Note All the other requests need process id first.

2 Get data value of flow. Access the URL.

▪ Field:

http://localhost:8080/TestRestChannel/rest/flows/restChannelFlow/FUBNHCDMCUBTACEPDFCTFREOCDETAFEUABIAFMIA/stringDataFL

It returns string.

▪ KColl:

80/TestRestChannel/rest/flows/restChannelFlow/FUBNHCDMCUBTACEPDFCTFREOCDETAFEUABIAFMIA/restKcollFL/stringDataFL

▪ IColl: there are two ways.

▪ IColl: get all the data of IColl

http://localhost:8080/TestRestChannel/rest/flows/restChannelFlow/FUBNHCDMCUBTACEPDFCTFREOCDETAFEUABIAFMIA/listFL

▪ IColl:

http://localhost:8080/TestRestChannel/rest/flows/restChannelFlow/FUBNHCDMCUBTACEPDFCTFREOCDETAFEUABIAFMIA/listFL/0

It returns json string.

▪ Context:

http://localhost:8080/TestRestChannel/rest/flows/restChannelFlow/FUBNHCDMCUBTACEPDFCTFREOCDETAFEUABIAFMIA

3 Edit the value of data in flow. Access the URL.

▪ Field:

▪ URL:

http://localhost:8080/TestRestChannel/rest/flows/restChannelFlow/FUBNHCDMCUBTACEPDFCTFREOCDETAFEUABIAFMIA

▪ Content type: application/json

▪ Input example: {"stringDataFL":"hello"}

▪ KColl: there are two ways.

▪ Edit all the values:

▪ URL:

http://localhost:8080/TestRestChannel/rest/flows/restChannelFlow/FUBNHCDMCUBTACEPDFCTFREOCDETAFEUABIAFMIA/restKcollFL

▪ Content type: application/json

▪ Input example: {"dataString":"hello"}

▪ Result: restKcollFL has only {"dataString":"hello"} and other data are lost.

▪ URL:

http://localhost:8080/TestRestChannel/rest/flows/restChannelFlow/FUBNHCDMCUBTACEPDFCTFREOCDETAFEUABIAFMIA

▪ Content type: application/json

▪ Input example: {"restKcollFL":{"stringDataFL":"hello"}}

▪ Result: The KColl with index 0 in listFL would change to {"dataString":"hello"} and other data are lost.

4 Move to the next state of flow. Access the URL.

http://localhost:8080/TestRestChannel/rest/flows/restChannelFlow/FUBNHCDMCUBTACEPDFCTFREOCDETAFEUABIAFMIA

Input: {"dse_nextEventName":"toNextEvent"}

Note dse_nextEventName is the parameter of system and toNextEvent is the next event name of the state.

5 Delete elements in flow. Access the URL.

▪ Field:
