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?

I don't understand where the difficulty is. `request.getParameter("token")` will return `"EC5D7416956W8431713"`. — JB Nizet, Nov 04 '12 at 14:24

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)" />

The link above didn't work for me, but I was able to find the relevant page at this address: 4.4.6. requestParameters

I would have commented above, but my fu is still too weak. – Werd May 14 '15 at 18:47
