Handling
multiple responses dynamically in ICS Orchestration:
We are using one REST Web Service for which we will
get two different responses based on availability of tables for a given time.
Use
case: Get the available tables for a given time.
Request
Parameters:
Restaurant
ID: 642346,
Time:
10:00
(Along with above parameters some other parameters
are required which are common for all requests.)
Response1:
For the given time if tables are available, the response is
{
"RestaurantId": 642346,
"AvailableTables": 3
}
Response2:
For the given time if tables are not available, the response will be
{
"StatusCode": 3,
"Status": "Tables are not available for given
timeslot."
}
Solution:
New
Integration -> Orchestration (Give the required details like name etc)
1. Trigger: In
orchestration drag a Sample REST trigger
Endpoint -> Provide all required details -> In response tab choose a
file which is a combination of multiple response like below
Sample JSON file:
{
"RestaurantId": 642346,
"AvailableTables": 3,
"StatusCode":
3,
"Status": "Tables are
not available for given timeslot."
}
Provide above four attributes as a json file in
above wizard.
2.
Invoke:
Drag
a REST invoke endpoint connection and provide the same response file as above.
So as of now two connections were configured in
our orchestration, the diagram will be looks like below
3. Map the request parameters:
4. Map the response parameters:
5. Configure Switch action :
In order to use multiple
responses in one orchestration we need to write a condition in switch to route
the response dynamically.
Switch
Condition:
In our scenario the StatusCode
attribute value is 3.
So we can use status
code as a condition here.
è Drag
the statusCode attribute from response attribute.
è Provide
the value as 3.
The above condition is used to route the response
based on statuscode if the status code is 3 it will go to the first route
otherwise it will go to below route.
5.1 Drag a Map from actions for first
response:
5.2 Drag a Map from actions for
second response:
The final orchestration is shown in below figure
