First, I will briefly introduce the synchronous interface and asynchronous interface

What is a synchronization interface

Synchronization interface means that the sender sends Message after , After processing, the interface will immediately return the execution result to the sender , This is the synchronization interface .

Synchronous interface is mostly used for small amount of data , A system that can process and return results immediately .

What is an asynchronous interface

Asynchronous interface means that the sender sends Message after , The interface party will immediately return whether the information is successfully received , General status is 202 Accepted, But the receiver is receiving Message after , Not immediately , Or it takes some time to implement , There is no way to return the execution result immediately , A relatively perfect interface will be implemented after , Then request the sender interface , Return the data to , Some interfaces require the sender to execute the query again after a certain time , Get the interface execution result .

Asynchronous interfaces are mostly used for data processing , Or a system that requires process processing , such as BPM System .

CPI How to create an asynchronous interface

Now let's talk about the creation steps

First step , We need to create a new IFlow, You can create it yourself , Not detailed here .
The second step , The sender creates a Soap Of Adapter, The parameters are as follows

The following figure is a complete example I created

among Content Modifier2 The sending time of the sender is recorded

Groovy Is a delay code , The delay time is 3 second

Content Modifier1 The sending time after delay is recorded , And created a Body, Send time , Record the delayed sending time

Here's the test

First of all we have Postman Create a connection in , Connect to the asynchronous interface of the test

Above we see , The execution time of the interface is 62ms, Sent body There is no limit , As long as it is consistent with soap canonical body Just go

Then let's see CPI Interface implementation of

As you can see from the picture above CPI This interface implements 3 A second more , But our Postman62ms The implementation has been completed

Let's see Body

In this way, we can simply create an interface for asynchronous execution
