Offline application support

摘要

An offline support system operates to record a plurality of request/response pairs exchanged between an application and a web service. The system determines if a current request from the application can be communicated to the web service. Upon a positive determination, the current request is passed to the web service. Upon a negative determination, a most recent recorded request/response pair having a request matching the current request is identified. The response from the identified pair is passed to the application as if it were a response to the current request.

1. An offline application support system comprising a non-transitory computer readable resource storing instructions that, when executed, cause a processing resource to:
record in a repository a plurality of request/response pairs exchanged between the application and a web service, the repository searchable using a current request from the application to the web service as a key; determine if a data connection exists to allow the current request from the application to be communicated to the web service; upon a positive determination:
pass the current request to the web service; andupdate the repository to include a request response pair for the current request and its corresponding response; and upon a negative determination:
examine the current request for an exception indicator indicating that no recorded request/response pair is to be returned to the application, the exception indicator being at least one of includes at least one of a flag included in the request and a type of the request;if the examination does not identify the exception indicator in the current request, identify a most recent recorded request/response pair having a request matching the current request and passing the response from the identified pair to the application as if the response from the identified pair were a response to the current request; andif the examination does identify the exception indicator in the current request, pass the current request to an exception handler rather than obtaining and passing the response from the identified pair to the application.
