What is correct about using context variables in Gatewayscript policies?

Acontext.set('my.vars.amount', 100) generates { 'my.vars': { 'amount': 100 } }

BAll API context variables are saved in an XML tree.

Ccontext.message.statuscode = '200 Success' updates the status code of the message object.

Dcontext. request. statuscode = 400 updates the status code of the request object.

Show Suggested Answer

Suggested Answer: A

Setting Context Variables: In Gatewayscript policies, thecontext.setfunction is used to set context variables. The syntaxcontext.set('my.vars.amount', 100)creates a JSON structure wheremy.varsis an object containing the keyamountwith the value100.

JSON Structure: This method of setting context variables generates a JSON structure, which is a common format for data interchange in APIs. The resulting structure would be{ 'my.vars': { 'amount': 100 } }.

Usage in Policies: This approach allows for easy manipulation and access to variables within the GatewayScript, facilitating dynamic API behavior based on the context.

Documentation Reference: According to the IBM Certified Solution Implementer - API Connect v10.0.3 documentation, usingcontext.setin this manner is the correct way to generate the specified JSON structure1.

I always get these context variable questions mixed up. Maybe I should just start guessing randomly.

Wait, so we can't use context.request.statuscode? That's going to make my life a lot harder.

I disagree, I believe C) is correct because it updates the status code of the message object.

Option D is incorrect. The context.request.statuscode property does not exist, it should be context.message.statuscode.
