Parsing FORM-ENCODED parameters with GRAILS (chargify webhooks)

Question

I have a GRAILS 3 controller that receive an HTTP post from a webservice (Chargify) with this format (the payload section has about 100 entries with a lot of sub-fields):

POST / HTTP/1.1
Accept: */*; q=0.5, application/xml
Accept-Encoding: gzip, deflate
Content-Type: application/x-www-form-urlencoded
X-Chargify-Webhook-Id: 81309408
X-Chargify-Webhook-Signature: xxxxxxxxxxxxx
X-Chargify-Webhook-Signature-Hmac-Sha-256: yyyyyyyyyyyyyy
Content-Length: 48
User-Agent: Ruby
X-Newrelic-Id: xxxxxx
X-Newrelic-Transaction: aaaaaaaaaaaaaa=
Host: myhost.test.it

id=81197881&event=statement_settled&payload[site][id]=12345&payload[site][subdomain]=test-sandbox

Is there any way with GRAILS to parse the "payload" part and convert it dynamically to a POJO (or also a simple hashmap)?. Chargify use this strange format not recognized by GRAILS framework and I'm unable to parse it automatically.

Is there anyone to help me for parsing? Advance thanks for helping.

Answer 1

Can you try this ?

def readChargify() {
    String requestData = request.reader.text
    def reqMap = org.grails.web.util.WebUtils.fromQueryString(requestData)
}

This Java library to parse the body of webhooks was contributed by another Chargify customer and may be helpful:
