使用wso2 esb 4.0.6将响应转换为纯文本

问题描述

我是Web服务的新手，因此我已经使用wso2 esb 4.0.6通过HTTP/https创建了一个简单的Web服务.现在，我的要求是从响应中删除标记，即我需要纯文本作为响应，下面的代码段将使您对我的要求有一个简短的了解.

I'm new to web-service and somehow I have created a simple web-service over http/https using wso2 esb 4.0.6. Now my requirement is to remove the tag from response i.e. i need plain text in response, below code snippets will give u a brief idea of my requirement.

<case regex="POST">
   <property name="HTTP_METHOD" value="POST" scope="axis2" type="STRING"/>
       <enrich>
     <source type="inline" clone="true">
         <success xmlns="">Your request for subscription is being processed.</success>
     </source>
     <target type="body"/>
    </enrich>
     <header name="To" action="remove"/>
      <property name="NO_ENTITY_BODY" scope="axis2" action="remove"/>
      <property name="RESPONSE" value="true" scope="default" type="STRING"/>
      <property name="ContentType" value="text/plain" scope="axis2"/>
</case>

我可以得到以下回复<success>Your request for subscription is being processed.</success>

我只想从响应中删除<success> </success>标签.

I just want to remove the <success> </success> tags from the response.

预先感谢

推荐答案

可能有点晚了，但是最近我也遇到了这个问题，这就是使它工作的方法.

May be this is bit late, but I too have came across this recently, and here's how you can make it work.

1. 确保在ESB/repository/conf/axis2/axis2.xml中启用了plainTextFormatter.

2. 在您的代理服务中，设置"messageType"属性，如下所示

1. Make sure in ESB/repository/conf/axis2/axis2.xml plainTextFormatter is enabled.

2. In your proxy service set 'messageType' property as shown below

添加有效载荷文本元素.请参阅下面给出的示例代理服务的无序顺序

Add a payload text element. Please refer to the out sequence of the sample proxy service given below

<outSequence>
         <payloadFactory>
            <format>
               <ms11:text xmlns:ms11="http://ws.apache.org/commons/ns/payload">$1</ms11:text>
            </format>
            <args>
               <arg xmlns:ns="http://www.wso2.org/types" expression="$body/ns:greetResponse/return/text()"/>
            </args>
         </payloadFactory>
         <property name="messageType" value="text/plain" scope="axis2"/>
         <log level="full"/>
         <send/>
      </outSequence>

在这种情况下，我对后端服务(HelloService)的响应如下.

In this scenario my response from the backend service (HelloService) is as follows.

<?xml version='1.0' encoding='utf-8'?>
  <soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope">
  <soapenv:Body>
    <ns:greetResponse xmlns:ns="http://www.wso2.org/types">
      <return>Hello World, Test !!!</return>
   </ns:greetResponse>
 </soapenv:Body>
</soapenv:Envelope>

请参见下面有关使用curl命令的GET请求的请求和响应

See below the request and response for the GET request using curl command

curl -X GET "http://localhost:8280/services/TestProxy/greet?name=Test" -v
* About to connect() to localhost port 8280 (#0)
* Trying 127.0.0.1... connected
