如何在wso2 esb中传递json体中的＆符号

[英]How to pass ampersand in json body in wso2 esb

 原文  2016-08-10 03:28:53  2   2    json/ rest/ wso2/ wso2esb/ ampersand

问题描述

在WSO2 esb上调用REST API时，在JSON体值内传递＆符时出现问题，它会出现异常。 但是我需要通过esb将这个“＆”值传递给后端而不是& 。

我尝试通过以下方式发送，但没有取得任何成功。

  • &
  • 网址编码值
  • 十六进制值

请帮我解决这个问题。

这是我得到的例外。

我已经尝试使用有线日志同样的东西，它没有任何变化对我有用。 您尝试过的ESB版本是什么？ 如果您启用了线路日志，那么您将会发生什么以及如下所示的内容。 我在body参数中添加了＆符号。

我也在ESB 4.8.1中尝试过相同的操作。 因为我在错误日志中看到了java脚本错误，所以我也添加了java脚本调解器。 请参阅下面的示例API。 

   <api name="TestAPI" context="/test">
      <resource methods="POST" url-mapping="/status" faultSequence="fault">
         <inSequence>
            <script language="js">var symbol = mc.getPayloadXML()..*::password.toString();
               mc.setPayloadXML(
                  &lt;m:getQuote xmlns:m="http://services.samples/xsd"&gt;
                     &lt;m:request&gt;
                        &lt;m:symbol&gt;{symbol}&lt;/m:symbol&gt;
                     &lt;/m:request&gt;
                  &lt;/m:getQuote&gt;);</script>
            <send>
               <endpoint name="test-I_APIproductionEndpoint_0">
                  <http uri-template="http://127.0.0.1:8888/"/>
               </endpoint>
            </send>
         </inSequence>
         <outSequence>
            <send/>
         </outSequence>
      </resource>
   </api>

然后我发送请求如下。 

curl -v -X POST -H "Content-Type: application/json" -d '{"username":"xyz","password":"xyz & abc"}' http://127.0.0.1:8280/test/status

我可以看到我的值正确传递到后端。 只是为了验证我在ESB和后端之间添加了TCPMon来验证输出消息。 它带着＆符号返回。 Wire日志在此处，并且还附加了TCPMon输出。
