Reading query strings from GET inside Spring web flow

Question

Hy.

Im continuing a spring web flow, using execution key. (an order paypal payment) and would need to read query strings from get. &TokenID and &PayerID

this is how the URL looks like where Paypal redirects user after confirming payment:

/sampleflow?execution=e1s1&_eventId=approved&token=EC5D7416956W8431713&PayerID=TN2RE8ZTH67JN

if eventID is approved, my flow redirects to a payment confirmed state. This part is working. I just need to get the query string parameters somehow.

Any way to do this?

Was it helpful?

Solution

I'm assuming you are trying to access the request parameters in the flow definition xml file. You can access the params using the EL variable requestParameters. 

<evaluate expression="someService.doSomething(requestParameters.TokenID, requestParameters.PayerID)" />
