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  8   2    json/ rest/ wso2/ wso2esb/ ampersand

问题描述

I have an issue when passing ampersand inside a JSON body value when calling a REST API on WSO2 esb , it gives an exception. 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。 But I need to pass this '&' value to the backend via esb and not as & 但是我需要通过esb将这个“＆”值传递给后端而不是& . 。

I tried to send via the following ways, but didn't get any success. 我尝试通过以下方式发送，但没有取得任何成功。

  • &
  • url encoded value 网址编码值
  • hexadecimal value 十六进制值

Please help me to solve this issue. 请帮我解决这个问题。

This is the exception which I got. 这是我得到的例外。

I have tried same thing with wire logs enabled and it worked for me without any changes. 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。 What is the ESB version you tried. 您尝试过的ESB版本是什么？ If you enabled wire logs you will what comes and what goes out as follows. 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。 I added & symbol to body parameter. 我在body参数中添加了＆符号。

I tried same in ESB 4.8.1 as well. 我也在ESB 4.8.1中尝试过相同的操作。 Since i saw java script errors in your error log i added java script mediator as well. 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。 Please see sample API below. 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>

Then i send request as follows. 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

I can see my values pass to back end properly. 我可以看到我的值正确传递到后端。 Just to verify i added TCPMon between ESB and back end to verify out going message. 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。 Its going back with & sign. 它带着＆符号返回。 Wire logs are here and TCPMon output also attached. Wire日志在此处，并且还附加了TCPMon输出。
