Question

在WSO2 esb上调用REST API时，在JSON正文值中传递＆符号时出现问题，它会出现异常。但我需要通过这个'＆amp;'通过esb而不是&的后端值。

我尝试通过以下方式发送，但没有取得任何成功。

&
url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。

我已尝试启用有线日志，但它对我没有任何改动。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。我添加了＆amp;符号到身体参数。

Answer 2

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。它回归＆amp;标志。有线日志在这里，TCPMon输出也附加。
