service call out policy not working with request content-type as application/x-www-form-urlencoded

[rohitmonga]

Service call out policy not able to recognise first and last value of request body with request content-type as application/x-www-form-urlencoded.

Example :

http://example.com/v1/token

content-type: application/x-www-form-urlencoded

Body: client_id=0oa3oxptqqWDPHNas1t7&grant_type=authorization_code&code=Qpq_JKePwfZpuhaQRv5P&client_secret=jjvrJ65blf2Ub1gPu-iutZKRiOhbsFVT5JvH1l3N&redirect_uri=http://localhost:8080/

I am getting error for client_id is required field even though I am passing it.

If I change request with some dummy value as first attribute then its able to get client_id.

Body: dummy=dummy1&client_id=0oa3oxptqqWDPHNas1t7&grant_type=authorization_code&code=Qpq_JKePwfZpuhaQRv5P&client_secret=jjvrJ65blf2Ub1gPu-iutZKRiOhbsFVT5JvH1l3N&redirect_uri=http://localhost:8080/

With above request have first value as dummy then service call out is able to get client_id.

I would suggest using 'FormParams' while sending the values for 'Content-Type: application/x-www-form-urlencoded', also it is good coding practice to not hard code sensitive information such as credentials directly into code.

You can pass the value as below:

<FormParams>

<FormParam name="client_id">{clientId}</FormParam>

<FormParam name="client_secret">{clientSecret}</FormParam>

<FormParam name="grant_type">{grantType}</FormParam>

</FormParams>

Hi,

This works for me :

<Set>
	<Payload contentType="application/x-www-form-urlencoded" variablePrefix="$" variableSuffix="%"><![CDATA[Request Body Here]]>
	</Payload>
	<Verb>POST</Verb>
</Set>

Thanks for this. CDATA sections FTW.

And also, you don't need the variablePrefix and variableSuffix.

you can do this:

<Set>
	<Payload contentType="application/x-www-form-urlencoded">
           <![CDATA[Request Body Here]]>
	</Payload>
	<Verb>POST</Verb>
</Set>
