Hi everyone,

I am trying to make a proxy for soap-to-rest-to-soap. I want to pass the entire request xml as a attribute in json to my target endpoint. My json body should look like as given

{

"body":"<?xml version="1.0" encoding="UTF-8"?><soapenv:Envelopexmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"xmlns:xsd="http://www.w3.org/2001/XMLSchema"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><soapenv:Header>..."

}

It is a sample request I have taken from web.

Kindly guide me for this. Solution provide soon would be appreciated.

Thanks in advance,

Sumit Yadav

ok, I think I understand what you're describing.

In an Apigee proxy, the payload of a request is available via a context variable called "request.content".

The full XML of an inbound soap request is available there. You can't just embed it directly in the right-hand-side of a JSON property, because that XML might have double quotes, and in JSON the double-quotes have to be escaped. Fortunately in the "message template" of Apigee, there is a function you can use, escapeJSON, to make that all work correctly.

So what you could do is

<AssignMessage name='AM-Embed'>
  <IgnoreUnresolvedVariables>false</IgnoreUnresolvedVariables>
  <Set>
    <Payload contentType='application/json'>{
  "body": "{escapeJSON(request.content)}"
}
</Payload>
  </Set>
</AssignMessage>

This is the result I see

{
  "body": "<soap:Envelope xmlns:wsse=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd\"               xmlns:wsu=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd\"               xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\"> <soap:Header>    <wsse:Security>      <wsu:Timestamp wsu:Id=\"Timestamp-7cd6d5e5\">        <wsu:Created>2020-08-04</wsu:Created>      </wsu:Timestamp>    </wsse:Security>  </soap:Header>  <soap:Body>    <Operation>      data here    </Operation>  </soap:Body></soap:Envelope>"
}

Check it out, all of the double-quotes are escaped as we wanted.

The converse, extracting the right-hand-side of a JSON property into ... the request content, which you must do on the response side, is a little different because you must un-embed a string from the full content.

The full content of the response comes back and you want to get just one piece of it, a subset of it.

To do that you need to use jsonpath to reach into the JSON. Fortunately, again, there is a function for that in the message template. This is what it looks like:

<AssignMessage name='AM-UnEmbed'>
  <IgnoreUnresolvedVariables>false</IgnoreUnresolvedVariables>
  <AssignVariable>
    <Name>jpath1</Name>
    <Value>$.body</Value>
  </AssignVariable>
  <Set>
    <Payload contentType='application/xml'>{jsonPath(jpath1,response.content)}</Payload>
  </Set>
</AssignMessage>

Doing it that way gets you the XML. There's no need to "unescape" the quotes - that happens automatically.
