body()

string body([string request-id])

The body function provides access to an upstream response body. The result is the raw body – if needed, parsing has to be done explictly.

When called without a parameter, the function returns the body for the request with the ID main, which is the default ID for an upstream request.

Example

<flow>
<request>
{"url": "https://example.com/json"}
</request>
<request>
{"id": "xml", "url": "https://example.com/xml"}
</request>
<eval out="$json">json-parse(body())</eval>
<eval out="$dom">xml-parse(body('xml'))</eval>
</flow>
