Mobile Tip: Dynamic REST API URLs in AngularJS Apps


Dynamic URLs are very common in any mobile app. When building AngularJS apps with there are few ways to make parts of the URL (or even the entire URL) dynamic. We’ll use this URL for our example:{id}/edit , where the {id} part should be dynamic.

  1. First of all, you can use the Settings service to perform dynamic substitutions:
    1.  Create a new Settings service (if you don’t have one yet) by going to CREATE NEW > Service > Settings (REST settings).
    2. Then, create a new id parameter in the newly-created Settings and provide a value for it.
    3. Now, go to your REST service, and change the dynamic part of your URL to {} where MySettings is the settings service name, and id is the name of the parameter. Your URL should look like: {}/edit
  2. Alternatively, you can create request parameters directly in the REST service. They will be automatically substituted if names coincide. You can use this approach if you need visual Mapping for dynamic parameters:
    1. Go to your REST service Request > Query String.
    2. Create the new id parameter and provide a value for it.
    3. Change the REST service URL to{id}/edit.
    4. Because the value of the id parameter will be automatically inserted to the {id} placeholder, it won’t be added to the end of the URL as a query string.
