  • First, I want to create a common proxy service class with HTTP verbs with unique signatures so that they can be used for all types of service requests throughout the application.
  • Below is the sample code snippet for the common proxy service class where we can define HTTP verbs with different signatures.
  • Now, the created common proxy service class needs to be registered to a root module.
  • Once the common proxy service is created and registered in the root module, we can use it in any service creation by simply importing and injecting it as a dependency injection in the constructor of the newly created Service class.
  • Below is the sample code snippet for the service class creation and utilization of the common proxy service class inside newly created service class.

  • AngularJS sanitizes untrusted values for HTML, styles, and since URLs contain arbitrary code; sanitizing resource is not possible.
  • For example that the following template needs to bind a URL to a javascript:alert(…) call: – – Ideally, Angular automatically sanitizes the URL and it disables the dangerous code in development mode and logs this action to the console.
  • It is therefore suggested to call a method on the controller for constructing a trusted video URL, which causes Angular to allow binding into
