Using an APIC Trigger

Prerequisites

You have created an API group, for example, APIConnect_test. For details, see Creating an API Group.

Creating an APIC Trigger

1. Log in to the FunctionGraph console, and choose Functions > Function List in the navigation pane.
2. Click Create Function.
3. Set the following parameters:
   • Function Name: Enter a function name, for example, apig.
   • Agency: Select Use no agency.
   • Enterprise Project: Select default.
   • For Runtime, select Node.js 10.16.

4. Click Create Function.

6. Configure the trigger information.

   Table 1 Trigger information

   Parameter	Description
   Trigger Type	Select API Connect (APIC).
   API Instance	Select an instance. If no instance is available, click Create Instance.
   API Name	Enter an API name, for example, API_apic.
   API Group	An API group is a collection of APIs. You can manage APIs by API group. Example: DEFAULT.
   Environment	An API can be called in different environments, such as production, test, and development environments. APIG supports environment management, which allows you to define different request paths for an API in different environments. To ensure that the API can be called, select RELEASE.
   Security Authentication	There are three authentication modes: App: AppKey and AppSecret authentication. This mode is of high security and is recommended. For details, see App Authentication. IAM: IAM authentication. This mode grants access permissions to IAM users only and is of medium security. For details, see IAM Authentication. None: No authentication. This mode grants access permissions to all users. Select None.
   Protocol	There are two types of protocols: HTTP HTTPS Select HTTPS.
   Timeout (ms)	Enter 5000.

7. Click OK.
   

   After the trigger is created, an API named API_apic is generated on the APIG console. You can click the API name in the trigger list to go to the APIG console.

Invoking the Function

1. Log in to ROMA Connect, find the selected instance (for example, Ac6-instance-NoDelete), and view the public IP address.
2. Enter the public IP address in the address box of the browser.
3. After the function is executed, a result is returned.

Viewing the Execution Result

1. Return to the FunctionGraph console. In the navigation pane, choose Functions > Function List.
2. Click the name of the nodejs-test function.
3. On the displayed function details page, click the Logs tab to query the function running logs.
4. Click View Context in the same row as a log to view log details.
