在 WSO2 ESB 4.8.1 中配置代理设置 [英] Configuring PROXY settings in WSO2 ESB 4.8.1
问题描述
我是 wso2 的新手.. 我在使用 wso2esb 代理服务调用外部 SOAP 服务时遇到问题.. 我在公司代理中使用 WSO2 ESB.. 我可以直接使用肥皂客户端..
是否需要在 WSO2 ESB 中设置任何代理配置?
我在使用 wso2proxy 服务连接肥皂服务时遇到以下异常

在/repository/conf/axis2/axis2.xml中，编辑http传输的transportSender配置，指定代理服务器如下:
<parameter name="non-blocking" locked="false">true</parameter><parameter name="http.proxyHost" locked="false">proxyhost.yourdomain</parameter><parameter name="http.proxyPort" locked="false">proxyport</parameter></transportSender> 在向此代理服务器发送消息的代理服务的 Synapse 配置中，在发送中介之前设置以下两个属性:

Is there any proxy configuration that I need to set in WSO2 ESB ?
I am getting the following exception while connecting a soap service using wso2proxy service

Can anyone help me on this please.. For more information please have a look into this. (How to send a soap request(xml) to soap service using wso2 proxy service)
Added the Error Screeshot,Please have a look into this
Fixed the issue and Below are the final configurations
My axis2.xml configuration as Jean Told ( I'm currently testing with NIO, therefore I've removed standard repository/conf/axis2/axis2.xml and renamed repository/conf/axis2/axis2_nhttp.xml to repository/conf/axis2/axis2.xml in my WSO2 ESB v4.8.1 then you edit this new axis2 conf file and search for transportSender name="http" and inside the node transportSender)
<transportSender name="http" class="org.apache.synapse.transport.nhttp.HttpCoreNIOSender">
<parameter name="non-blocking" locked="false">true</parameter>
<parameter name="http.proxyHost" locked="false">proxy.abc.com</parameter>
<parameter name="http.proxyPort" locked="false">8080</parameter>
</transportSender>
Then My proxy service configuration
********Changed my proxy service Configuration like below answer *****
`<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse"
name="CelsiusToFahrenheitService"
transports="https,http"
statistics="disable"
trace="disable"
startOnLoad="true">
<target>
<inSequence>
<property name="messageType" value="text/xml" scope="axis2"/>
<property name="Proxy-Authorization"
expression="fn:concat('Basic', base64Encode('INDIA\username:pwd'))"
scope="transport"/>
<property name="POST_TO_URI" value="true" scope="axis2"/>
<property name="DISABLE_CHUNKING" value="true" scope="axis2"/>
<header name="Action"
value="http://www.w3schools.com/webservices/CelsiusToFahrenheit"/>
<send>
<endpoint>
<address uri="http://www.w3schools.com/webservices/tempconvert.asmx"
format="soap11"/>
</endpoint>
</send>
</inSequence>
<outSequence>
<property name="messageType" value="text/xml" scope="axis2"/>
<send/>
</outSequence>
</target>
<description/>
</proxy>`
Then i restarted the ESB ,then went to try this service in wso2 console as well as using Rest Client(Mozilla Firefox Addon),got the resposne successfully
Thanks alot Jean-Michel for helping this task
You will find the way to configure WSO2 here.
In /repository/conf/axis2/axis2.xml, edit the transportSender configuration of the http transport to specify the proxy server as follows:
<transportSender name="http" class="org.apache.synapse.transport.nhttp.HttpCoreNIOSender">
<parameter name="non-blocking" locked="false">true</parameter>
<parameter name="http.proxyHost" locked="false">proxyhost.yourdomain</parameter>
<parameter name="http.proxyPort" locked="false">proxyport</parameter>
</transportSender>
In the Synapse configuration of the proxy service that sends messages to this proxy server, set the following two properties before the send mediator:
<syn:property name="Proxy-Authorization" expression="fn:concat('Basic', base64Encode('userName:password'))" scope="transport"/>
<syn:property name="POST_TO_URI" value="true" scope="axis2"/>
Sample proxy to test tempconvert service :
<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse" name="CelsiusToFahrenheitService" transports="https,http" statistics="disable" trace="disable" startOnLoad="true">
<target>
<inSequence>
<property name="messageType" value="text/xml" scope="axis2"/>
<property name="Proxy-Authorization" expression="fn:concat('Basic', base64Encode('DOMAIN\user:pass'))" scope="transport"/>
<property name="POST_TO_URI" value="true" scope="axis2"/>
<property name="DISABLE_CHUNKING" value="true" scope="axis2"/>
<header name="Action" value="http://www.w3schools.com/webservices/CelsiusToFahrenheit"/>
<send>
<endpoint>
<address uri="http://www.w3schools.com/webservices/tempconvert.asmx" format="soap11"/>
</endpoint>
</send>
</inSequence>
<outSequence>
<property name="messageType" value="text/xml" scope="axis2"/>
<send/>
</outSequence>
</target>
<description/>
</proxy>
In WSO2 ESB console, click on "Try this service" and enter this request :
<CelsiusToFahrenheit xmlns="http://www.w3schools.com/webservices/">
<Celsius>20</Celsius>
</CelsiusToFahrenheit>
