WSO2 ESB使用多个cookie从传输标题获取cookie

Question

我使用凭据调用认证服务，并使用认证信息响应返回的cookie。我需要这些信息来访问Web服务。

问题是，身份验证服务返回多个cookie的响应，但我只能访问第一个cookie响应它是我需要访问Web服务的第二个cookie（WSL-external = VhTee1 ...） 。

我从认证服务器得到响应：

HTTP/1.1 200 OK

Set-Cookie: JSESSIONID=000036_xxxxxxx_xxxxxx_xxxxxx:xxxxxxxxx; Path=/

的ESB序列：

<?xml version="1.0" encoding="UTF-8"?> 
<proxy xmlns="http://ws.apache.org/ns/synapse" 
     name="TestLogProxy" 
     transports="https,http"

     trace="disable" 
     startOnLoad="true"> 
    <target> 
     <inSequence> 
     <property name="uri.var.userid" value="userid"/> 
     <property name="uri.var.password" value="password"/> 
     <send> 
      <endpoint> 
       <http method="GET" 
        uri-template="https://www.company.biz/auth.cgi?userid={uri.var.userid}&amp;password={uri.var.password}"/> 
      </endpoint> 
     </send> 
     </inSequence> 
     <outSequence> 
     <property name="setCookieHeader" 
        expression="$trp:Set-Cookie" 
        scope="default" 
        type="STRING"/> 
     <log level="custom"> 
      <property name="setCookieHeader value" expression="$ctx:setCookieHeader"/> 
     </log> 
     <send/> 
     </outSequence> 
    </target> 
    <description/> 
</proxy> 

我得到的日志消息：

setCookieHeader value = JSESSIONID=000036_xxxxxxx_xxxxxx_xxxxxx:xxxxxxxxx; Path=/ 

我有也试图让我自己的班调解员：

package org.wso2.mediator; 

import java.util.Map; 

import org.apache.synapse.MessageContext; 
import org.apache.synapse.core.axis2.Axis2MessageContext; 
import org.apache.synapse.mediators.AbstractMediator; 

public class CookieMediator extends AbstractMediator { 

    public boolean mediate(MessageContext synCtx) { 
     try { 
      System.out.println("CookieMediator doing stuff..."); 

      // Extracting transport headers 
      org.apache.axis2.context.MessageContext msgContext = ((Axis2MessageContext) synCtx).getAxis2MessageContext(); 

      Map headersMap = (Map) msgContext.getProperty(org.apache.axis2.context.MessageContext.TRANSPORT_HEADERS); 

      // Printing the cookie 
      System.out.println("Cookie: " + headersMap.get("Set-Cookie")); 

      } catch (Exception e) { 
      System.out.println("Exception: " + e); 
      handleException("Exception", e, synCtx); 
      } 

     return true; 
    } 
} 

而且从序列像这样调用它：

<class name="org.wso2.mediator.CookieMediator"/> 

但它也只返回第一个Cookie：

Cookie: JSESSIONID=000036_xxxxxxx_xxxxxx_xxxxxx:xxxxxxxxx; Path=/ 

我已经看过这些帖子，但它不会与帮助我有第二个饼干问题：

In WSO2 ESB, how to store cookies and use them later for authentication?

WSO2 ESB - How to get and set cookies in WSDL calls in

谢谢。

UPDATE：

我下面的解决方案：

package org.wso2.mediator; 

import java.util.Map; 
import org.apache.synapse.MessageContext; 
import org.apache.synapse.core.axis2.Axis2MessageContext; 
import org.apache.synapse.mediators.AbstractMediator; 

public class CookieMediator extends AbstractMediator { 

    public boolean mediate(MessageContext synCtx) { 
     try { 
      System.out.println("CookieMediator extracting cookie..."); 

      // Extracting cookie from excess headers 
      org.apache.axis2.context.MessageContext msgContext = ((Axis2MessageContext) synCtx).getAxis2MessageContext(); 
      Map excessHeaders = (Map) msgContext.getProperty("EXCESS_TRANSPORT_HEADERS"); 

      if (excessHeaders != null) { 
       String cookie = excessHeaders.get("Set-Cookie").toString().split(";")[0]; 

       if (cookie.startsWith("[WSL-external")) { 
        System.out.println("Cookie: " + cookie.substring(1)); 
       } 
      } 
      } catch (Exception e) { 
      System.out.println("Exception: " + e); 
      handleException("Exception", e, synCtx); 
      } 

     return true; 
    } 
} 

Answer 1

您可能需要从EXCESS_TRANSPORT_HEADERS地图得到这个。

Map excessHeaders = (Map) synCtx.getProperty(NhttpConstants.EXCESS_TRANSPORT_HEADERS); 

更具体地说，这是一个包含多值标头的MultiValueMap。
