用中添加或操作HTTP标头 [英] How to add or manipulate http header in a webservice call in java
问题描述
需要在soap请求中添加新的http标头键值对.像下面这样.
There is a requirement to add a new http header key value pair in a soap request. Something like below.
HTTP/1.1 200 OK
Cache-Control: no-cache
Pragma: no-cache
Content-Type: text/xml; charset=utf-8
New-Key: Some dynamic value
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Body>
在发出肥皂请求时,如何在http标头中添加新的键值对(New-Key:某些动态值)?服务器稍后将从http标头中提取值.作为一项要求,不应在肥皂标头或肥皂主体中添加新字段.
How can I add a new key value pair (New-Key: Some dynamic value) in http header while making a soap request? Value will later get extracted by server from http header. As a requirement new field should neither be added in soap header nor in soap body.
我们正在使用IBM wsdl2java工具,该工具实现了IBM JAX-RPC规范以生成Java客户端并调用SOAP Web服务调用.
We are using IBM wsdl2java tool, which implements the IBM JAX-RPC specification to generate the Java clients and invoke the SOAP web service calls.
推荐答案
public class MyApplicationClass {
// Inject an instance of the service's port-type.
@WebServiceRef(EchoService.class)
private EchoPortType port;
// This method will invoke the web service operation and send and receive transport headers.
public void invokeService() {
// Set up the Map that will contain the request headers.
Map<String, Object>requestHeaders = new HashMap<String, Object>();
requestHeaders.put("Cookie", "ClientAuthenticationToken=FFEEBBCC");
requestHeaders.put("MyHeaderFlag", new Boolean(true));
// Set the Map as a property on the RequestContext.
BindingProvider bp = (BindingProvider) port;
bp.getRequestContext().put(com.ibm.websphere.webservices.Constants.REQUEST_TRANSPORT_PROPERTIES, requestHeaders);
// Set up the Map to retrieve transport headers from the response message.
Map<String, Object>responseHeaders = new HashMap<String, Object>();
responseHeaders.put("Set-Cookie", null);
responseHeaders.put("MyHeaderFlag, null);
// Invoke the web services operation.
String result = port.echoString("Hello, world!");
// Retrieve the headers from the response.
String cookieValue = responseHeaders.get("Set-Cookie");
String headerFlag = responseHeaders.get("MyHeaderFlag");
}
}
