json rest wso2 wso2esb ampersand

Cómo pasar el ampersand en json body en wso2 esb



rest wso2esb (2)

Tengo un problema al pasar un signo comercial dentro de un valor JSON de cuerpo al llamar a una API REST en WSO2 esb , se da una excepción. Pero necesito pasar este valor ''&'' al backend a través de esb y no como & .

Traté de enviarlo de las siguientes maneras, pero no tuve éxito.

  • &
  • valor codificado de url
  • valor hexadecimal

Porfavor ayudame a resolver este problema.

Esta es la excepción que obtuve.

He intentado lo mismo con los registros de conexión habilitados y funcionó para mí sin ningún cambio. ¿Cuál es la versión de ESB que probaste? Si habilitó los registros de conexión, verá qué viene y qué sale de la siguiente manera. Agregué & symbol to body parameter.

Intenté lo mismo en ESB 4.8.1 también. Desde que vi los errores de script java en su registro de errores también agregué el mediador de script java. Por favor, consulte la muestra de API a continuación.

<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>

Entonces envío la solicitud de la siguiente manera.

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

Puedo ver que mis valores pasan al final correctamente. Solo para verificar que agregué TCPMon entre ESB y back-end para verificar el mensaje de salida. Está volviendo con & signo. Los registros de cables están aquí y también se adjunta la salida de TCPMon.
