Is it possible to make the Content-Type Value configurable?

[#1]

We want to make Content-Type value as configurable and store as an entry in KVM Map. And want to call the configurable parameter in the policies like Assign Message policy for setting JSON payload / XML payload as per the requirement. But while doing so, we were getting an error during the deployment of the code. Is it possible to make the Content-Type configurable? Need suggestion on this.

hi @Suranjit Kashyap,

This is very much possible by Assign Message policy. Pl upload the bundle.

Cheers,

[#3]

cannot upload bundle here as it is project specific. Can you please let me know the process, need to be followed to make the content-type configurable and call the configurable parameter in Assign Message policy?

[#4]

Add / Set header as applicable as given:

<Header name="Content-Type">{var}</Header>

[#5]

Thanks!! Setting Header is fine. In my description, I have specifically mentioned while setting payload JSON/XML we need to pass content type. Can we call the config parameter in this? - <Set><Payload contentType={var}></Set>. I have tried this but couldn't deploy the code.

Hi @Suranjit Kashyap

Can you try the below code for your requirement.

<Payload contentType="{var}"></Payload>

Above answer should work, Please find attached proxy that demonstrates same.

@GargiTalukdar

while doing so, it is not allowing me to deploy the code and throws an error while deploying the proxy itself.

@Suranjit Kashyap , Error might be somewhere else. Take a look at above proxy i have attached. It demonstrates exactly the answer you are looking for. Are you onPremises / cloud ?

[#10]

On-Premise

@Suranjit Kashyap , What's the onPremise version ? It might not be available as a feature in older version of onPremises. You need to fallback to approach suggested by @rdoda ,

    <Set>
        <Headers>
      		<Header name="contentType">{contentTypeValue}</Header>
	</Headers>
        <Payload>
          {"name":"foo", "type":"bar"}
	</Payload>
    </set>	

[#12]

We are using CI tool (Jenkins) to deploy the proxy and there it is failing with the below error: Open quote is expected for attribute "contentType" associated with an element type "Payload" during the execution of install-bundle maven plugin. current version of On-Premise - 4.16.01.01

[#13]

one more concern regarding the example you showed. Header and Payload is completed different. Header name should be named as Content-Type and <Payload> tag without giving mandatory attribute "contentType" will not work I guess.

@Suranjit Kashyap , Above examples works in cloud. You might need to update your Apigee onPrem version to the latest to verify same.

[#15]

@Anil Sagar, That might be the case. Thanks!!

[#16]

@Anil Sagar, I have checked again. calling the configurable variable in <Payload> tag didn't worked for the version I am using 4.16.01.01. But the template provided by you to set the header separately in <Header> tag and calling the configurable value worked for me. Thanks you and everyone for your valuable suggestions.
