Converting an Existing Application to a REST Application
When using the the legacy approach, consider one of the following approaches to transform the existing application to a REST application:
Refactor your existing services into
_get,
_put,
_post,
_patch and
_delete services.
Use the invoke directive, as shown in the following example:
For existing applications that use the invoke directive, you can update a service to call the pub.flow:getTransportInfo service and then perform a branch on /transport/http/method to execute the appropriate portions of your existing code, as in the following example:
Note: If you use the invoke directive, you cannot use the $resourceID and $path pipeline variables. In addition, you cannot use the _default service.
