Appending keycode to Path on Request URL via Assign Message Policy

[dinogregorich]

I have created a proxy that has a target url to a third party. I purchased a user code, that is required at the end of the path, not as a query parameter.

Example: https://this.url.com/{{input}}/{{my user code}}

I want to provide this to my customers, but I want to hide my user code. I had thought I could append it to the request like we do with query parameters, but I cannot find an Add Path, or Append Path options in the Assign Message Policy.

For example, I want my customer to see in the swagger spec the only what they need to input. I want them to send to my proxy https://this.url.com/123456

then in the proxy I wish to append the user code like this: https://this.url.com/123456/abcdefg What is the best way to accomplish this?

It can be done via Assign Message Policy or a simple Javascript policy. So how are you going to get the my_user_code value?

• Is it hardcoded or a dynamic value?
• If dynamic how do you get it in the proxy?

Sample JS code, it should change based on your proxy design,

I assume the values are extracted from extract variable policy,

var input = context.getVariable("urirequest.input");
var user_code= context.getVariable("urirequest.user_code");

if(user_code !== null ){
  var targeturl = context.getVariable("target.url");
  context.setVariable("target.url", targeturl+"/"+ input +"/"+ user_code);
}

Thank you! The customer provided the product code in the path, I have a fixed account code that I appended. This allows me to abstract away my code from the customers.

This is the JavaScript Policy added to the Target Endpoint Preflow:

var targeturl = context.getVariable("target.url");

var path = context.getVariable("proxy.pathsuffix");

context.setVariable("target.url", targeturl+"/"+path+"/my code");

It worked great! Thanks for your help.
